Methodological individualism is the doctrine that psychological states are individuated with respect to their causal powers.

Self-pity can make one weep, as can onions.

To the best of my recollection, I became a philosopher because my parents wanted me to become a lawyer. It seems to me, in retrospect, that there was much to be said for their suggestion. On the other hand, many philosophers are quite good company; the arguments they use are generally better than the ones that lawyers use; and we do get to go to as many faculty meetings as we like at no extra charge.

The degree of confirmation assigned to any given hypothesis is sensitive to properties of the entire belief system... simplicity, plausibility, and conservatism are properties that theories have in virtue of their relation to the whole structure of scientific beliefs taken collectively. A measure of conservatism or simplicity would be a metric over global properties of belief systems.

The theory of natural selection reduces to a banal truth: if a kind of creature flourishes in a kind of situation, then there must be something about such creatures (or about such situations, or about both) in virtue of which it does so.

Faculty Psychology is getting to be respectable again after centuries of hanging around with phrenologists and other dubious types. By faculty psychology I mean, roughly, the view that many fundamentally different kinds of psychological mechanisms must be postulated in order to explain the facts of mental life. Faculty psychology takes seriously the apparent heterogeneity of the mental and is impressed by such prima facie differences as between, say, sensation and perception, volition and cognition, learning and remembering, or language and thought.

Suppose that the organism is given the problem of determining the analysis of a stimulus at a certain level of representation - e.g., the problem of determining which sequence of words a given utterance encodes. Since, in the general case, transducer outputs underdetermine perceptual analyses, we can think of the solution of such problems as involving processes of nondemonstrative inference. In particular, we can think of each input system as a computational mechanism which projects and confirms a certain class of hyputheses on the basis of a certain body of data.
