In lieu of an abstract, here is a brief excerpt of the content:Louis Agassiz and the Platonist Story of Creation at Harvard, 1795-1846David K. NartonisIn 1846, naturalist Louis Agassiz took Harvard College by storm with his idealist approach to nature. In his initial lectures, repeated in New York the following year, Agassiz announced, "We have that within ourselves which assures us of participation in the Divine Nature and it is a particular characteristic of man to be able to rise in (...) that way above material Nature, and to understand intellectual existences." He then made it clear that by intellectual existences he meant a divine plan of creation. "What naturalists intend when they speak of what they call 'types'... may be easily understood by comparison. We all know that architects construct our dwellings according to plans conceived by them before the erection of the edifice."1 There is no doubt that Agassiz valued the careful collection of observational data. "It has only been step by step that man has acquired an insight into this plan."2 But his empiricism, if that is the right term, was entirely subordinate to apprehension of divine ideas, which alone deserved to be called science. In one recent account, The Metaphysical Club, which contains an excellent discussion of Agassiz's American career, author Louis Menand accurately describes this dual emphasis on observation and intuition. But Menand leaves unstated the problem of [End Page 437] Agassiz's welcome at Harvard, attributing his instant popularity to force of character.3A fuller explanation of Agassiz's welcome is to be found in the Scottish textbooks that dominated the Harvard philosophy curriculum prior to his arrival.4 Like Agassiz, textbook authors Thomas Reid, Dugald Stewart, and Thomas Brown recognized observation and intuition as twin sources of human knowledge. According to them, we observe our own moral tendencies and interpret them in the light of intuited ethical principles that even God must obey. Similarly, we observe nature and interpret its workings with the aid of intuited principles of common sense.5 There is no doubt that this dual emphasis on observation and intuition was entirely consistent with Agassiz's idealist biology. But his definition of species and genera as intellectual existences in the divine mind was not to be found in the official Scottish texts. In fact, Dugald Stewart, who governed the philosophy curriculum after 1820, insisted that there are "no existences in nature corresponding to general terms, and the objects of our attention in all our general speculations are not ideas but words."6 This was "long misunderstood by philosophers, who imagined that a generic word expresses an actual existence distinct from the individuals of which the genus is composed."7 Similarly, Thomas Brown lamented, "One fundamental error... as long as it retained its hold of the understanding, must have rendered all its energies ineffectual, by wasting them in search of objects, which had no real existence... I allude to... the various orders of universals."8 In this one respect, Stewart and Brown were in agreement with Alexander Pope when he counseled his many American readers "presume not God to scan" and ridiculed those who would "soar with Plato to th' empyreal sphere."9But Harvard students and faculty were also reading books that promoted the intellectual existences that Agassiz saw behind nature and the Scots did [End Page 438] not. Chief among these books were Plato's Works (ca. 360 BCE), Philo's De Opificio Mundi (20 BCE to 50 CE), Ralph Cudworth's The True Intellectual System of the World (1678), and John Norris's An Essay towards the Theory of the Ideal or Intellectual World (1701–04). These combined with such widely popular literature as John Milton's Paradise Lost (1668) and the prose works of Samuel Coleridge to form a kind of unofficial curriculum that ultimately made Agassiz's idealist view of nature especially welcome at Harvard.10 Modest at first, Harvard interest in intellectual existences bloomed with the appearance of books by Romantic writers on campus. In order to illustrate this long development, I will bolster my explanation with data from Harvard College library borrowing records—handwritten lists of the books borrowed by each library user during a one- or two-year period...

Nineteenth-century Harvard faculty and students looked to philosophical ideas about the proper and effective study of nature as the model of rationality to which their religion must conform. As these ideas changed, notions of rationality changed and so did Harvard religion.

This book is a defense of modal realism; the thesis that our world is but one of a plurality of worlds, and that the individuals that inhabit our world are only a few out of all the inhabitants of all the worlds. Lewis argues that the philosophical utility of modal realism is a good reason for believing that it is true.

Epistemic Evaluation aims to explore and apply a particular methodology in epistemology. The methodology is to consider the point or purpose of our epistemic evaluations, and to pursue epistemological theory in light of such matters. Call this purposeful epistemology. The idea is that considerations about the point and purpose of epistemic evaluation might fruitfully constrain epistemological theory and yield insights for epistemological reflection. Several contributions to this volume explicitly address this general methodology, or some version of it. Others focus on (...) advancing some application of the methodology rather than on theorizing about it. The papers go on to explore the idea that purposes allow one to understand the conceptual demands on knowing, examine how purposeful epistemology might shed light on the debate between internalist and externalist epistemologies, and further develop the idea of purposeful epistemology.

Christianity teaches that whenever evil is done, God had ample warning. He could have prevented it, but He didn't. He could have stopped it midway, but He didn't. He could have rescued the victims of the evil, but - at least in many cases - He didn't. In short, God is an accessory before, during, and after the fact to countless evil deeds, great and small. An explanation is not far to seek. The obvious hypothesis is that the Christian God (...) is really some sort of devil. Maybe He is a devil as popularly conceived, driven' by malice. Or maybe He is unintelligibly capricious. Or maybe He is a fanatical artist who cares only for the aesthetic quality of creation - perhaps the abstract beauty of getting rich variety to emerge from a few simple laws, or perhaps the concrete drama of human life with all its diversity - and cares nothing for the good of the creatures whose lives are woven into His masterpiece. Oust as a tragedian has no business providing a happy end out of compassion for his characters.) But no; for Christianity also teaches that God is morally perfect and perfectly benevolent, and that He loves all of His creatures; and that these things are true in a sense not a million miles from the sense in which we attribute morality, benevolence, or love to one another.

If a guilty offender is justly sentenced to be punished and an innocent volunteer agrees to be punished instead, is that any reason to leave the offender unpunished? In the context of mundane criminal justice, we mostly think not. But in a religious context, some Christians do believe in penal substitution as a theory of the atonement. However, it is not just these Christians, but most of us, who are of two minds. If the punishment is an imprisonment or death, (...) we do not believe in penal substitution. But if it’s a fine, even a big fine, we mostly do. (shrink)

Cicero, Lucullus 38: ‘…non potest animal ullum non adpetere id quod accommodatum ad naturam adpareat …’ From earliest childhood every man wants to possess something. One man collects horses. Another wants gold. Socrates has a passion for companions. He would rather have a good friend than a quail or a rooster. In this way, Socrates begins his interrogation of Menexenus. He then congratulates Menexenus and Lysis for each having what he himself still does not possess. How is it that one (...) gets a friend, Socrates asks? Since the nineteenth century many who have read these lines have found them repulsive. Scholars have damned the Lysis for its selfish egoism, for regarding persons as personal belongings. At the turn of the century some sought to discredit the dialogue as a forgery and a calumny. Others debated the dating of the dialogue as Socratic or Platonic, seeking whom to blame rather than whom to credit. And those who have regarded the dialogue as Platonic have tried to redeem it by detecting hints of Plato's theory of Forms. A few have attempted to salvage reputations by understanding the argument of the Lysis as a reductio of egoism, or else by invoking the loyalty of Socrates' friends and the history of Plato's friendship for Dion of Syracuse to speak up for their defence. Guthrie has condemned the dialogue as a failure of method and presentation , and Vlastos has pronounced it a failure of love: ‘The lover Socrates has in view seems positively incapable of loving others for their own sake, else why must he feel no affection for anyone whose good-producing qualities he did not happen to need?’ The Lysis appears to make no positive contribution to the Greek tradition on friendship when compared to the Symposium or the Phaedrus. And in the subsequent tradition, whatever Aristotle might have borrowed from the dialogue he uses for his own purposes. Aristotle too is quite critical of specific points raised in the Lysis. Now it might seem that Aristotle made a place for the selfish love of the Lysis in his own theory, as an inferior grade of utility love. But even this cannot be so, if we are to agree with recent studies of Aristotle's ethics. According to Aristotle, if a client is friendly to his benefactor because of the latter's usefulness, this utilitarian motive must accompany a genuine concern for the benefactor's own interest in that relation, if they are to be friends. Inferior and genuine friendship may differ in purpose but not in regard for the well-being of the beloved. This respect for the object of one's love has no parallel in the Lysis, according to the standard reading of the dialogue. (shrink)

Counterfactuals is David Lewis' forceful presentation of and sustained argument for a particular view about propositions which express contrary to fact conditionals, including his famous defense of realism about possible worlds and his theory of laws of nature.

Rosenberg argues that intentional generalizations in the human sciences cannot be law-like because they are not amenable to significant empirical refinement. This irrefinability is said to result from the principle that supposedly controls in intentional explanation also serving as the standard for successful interpretation. The only credible evidence bearing on such a principle would then need conform to it. I argue that psychological generalizations are refinable and can be nomic. I show how empirical refinement of psychological generalizations is possible by (...) considering concrete cases. A sufficiently detailed view of the role of psychological generalizations in interpretation allows us to find in psychological investigations instances of bootstrap testing. (shrink)

David Lewis (1941-2001) was Class of 1943 University Professor of Philosophy at Princeton University. His contributions spanned philosophical logic, philosophy of language, philosophy of mind, philosophy of science, metaphysics, and epistemology. In On the Plurality of Worlds, he defended his challenging metaphysical position, "modal realism." He was also the author of the books Convention, Counterfactuals, Parts of Classes, and several volumes of collected papers.

It is advisable to treat some sorts of discourse about fiction with the aid of an intensional operator "in such-And-Such fiction...." the operator may appear either explicitly or tacitly. It may be analyzed in terms of similarity of worlds, As follows: "in the fiction f, A" means that a is true in those of the worlds where f is told as known fact rather than fiction that differ least from our world, Or from the belief worlds of the community in (...) which the fiction originated.

This volume is devoted to Lewis's work in metaphysics and epistemology. Topics covered include properties, ontology, possibility, truthmaking, probability, the mind-body problem, vision, belief, and knowledge. The purpose of this collection, and the volumes that precede and follow it, is to disseminate more widely the work of an eminent and influential contemporary philosopher. The volume will serve as a useful work of reference for teachers and students of philosophy.

What knowledge would suffice to yield an interpretation of an arbitrary utterance of a language when such knowledge is based on evidence plausibly available to a nonspeaker of that language? it is argued that it is enough to know a theory of truth for the language and that the theory satisfies tarski's 'convention t' and that it gives an optimal fit to data about sentences held true, Under specified conditions, By native speakers.

A solution to the problem of intrinsic change for enduring things should meet three conditions. It should not replace monadic intrinsic properties by relations. It should not replace the having simpliciter of properties by standing in some relation to them. It should not rely on an unexplained notion of having an intrinsic property at a time. Johnston's solution satisfies the first condition at the expense of the second. Haslanger's solution satisfies the first and second at the expense of the third.

This is the first of a three-volume collection of David Lewis's most recent papers in all the areas to which he has made significant contributions. The purpose of this collection (and the two volumes to follow) is to disseminate even more widely the work of a preeminent and influential late twentieth-century philosopher. The papers are now offered in a readily accessible format. This first volume is devoted to Lewis's work on philosophical logic from the last twenty-five years. The topics (...) covered include: deploying the methods of formal semantics from artificial formalised languages to natural languages, model-theoretic investigations of intensional logic, contradiction, relevance, the differences between analog and digital representation, and questions arising from the construction of ambitious formalised philosophical systems. The volume will serve as an important reference tool for all philosophers and their students. (shrink)

In his note "can there be vague objects?" ("analysis", 1978), Gareth evans presents a purported proof that there can be no vague identity statements. Some readers think that evans endorses the proof and its false conclusion. Not so. His point is that those who put vagueness in the world, Rather than in language, Will have no way to fault the proof and no way to escape the false conclusion.

is the second-order theory of the part-whole relation. It can express such hypotheses about the size of Reality as that there are inaccessibly many atoms. Take a non-empty class to have exactly its non-empty subclasses as parts; hence, its singleton subclasses as atomic parts. Then standard set theory becomes the theory of the member-singleton function—better, the theory of all singleton functions—within the framework of megethology. Given inaccessibly many atoms and a specification of which atoms are urelements, a singleton function exists, (...) unique up to isomorphism.
