This essay offers a start on sorting out the relationships of argumentation and persuasion by identifying two systematic ways in which definitions of argumentation differ, namely, their descriptions of the ends and of the means involved in argumentative discourse. Against that backdrop, the traditional “conviction-persuasion” distinction is reassessed. The essay argues that the traditional distinction correctly recognizes the difference between the end of influencing attitudes and that of influencing behavior—but that it misanalyzes the means of achieving the latter (by focusing (...) on emotional arousal) and that it mistakenly contrasts “rational” and “emotional” means of influence. The larger conclusion is that understanding the relationships of the phenomena of argumentation and persuasion will require close attention to characterizations of communicative ends and means.

This article approaches the relationship of normative argumentation studies and descriptive persuasion effects research by pointing to several empirical findings that raise questions or puzzles about normatively-proper argumentative conduct. These findings indicate some complications in the analysis of normatively desirable argumentative conduct – including some ways in which practical persuasive success may not be entirely compatible with normatively-desirable advocacy practices.

Despite historic efforts to enact the Patient Protection and Affordable Care Act in 2010, national health reform is threatened by multiple legal challenges grounded in constitutional law. Premier among these claims is the premise that PPACA’s “individual mandate” is constitutionally infirm. Attorneys General in Virginia and Florida allege that Congress’ interstate commerce powers do not authorize federal imposition of the individual mandate because Congress lacks the power to regulate commercial “inactivity.” Stated simply, Congress cannot regulate individuals who choose not to (...) obtain health insurance because they are not engaged in a commercial venture. Several courts initially considering this argument have rejected it, but two federal district courts in Virginia and Florida have concurred, leading to numerous appeals and the near promise of United States Supreme Court review.

To characterize human emotions, researchers have increasingly utilized Automatic Facial Expression Analysis (AFEA), which automates the Facial Action Coding System (FACS) and translates the facial muscular positioning into the basic universal emotions. There is broad interest in the application of FACS for assessing consumer expressions as an indication of emotions to consumer product-stimuli. However, the translation of FACS to characterization of emotions is elusive in the literature. The aim of this systematic review is to give an overview of how FACS (...) has been used to investigate human emotional behavior to consumer product-based stimuli. The search was limited to studies published in English after 1978, conducted on humans, using FACS or its action units to investigate affect, where emotional response is elicited by consumer product-based stimuli evoking at least one of the five senses. The search resulted in an initial total of 1,935 records, of which 55 studies were extracted and categorized based on the outcomes of interest including (i) method of FACS implementation; (ii) purpose of study; (iii) consumer product-based stimuli used; and (iv) measures of affect validation. Most studies implemented FACS manually (73%) to develop products and/or software (20%) and used consumer product-based stimuli that had known and/or defined capacity to evoke a particular affective response, such as films and/or movie clips (20%); minimal attention was paid to consumer products with low levels of emotional competence or with unknown affective impact. The vast majority of studies (53%) did not validate FACS-determined affect and, of the validation measures that were used, most tended to be discontinuous in nature and only captured affect as it holistically related to an experience. This review illuminated some inconsistencies in how FACS is carried out as well as how emotional response is inferred from facial muscle activation. This may prompt researchers to consider measuring the total consumer experience by employing a variety of methodologies in addition to FACS and its emotion-based interpretation guide. Such strategies may better conceptualize consumers' experience with products of low, unknown, and/or undefined capacity to evoke an affective response such as product prototypes, line extensions, etc. (shrink)

This paper uses Perrow’s sociological framework as a basis for a comparative organisation analysis of the impact of expert systems on organisational issues. The study analyses the relative impact of expert systems on two different types of accounting work: auditing and tax. The results indicate an impact on factors that ultimately improve productivity. The aggregate results indicate that expert systems are found to allow the user substantial control of search for solutions and discretion on whether to follow system recommendations, increased (...) access to top management, and a decrease in the need for supervision. The systems allow the user the ability to solve a broader range of problems, while allowing the user the ability to perform more work. The comparison of auditing and tax expert systems indicates that audit systems seem to allow for greater control over search. Tax systems seem to allow more work to be done without supervision, make more decisions immediately, and allow the user to make a wider range of decisions. (shrink)

Theories of spatial cognition are derived from many sources. Psychologists are concerned with determining the features of the mind which, in combination with external inputs, produce our spatialized experience. A review of philosophical and other approaches has convinced us that the brain must come equipped to impose a three-dimensional Euclidean framework on experience – our analysis suggests that object re-identification may require such a framework. We identify this absolute, nonegocentric, spatial framework with a specific neural system centered in the hippocampus.A (...) consideration of the kinds of behaviours in which such a spatial mapping system would be important is followed by an analysis of the anatomy and physiology of this system, with special emphasis on the place-coded neurons recorded in the hippocampus of freely moving rats. A tentative physiological model for the hippocampal cognitive map is proposed. A review of lesion studies, in tasks as diverse as discrimination learning, avoidance, and extinction, shows that the cognitive map notion can adequately explain much of the data.The model is extended to humans by the assumption that spatial maps are built in one hemisphere, semantic maps in the other. The latter provide a semantic deep structure within which discourse comprehension and production can be achieved. Evidence from the study of amnesic patients, briefly reviewed, is consistent with this extension. (shrink)

Encyclopedia entry on Epicurus' theology. It considers the negative side of Epicurean theology and its basis in their physics, the Epicureans’ positive view of the nature of the gods and how they use it to critique popular religion, and the psychological benefits that they claim result from having correct views about the gods.

This introduction to Epicureanism offers students and general readers a clear exposition of the central tenets of Epicurean philosophy, one of the dominant schools of the Hellenistic period. Founded by Epicurus of Samos (c. 341–270 BCE), it held that for a human being the greatest good was to attain tranquility, free from fear and bodily pain, by seeking to understand the workings of the world and the limits of our desires. Tim O’Keefe provides an extended exegesis of the arguments that (...) support Epicurean philosophical positions, analyzing both their strengths and their weaknesses while showing how the different areas of Epicurean inquiry come together to make a whole. (shrink)

In this book, Tim O'Keefe reconstructs the theory of freedom of the ancient Greek philosopher Epicurus (341-271/0 BCE). Epicurus' theory has attracted much interest, but our attempts to understand it have been hampered by reading it anachronistically as the discovery of the modern problem of free will and determinism. O'Keefe argues that the sort of freedom which Epicurus wanted to preserve is significantly different from the 'free will' which philosophers debate today, and that in its emphasis on rational (...) action it has much closer affinities with Aristotle's thought than with current preoccupations. His original and provocative book will be of interest to a wide range of readers in Hellenistic philosophy. (shrink)

A fairly long (~15,000 word) overview of ancient theories of freedom and determinism. It covers the supposed threat of causal determinism to "free will," i.e., the sort of control we need to have in order to be rightly held responsible for our actions. But it also discusses fatalistic arguments that proceed from the Principle of Bivalence, what responsibility we have for our own characters, and god and fate. Philosophers discussed include Aristotle, Epicurus, the Stoics, Carneades, Alexander of Aphrodisias, and Plotinus. (...) Plato is mentioned in passing a few times in connection with other philosophers. (shrink)

Anaxarchus accompanied Pyrrho on Alexander the Great’s expedition to India and was known as “the Happy Man” because of his impassivity and contentment. Our sources on his philosophy are limited and largely consist of anecdotes about his interactions with Pyrrho and Alexander, but they allow us to reconstruct a distinctive ethical position. It overlaps with several disparate ethical traditions but is not merely a hodge-podge; it hangs together as a unified whole. Like Pyrrho, he asserts that things are indifferent in (...) value and that realizing this indifference leads to contentment. But this doctrine of indifference is rooted in Democritean atomism. And in his pursuit of pleasure and dismissiveness of conventional standards of what is just, noble, and pious, Anaxarchus is closer to fifth century thinkers such as Aristippus, Antiphon, and Critias.

The Cyrenaics assert that (1) particular pleasure is the highest good, and happiness is valued not for its own sake, but only for the sake of the particular pleasures that compose it; (2) we should not forego present pleasures for the sake of obtaining greater pleasure in the future. Their anti-eudaimonism and lack of future-concern do not follow from their hedonism. So why do they assert (1) and (2)? After reviewing and criticizing the proposals put forward by Annas, Irwin and (...) Tsouna, I offer two possible reconstructions. In the first reconstruction, I explain claim (1) as follows: happiness has no value above and beyond the value of the particular pleasures that compose it. Also, there is no "structure" to happiness. The Cyrenaics are targeting the thesis that happiness involves having the activities of one's life forming an organized whole, the value of which cannot be reduced to the value of the experiences within that life. I explain claim (2) as follows: a maximally pleasant life is valuable, but the best way to achieve it is to concentrate heedlessly on the present. In the second reconstruction, the good is radically relativized to one's present preferences. The Cyrenaics assert that we desire some particular pleasure, e.g., the pleasure that results from having this drink now. Thus, our telos -- which is based upon our desires -- is this particular pleasure, not (generic) 'pleasure' or the maximization of pleasure over our lifetime. As our desires change, so does our telos. I conclude that the scanty texts we have do not allow us to decide conclusively between these reconstructions, but I give some reasons to support the second over the first. (shrink)

Appeals to nature are ubiquitous in Epicurean ethics and politics. The foundation of Epicurean ethics is its claim that pleasure is the sole intrinsic good and pain the sole intrinsic evil, and this is supposedly shown by the behavior of infants who have not yet been corrupted, "when nature's judgement is pure and whole." Central to their recommendations about how to attain pleasure is their division between types of desires: the natural and necessary ones, the natural but non-necessary ones, and (...) the vain and empty ones. Elsewhere, the Epicureans talk about the "natural goods" of political power and fame, and they contrast "natural wealth" with wealth as "defined by empty opinion." Finally, in their politics, Epicurus claims that the "the justice of nature is a pledge of reciprocal usefulness, [i.e.,] neither to harm one another nor to be harmed." This paper explores two questions regarding these various appeals to nature. The first is: what is it for these things to be natural, i.e., what notion of "natural" or "nature" is at play here? (Furthermore, is there a single notion being used across these appeals, and if not, how are they related?) The second is: what normative work does a thing's being natural do? That is, what reason, if any, does a desire's being natural give me for pursuing the object of that desire and trying to fulfill that desire, as opposed to not doing so and trying to eliminate it, and similarly for the other appeals to nature?

Epicurus thought that the conventional values of Greek society—in particular, its celebration of luxury and wealth—often led people astray. It is by rejecting these values, reducing our desires, and leading a moderately ascetic life that we can attain happiness. But Epicurus’ message is also pertinent for those of us in modern Western culture, with an economy based on constant consumption and an advertising industry that molds us to serve that economy by enlarging our desires. This paper begins with an outline (...) of some of the basic tenets of Epicurean ethics, followed by an explanation of how these tenets lead to an Epicurean diagnosis of what ails modern consumers and of the cure they would propose. The paper closes with a consideration of recent psychological research in well-being and how it supports the Epicurean position. (shrink)

What is distinctive about Lucretius’s version of Epicureanism? The answer might appear to be “nothing,” for two reasons. First, Epicureanism in general is doctrinally conservative, with followers of Epicurus claiming to follow his authority. Second, Lucretius claims to be merely transmitting the arguments of his beloved master Epicurus in a pleasing manner. I argue that these considerations do not prevent De Rerum Natura from presenting a distinct version of Epicureanism. Its arguments in physics are almost certainly drawn from Epicurus himself. (...) But in the examples Lucretius uses to illustrate these arguments, as well as in his descriptions of things like the fear of death and the formation of society, Lucretius delivers unexpected insights into human psychology, ones not clearly present in the other sources we have on Epicureanism. Furthermore, the way in which Lucretius presents his arguments can rightly be considered original philosophically and not just poetically. (shrink)

Socrates has an implicit argument for his afterlife story that concludes the Gorgias, with two key premises. One is at 527a–c, where he summarizes the ethical position he has been arguing for through most of the dialogue, regarding the intrinsic goodness of justice, the intrinsic badness of injustice, and the desirability of rehabilitative punishments. The second occurs at 507e–508a, where Socrates asserts that the universe is held together by justice. This argument explains why Socrates regards his story as a logos, (...) not merely a muthos. It also helps us understand the nature of the rewards and punishments in his story. (shrink)

Epicurus is strongly committed to psychological and ethical egoism and hedonism. However, these commitments do not square easily with many of the claims made by Epicureans about friendship: for instance, that the wise man will sometimes die for his friend, that the wise man will love his friend as much as himself, feel exactly the same toward his friend as toward himself, and exert himself as much for his friend's pleasure as for his own, and that every friendship is worth (...) choosing for its own sake. These claims have led some scholars to assert that Epicurus inconsistently affirms that friendship has an altruistic element. I argue that the Epicurean claims about friendship can be reconciled with egoism and hedonism in psychology and ethics. Friendship is valuable because having friends provides one with security more effectively than any other means, and having confidence that one will be secure in the future either is identical to ataraxia, or the grounds on which one has it.

Overview of the Stoic position. Looks at the roots of their determinism in their theology, their response to the 'lazy argument' that believing that all things are fated makes action pointless, their analysis of human action and how it allows actions to be 'up to us,' their rejection of the Principle of Alternate Possibilities, their rejection of anger and other negative reactive attitudes, and their contention that submission to god's will brings true freedom.

One striking oddity about Democritus and Epicurus is that, even though Epicurus' theory of perception is largely the same as that of Democritus, Democritus and his followers draw skeptical conclusions from this theory of perception, whereas Epicurus declares that all perceptions are true or real. I believe that the dispute between Democritus and Epicurus stems from a question over what sort of ontological status should be assigned to sensible qualities. In this paper, I address three questions: 1) Why were Democritus (...) and his followers skeptical? 2) How did Epicurus modify Democritus' metaphysics in order to avoid these skeptical conclusions? and 3) How successful was he? -/- 1) I argue that Democritus allows only the intrinsic properties of atoms into his ontology, and then runs into skeptical difficulties because of the relativity of perception. 2) I propose that Epicurus modifies Democritus' ontology by allowing dispositional and relational properties as real properties of bodies. Sensible qualities are conceptualized as dispositional properties of bodies to cause certain experiences in percipients. 3) I argue that Epicurus does not run into the same problems as Democritus. Finally, I consider how my interpretation of Epicurus' ontology helps to make sense of his claim that all perceptions are alethes--'true' or 'real.'. (shrink)

Overview of the Epicurean views on why humans are rightly held responsible for their actions. Includes a discussion of the role the atomic 'swerve' plays in preserving our freedom, bivalence, our responsibility for how our character develops, and human reason and freedom.

The first part of this paper looks into the question of Lucretius’ philosophical sources and whether he draws almost exclusively from Epicurus himself or also from later Epicurean texts. I argue that such debates are inconclusive and likely will remain so, even if additional Epicurean texts are discovered, and that even if we were able to ascertain Lucretius’ philosophical sources, doing so would add little to our understanding of the De Rerum Natura. The second part of the paper turns to (...) a consideration of what Lucretius does with his philosophical sources. The arguments within the De Rerum Natura are not original. Nonetheless, the way Lucretius presents these arguments establishes him as a distinctive philosopher. Lucretius deploys non-argumentative methods of persuasion such as appealing to emotions, redeploying powerful cultural tropes, and ridicule. These methods of persuasion do not undercut or displace reasoned argumentation. Instead, they complement it. Lucretius’ use of these methods is rooted in his understanding of human psychology, that we have been culturally conditioned to have empty desires, false beliefs, and destructive emotions, ones that are often subconscious. Effective persuasion must take into account the biases, stereotypes, and other psychological factors that hinder people from accepting Epicurus’ healing gospel. (shrink)

The 'swerve' is not supposed to provide a temporal 'starting point' (archê) of collisions, since Epicurus thinks that there is no temporal starting-point of collisions. Instead, the swerve is supposed to provide an explanatory archê of collisions. In positing the swerve, Epicurus is responding to Aristotle's criticisms of Democritus' theory of motion.

The few people familiar with the pseudo-Platonic dialogue Axiochus generally have a low opinion of it. It's easy to see why: the dialogue is a mish-mash of Platonic, Epicurean and Cynic arguments against the fear of death, seemingly tossed together with no regard whatsoever for their consistency. As Furley notes, the Axiochus appears to be horribly confused. Whereas in the Apology Socrates argues that death is either annihilation or a relocation of the soul, and is a blessing either way, "the (...) Socrates of the Axiochus wants to have it both ways": death is both annihilation and a release of the soul from the body into a better realm. This may be used to construct a valid argument for the conclusion that death is not evil, but at the expense of having a contradiction as one of its premises. But D. S. Hutchinson has recently proposed that these inconsistencies shouldn't surprise us if we view the Axiochus as "an unconventional version of a very conventional genre--the consolation letter." In this paper I expand on Hutchinson's brief suggestion and argue that the Axiochus can be rehabilitated by paying attention to its genre. Although the Axiochus does display many similarities to the consolation letter, the shift from letter to dialogue does--pace Hutchinson--significantly affect what's going on. Within the dialogue, Socrates behaves toward Axiochus in a way similar to the way the author of a consolation letter behaves towards the letter's reader: he is willing to use inconsistent arguments, borrowed from any source, in order to soothe the patient. However, in depicting this type of consolatory relationship between Socrates and Axiochus, the dialogue itself is not aiming at consoling its readers. Instead, it should be seen as displaying for the reader's consideration a certain type of consolatory argumentative practice. -/- Socrates notes that Axiochus is "very much in need of consolation" (365a), and he uses any means necessary to accomplish this task. Socrates exhibits many ways in which he is willing to sacrifice argumentative hygiene for the sake of therapeutic effectiveness. These include: -/- * Use of arguments with inconsistent premises, presented in propria persona. * Appeals to emotion * Tailoring arguments to the audience. * Presenting invalid arguments so as to induce unjustified but comforting beliefs. * Evasion. In these respects, I think that Socrates' argumentative practice is best compared to PH III 280-1, where Sextus Empiricus says that the skeptic will deliberately use logically weak arguments as long as they work. Dorothy Tarrant claims that what links the Socrates of the Axiochus to Socrates as he appears elsewhere in the Platonic corpus is his evident care for the welfare of his interlocutor's psyche. But this concern takes a quite different form in the Axiochus than it usually does. As with Sextus, psychic therapy in the Axiochus involves relief from pain. The primary difference between them is that Socrates, unlike Sextus, is not aiming at producing epochê in his patient. (shrink)

Brief article on this hedonist, follower of Socrates, and founder of the Cyrenaic school.

Overview of this minor Socratic school, including their skepticism and hedonistic ethics.

In Outlines of Pyrrhonism, Sextus Empiricus takes pains to differentiate the skeptical way of life from other positions with which it is often confused, and in the course of this discussion he briefly explains how skepticism differs from Cyrenaicism. Surprisingly, Sextus does not mention an important apparent difference between the two. The Cyrenaics have a positive epistemic commitment--that we can apprehend our own affections. Although we cannot know whether the honey is really sweet, we can know infallibly that right now (...) we are being sweetened. By contrast, Sextus says explicitly that, as skeptics, Pyrrhonists apprehend nothing whatsoever. A case can (and has) been made that Sextus does not mention this difference because, on this matter, there really isn't an important difference between the two: the skeptic is perfectly able to report how things appear to him, e.g., that the honey seems sweet, and it is crucial for the skeptic that he not abolish the appearances. But, I argue, what the skeptics are doing when they report how things appear to them is importantly different from the sort of immediate, infallible apprehension of one's own affections claimed by the Cyrenaics, as the latter involves theoretical commitments regarding the nature of one's affections that the skeptic eschews.

Unlike mainstream Cyrenaics, the Annicereans deny that friendship is chosen only because of its usefulness. Instead, the wise person cares for her friend and endures pains for him because of her goodwill and love. Nonetheless, the Annicereans maintain that your own pleasure is the telos and that a friend’s happiness isn’t intrinsically choiceworthy. Their position appears internally inconsistent or to attribute doublethink to the wise person. But we can avoid these problems. We have good textual grounds to attribute to the (...) Annicereans a doctrine of “non-hedonic habits,” which allows them to abandon psychological hedonism while still maintaining hedonism regarding well-being. (shrink)

Overview of Epicurean physics and epistemology, ending with a critical discussion of Cicero's report on Epicurean theology.

This paper focuses on two questions: (I) why do the Cyrenaics deny that we can gain knowledge concerning "external things," and (II) how wide-ranging is this denial? On the first question, I argue that the Cyrenaics are skeptical because of their contrast between the indubitable grasp we have of own affections, versus the inaccessibility of external things that cause these affections. Furthermore, this inaccessibility is due to our cognitive and perceptual limitations--it is an epistemological doctrine rooted in their psychology--and not (...) (pace Zilioli) due to any metaphysical theses regarding the external world. On the second question, I argue (pace Tsouna and Warren) that the scope of the Cyrenaics' skepticism is quite wide. Our reports on the Cyrenaics are inconsistent, but the most charitable and plausible reading results in attributing to the Cyrenaics skepticism not merely about the properties of external things (e.g., that the fire that warms me is really hot) of also of their nature and identity (e.g., that the object that warms me is a fire). However, it does not extend to skepticism regarding the existence of an external world. (shrink)

In De Rerum Natura III 963-971, Lucretius argues that death should not be feared because it is a necessary part of the natural cycle of life and death. This argument has received little philosophical attention, except by Martha Nussbaum, who asserts it is quite strong. However, Nussbaum's view is unsustainable, and I offer my own reading. I agree with Nussbaum that, as she construes it, the cycle of life argument is quite distinct from the better-known Epicurean arguments: not only does (...) it start from different premises, but it is a completely different type of argument. However, thus construed, it is deeply problematic. It relies on premises that are much more at home in Stoic than in Epicurean ethics, and Lucretius' appeal to nature in this argument contradicts what he says elsewhere in De Rerum Natura. I consider why Lucretius offers what appears to be such a flawed argument, and I propose a reading on which the cycle of life argument could be offered consistently by an Epicurean. The cycle of life argument, unlike the better-known arguments, does not attempt directly to show that death is not a bad thing. Instead, it targets certain destructive attitudes towards one's life that result in one fearing death. By helping relieve the interlocutor of these attitudes, the argument aims at reducing his fear of death. (shrink)

Epicurus' "On Nature" 25 is the key text for anti-reductionist interpretations of Epicurus' philosophy of mind. In it, Epicurus is trying to argue against those, like Democritus, who say that everything occurs 'of necessity,' and in the course of this argument, he says many things that appear to conflict with an Identity Theory of Mind and with causal determinism. In this paper, I engage in a close reading of this text in order to show that it does not contain any (...) clear statement of either a doctrine of radically emergent properties and "downwards causation" (contra David Sedley) or of the non-reducibility of the mental to the atomic (contra Julia Annas). I argue that Epicurus' main thesis is that we cannot consistently argue against our conception of ourselves as rational agents, and that it is our reason that allows us to reform our characters, control our actions, and blame and praise one another appropriately. The way that Epicurus describes the development and causal efficacy of reason in "On Nature" book 25 is consistent both with reductionism and (more surprisingly) with causal determinism. (shrink)

The Epicureans advocate a moderately ascetic lifestyle on instrumental grounds, as the most effective means to securing tranquility. The virtuous person will reduce his desires to what is natural and necessary in order to avoid the trouble and anxiety caused by excessive desire. So much is clear from Epicurus' general ethics. But the later Epicurean Philodemus fills in far more detail about the attitude a wise Epicurean will take toward wealth in his treatise On Property Management. This paper explores some (...) of Philodemus' distinctive doctrines and argues that Philodemus' position on crafts is an improvement on the Socratic and Aristotelian positions that he is reacting against. Philodemus rejects both constraints on what counts as a genuine craft proposed by Socrates in the Gorgias: that a craft aims at a genuine good, and that it is based on a grasp of the nature of its subject. Philodemus also rejects the attempts of Xenophon and Theophrastus to preserve an important place for the craft of property management, conceived of as aiming at maximizing your wealth, within the Socratic and Aristotelian ethical tradition that puts virtue and virtuous activity at the center of the happy life. According to Philodemus, cultivating and exercising the traditional technê of property management is actually incompatible with being a virtuous person and obtaining happiness. (shrink)

David Furley's work on the cosmologies of classical antiquity is structured around what he calls "two pictures of the world." The first picture, defended by both Plato and Aristotle, portrays the universe, or all that there is (to pan), as identical with our particular ordered world-system. Thus, the adherents of this view claim that the universe is finite and unique. The second system, defended by Leucippus and Democritus, portrays an infinite universe within which our particular kosmos is only one of (...) countless kosmoi. Aristotle's argument in De caelo I.9 that the world is necessarily unique is an important contribution to this debate. This argument holds interest because it shows Aristotle wrestling with an apparent inconsistency in his own philosophy, as deeply-held convictions within his cosmology collide with an equally deeply-held conviction within his metaphysics. The following three principles, each of which Aristotle appears committed to, are inconsistent: -/- The cosmic uniqueness principle. The world is necessarily unique. The cosmic form principle. The world is an ordered, structured unity. As such, the world has a form. The possibility of multiple instantiation principle. For all F, if F is a form, it is possible that there exist multiple Fs. In De caelo I.9, Aristotle argues that we can establish the uniqueness of the universe, reject the multiple instantiation principle, yet still retain the distinction between 'this world' and 'world in general,' if the following is true (as it is): the world takes up all the matter that exists. Aristotle illustrates this argument with one of the stranger analogies in his corpus: imagine an aquiline nose that takes up all the flesh in the universe. If this were so, then there could not exist any other aquiline objects whatsoever. (For this reason, we dub the De caelo I.9 argument the 'Cosmic Nose argument.') This paper is an interpretation of how this argument is supposed to proceed and an assessment of its success. The first section states the problem Aristotle is confronted with, sorts through Aristotle's various statements of the Cosmic Nose argument, which exhibit some sloppiness, and reconstructs charitably a single argument. We also spend some time examining the significance of Aristotle's example of a gigantic aquiline nose. We argue that, even charitably reconstructed, the argument appears to commit a serious modal fallacy. The remainder of the paper explores whether this modal fallacy can be overcome. We conclude that, although not a cogent argument for the uniqueness of the world (as this would require a significant revision of our current astronomy), the Cosmic Nose argument does succeed on its own terms. However, it should not be regarded as a free-standing argument for the uniqueness of the world. Instead, it depends crucially on the earlier argument in De caelo I.8 for the universe's uniqueness; De caelo I.9 should be viewed as an attempt to extend the conclusion of De caelo I.8 and to show how this conclusion can be made consistent with Aristotle's metaphysical principles about the nature of form.

Titus Lucretius Carus was an ardent disciple of Epicurus and the author of the De Rerum Natura, one of the greatest poems in Latin. Other than his approximate dates of birth and death, we have next to no reliable information about him. Because of his family name and his apparent familiarity with Roman upper-class mores, it is thought that Lucretius was probably a member of the aristocratic clan of the Lucretii, but this is not certain. And so any insight we (...) wish to gain into the thought and personality of Lucretius must come from the De Rerum Natura itself. (shrink)
