We may now consider this ancient evidence that Andes lay three miles away from Mantua in connection with Conway's remaining arguments and with Virgil's ‘own statement’ in his Bucolics.In the matter of the inscriptions, Conway's ‘impenitence’ does nothing to strengthen his case. All the points that he raises in an apparent refutation had been met by me. I had distinguished between public and private inscriptions, as Conway had not done in his earlier article, where he declared the period of the (...) two monuments to be ‘Virgil's own,’ the inscriptions being ‘cut in the style which marks the best work between 50 B.C. and A.D. 50.’ I had not, as he asserts, failed to notice the point that caps the climax of his recent article, that ‘the P. Magius who wrote the inscription of Casalpoglio … was related to Virgil's mother.’ I was inclined to date both inscriptions, with the approval of Professor Egbert, somewhere in the third quarter of the first century of our era, but ‘even allowing for them both a date as early as the end of the first century B.C.,’ which is apparently as far back as Conway means to stretch their date, I clamored for an inscription of the time of Virgil's birth if it were to serve as evidence for his birthplace. This point is not met by Conway. If Virgil was born at Pietole, his fame and his family could certainly have extended as far north as Casalpoglio and Calvisano at the time of his death in 19 B.C. Supposing that we knew on other evidence that he was born at Calvisano, the presence of an inscription with the name of Magius or Vergilius would corroborate that evidence. (shrink)

Kripke recently suggested viewing the intuitionistic continuum as an expansion in time of a definite classical continuum. We prove the classical consistency of a three-sorted intuitionistic formal system IC, simultaneously extending Kleene’s intuitionistic analysis I and a negative copy C° of the classically correct part of I, with an “end of time” axiom ET asserting that no choice sequence can be guaranteed not to be pointwise equal to a definite sequence. “Not every sequence is pointwise equal to a definite sequence” (...) is independent of IC. The proofs are by Crealizability interpretations based on classical ω-models ${\cal M}$ = $\left$ of C°. (shrink)

ABSTRACT David Hume’s attacks on causality and induction along with his celebrated is-ought dichotomy dealt a blow to the human mind from which Western civilization has never fully recovered. Centuries after his death, Hume remains immensely popular among academic philosophers, which only bolsters the myth that his skeptical arguments are unanswerable. In fact, his arguments are seriously flawed. The first part of this paper clarifies the basics of Hume’s philosophy, focusing on the epistemology in the Treatise and Enquiry. The second (...) part exposes the mistaken premises and assumptions in Hume’s arguments, demonstrating how Objectivism redeems the validity of human knowledge. (shrink)

“Probably Peirce’s best-known works are the first two articles in a series of six that originally were collectively entitled Illustrations of the Logic of Science and published in Popular Science Monthly from November 1877 through August 1878. The first is entitled ‘The Fixation of Belief’ and the second is entitled ‘How to Make Our Ideas Clear.’ In the first of these papers Peirce defended, in a manner consistent with not accepting naive realism, the superiority of the scientific method over other (...) methods of overcoming doubt and ‘fixing belief.’” — Robert Burch, “Charles Sanders Peirce,” entry in the Stanford Encyclopedia of Philosophy (2021 revision) -/- “Pragmatist epistemologies often explore how we can carry out inquiries in a self-controlled and fruitful way. (Where much analytic epistemology centres around the concept of knowledge, considered as an idealised end-point of human thought, pragmatist epistemology centres around the concept of inquiry, considered as the process of knowledge-seeking and how we can improve it.) So pragmatists often provide rich accounts of the capacities or virtues that we must possess in order to inquire well, and the rules or guiding principles that we should adopt. A canonical account is Peirce’s classic early paper ‘The Fixation of Belief‘. Here Peirce states that inquiry is a struggle to replace doubt with “settled belief“, and that the only method of inquiry that can make sense of the fact that at least some of us are disturbed by inconsistent beliefs, and will subsequently reflect upon which methods of fixing belief are correct is the Method of Science, which draws on the Pragmatic Maxim described above. This contrasts with three other methods of fixing belief: i) refusing to consider evidence contrary to one’s favored beliefs (the Method of Tenacity), ii) accepting an institution’s dictates (the Method of Authority), iii) developing the most rationally coherent or elegant-seeming belief-set (the A Priori Method).“ — Catherine Legg, “Pragmatism,” entry in the Stanford Encyclopedia of Philosophy (2021 revision).

Svirsky, Howard, and Berman address the U.S. Food and Drug Administration ’s oversight of tobacco products, the newest major area of regulation Congress assigned to the FDA. They discus...

This is one of the seminal articles of the pragmatist tradition where C.S. Peirce sets out his doctrine of doubt and belief --and their relationship to inquiry and clarity of our concepts. Originally published in the Popular Science Monthly; and widely available in reprints and collections of Peirce's writings.

That there is a personal, or private, dimension to religious and moral experience is obvious enough. On the face of things we may feel driven even to attach a sense which is essentially personal to the content of propositions relating to those areas of experience. ‘I know what I mean by what he says’, one might say. Or, it might be felt that there is a sense in which each man has a God who is uniquely his own. Just how (...) far can we push this idea of the irreducibly personal meaning, the necessarily individual content to such a moral or religious concept? Can we, in the end, give it an acceptable and unequivocal logical form? (shrink)

In his article, “The Logic of Liberty” (Journal of Ayn Rand Studies 12, no. 1), Roger Bissell uses an analytical diagram to show that Ayn Rand was wrong to characterize the differences between liberals and conservatives in terms of the mind-body dichotomy. Bissell claims that the key philosophical difference is not the mind-body dichotomy, but the malevolent universe premise. However, the diagram Bissell uses to discredit Rand’s position exhibits a serious design flaw: it presumes the mind-body split (...) by implying the metaphysical superiority of one over the other. This fundamental flaw in his analysis renders his criticism of Rand invalid. (shrink)

Leonard Peikoff’s “DIM Hypothesis” demonstrates that man’s cognitive need for integration is important historically. It reflects the motive power of philosophy, of man’s need to understand the world. But Peikoff’s theory lacks predictive power for America’s future. Today’s knowledge-based economy enables the average person to enjoy enhanced cognitive control over his life. Technology has transformed the American work experience in ways that teach one crucial connection: between the productive use of the mind (i.e., thinking, judgment) and human survival. This emerging (...) cognitive self-confidence mitigates the philosophical void left by cultural nihilism and creates an intellectual barrier to authoritarianism. (shrink)

C. S. Lewis sets out to persuade his audience of the importance and relevance of universal values such as courage and honor in contemporary society.

A repackaged edition of the revered author's classic work that examines the four types of human love: affection, friendship, erotic love, and the love of God—part of the C. S. Lewis Signature Classics series. C.S. Lewis—the great British writer, scholar, lay theologian, broadcaster, Christian apologist, and bestselling author of Mere Christianity, The Screwtape Letters, The Great Divorce, The Chronicles of Narnia, and many other beloved classics—contemplates the essence of love and how it works in our daily lives in one of (...) his most famous works of nonfiction. Lewis examines four varieties of human love: affection, the most basic form; friendship, the rarest and perhaps most insightful; Eros, passionate love; charity, the greatest and least selfish. Throughout this compassionate and reasoned study, he encourages readers to open themselves to all forms of love—the key to understanding that brings us closer to God. (shrink)

Philosophers readily talk about merely verbal disputes, usually without much or any explicit reflection on what these are, and a good deal of methodological significance is attached to discovering whether a dispute is merely verbal or not. Currently, metaphilosophical advances are being made towards a clearer understanding of what exactly it takes for something to be a merely verbal dispute. This paper engages with this growing literature, pointing out some problems with existing approaches, and develops a new proposal which builds (...) on their strengths. (shrink)
