This paper will attempt to show that the interlude on necessity in the Timaeus narrative introduces a dualism into the Platonic cosmology, and that it is the material principle which is the positive cause of the disorder in the world. Furthermore, one can notice that in this work Plato is heading toward a concept of sensible substance that is close to the one which Aristotle will be defending.

Martin-Löf's constructive theory introduces, beside proof processes—the brouwerian mental construction—proof objects that could become the subject matter of a new kind of proof theory. In contradistinction to the classical approach, the proposition can then be defined as the set of its proofs. The lower level type theory is therefore a set theory, where the operators Σ and Π generalize the Cartesian product and the functional space to families of sets. To obtain the familiar logical constants, we have only to choose the logical reading of a : A. Σ and Π become ∃ and ∀, or, if there is no functional dependency, & and ⊃.

Like Wittgenstein, John Searle believes that much of analytic philosophy—especially the philosophy of mind—is founded on confusion and falsehood. Unlike Wittgenstein, he does not consider this condition to be endemic to philosophy. As a result, Searle's dual goals in The Rediscovery of the Mind are to rid the philosophy of mind of the fundamental confusions that plague it, and to set the field on the path toward genuine progress. Thus, the book opens with a chapter entitled “What's Wrong with the Philosophy of Mind?” and closes with “The Proper Study.” The text is a blend of old and new: Searle introduces several new ideas, the most important of which is his thesis of the unconscious, and incorporates them into theses that have figured prominently in his previous works. Even for those who will find little to agree with in this book, The Rediscovery of the Mind serves as a testament to the sheer scope and iconoclasm of Searle's work.

In a blurb on the dust jacket, Hilary Putnam describes Barry Allen's Truth in Philosophy as “a good, provocative, and important book” discussing issues of “common concern to both analytic and continental philosophers.” Yet Putnam admits that Allen's views “are ones that I myself am committed to combating and … I am certain most analytic philosophers will want to combat.” All the more reason to read this book, of course: know your enemy. Since Rorty clarified recent European philosophy for us in the 1980s, we have seen the continuing political transformation of what used to be an abstract, purely academic domain. Indeed, in his last chapter, Allen connects truth with politics in his discussion of Foucault:

The production and circulation of truth is as capable of complicity with tyranny, and all the more so with tutelage, as any instrument of government, and its products do not have to be false to have this effect.… Truth is inextricably situated amid all the major asymmetries of social power, (p. 173)

Foucault challenges the assumption of many that in liberal democracies (of which Putnam, after his youthful excesses, must consider himself a defender) truth and freedom need each other.

L'avènement de la modernité a privé la morale de ses sources traditionnelles et l'a laissée devant une dichotomie dont les termes sont également inacceptables: d'un côté l'historicisme avec son cortège de relativisme et de scepticisme et de l'autre, la raison impérative, universelle et vide de contenu moral. Entre les certitudes des Anciens, les dilemmes de la modernité et les abîmes du postmodernisme, la philosophie morale et politique contemporaine ne serait pourtant pas condamnée à l'impotence. La conviction de Charles Larmore est en effet que les diverses conceptions philosophiques qui nous ont successivement menés à pareille impasse nous offrent aussi les moyens d'en sortir. Cette conviction œcumenique est elle-même ancrée dans une ethique de la pensee qui devrait, comme l'auteur s'en explique dans l'introduction de Modernité et morale, nous détourner du dogmatisme et du monisme traditionnels de la philosophie. Sur cet arrière-plan métaphilosophique, l'auteur prétend done faire, des problèmes de la morale contemporaine, l'objet d'une discussion ouverte où il convie les philosophes de toutes tendances et de tous les temps.
