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.

The content of a thought depends on its external relations; on the way that the thought is related to the world, not on the way that it is related to other thoughts.

No doubt, intuitions deserve respect. ...[but] I think that it is always up for grabs what an intuition is an intuition of. At a minimum, it is surely sometimes up for grabs.

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.

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

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.

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.
