A construção de “existe” como um predicado de primeiraordem ou real é defendida contra a ortodoxia prevalente.

Some have supposed that morality has its basis in altruistic emotions implanted in accordance with the standard principles of natural selection. It is argued, to the contrary, that the falsity of group selection theory precludes founding genuine altruism on such a basis, and that the correct theory of evolution renders morality possible only if a cognitivist conception of moral psychology is accepted. Some independent reasons are given for favouring that conception over its noncognitivist rival. Morality is then claimed to be (...) a necessary corollary of advanced intelligence, so that morality cannot easily be selected against. Finally, the bearing of the foregoing considerations on the normative contention commonly labelled 'species-ism' is assessed; it is concluded that a proper view of morality suggests the inclusion of (other) animals within its domain of concern.

A puzzle about false judgement is raised in the Theaetetus (187d-200c), but not successfully answered there. On the proposed account, the confusion that explicitly vitiates Theaetetus’ final attempt to define knowledge is already at work implicitly in this puzzle. Theaetetus shares popular assumptions about knowledge (epistēmē), but also accepts that there are cognitive constraints on judgement (doxa): the puzzle arises because he fails to distinguish the one cognitive condition from the other.

In its most general form, the issue of intentionality takes the following shape: How can something be about something else? In basic cases, this relation is one between a subjective occurrence and a state of affairs, allowing the problem of intentionality to be articulated in this manner: What makes it the case that a subjective occurrence has the capacity to be about something external to it? The views of John McDowell on intentionality form the focus of this article. They are (...) examined through the notion of content and via the later Wittgenstein's standpoint on content and intentionality. The main objective is to reach a conspicuous perspective of McDowell's stance on intentionality in order to uncover its presuppositions. This leads to the identification of a pivotal point of tension in McDowell's philosophical commitments, in particular the extent to which he can legitimately claim to be a quietist. (shrink)

In this paper I explore a famous part of Plato’s Theaetetus where Socrates develops various models of the mind (picturing it first as a wax tablet and then as an aviary full of specimen birds). These are to solve some puzzles about how it is possible to make a mistake. On my interpretation, defended here, the discussion of mistakes is no digression, but is part of the refutation of Theaetetus’s thesis that knowledge is “true doxa”. It reveals that false doxa (...) is possible only if there is a certain stock of abstract knowledge, conceptual knowledge, that is not awareness of the particular individual that is being described. The individual must be identified under some description, or seen as something of a certain kind. Error can only occur if the description applied misdescribes the situation, but then if it is to be applied falsely it must first have been known from somewhere else. So knowledge cannot be reduced to the application of descriptions to particulars, but is to be found in the prior possession of abstract descriptions that can be deployed in identifying particular individuals on the ground.
