It simply isn't true, for example, that being big is in general better for fitness than being small except when there are effects of interacting variables; or that flying slow and high is in general better for fitness than flying fast and low except when there are effects of interacting variables; or that being monogamous is in general better for fitness than being polygamous... except when there are effects of interacting variables... It's not that the underlying generalizations are there but imperceptible in the ambient noise.

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

The data that can bear on the confirmation of perceptual hypotheses includes, in the general case, considerably less than the organism may know.

I hate relativism. I hate relativism more than I hate anything else, excepting, maybe, fiberglass powerboats. Surely, surely, no one but a relativist would drive a fiberglass powerboat.

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.

If, in short, there is a community of computers living in my head, there had also better be somebody who is in charge; and, by God, it had better be me.

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.
