Scaffolds are fundamental to many cellular signaling pathways. In this essay, a novel class of scaffolds are proposed, whose action bears striking resemblance to kinetic proofreading. Commonly, scaffold proteins are thought to work as tethers, bringing different components of a pathway together to improve the likelihood of their interaction. However, recent studies show that the cytoskeletal scaffold, anillin, supports contractile signaling by a novel, non‐tethering mechanism that controls the membrane dissociation kinetics of RhoA. More generally, such proof‐reading‐like scaffolds are distinguished (...) from tethers by a rare type of cooperativity, manifest as a super‐linear relationship between scaffold concentration and signaling efficiency. The evidence for this hypothesis is reviewed, its conceptual ramifications are considered, and research questions for the future are discussed. (shrink)

The recent COVID-19 crisis caught many by surprise. Yet some firms were better prepared to weather the downturn than others. Using a comprehensive data set that observes over 15,000 firms in 27 countries, including several developing countries, shortly before and after the pandemic, we document that pre-crisis innovation affected firm’s survival odds and performance thereafter. The results show that innovative firms are less likely to close and perform better than non-innovators during the pandemic crisis. Innovative firms are also more optimistic (...) about the future than non-innovators. Our results further indicate that firm’s adaptability mediates the relationship between innovation and survival outcomes. The study finding shows that innovative firms are more likely to introduce new products, remote work arrangements, increase delivery, pivoting, and online activities than non-innovators during the pandemic crisis.

Multiculturalism is not new concept Multiple cultures existed in Europe and Asia during the mediaeval period. The multicultural societies of Baghdad, Florence, and Venice played an essential role in the spread of knowledge and science. The knowledge transmitted from the House of Wisdom in Baghdad reached the multicultural societies of Venice and Florence. The Multiculturalism of Venice and Florence played an essential role in the emergence of the Renaissance in Europe. Multiculturalism became a crucial political concept in the 20th century (...) with the spread of democracy. In the post-World War II world, when the democratic system of governance spread as a universally accepted system of governance, the question of demand for political rights of multiculturalist groups and adjustment with the existing system arose. There was a massive increase in migration for various reasons, which also gave rise to many other political problems. Multiculturalism and migration got adequate space in Modood's political literature. He presented its socio-political analysis. In discussing the interrelationships between Multiculturalism and liberalism, the question of adjustment of many cultures in relatively less liberal systems provides an alternative perspective to understanding Multiculturalism through migration. -/- .

This paper investigates how Schleiermacher’s universal hermeneutics can be considered as a better alternative to both, German rationalist aesthetics as pioneered by Christian Wolff, and Kant’s transcendental idealism, to the extent of overcoming the problematics of rule-following. A general account of the necessity of a universal hermeneutics and its meaning from historical practices of exegeses is given. This is then followed by the account of rule-following in the tradition of both German rationalist aesthetics and Kant’s transcendental idealism with latter as (...) expounded in Kant’s Critique of Pure Reason. The investigation is comparative and descriptive. The purpose of this study is to discuss the hermeneutic possibilities in research methodologies for human sciences. (shrink)

One recent problem in philosophy of science is, “Ought a methodology be construed, not merely as an instrument of appraisal, but also as a source of advice to the practising scientist?” Imre Lakatos and John Worrall, among others, have answered the question in the negative. Alan Musgrave disagrees. In a section entitled, “Appraisals and Advice,” in [9], Musgrave attempts to give us a deductive argument in support of his claim that methodologies should be construed as giving advice. After briefly explaining (...) the plausibility of the claim, I shall present Musgrave's argument in full, and then examine each of his premises. I will try to show that his attempt to answer the above question in the affirmative raises some interesting questions, and which must be answered if his venture is to succeed. I should add, that if my objections are successful against Musgrave's attempt, it would be a Pyrrhic victory: I am neither an inductivist nor do I think that the answer to the question should be in the negative.

In Section 5 of his important paper, “Truth, Rationality, and the Growth of Knowledge,”’ Karl Popper discusses the requirements for knowledge to grow. According to Popper, a scientist often finds himself in the following problem-situation: A theory T that he has been using so far, while it can explain some facts, cannot explain others, and is falsified by still other facts. Consequently, the scientist desires to come up with a theory T‘ that will explain everything that T could and at (...) least some things that T could not, especially those facts which falsified T. Would not such a success, if we could emerge with a T’, be enough? Not so, claims Popper. Given that our aim is more and more interesting truth, “the logic of the general problem-situation” demands that T‘ satisfy other requirements as well. If these added requirements are not met, our aim of approach- ing truth would be vitiated.2 These additional requirements are three in all. First, that every new theory proposed, such as T‘, should proceed from some “simple, new, and powerful, unifying idea.” Second, that every new theory should be independently testable, and third, each such theory should pass some new, and severe, tests.3 Popper believes that the third requirement is crucial for the growth of knowledge, and he discusses it in considerable detail. My primary aim in this paper is to show that Popper’s arguments in support of his third requirement do not stand up. I shall argue that if knowledge can grow at all on Popper’s other assumptions then it can grow even if every new theory subsequent to the initial theory should violate Popper’s third requirement. In showing how knowledge can grow even though the third requirement is never satisfied, I use assumptions and methods which Popper allows himself. Hence, I leave open the question of the legitimacy of these assumptions and methods which have, in fact, been severely criticized by Adolf Grunbaum, David Miller, Pave1 Tichy, and others. (shrink)

Jensen’s inequality is one of the fundamental inequalities which has several applications in almost every field of science. In 2003, Mercer gave a variant of Jensen’s inequality which is known as Jensen–Mercer’s inequality. The purpose of this article is to propose new bounds for Csiszár and related divergences by means of Jensen–Mercer’s inequality. Also, we investigate several new bounds for Zipf–Mandelbrot entropy. The idea of this article may further stimulate research on information theory with the help of Jensen–Mercer’s inequality.

Gandhi was a political and social activist rather than a philosopher or thinker. However, the level of morality and purity in his politics was so high that it took politics to the spiritual and philosophical level. The same thing can be said for his social and economic thoughts. Therefore, Gandhi's Swaraj is cultural, political and spiritual because politics was a spiritual ( religious) work for him. The question of Swaraj was not just a political question for him, nor did Swaraj (...) mean for him only the expulsion of the British from India but freedom from slavery mentality as well . Thus, Gandhian Swaraj goes beyond the concept of political sef rule and freedom. Swaraj is one's self rule over body and soul, a comprehensive self control. Swaraj is an equally important question in post independent India too. Swaraj is a vigilance for civil rights, public welfare, constitutionalism and good governance in a politically independent country. It empowers civil society. Hence Swaraj is continuous effort of independence and insistence on truth against arbitrary power of state and thus Swaraj creates and empowers civil society. From this point of view, Locke, Mill, and Rousseau are seen together in his Swarajist thoughts. Therefore, for Gandhi, Swaraj is a continuous process . (shrink)

ā no bhadrāḥ kratavo yantu viśvato ' Let good thoughts come from all around; inspired by this timeless epic of Rigveda. India has presented an excellent model of Multiculturalism to the world. The multiculturalist model of the West, as established by contemporary thinkers like Will kymlicka, is based on the separate political existence of different cultural classes. However, India's cultural nationalism has shown how diverse cultures can co-exist with a common socio-political thought over the centuries. Sakas, Huns, Kushans, Turks, Afghan, (...) Iranians, and Mughals all got absorbed in sanatan Indian culture. Not only this , it also gave place to the different cultures to come, and made the model, of coexistence alive. In the name of nationalities like French, Spanish, Portuguese, Polish, and German, Europe got divided into many nation states, but in India Gujarati, Marathi,, Telugu Oriya, Bengali, Punjabi, Assamese, Tamil, Kannada, Malayalam nationalities were not divided into nation states. Instead coexistence has been made for thousands of years. India has maintained multiculturalism not only at the socio-cultural level but also at the political level. Through federal structure, universal suffrage, constitutionally guaranteed civil rights, with other constitutional, institutions and provisions, multiculturalism is being addressed at the political level for population of 13 million people. Thus, in India, multiculturalism is not only a political tool for diversity but also a socio-political concept. Therefore, Indian multiculturalism presents a comprehensive, effective and more sustainable model which have to be discussed. (shrink)

If we first ask about the goals Machiavelli urges us to embrace as citizens, these all turn out to be feminine: wealth, liberty, and civic greatness. If we next ask about the type of community we need to sustain in order to realize these goals, we find that this is seen by contrast as masculine: it must be a vivere politico, a vivere civile, a vivere libero--terms usually translated as a 'free state.' If we go on to ask about the (...) qualities needed to uphold such a community, these again prove to be feminine, including virtu itself as well as the attribute of prudence, the greatest of political virtues. But if we ask finally about the institutions and arrangements we need to establish in order to promote civic virtues, we find that these--the most basic and shaping elements--are entirely masculine: not merely the term for the general condition of public life (lo stato), but also the words used to describe specific institutions (including the Senate and the various magistracies) and the ordini or ordinances that bind the whole edifice together.

Derek Parfit's On What Mattersis widely recognized as elegant, profound, and destined to change the landscape of moral philosophy. In Volume One, Parfit argues that the distinct--indeed, powerfully conflicting--theories of deontology and contractualism can be woven together in a way so as to yield utilitarian conclusions. Husain Sarkar in this book calls this, The Ultimate Derivation. Sarkar argues, however, that this derivation is untenable. To underwrite this conclusion, this book traverses considerable Parfitian terrain. Sarkar shows why Parfit hasn't quite (...) solved what Sidgwick had called "the profoundest problem in ethics"; he offers a reading of Kant, Rawls, and Scanlon that reveals Parfit's keen utilitarian bias; and he demonstrates why Parfit's Triple Theorydoes not succeed in its task of unifying conflicting moral theories. The final chapter of the book is about meta-ethics. It shows that Parfit's Convergence Principleis mistaken even though it unveils Parfit's utterly humane concerns: Moral philosophers are not, as Parfit thinks, climbing the same mountain. But for all that, Sarkar maintains, Parfit's book is arguably the greatest consequential tract in the history of moral philosophy. shows that Parfit's Convergence Principleis mistaken even though it unveils Parfit's utterly humane concerns: Moral philosophers are not, as Parfit thinks, climbing the same mountain.

Within Robert Nozick's theory of Justice as presented in his Anarchy, State and Utopia, does the Lockean proviso dovetail with the theory of entitlement? The main burden of this paper is to establish that far from dovetailing, there is a serious conflict between the two.Nozick's theory of Justice consists of at least three principles, namely, the principle of Justice in acquisition, the principle of Justice in transfer, and the principle of rectification of injustice. These principles treat the topics of how (...) unheld things came to be held, how they came to be transferred, and how injustice in respect to them came to be corrected or rectified. Although Nozick does not provide a detailed philosophical picture of these principles of Justice, he says enough about each of them by way of examples and explanations to constitute a powerful, criticizable doctrine.

Jarrett Leplin in A Novel Defense of Scientific Realism (1997) argues that if the thesis of empirical equivalence is cogent, then the thesis of underdetermination cannot even get off the ground. Part of Leplin's argument rests on the claim that auxiliary hypotheses can be independently confirmed, thus enabling us to determine the epistemic worth of a theory. This, in turn, helps in determining about what we should be realists. Leplin's claims are demonstrated to be problematic. Leplin wants, inconsistently, to use (...) only those auxiliary hypotheses which dovetail with confirmed theories. Finally, a detail of Leplin's argument is found wanting. (shrink)

IN KANT’S ETHICAL THOUGHT, Allen W. Wood powerfully argues in defense of Kant’s alleged notion that we ought not to compare ourselves with others on the moral scale, however much such comparison may be meaningful and permissible with respect to our other skills and characteristics, such as the artistic, practical, or technological. Meaningful, permissible, comparable or not, those skills and characteristics have no inherent worth anyway. These have a market price or a fancy price but no dignity, and it is (...) only dignity which confers incomparable moral worth. A human being, says Kant, “possesses a dignity by which he exacts respect for himself from all other rational beings in the world. He can measure himself with every other being of this kind and value himself on a footing of equality with them.”. (shrink)

We describe a case of indeterminacy in general relativity for homogeneous and isotropic cosmologies for a class of dark energy fluids. The cosmologies are parametrized by an equation of state variable, with one instance giving the same solution as Norton’s mechanical dome. Our example goes beyond previously studied cases in that indeterminacy lies in the evolution of spacetime itself: the onset of the Big Bang is indeterminate. We show further that the indeterminacy is resolved if the dynamics is viewed relationally.

The abundance of information technology and electronic resources for academic materials has contributed to the attention given to research on plagiarism from various perspectives. Among the issues that have attracted researchers’ attention are perceptions of plagiarism and attitudes toward plagiarism. This article presents a critical review of studies that have been conducted to examine staff’s and students’ perceptions of and attitudes toward plagiarism. It also presents a review of studies that have focused on factors contributing to plagiarism. Our review of (...) studies reveals that most of the studies on perceptions of plagiarism and attitudes toward plagiarism lack an in-depth analysis of the relationship between the perceptions of plagiarism and other contextual, sociocultural and institutional variables, or the relationship between attitudes toward plagiarism and students’ perceptions of various forms of plagiarism. Although our review shows that various factors can contribute to plagiarism, there is no taxonomy that can account for all these factors. Some suggestions for future research are provided in this review article. (shrink)

By arguments analogous to the ones which serve* M, I show thatcontra John Worrall and John Watkins, thesis-LW is testable; finally, (III) if we accept arguments for thesis-LW and* M we are left with a skeptical conclusion with respect to the choice of a historiographical model which Worrall by parity of reasoning should accept, but does not.

Scholars of classical philosophy have long disputed whether Aristotle was a dialectical thinker. Most agree that Aristotle contrasts dialectical reasoning with demonstrative reasoning, where the former reasons from generally accepted opinions and the latter reasons from the true and primary. Starting with a grasp on truth, demonstration never relinquishes it. Starting with opinion, how could dialectical reasoning ever reach truth, much less the truth about first principles? Is dialectic then an exercise that reiterates the prejudices of one's times and at (...) best allows one to persuade others by appealing to these prejudices, or is it the royal road to first principles and philosophical wisdom? In From Puzzles to Principles? May Sim gathers experts to argue both these positions and offer a variety of interpretive possibilities. The contributors' thoughtful reflections on the nature and limits of dialectic should play a crucial role in Aristotelian scholarship. (shrink)

Since the Nuremberg trials (1947–1949), informed consent has become central for ethical practice in patient care and biomedical research. Codes of ethics emanating from the Nuremberg Code (1947) recognize the importance of protecting patients and research subjects from abuses, manipulation and deception. Informed consent empowers individuals to autonomously and voluntarily accept or reject participation in either clinical treatment or research. In some cases, however, the underlying mental or physical condition of the individual may alter his or her cognitive abilities and (...) compromise the informed consent process. This is particularly true in chronic psychiatric conditions such as Treatment-Resistant Depression (TRD), where individuals may fail to respond to traditional antidepressant treatments (e.g., psychotherapy, pharmacotherapy). Moreover, it may raise further concerns for an individual’s motivation to consent and the level of understanding of the treatment or research procedure. This paper focuses on the informed consent process for Vagus Nerve Stimulation (VNS) in the treatment of individuals diagnosed with TRD. Specifically, the paper addresses how depression may affect the decision-making capacity of an individual and the potential ethical and legal impact of failure to appreciate the seven elements of the consenting process (competence, voluntariness, disclosure, recommendation, understanding, decision, and authorization). To ensure the protection of vulnerable individuals with psychiatric disorders such as TRD and promote ethical behavior in biomedical research and patient care while avoiding potential legal pitfalls, we propose a paradigm that requires a stringent evaluation process of decision-making capacity for informed consent.

Muslims accept the existence of prophets and the occurrence of miracles as a basis of faith. The issue whether miracles will emerge from the righteous or saints is debatable. All Islamic scholars have accepted the existence of spiritual miracles, such as the grace of Allah to his saintly servants in the form of glad tidings, peace of heart and perseverance in faith. However, the existence of sensible (ḥissī) miracles or extraordinary situations that a person would never be able to do (...) under normal circumstances such as resurrecting the dead, changing the nature of objects, talking with inanimate beings and animals, knowing the events of the unseen, reaching long distances in a short time, walking on water or in the air, etc. has been the subject of serious debate. Most notably Mutazilites as well as some Sunni scholars also rejected saintly miracles and they argued that such events could only occur for prophets -with Allah’s permission and creation- and that they were called miracles. They are also concerned that if the extraordinary acts of saints are accepted, the institution of prophecy and therefore the proof of the miracle may be harmed. One of those who accepted this view is the famous Ẓāhirī scholar Ibn Ḥazm (d. 456/1064), who grew up in Andalusia. He claimed that marvelous events would occur only on the hands of the prophets, and he argued that it cannot be possible for a rightful person, saints or wizard to do extraordinary acts. However, he considered the marvelous events attributed to some people -who were not known to be prophets in the Qur’an and hadiths- as the miracles of the prophet who lived in the period in question. Ibn Ḥazm, who accepted that extraordinary events occurred from some of the ṣaḥāba (Prophet’s companions) during the Prophet’s lifetime, claimed that it ended with the death of the Prophet. According to him, those who claim that such events took place after the Prophet Muhammad, are liars, dishonest and deceitful people. In this article, the nature and limits of miracles according to Ibn Ḥazm are discussed, and the role he assigned to miracles despite being a scholar of the ahl al-ḥadīth is evaluated. (shrink)

Few modern artists so consistently embodied a fuzzy logic of their own as did the Indian painter Maqbool Fida Husain (1915 – 2011). His critics tried to define him as a reckless defamer of Hindu values, but another way to define him is as a dutiful devotee of a vision that was inclusive, rather than exclusive, and that understood all boundaries and identities as fluid or blurry, rather than as fixed and immutable. Or one might say that Husain (...) strove to project what Ashis Nandy has called “Indian-style secularism,” celebrating creation, humanity, and beauty in the multiple religious forms of the subcontinent. Having lived and painted in India all his life, he was forced into exile in his nineties by right-wing Hindu politicians. In London, he continued to work on a new interpretation of Indian civilization as universally relevant, in a sequence of paintings with themes from the Mahabharata, while, in Doha, a royal patron commissioned him to paint a series relating Islamic and Christian civilization. The two series are shown, in this essay, to best exhibit Husain's view of “all distinctions” as “political, artificial.”. (shrink)

Review of: Husain Sarkar. A Theory of Method. xvii+ 229 pp., bibl., indexes. Berkeley/Los Angeles/London: University of California Press, 1983. $29.95. The subject of this book is best stated in the author's words: "A theory is about the world; a method is about theories; and, a theory of method is about methods" (p. 1). A theory of method seeks to offer a general framework within which to choose among methods. Through critical examination of the positions of Karl Popper, Imre (...) Lakatos, and Larry Laudan, Sarkar develops his own framework for evaluating methods, which includes two bold proposals: that the history of science cannot be used as an arbitrator among methods, and that methods should be chosen by testing the heuristic advice they give about which lines of scientific research to pursue further.

Abu Muhammad Ali b. Ahmed b. Hazm al-Andalusi (d. 456/1064), the greatest exponent of the Ẓahiriyya school, was a scholar producing important works with his identity as a jurist, hadith scholar, historian, literary man, and poet. He also persistently defended the understanding of Ahl as-Sunna against the sects that emerged within Islamic thought as he defended the superiority of Islam against other religions. In his works, he covered almost every topic of the kalam science; in this context, he was especially (...) interested in topics related to the possibility of prophethood, the prophethood of Muhammad and his being the last representative of the prophethood chain. Therefore, this study, based mainly on his works such as al-Fasl, al-Usul wa'l-Furu, ad-Durr fi ma Yecibu i'tikaduhu and Ilm al-Kalam ala Mazhab Ahl al-Sunnah wa'l-Jama'a, deals with the topics of the possibility of prophecy, the prophethood of Prophet Muhammad, and the role and importance of miracles in proving it in the view of Ibn Hazm. Almost all Islamic scholars have based their systems for recognizing prophets on the evidence of miracles. According to them, a person who claims to be a prophet must bring extraordinary evidence to confirm his claim, and it is necessary for him to do so in order to make his opponents religiously responsible. For an event to be considered evidence that confirms the prophet's claim and to be called a miracle, it must have some characteristics, such as: it must be a divine act; it must appear in an extraordinary manner; it must occur together with the claim of prophecy and challenge; and it must occur immediately after the claim of the prophet. Therefore, it is believed that evidence that possesses these characteristics can prove the correctness of the claimant without needing any other evidence. The kalam scholars only call those events as miracles, which have the characteristic of challenging the dozens of evidences that prove the prophet's truthfulness. Therefore, it is without a doubt that the concept of miracle is a special concept invented by kalam scholars. When looking at Ibn Hazm’s views on the subject, which form the backbone of the study, it is necessary to state the following: Firstly, Ibn Hazm explains that prophecy is possible, that God chooses and sends messengers among the people, and that there is no difference among the prophets in terms of belief principles. Ibn Hazm emphasizes the role of miracles in identifying prophets and bases his system on this principle. However, he does not show much care in using the term "miracles" in the way that Kalam scholars accept it and does not aim to explain or list the characteristics or attributes of miracles as seen in Kalam books. He uses the term "miracles," which have been conceptualized over a long period of time, for every extraordinary event that belongs to the prophets, without considering these sensitivities. The most striking aspect of Ibn Hazm's understanding of miracles is that he does not consider the attribute of challenge, which is defined as a condition of a miracle, as necessary. He criticizes those who accept the attribute of a challenge as an essential part of miracles and argues that such an understanding would limit the miracles of the Prophet Muhammad. If the attribute of the challenge is accepted as a condition, then extraordinary events such as the blessing of food and drink, the moaning of wood in the mosque, and some animals coming and expressing their complaints would be excluded from the scope of miracles. This would mean limiting the evidence of Prophet Muhammad's prophecy. According to him, the creator of extraordinary events is God, and He creates them only to confirm His messengers. The events that occur in the hands of a person who claims to be a prophet should be considered a miracle. Therefore, he has named every event that occurred through the prophets as a miracle, regardless of its context and nature. In conclusion, according to Ibn Hazm, there are two types of events that occur in nature: Normal events and miraculous events. He refers to the latter as miracles and limits them to only occurring in the hands of prophets. He believes that events that occur in the hands of prophets, whether they possess the characteristic of tahaddî or not, should be referred to as miracles. Events that occur in the hands of people other than prophets do not possess the characteristics of miraculous events. If such events are claimed to be miraculous, the evidence of the prophets will be damaged. Therefore, Allah creates these events only for His messengers. Therefore, in the view of Ibn Hazm, concepts such as miracles of saints (karamat), magic, and divine help (maunat) do not have a counterpart. In fact, his attitude coincides with the Mu'tazilite tradition. He tries to prevent criticism that can be directed at miracles by assigning miraculous events only to prophets. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 43.4 (2005) 490-491 [Access article in PDF] Husain Sarkar. Descartes' Cogito: Saved from the Great Shipwreck. New York: Cambridge University Press, 2003. Pp. xviii + 305. Cloth, $65.00. Descartes's first critics attacked his cogito, ergo sum as deficient; his present critics attack it as excessive. Either way, it is an Archimedean point in Descartes's world and merits a book-length study. In this (...) book, Husain Sarkar makes a powerful case that the cogito is not an argument, but rather an "experiment," generating an intuition enabling Descartes to retrieve a timber from what Bourdin called the "great shipwreck" of the hyperbolic doubt.Sarkar places the experiment within his own fresh readings of Descartes's philosophy. They will be illuminating to new Descartes scholars. Some readings will seem perverse or cryptic. Constructive passages illuminate more, polemic passages less, as when Sarkar finds seven flaws in Hintikka's cogito interpretation. Despite the polemic excesses, Sarkar writes with modesty, epitomized by his slogan, "Reason with them in the most courteous manner."With verve and imagination Sarkar presents the cogito as an experiment which can be carried out in any world at all and yields an intuition that qualifies as a Cartesian first principle. He suggests various implications of his interpretation—for example, for the epistemic role of will: "The will initially learns the limits that it must recognize only at the foot of the cogito... It is in the state of the cogito that the will learns what it means to be ineluctably inclined toward affirming a proposition, and what it is to be free" (256).What is the content of the intuited 'I exist'? Sarkar calls upon Robert Adams's notion of a "primitive thisness," entirely distinct from a substance's properties or "suchnesses," and upon David Lewis's thesis that besides knowing propositions a person can know a self-ascription of a property. Still, he makes no headway at all. True, the question is extraordinarily [End Page 490] difficult. It has not yielded appreciably to brilliant phenomenologists or brilliant students of direct reference and indexicality or, for that matter, me. The content of 'I' statements is a topic for another book, and no one I know of is writing it.In the book's centerpiece, Sarkar marshals a series of attacks on the cogito as argument. Sometimes they miss—more polemic overkill. Usually they hit home. Their cumulative effect is persuasive.Descartes says that "I think, therefore I exist" is the first principle of his philosophy (VI, 32; VIIIA, 7; V, 147: references are to the Adam and Tannery edition). But if the cogito were an argument, one of its premises would become his first principle.An argument requires movement of thought and that requires reliance on memory (X, 370 and 408), and in the cogito Descartes strips memory of its credentials (VII, 24, superseding the assurances of X, 368).An argument relies on logical principles, but Descartes suspects these and reasoning generally. In the First Meditation he calls into doubt the simplest mathematics; elsewhere he generalizes from mathematics to "self-evident principles" and to "all the arguments I had previously taken as demonstrative proofs" (VI, 32; IXB, 6; similar aspersions are cast in V, 137 and 139). (But see also Mark Olson, "Descartes' First Meditation: Mathematics and the Laws of Logic" JHP 26 [1988]: 407–438.)I'll add a wrinkle. Descartes's mouthpiece Eudoxus says you can use your own doubt to deduce facts that are even more certain than those commonly built upon the great principle that it is impossible that a thing should both exist and at the same time not exist (X, 522). The conclusion of any argument rests on such logical principles. If the cogito were an argument, its certainty could not exceed theirs. Descartes suggests here that it does.Sarkar also cites Descartes's denigrations of "logic," but these often pertain not to reasoning generally but to syllogistic logic. Thus Margaret Wilson took the cogito to be a nonsyllogistic argument. Still, Sarkar effectively deploys... (shrink)

Richard Janko's acclaimed translation of Aristotle's _Poetics_ is accompanied by the most comprehensive commentary available in English that does not presume knowledge of the original Greek. Two other unique features are Janko's translations with notes of both the _Tractatus Coislinianus_, which is argued to be a summary of the lost second book of the Poetics, and fragments of Aristotle’s dialogue On Poets, including recently discovered texts about catharsis, which appear in English for the first time.
