Rhetorical Devices That Will Take Your Writing from Bland to Breathtaking

Rhetorical Devices That Will Take Your Writing from Bland to Breathtaking Rhetorical devices are powerful modes of expression that writers and speakers can utilize to craft effective and persuasive pieces. Different rhetorical devices can evoke different responses, emotions, and ideas. Rhetorical devices help the audiences of writings or speeches connect with the authors and the content of what is being communicated.They are powerful in that they can be used both responsibly and irresponsibly. Because rhetorical devices have these persuasive effects, they can be used to enhance good content or conceal fallacious or poorly researched arguments. For this reason, it is important to maintain a good working knowledge of rhetorical devices. This way, in roles as either an author or an audience member, you can distinguish between responsible and irresponsible uses of rhetorical devices. Additionally, being able to evaluate the effectiveness or ineffectiveness of an authors use of rhetorical devices is a useful ability to have in any readers toolbox for critiquing others writing.The difference between rhetorical devices and figures of speechRhetorical devices are different from figures of speech in that they are primarily used to influence the audience and emphasize ideas already present in what is being communicated. Figures of speech, on the other hand, alter the meaning of the content or can contain different or additional meaning than the literal interpretation of the utterance may contain.Metaphors are an archetypal form of figures of speech. Take, for example, the metaphor that person is a beast. This utterance would not typically be understood by a listener or reader to literally infer that the person is an animal, as beast refers to non-human animals. The internal logic of the statement would be compromised if we were to assume that it implies the object of the utterance is both human, as is implied by person, and non-human, as is implied by beast. Instead, the audience typically understands that the utterance is not meant to be inte rpreted literally. The statement can be understood to imply a number of things: the person is cruel, or the person is powerful, or the person is ignorant, et cetera.Rhetorical devices, on the other hand, do not contain extra meaning or further implications. Rhetorical devices work on how the audience receives the information being presented to them. If used effectively, rhetorical devices can sway the audience towards the authors perspective. A good example of this persuasive power is one of the most basic rhetorical devices that exist: pathos.Suppose that someone is making an argument for why people should be provided with free healthcare. Take, as an example in this argument, the statement, The boy cried every night because he knew that his mother could no longer afford the medicine that was keeping her alive. In this instance, the rhetorical device is not altering the meaning or adding information to the utterance, like a figure of speech would.The rhetorical device of pathos, or an appeal to the audiences emotions, is drawing the audiences attention to the emotional component of their idea and its impact on the lives of other people. There are not additional ways for the audience to interpret this statement; the statement is meant to be taken literally. It is a fact that the boy cried, and it is a fact that the boys mother cannot afford to buy her medication. By combining these two facts in this manner, the author employs pathos in order to appeal to the audience with the hope that this will sway their opinions towards those of the author.The boy cried every night because he knew that his mother could no longer afford the medicine that was keeping her alive is an example of the rhetoical device of pathos. Photo by Kat J on Unsplash.The fundamental rhetorical devicesâ€"Ethos, Pathos, Logos, and KairosWhile there are dozens of various rhetorical devices, we will focus in on the four fundamental uses of rhetoric. Mastering these can give any piece of communic ation you produce a persuasive and personal element that will engage your audience with interesting and memorable content.EthosEthos is the Greek word for character. The rhetorical device of ethos is intended to draw the audiences attention towards the authors trustworthiness, credibility, and/or expertise. This rhetorical device typically takes one of two forms: either an appeal to credibility or an appeal to character. A rhetorical appeal to character may consist of the author referencing their good deeds or decisions that would show their high moral caliber. A rhetorical appeal to credibility may take the form of making known the authors relevant experience and knowledge.PathosPathos is the Greek word for experience. This rhetorical device takes into account the audiences ideals and perceptions. Pathos draws attention to a disparity between what the audience expects or wants of the situation and the reality of the situation. It works to engage the empathy of the audience in an ef fort to show them that what the author is arguing for will bring about the world-situation that they view as ideal.LogosLogos is the Greek word for word. Logos turns the audiences attention towards the logical structure of and evidence provided by the content of the communication. This rhetorical device focuses on making the internal logic of the communication valid. It may consist of statements that make sense in the context of the overall message and that utilize factual evidence to support its claims.KairosKairos is the Greek word for opportunity. This rhetorical device takes into consideration the outside historical and situational context of how a message is presented. To utilize kairos, one must have an extensive knowledge about the audience and the attitudes they hold. Advertisements are often good examples of the use of kairos, as many of them exploit the popularity of contemporary trends in order to communicate their message.Using rhetorical devices responsibly versus using rhetorical devices irresponsiblyThe goal of using rhetorical devices is to make our writing or speech more engaging, persuasive, and memorable. A problem can arise, however, if we do not use these devices properly or responsibly. At times, it can be rather easy for an audience to see through the rhetorical device if it is not being used earnestly or if the content lying behind the rhetoric is not logically consistent. In these cases, the curtain drops, and what could have added a nice flourish to the piece ends up alienating the audience.It is important to acknowledge and understand the moral component of using rhetorical devices. As such, we must keep in mind that there is a responsibility inherent in their use. Of course, not all irresponsible uses of rhetorical devices have malevolent origins or consequences. It is easy, also, for the use of rhetorical devices to slip into the realm of logical fallacies. This can happen intentionally or unintentionally, but either way, it is imp ortant to be able to identify this occurrence in our own and others communications. A good example of this phenomenon is the rhetorical use of ethos.If used correctly, it can imbue the audience with a sense of trust in the author, which can greatly help in convincing the audience of the authors aims. An expert witness testifying before a jury during a trial is a good example of this. The experience and knowledge that the expert has gained from their education and professional training make them more qualified than others to speak about certain subjects. The jury is expected to trust the experts opinions on the grounds that they know more about the subject.An expert witness testifying before a jury during a trial is a good example of the rhetorical device of ethos. Photo by Wesley Tingey on Unsplash.Or similarly, one may say, My experience as a teacher has proven to me that students are more likely to achieve success when they are personally invested in their own education. In this c ase, the personal experience of the speaker is given as the evidence that they have a particular expertise in the subject at hand; and while their opinion is not immune to criticism, it should be considered as more likely to be accurate than a non-experts opinion.If used incorrectly, it can backfire and lead to the audience being less likely to be persuaded by the author. Take, for example, the classic four out of five dentists recommend this toothpaste advertising cliché. This may seem like a legitimate use of ethos, and under certain circumstances, it can be. However, if we evaluate the advertisement in itself, the author (the creator/s of the advertisement) is falling prey to the logical fallacy of appeal to authority, or argument from authority. This logical fallacy occurs when an argument is supported primarily by the assertion that an authority figure endorses the argument rather than basing the argument on the logical presentation of factual evidence.In our toothpaste exampl e, we are not given any factual evidence for why this toothpaste is better than others; we are simply told that authority figures endorse it, and so we should too. So, it is first and foremost important to have a logically formulated argument based on true evidence before we ever begin to think about incorporating rhetorical devices.

The Value of Life Essay - 1133 Words

Should people put the value of life into monetary value or should life be kept solely as an emotional quantity? People and societies throughout the ages have been trying to answer the problem of putting the value of life into terms of dollar bills. The ancient Egyptians buried their dead with all of their worldly belongings. They believed a person’s monetary worth on Earth was over, and they should take all of that earthly worth with them to the afterlife. Modern day Americans are different from the Egyptians. Today people believe that the families of the dead should be compensated for â€Å"their† loss. It is true that life is a precious commodity much like a diamond. But unlike a diamond, life has no set monetary value. But today’s†¦show more content†¦Is it more important in society to â€Å"make babies† than it is to just live your life? What about people who haven’t yet had a chance to start a family because their lives were cut so short? Now all that money sounds like a blessing, doesn’t it? Well now that you have your foundation money, now you have to subtract the money you get from life insurance, pension, Social Security death benefits, and worker’s compensation. After these â€Å"little† subtractions, you now have the total that you are going to receive from the government’s fund. Now you are going to be hit with new questions after all this, for example is a rich man with high life insurance, high pension, and no children worth less than a poor man with no life insurance, no job, and ten children (Ripley 13)? The answer to all these questions is no. The lives of all people should be valued at the same price, if you are to set a price at all. A rich man should be the same as a poor man; a woman with no children should have the same life value as a woman with seven kids. The point is that if the government is going to put a monetary value of a human life, than it should be the same for everyone. â€Å"We hold these truths to self-evidence: that a ll men are created equal† (King Jr.).

Surface tenseness rises as country gets bigger and falls as country gets smaller. Physiological importance of wetting agent Additions lung conformity because surface forces are reduced. Promotes alveolar stableness and prevents alveolar prostration. Decreased surface country lowers surface tenseness. Increased surface country additions surface tenseness. Small air sacs are prevented from acquiring smaller. Large air sacs are prevented from acquiring bigger. Promotes dry air sac. Alveolar prostration tends to â€Å" suck † fluid from pneumonic capillaries. Stabilizing air sac ( see B ) prevents transudate of fluid by forestalling prostration. Infant respiratory disease syndrome ( IRDS ) Surfactant ( DPPC ) production starts tardily in foetal life so premature babies are frequently unable to do surfactant properly. Babies with unnatural wetting agent have stiff, fluid-filled lungs with atelectatic countries ( alveolar prostration ) . Non-ventilated, collapsed air sac efficaciously do right to go forth shunting of blood. [ lecithin ] / [ sphingomyelin ] ratio can be analyzed in amnionic fluid to supply an index of gestational adulthood of surfactant production. Sphingomyelin production starts early and remains changeless during gestation and is therefore a marker of entire phospholipid concentration. Sphingomyelin has no surface active belongingss. Regional lung volume and regional airing Dependent lung-the lung in the lowest portion of the gravitative field, i.e. , the base when in the unsloped place ; the dorsal part when supine. Intrapleural force per unit area is higher ( i.e. , less negative ) around dependent parts of the lung because of the weight of the lung. Figure 5 Transpulmonary force per unit area ( PALV – PPl ) is greater at the vertex ( 0- ( -10 ) than at base ( 0- ( -2.5 ) in unsloped lung. Therefore, the vertex is more hyperbolic ( i.e. , has a higher volume ) at FRC. Ventilation is greater at the base than the vertex of the unsloped lung because the base is on a steeper part of the force per unit area volume curve. The vertex is on a flatter ( less compliant ) part. The base starts with less air but has greater airing ; the vertex starts with more air volume but has less airing. Summary. Ventilation is greater in dependent parts of a normal topic ‘s lungs. Time invariables for emptying. Important regional inhomogeneities in airing can besides be caused by factors which cause regional differences in airway oppositions or elastic features. High opposition and high conformity equal slow voidance. Specific conformity. Conformity divided by resting lung volume clinically FRC is used ) . This standardization must be done to analyze the elastic features of tissue and their alterations in disease. How would compliance differ in a kid and an grownup, both with normal lungs? INTERACTIONS BETWEEN LUNGS AND CHEST WALL The lungs and chest wall operate in series and their conformities add in return to do entire conformity. The chest wall is like a spring which may be either compressed or distended. Figure 6 Transthoracic force per unit area is negative at RV and FRC intending the chest wall is smaller than its unstressed volume and its care to spring out. Normal tidal external respiration is wholly in the negative force per unit area scope. Transthoracic force per unit area is 0 at approximately 65 % of TLC intending the thorax is at its unstressed volume and has no inclination to prostration or expand. Transthoracic force per unit area is positive at volumes above approximately 65 % TLC. The chest tends to fall in above its unstressed volume. The lungs are like a spring which may merely be distended. Figure 7 The lungs are above their unstressed volume ( minimum volume ) even when the system is at residuary volume. The lungs still have some volume at their minimum volume. Transpulmonary force per unit area is positive from residuary volume to entire lung capacity so the lungs ever tend to prostration. Functional residuary capacity is the lung volume at which the inclination for the chest wall to jump outward is merely balanced by the inclination for the lungs to flinch inward. The transmural respiratory system force per unit area ( PRS = RALV – Pbs ) is zero at FRC if respiratory musculuss are relaxed. The secret plan of lung volume against transmural respiratory system force per unit area ( PRS = RALV – Pbs ) with represents the combined consequence of lung and chest wall kick. Figure 8 A pneumothorax causes lungs and chest wall to alter volume along their curve until their transmural force per unit area is zero. The lungs ever recoil inward. The chest wall springs outward unless it is inflated to beyond 65 % TLC in which instance it besides will flinch inward. Conformity alterations in disease Lungs become slightly more compliant with natural aging and go markedly more compliant with emphysema. Lungs become less compliant ( stiffer ) with pneumonic fibrosis or during hydropss caused by arthritic bosom disease. Chestwall becomes less compliant ( stiffer ) in status where the chest wall is deformed ( eg. kyphoscoliosis ) . It besides becomes functionally less compliant when abdominal pit alterations cause upward supplanting of the stop ( eg. gestation ) . AIRWAY RESISTANCE Air flow is chiefly laminal during quiet external respiration. Resistance is determined by Poiseuille ‘s Law and the force per unit area gradient required is relative to flux. When air flow additions, as in exercising, some turbulency and eddy flow develops in big air passages and at subdivision points. An excess force per unit area gradient proportional to flux rate squared is necessary. The major site of opposition is in the larger air passages specifically in the medium size bronchial tube. Merely approximately 20 % of entire air passage opposition is in little air passages ( less than 2 millimeter ) . Factors taking to cut down airway quality and increased airway opposition. Contraction of bronchial smooth musculus. Stimulations include: pneumogastric tone, histamine or reduced airway. is peculiarly of import for advancing homogenous airing. When it builds up in a ill ventilated part the air passages to that part tend to distend. Loss of elastic kick in lung ( i.e. , more compliant lungs ) . Radial grip on bronchial tubes usually helps keep them unfastened. Lower lung volumes are associated with less elastic kick and slower flow rates. Loss of elastic tissue in chronic clogging disease ( eg. emphysema ) lower elastic kick forces. Maximum forced termination consequences in Figure 9 – Expiratory flow-volume curves. May be plotted as volume vs. clip or flux vs. volume. Peak flow occurs early and flow falls as termination continues and lung volume lessenings. Effort independency. When the maximal flow-volume envelope is reached, flow falls with forced lung volume regardless of get downing volume or attempt. Mechanism of flow restriction at lower lung volumes during termination. Figure 10 – Collapse of the air passages during termination: The entire force per unit area in the air sac equals pleural force per unit area + the elastic force per unit area of the lungs. Flow in the air passage requires a force per unit area bead owing to the syrupy opposition of the gas. If the air flow is rapid plenty, or the airway opposition great plenty, this force per unit area bead will go equal to and so greater than the elastic force per unit area, the airway transmural force per unit area becomes zero or less and the air passages will be given to fall in. The point along the air passage where this occurs is called the â€Å" equal force per unit area point † . With a forced termination the equal force per unit area point moves closer to the air sac because as the flow rate additions so besides the syrupy force per unit area bead additions, but the elastic force per unit area remains the same. Cartilage in the big air passages helps to oppose the inclination to prostration during forced termination. Alveolar force per unit area = elastic kick force per unit area + intrapleural force per unit area. Mouth force per unit area = atmospheric force per unit area = 0. During expiration intrapleural force per unit area is positive ( greater than atmospheric ) . Equal force per unit area point ( EPP ) . Airway opposition causes a force per unit area bead from air sac to talk. At some point in the bronchial tube the force per unit area has dropped enough that it merely peers environing intrapleural force per unit area. This is the EPP. Since air passages are collapsable air flow will be relative to the difference between alveolar and EPP force per unit areas and reciprocally relative to the opposition of this section ( retrieve Starling Resistors ) . Increased attempt will do similar additions in alveolar force per unit area and force per unit area at the EPP. The force per unit area difference and therefore the flow will be unchanged. Flow restriction at assorted lung volumes during forced termination. High LUNG VOLUME MEDIUM LUNG VOLUME LOW LUNG VOLUME Figure 11 Flow restriction in chronic clogging disease ( emphysema ) . NORMAL LUNGS EMPHYSEMA Figure 12 Forced inspiration is non attempt independent because intrapleural force per unit area is negative and air passages are held unfastened.

Physician Assisted Suicide Essays (2384 words) - Euthanasia

Physician Assisted Suicide Many voters throughout the United States are taking the measure to legalize physician assisted suicide to the polls. If it is legalized, the United States will have legalized a much quicker, more humane method(as opposed to terminal sedation) of ending the suffering of terminally ill patients. The only legal process of this sort in the United States is terminal sedation, a method that can oftentimes add to a patient's problems. Although Oregon is the only state to have successfully passed such a bill for the legalization of physician assisted suicide, the pressure to confront this issue is growing along with the movement for legalization. Opponents of the Oregon bill, mostly Christian conservative groups, are planning to appeal this case to the Supreme Court in hopes of a reversal of the Oregon Supreme Court's decision. Though the emotional battle of physician assisted suicide is the prerogative of voters on both sides of the issue, the fundamental question that will have to be answe red by the Courts is whether or not the liberty observed by the due process clause of the fourteenth amendment contains a right to perform suicide, which itself includes a right to assistance in doing so. This clause states, ?No State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; Nor shall any State deprive any person of life, liberty, or property, without due process of law.? (United States Constitution, Amendment 14) Tierce, 2 In order to constitutionally create a previously unspecified ?right? the Supreme Court must conclude that such a ?right ? is either deeply rooted into the nation's history and tradition, or is fundamental to sustaining the liberty provided in the Constitution. The court should also have a very specific description of what is to be entailed within this ?right?. The difficulty in arguing for assisted suicide is that since the justification for assisted suicide is not historical or necessary for ordered liberty, the state must only prove that assisted suicide is within the perimeters of exercising what is best for the nation as a whole. The Supreme Court has earlier stated that, ?This requirement is unquestionably me here,? citing as concerns: preserving human life; preventing suicide; protecting the integrity and the ethics of the medical profession; protecting vulnerable groups from abuse, neglect, and mistakes; and preventing a start ?down the path to voluntary and perhaps even invol untary euthanasia.? (Annas, 1100) The possibility of legalization is, however, still quite probable, especially as one uses the Dutch government as an example, where physician assisted suicide is illegal but not prosecutable if executed under certain specified legal guidelines. The practice of physician assisted suicide in the Netherlands has been defined over many years of legal processes Tierce, 3 and medical ethics, beginning in 1973, when the first case against physician assisted suicide went to trial. The courts found the physician guilty of the crime, but suspended her sentence and effectively ruled out the threat of future prosecution. In many Dutch cases between 1973 and 1984 the courts established necessary conditions for not prosecuting a physician for assisting in a suicide. The patient must first make the request for euthanasia, and then repeat the request explicitly acknowledging their desire to die. The patient must also be suffering from a disease that has brought about severe physical or mental pain with no hope of recovery. The final case in 1984 resulted in the addition of a third guideline which required a physician to consult a colleague to verify the diagnosis, and to design the plan for euthanasia as to not inflict unnecessary suffering on others concerned. Nevertheless problems arose in the Netherlands concerning the legality of euthanasia. Thus in 1993 the Dutch Parliament passed measures to clarify the state of physician assisted suicide laws. Under the new law physician assisted suicide is still punishable by up to 12 years in prison, but if the established guidelines are followed, the practice is safely shielded by the legal system. The law requires that patients be euthanized in accordance with the following ?carefulness Tierce, 4 requirements.? (Russell, 781) The first requires that a request for death must be made entirely of the patient's free will and could
