Why Austen bores the modern audience Essay Example for Free
Why Austen bores the modern audience Essay But the scenario with Darcy and his two proposals counters this philosophy, and makes an extremely discreet statement. Alternatively There must be something that makes the novel a universally acknowledged classic. Here are some of the ways Jane Austen attempts to quell boredom In contemplating this, it must be taken in mind that social attitudes were at a peak of mildness and placidity in the Victorian period (table legs = table unmentionables); much less was required to imply passion to the reader (this rather paradoxically Victorians must have needed much dirtier minds). In the complete book I dont think there is one romantic physical gesture cited; even the language goes little further than expressing how cheerful the speaker is (I was utterly delighted); but when Austen does want to construct specific atmospheres she demonstrates a range of artistic techniques to achieve this: inside the first chapter of the third volume there is a scene possessing an excitement foreign to the rest of the book. Austen introduces Darcy back into the story without any real preceding apprehension: while the former was conjecturing as to the date of the building, the owner of it suddenly came forward from the road, which led behind it to the stables. This remark is so subtle that it takes a few seconds to contemplate what has actually happened in that respect we share exactly the feelings that Elizabeth must be experiencing. Various dialogues in the preceding volume give the impression that there is no danger of Darcys materializing; and the consistent tepidity of the novel assure us that Austen wouldnt stoop so low as to fabricate a coincidence like this that when it does happen it seems ingenious. There are some attractive and imaginative narrative techniques inside the book which momentarily quench the monotony, and when I read the fourth chapter of the third volume, I have to confess that I was intrigued. The chapter is narrated on the behalf of a character other than the main focus of the story (Elizabeth), in the standard form of a letter. But interestingly, there are two correspondences making up the chapter, one composed a day after the other; which is a rational way to break up the continuity of the story and thus generate some much required tension. The form of the novel three separate volumes could have several motives: printing restraints, a desire to make more money, writers block (more time to keep the publishers happy)* or genuine artistic consideration. Indeed, the events fit pretty tidily into three sections, with cliff-hangers at the end of the preceding two (will they stay in London oh, they will; what will happen when they get to Mr. Darcys house Theyll theyll meet Mr. Darcy). The book has a standard relationships-problems-weddings structure. Jane Austens choice of language is pretty limited to the rigid and self-important vocabulary necessitated by the presence of upper-class Victorian females (vexed, delighted, utterly ); she employs this to great effect though, probably owing to her own circumstances. Aside from the abovementioned portentous dispatch there are some instances of words employed for a specific effect: Darcys letter in chapter twelve of the second volume is a good example Austen writing on behalf of an apologetic and mildly arrogant rejectee. Darcy pleads her justice in perusing his countenance, and he offends her out of necessity. The previous example especially is both humble and superior: he only insults her because he is forced to; nevertheless he is taking a liberty by considering a necessity to affront. (I resisted an urge here to cross reference Jane Austen with Catherine Tate. Its obvious who the real genius is ) Patterns of words are exploited throughout; recurrently the phrase structure of the adverb most followed by an adjective in creating speech for the fairer sex: most displeased, most agitated, etc. The effect achieved is much the same as the abovementioned an upper-class verbalization. The spectrum of emotional effects throughout the whole book is small. From the depiction of mild anticipatory discomfort to the fairly strong sense of awkwardness portrayed in Elizabeths meetings with Darcy subsequent to the receiving of the explanatory letter, there is no contrast harsh enough for us to relate in any significant way to the characters happiness at the end of the story. In conclusion, despite my judgment of this book as an uneventful, upper-class, pretentious, boring novel so distant from todays morals as to be almost surreal; which only approaches the mildly amusing in the half-hearted humour directed at the un-funny comments by Mr. Bennet above; I can go as far to say that when compared with the two greatest writers of her era, Austen has a comfortable top-three placement.

Nervous Systems And Sensory Organs
Nervous Systems And Sensory Organs You take a needle and prick your finger, your response is probably to get your finger away from the needlepoint quickly and maybe yell ouch. You take the same needle and poke a protist, sponge, cnidarian, or worm with it and they will all probably exhibit a similar response, at least they will all retreat. But how can this be possible? Protists are unicellular organisms that dont have a system to communicate after coming in contact with a stimulus. Similarly, sponges just sit on a rock all day, they also dont have any nervous functions. Cnidarians on the other hand have a nerve net, but how do they coordinate responses without a brain? All of these questions, along with how body plans relate to nervous system evolution, will be answered as this paper explores the evolution of the nervous system and sense organs from protists to the vertebrates. The Protists The classification of protozoans has been changed a lot through time. Cavalier-Smith (1993) came up with what he called the simplest definition of the kingdom Protozoa. They are eukaryotes, other than those that primitively lack mitochondria and peroxisomes, which lack the shared derived characters that define the higher derived kingdoms of Animalia, Fungi, and Plantae (Cavalier-Smith, 1993). Even though protozoans are simple unicellular organisms, they can still respond to many of the same stimuli higher order organisms respond too. Take for example that science class most students have. You put paramecium under a microscope and try to touch them with a probe, or watch their response to the light from the microscope. Most of the time when the anterior membrane of Paramecium is mechanically stimulated the ciliary power stroke reorients so the cell swims backwards, or retreats (Ogura Machemer, 1980). If the posterior membrane is stimulated the cilia beat towards the rear, causing the organism to move forward (Ogura Machemer, 1980). The light from the microscope can affect both the photoreceptors and thermoreceptors of the protists. The unicellular alga Euglena shows two regions of peak sensitivity to light during photokinesis at 465 nm and then again near 630 nm and during phototaxis 490-500 nm (Leys et al., 2002). Euglena is phototactic and its system consists of locomotory flagellum, an eyespot, and a photoreceptor (Gualtieri, 2001). As the organism moves, the eyespot senses the amount of light that reaches it and therefore pushes the Euglena in the direction of more light (Gualtieri, 2001). But moving towards light also means a change in temperature, especially if the light source is close to the organism. Paramecium cells are themo-sensitive and tend to accumulate at temperatures they were cultured at (Toyoda et al., 2009). They become used to their membrane fluidity at this temperature, and small temperatures changes drastically change this fluidity (Toyoda et al., 2001). If the temperatures change too much the Paramecium will retreat away from the heat in order to survive (Hennessey, Saimi, Kung, 1983). Protists also have chemosensory responses to certain odorants and tastes. Rodgers, Markle, and Hennessey (2008) found G-protein coupled receptors in the Paramecium. They tested whether Paramecium and Tetrahymena could respond to the common higher order organisms odorants and tastants (Rodgers, Markle, Hennessey, 2008). If they are affected by the odorants or tastants they will do an avoiding reaction, which can be seen when the organism is leaving an attractant or enters a repellent (Valentine, Yano, Van Houten, 2008). The Tetrahymena was more sensitive and could detect all of the tastants sampled, while Paramecium only detected four or the ten (Rodgers, Markle, Hennessey, 2008). Since Paramecium feed on bacteria Valentine, Yano, and Van Houten (2008) showed that they are attracted to bacterial metabolites such as, folate, acetate, glutamate, cyclic AMP, Biotin, and Ammonium. So an organism without a nervous system or sense organs has the ability to respond to many of the same env ironmental factors that higher order organisms respond too. Poriferia Similar to the protozoans, sponges lack definite body symmetry and also lack nerves and cell junctions, allowing no communication between cells (Leys et al., 2002). Sponges do respond to both light and mechanical stimuli. Recently, some sponges have been found to respond to light by contracting their cilia (Leys et al., 2002). Most larvae, via their cilia, are sensitive to light near 440 nm and again at 600 nm causing them to respond by straightening and bending (Leys et al., 2002). Although sponges lack neurons they are sedimentary feeders and therefore need ways of dealing with excessive particulates in their feeding currents (Tompkins-MacDonald Leys, 2008). Cellular sponges have the ability to close the openings to their incurrent canals, constrict the size of their intake canals, and even carry out a series of slow contractions that expel unwanted material (Tompkins-MacDonald Leys, 2008). The syncytial tissues of glass sponges allow action potentials initiated at single or mult iple sites to propagate through the entire animal, stopping the feeding current (Tompkins-MacDonald Leys, 2008). When Tompkins-MacDonald and Leys (2008) tested this response they found that by probing the interal body wall, allowing light to touch the outer body wall, or by knocking on the outer body wall pumping was stopped. This shows that a sponge, although not having an nerves or cell junctions can still respond to its environment. Cnidaria and Ctenophora Cnidaria and Ctenophora are the most basally branching lineages with specialized sense organs. The Cnidaria are radially symmetrical and have a nerve net where the sensor and ganglionic neurons and their processes are interspersed among the epithelial cells of both layers (Watanabe, Fujisawa, Holstein, 2009). Sensory structures that form part of epidermis are found in all animal phyla. Cnidarian neurons do not cluster to form a central nervous system or ganglia, which is why the nerve net is considered the simplest nervous system (Sarnat Netsky, 2002). In cnidarians sensory structures consist of naked sensory neurons whose dendrite is formed by a modified cilium (Jacobs et al., 2007). Sensilla are individual sensory neurons, or small groupings of sensory neurons, that typically function in one of the following; light detection, mechanoreception, and chemoreception (Jacobs et al., 2007). Photoreception and chemoreception involve G protein-coupled receptors (GPCRs) and membrane ion c hannels, similar to what was observed in the protists (Jacobs et al., 2007). Jacobs et al. (2007) believes that sense organs and kidneys in bilterians may have evolved from groupings of choanocytes in sponges. Cnidarian sense organs are usually associated with the free swimming form that resembles a jellyfish (Jacobs et al., 2007). Neural regionalization is most evident in the medusozoans that have rhopalia , an eye system with lenses (Watanabe, Fujisawa, Holstein, 2009). Other cnidarians contain simple eyes. A statocyst is a dense array of mechanosensory cells that serve as a touch plate (Jacob et al., 2007). In most cnidarians the rhopalia, sense organ, alternate with tentacles, appendages, similar to how vertebrates have organs associated with appendages (Jacobs et al., 2007). Photoreceptors responsible for contractions in Hydra in response to blue light at 470 nm, are consistent in spectral location and shape with a rhodopsin-based photoreceptive system (Leys et al., 2002). One of the newest findings deal with coral larvae and their exterior cilia being able to detect and respond to underwater sound fields (Vermeij et al., 2010). Vermeij et al. (2010) setup six chambers directed towards underwater speakers playing day and night reef sounds. Free-swimming coral larvae moved predominately towards the speakers independent of chamber orientation (Vermeij et al., 2010). This study was done because fish larvae used it as well. Platyhelminthes The flatworms have true bilateral symmetry (Reuter Gustafsson, 1995). Some flatworms have a nerve net like Cnidarians. Others have a central nervous system that consists of anterior ganglia, the brain, and one or several pairs of longitudinal nerve cords that are connected in a ladder-like configuration (Reuter Gustafsson, 1995). The peripheral nervous system is just a meshwork of nerves that are interconnected to the central nervous system (Reuter Gustafsson, 1995). Platyhelminthes has eyes, a light sensing organ, on the dorsal side of the body composed of two cell types: pigment cells and photoreceptor cells (Inoue et al., 2004). The pigment cells form an eye-cup while the visual neurons are located outside the eye-cup (Inoue et al., 2004). The eyes do not allow Planarians to see distinct images, but allows them to be repulsed by bright light, a condition known as negative phototrophism (Hyde, 2003). Not only does the head bear a pair of eyes, but a also a pair of ear-like lobes called auricles. Auricles have nothing to do with hearing; instead they are involved in mechanoreception, chemoreception, and pressure reception (Hyde, 2003). Nematodes Caenorhabditis elegans (C. elegans) has been established as a genetic and genomic model organism (Zhang, 2008). C. elegans does not have a visual or auditory system so it depends on chemosensation to detect bacteria to feed on (Zhang, 2008). C. elegans has exactly 302 neurons, 32 of which are chemosensory because they have ciliated endings that are directly exposed to their external environment (Troemel et al., 1995). Free-living nematodes use amphids and phasmids as sensory structures to seek food and avoid harmful situations, while parasitic nematodes use amphids to actively or passively see a host (Srinivasan, Durak, Sternberg, 2008). Amphids are either enclosed in the amphid sheath or exposed to the environment (Zhang, 2008). Ascaris lumbricoides (A. lumbricoides), a larger nematode, contains 298 neurons (Srinivasan, Durak, Sternberg, 2008). Each group of neurons reacts to certain stimuli. For example, some respond to salt (ASE chemosensory neurons), others respond to volatile al dehydes, ketones, and alcohols (AWC olfactory neurons), and yet others respond to chemical, mechanical, and osmotic stimuli (ASH neurons) (Srinivasan, Durak, Sternberg, 2008; Troemel et al., 1995). Mollusks, Annelids, and Arthropods There are three different nervous systems seen in mollusks alone. Bivalves tend to have no cephalization, while slowing moving mollusks have some cephalization, primary to connect senses and motor information while moving through the environment (Gregory, 2006). The cephalopods require complex sense organs and so they are highly cephalized Gregory, 2006). The cephalopods are known for their well-developed eye, that functions almost exactly like the human eye, which is why they such good eye sight (Oceanic Research Group, 2007). Annelids and Arthropods have repeating segments and an anterior brain. Each segment contains its own ganglion, which controls the muscles of that segment (Gregory, 2006). The nerve cord of both phylum runs directly through all of the segments (Gregory, 2006). These two were grouped together because they are very similar in function for being two different phyla. Vertebrates Amphioxous, part of the phylum chordata, are only capable of a few reflexive responses. They do not have the ability to recognize tactile stimuli, so all stimuli are interpreted as a threat and the organism curls away in defense (Sarnat Netsky, 2002). This reaction demonstrates how neurons that feel the stimuli on one side of the body are transmitted and affect motor neurons on the other side of the body (Sarnat Netsky, 2002). The neuron that served this function was known as the decussating interneuron (Sarnat Netsky, 2002). This is the underlying groundwork of the vertebrate nervous systems. Vertebrates have bilateral symmetry, complex sense organs and complex behaviors, requiring a very cephalized, complex nervous system. Vertebrates consist of two nervous systems, the Central and Peripheral. The central nervous system (CNS) contains the brain and spinal cord, while the peripheral nervous system (PNS) is composed of the nerves running through the body. The CNS has been conservative in its evolution, especially when looking at the senses of the vertebrates (Hodos Butler, 1997). The receptor types are either monopolar or pseudomonopolar neurons, each consist of parallel pathways connecting the receptors to the primary central neurons, which are located inside the sense organs where the stimuli is processed (Hodos Butler, 1997). Nerves are bundles of neurons, without cells bodies (Gregory, 2006). Most nerves contain both sensory and motor abilities (Gregory, 2006). There are both cranial and spinal nerves. There are multiple cranial nerves in all vertebrates, with humans having 12, and they are responsible for both sensory and motor information (Brown, 2003). The nerves are numbered using roman numerals from 1 to 12 (Brown, 2003). Brown (2003) described all of the following cranial nerves. Cranial nerve I is the olfactory nerve and it carries the sense of smell to the olfactory bulb of the brain. Cranial nerve II is the optic nerve and it carries visual information to the brain. Cranial nerve III is the oculomotor nerve and it provides motor ability to the four-extrinisic eye muscles, muscles of the upper eyelid, and intrinsic eye muscles. Cranial nerve IV is the trochlear nerve and it gives motor ability to the superior oblique eye muscle. Cranial nerve V is the trigeminal nerve and it provides sensory info rmation from the face, forehead, nasal cavity, tongue, gums and teeth. Cranial nerve VI is the abducens nerve gives motor ability to the lateral rectus muscle of the extrinisic eye. VII is the Facial nerve that provides humans with facial expressions. VIII is the vestibulocochlear nerve and it innervates the hair cell receptors of the inner ear. IX or the glossopharyngeal nerve moves the pharynx, soft palate, and posterior region of the tongue. X is the vagus nerve, it is the longest nerve, and provides sense transports from the ear to the taste buds to the throat. Cranial nerve XI is the spinal accessory nerve and it is involved in swallowing and powering muscle movement for the upper shoulders, head, and neck. Lastly, XII is the hypoglossal nerve and it moves the muscles of the tongue (Brown, 2003). As you can see the ability for control of all of these senses and movements makes for a very complex nervous, something that was never seen in earlier organisms. The spinal nerves are connected directly to the spinal cord by two roots, the dorsal (strictly sensory) and ventral (strictly motor) (Gregory, 2006). All of the above are seen in the PNS, which is then subdivided into the Somatic and Autonomic Nervous System. The Somatic Nervous System is the voluntary system, including all of the nerves that serve the skeletal muscles and exterior sense organs (Gregory, 2006). Reflexes are also seen in this nervous system. Just like in the lower organisms, vertebrates respond to stimuli. Except vertebrates have a much more complex stimulus-reflex system. Remember how a Paramecium came in contact with a stimulus and retreated until adaptation occurred? Vertebrates have the ability to think about coming in contact with a stimulus, they dont have to come in contact with everything they see because they have the somatic nervous system (Gregory, 2006). The other subdivision is the autonomic nervous system that is responsible for actions without conscious control; examples are heart beating and smooth muscle actions (Gregory, 2006). Everything in the PNS needs a place to send its information too and that is why there is the central nervous system. In the more primitive animals the brain, or ganglia, was there to simply send out reflexes to external stimuli (Gregory, 2006). The vertebrates have evolved a very complex brain because they have the ability to respond to reflexes, hold memory, learn, and think (Gregory, 2006). The brain has three divisions, the hindbrain, midbrain, and forebrain. The important portion when talking about senses is the midbrain because it receives sensory information and sends it to the forebrain to be processed (Gregory, 2006). In fishes and amphibians it is geared towards reflexes associated with visual input (Gregory, 2006). The cerebrum in reptiles, birds, and mammals receives sensory information and coordinates motor responses (Gregory, 2006). There are four lobes the frontal (motor functions), parietal (sensory receptors from skin), occipital (vision), and temporal (hearing and sm elling) (Gregory, 2006). Similar to decussating interneuron in Amphixous, vertebrates have the corpus callosum that contains neurons that cross from one side of the brain to the other, allowing communication between both sides (Gregory, 2006). Conclusion Bioluminescence is when luciferase catalyzes the oxidation of luciferin to excited oxyluciferin that then relaxes to produce a visible photon (Akilesh, 2000). The most common colors for bioluminescence are blue and green, although red and violet can be seen as well (Akilesh, 2000). Bioluminescence was developed in order to protect the organism. For example dinoflagellates flash their light during night or dark cycles to distract predators and reveal their predator to higher predators (Akilesh, 2000). Another example is the cookie-cutter shark, whose belly lights up, and is covered during the day by another organ. When the shark swims up in the waters its neck does not have the bioluminescence and so it appears to be a small fish and when bigger predators get close it attacks (Akilesh, 2000). Bioluminescence is seen more in aquatic organisms, probably because it is more beneficial to them in the mercy waters. This paper talked about the different phylum from protists all the way to vertebrates. Protists being unicellular and having no nervous system still had the ability to respond to many different kinds of environmental stimuli. Sponges have no symmetry and they are also able to respond to environmental stimuli, although usually larvae respond to more. Cnidarians have radial symmetry and therefore a corresponding nerve net, which helps them respond to environmental stimuli. Platelyhelminthes are the first to have bilateral symmetry and to go along with that their nervous system extends the length of its body, with centralization in the head, or anterior end. They also have to ganglia at the end of each nerve cord and the nerve cords are connected to allow both sides of the body to move together. The mollusks have a wide range of diversity in their nervous systems, ranging from nerve nets to highly cephalized cephalopods. The segmentation of annelids and arthropods allows each segment to be controlled individually but the nerve cord still runs through each segment. The vertebrates have the most evolved nervous system. This is because they have the ability to respond to stimuli, hold memory, learn, and think. This means that we dont have to come in contact with everything in the environment to understand it. The more complex a body plan becomes the more complex the corresponding nervous system becomes as well. A simple body plan doesnt have the room to house a huge brain, and therefore simple or no nervous systems are seen. Literature Cited Akilesh, S. (2000). Bioluminescence: Natures Bright Idea.

Communication and Culture Essay -- Philosophy, Taoism
Scholars from the indigenous psychology and philosophy field noted that explanations of the differences between the East and West, such as individualism/collectivism, have relied most exclusively on theoretical constructs generated in Western cultural contexts (Cheng, 1987; Cushman & Kincaid, 1987; Peng, Spencer-Rodgers, & Nian, 2006). Peng and his colleagues argued that indigenous concepts need to be introduced into the mainstream study, and the cultural differences between Western and Eastern people in the domains of thinking and reasoning can be attributed to differences between Western and Eastern folk epistemologies (Peng et al., 2006). Moreover, communication theory can be explored from both Western and Eastern perspectives by bringing in philosophical thoughts (Cushman & Kincaid, 1987). With its rich background and insights into human nature and human understanding, philosophy can make contributions to contemporary communication theory by recognizing the crucial nece ssity of the human context for communication (Cushman & Kincaid, 1987). Cheng (1987) noted that by bringing in philosophical perspective, the way of communication can be understood in a much broader sense. For instance, when comparing the differences between the West and China, scholars pointed out that while Chinese thinking and reasoning are mainly guided by folk version of Taoism and Chââ¬â¢an Buddhism, Western thinking and reasoning are mostly Aristotelian in spirit (Cheng, 1987; Peng et al., 2006). The theoretical foundation of Taoism belief is the idea that two opposites are mutually dependent on each other (Peng et al., 2006). This mutual dependence can be found between form and substance, between knowledge and action, and between symbol and e... ...ive emphasizes selflessness and submission to central authority as the institutional means for achieving unity and harmony between man, and nature and this is the principle goal for communication. In contrast, the Western perspective emphasizes self-cultivation and the subjugation of human and natural resources to individual control as the central means for achieving individual and group goal attainment. According to the Eastern perspective, an individual's participation in a collective institutional structure motivates human action and human communication, therefore, serves for the need of participation (Cushman & Kincaid, 2006). According the Western perspective, an individual's desire for political, social, and economic self-realization actuates human action and human communication, therefore, serves for the need of self-realization (Cushman & Kincaid, 2006).

The Human Genome Project Essay -- Science Genetics Essays
The Human Genome Project On the brink of the 21st century, genetics is paving the way into a brave, new world where the discoveries being made will bestow upon us tremendous powers and possibilities that are restricted only by our imaginations. Many things long considered "science fiction" are well on their way to becoming reality. Advancements made by the Human Genome Project give us the ability to alter our own destinies along with those of our descendents. However, along with the benefits of increased control over our lives come the uncertainties: Will humankind choose to draw boundaries in regards to genetic choices? Where will those boundaries be? How will this affect our future? Could our deepened knowledge of the power of genetics threaten the biodiversity essential to evolution? Would we, in essence, be "playing God"? One thing is certain- life, as we know it, will never be the same (Rayl, 112). Before one can speculate intellectually about the benefits and uncertainties of genetic study, it is important to understand how we, as humankind, have reached this breaking point of science. The HGP began in 1990 as a 15-year project coordinated by the U.S. Department of Energy and the National Institutes of Health. It is expected to be complete by 2003, two years ahead of schedule, due to rapid technological advances. The overall goals of this project are to catalog the estimated 80,000- 100,000 genes in the human DNA and to determine the sequences of the 3 billion chemical bases that make up the human DNA. This new information will then be stored in databases, as geneticists then develop tools for its analysis. Finally, the HGP is to address the ethical, legal, and social issues that may arise from the genetic research (... ...ty, must agree upon a set of rules and standards that will govern the ethical, legal, and social issues surrounding the final outcome of the project.

Lord Capulet in William Shakespeares Romeo and Juliet :: Romeo and Juliet Essays
In the play Romeo and Juliet by William Shakespeare Lord Capulet is a very prominent character. He is wealthy and a leader in his community. He is a very loving father to his daughter Juliet, he is a very contradictory person, and he trusts everyone to do as they are told and to act appropriately. Lord Capulet is a loving father who deeply cares for Juliet. When he arranges the marriage between her and Paris, he is just trying to do what he feels is best for her. He knows Paris, being handsome and rich, will make a good husband to Juliet. When she refuses to marry Paris he goes into a violent rage, saying things he doesnââ¬â¢t mean. ââ¬Å"Hang thee, young baggage, disobedient wretch! / I tell thee what: get thee to church oââ¬â¢Thursday, / Or never after look me in the face.â⬠(3.5.166-168). He feels that the marriage of the two will be beneficial for Juliet and he loves her so much that he doesnââ¬â¢t mean to hurt her feelings. When Juliet ââ¬Å"diesâ⬠he laments. ââ¬Å"Despised, distressed, hated, martyred, killed! / Uncomfortable time, why camââ¬â¢st thou now/ To murder, murder our solemnity? / O child! O child! My soul and not my child! / Dead art thou! Alack, my child is dead, / And with my child my joys are buried.â⬠(4.5.65-70). He cries out in a pain and anguish for his lost daughter Juliet. By showing emotion on account of her death and for her disobedience, Capulet shows that he really does care for Juliet and that he is a good father, wanting the best for her. Lord Capulet is a very trusting. He trusts Paris with his daughter, knowing that he would be a good husband to her. ââ¬Å"Sir Paris, I will make a desperate tender / Of my childââ¬â¢s love. I think she will be ruled / In all respects by me. Nay, more, I doubt it not-ââ¬Å" (3.5.13-15). He believes that Paris will keep his word and love Juliet. After the death of Tybalt, he is sorrowful, and I think that is one of the reasons he trusts that Juliet will agree with this marriage. When Romeo, at the beginning of the play, shows up at the Capulet party, Tybalt is angered. He tells Capulet that he would kill Romeo if he had his permission. Even though Romeo was of the Montague family, he still trusted him not to do anything bad at the party.

Torture and Ethics
Torture and Ethics Bradley Sexton April 13, 2013 University of Phoenix AJS 512 Dr. Miron Gilbert Torture and Ethics The torturing of human life always has been and always will be unethical, immoral, unjust, and wrong. Torturing enemy combatants or high-value targets does violate standards of morality in the free world. In addition to violating international laws against such practices, torture violates every basic human right. Torture is a form of cruel and unusual punishment by any standard regardless of the end result.Torture of one individual is only justifiable by saving the lives of the many, but that does not make it moral or right. The only ethical theory that justifies torture as moral acceptable is the utilitarianism view. This view should remain in the dark ages where it belongs because it is not an example of the moral standards that exit today. For some people, the thought of torturing one person to save the lives of many sounds like the right idea. The problem with tortu re is the end result is not guaranteed. Under extreme measures people will say whatever it takes to stop the pain.Torturing lowers the moral standards of the people performing the act to the same standards they are fighting against. In the long run this only fuels the enemy's commitment to their cause and makes them stronger. An enemy combatant who is considering volunteering information will not come forward if he or she thinks there is a possibility of torture on the other side. Although it is true that other countries have already used torture on American people, future prisoners of war may receive even worse treatment if the enemy knows their prisoners are undergoing torture.The use of cruel and unusual punishment during interrogation violates human rights and makes any evidence obtained unusable in a court of law. The government and the criminal justice system must observe and follow the same laws they expect society to follow. Laws apply to everyone equally in American society (Evans, 2007). Reasoning, deceiving, and bribing the suspect with rewards will produce more accurate results than torture. The victim of torture under a state of duress and pain may not even think clearly enough to speak the truth.He or she might even think their own lies are truth. Often only the threat of torture against the suspect or their family is enough to convince them to cooperate. The technology available in the modern world makes torture obsolete and unnecessary. The government can easily put together enough proof to make the suspect think he or she is about to undergo torture, or think someone they care about is in custody. Police agencies use deceitful tactics all the time to cause a suspect to make mistakes or tell the truth without resorting to immoral or unethical acts of violence.The results prove to be more accurate than torture and do no harm to the suspect. Considering torture only as a last resort after all other attempts fail is up to the people in charge of t he interrogation in compliance with the law. Regardless of the outcome the actual act of torture is always morally and ethically wrong. Ontological View Torture is not justified under the ontological theory of ethics because it is wrong to cause harm regardless of the consequences. Freewill allows people to make their own decisions about right and wrong and sharing of information.Forcing people against their will to tell the truth or lie is morally wrong under the ontological view. Although even under this view, knowing it is wrong to do so will not stop some people from torturing another if the ends justify the means in their eyes. A father may well be within his right to torture the suspect who kidnapped his child. This does not make the act morally or ethically right for the father but may lead to the safe recovery of his offspring. Society would not hold anything against such an act under the circumstances (Himma, 2009). Deontological ViewTorture is not justified under the deont ological view because the consequences of the actions do not matter. Society considers torture ethically and morally wrong so the deontological view of torture is also wrong regardless of end result. Deontological ethics state that people should always follow their obligations and duty to society. In the case of torture a person's duty and obligation is to uphold the rights of the suspect. Even if the end result saves the lives of thousands of other people torture is still unethical and immoral. This does not stop many governments from performing the act of torture.In any given situation in which many lives are at stake a government will resort to anything that reduces the risks and saves the lives of the many. When human life is at stake, morality, and ethics tend to take a back seat to humanity for all (Souryal, 2007). Utilitarianism View Torture is justified under the utilitarianism view because pleasure for the majority outweighs the pain of the few. Utilitarianism sees pleasure for the most people as justice regardless of the pain this may cause a few people. Torturing enemy combatants and high value targets does not violate standards of morality under the utilitarianism view.Whether this act violates basic human rights is not a concern for utilitarianism as long as it results in happiness for the majority. The problem with this view is that it opens the door to other immoral acts. If torture continues until the suspect is dead without gaining any knowledge that could provide happiness, then the act is immoral. Many innocent people could face torture leading to no results and utilitarianism becomes immoral. Under this justification using humans as guinea pigs for the happiness of the majority is also moral.Causing cruel and unusual punishment for prisoners is moral if the acts deter future crimes. Genocide is moral if the minority population is interfering with the happiness of the majority (Driver, 2009). Natural Law View Torture is not justified under n atural law because the basis of right and wrong is on the act itself not the results. Causing harm to another human for any reason is immoral and wrong under natural law. Humans have moral standards that prevent them from acting like animals in that they do not harm another person to survive. The strongest find another way to survive without harming others.Humans help their fellow man live rather than taking advantage of them. Everyone has equal rights to freedom from persecution in any manner. Even the worst criminals who are guilty beyond a reasonable doubt are free from cruel and unusual punishment. Although this right is granted in the United States Constitution, it began as a natural law. Under natural law the use of any type of physical or mental pain to seek information or the truth is a form of torture and is ethically wrong. Although society may agree with harsh sentences for prisoners, they do not cross the line to unusual punishment (PSU, 2007).Conclusion Even during time s of war against another country the standards of morality in America should not to heed to same immoral acts the enemy has. The moral and ethical standards in America are higher than anywhere else in the world. Torture of any type is never a good idea and rarely produces effects great enough for the ends to justify the means. Any country that condones torture of their enemies eventually will use torture against their own citizens if it fits their agenda. Out of four ethical theories only utilitarianism views the act of torture as justice.In America the utilitarianism view is not the normal view of society in general. Torturing enemy combatants or high value targets does violate the standards of morality in America. Torturing should never be given legal status as there are always other options to choose from that do not violate human rights, ethics, or morality.

Nightmare
ââ¬Å"Do not forget to wash your legs before going to bed! â⬠my mother used to tell me almost every night if I were at home. Noon might get a nightmare. â⬠I never believed her until it happened to me. It was on a night at my hostel Sole Slash, when all of my housemates were going back home as It was a three-day weekend. Since my house was In Pang and it took about 4 hours to get there, I decided to stay here alone. Moreover, there were tons of assignments need to be done. I was preparing the slides for my book review presentation when all of sudden there was a blackout and It was totally dark.Only God knew how I felt on that particular moment. Thank God, It was only for only about 15 minutes. I continued finishing my slides then. I kept on doing my assignment without bothering to look at the clock. Finally, I feel very contented as the slides had done beautifully and creatively by me. I wanted to do other assignments but when I glanced at the clock, It was already three In the morning! I realized that I was really exhausted and my eyes needed some rest after hours staring at the laptop screen. I turned off the laptop and went straight into my darkened room without brushing teeth and washing legs.With the help of the dim light from the street lamp nearby my room, I saw a figure sleeping on my bed. As I got nearer, the figure suddenly threw away the blanket, got up and stared at me. It was an old woman with shiny gold teeth. She raised her claw-like fingers and walked towards me. I ran to the outside where there was a badminton court. My surroundings were slowly starting to melt: the trees, the hostel blocks around me, the sky and the pathway to a garage. It seemed that I was about to dissipate as well, becoming a puddle of glue-like substance left on the ground. I noticed the creepy old woman was already behind me.I wanted to run but was unable to. I tried to scream but found that I could not. In horror I struggled and struggled to get away from the frightful woman. She dragged me to a creepy room and I was tied on a bed that looked like similarly my bed. She then went outside of the room and sang, sang, sang continuously. Soon I drifted off into a troubled sleep. I kept hearing the woman's voice even in my sleep. The next moment I gave a muffled yell and found myself panting on my bed. I heard someone was singing happily and when I went to take a look, it was Sarah who was doing her assignment on my study desk.My goodness, what a horrible nightmare it was! Sarah wished me good morning and told me that I slept with the door unlocked so she went In and found that I was still sleeping. ââ¬Å"You look so pale. Are you okay? â⬠she asked me. For a minute or so I lay on the sofa not daring to close my eyes for fear of falling asleep again and continuing the nightmare. Then I sat up on my bed until the horrible feeling passed. From then on I never went to sleep without washing my legs. Nightmare By Sylvania almost every night if I were at home.
