Jerry Fodor quotes:

[T]he 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.

Philosophers who pay for their semantics by drawing checks on Darwin are in debt way over their heads.

I rather doubt that life has a meaning. If I thought perhaps it did, and I wanted to find out what its meaning is, I don't imagine I'd ask someone whose credentials consist of a PhD in philosophy.

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

...if it isn't literally true that my wanting is causally responsible for my reaching, and my itching is causally responsible for my scratching, and my believing is causally responsible for my saying . . . If none of that is literally true, then practically everything I believe about anything is false and it's the end of the world.

There are lots of cases where we know more about how the world works than we do about how we know how it works. That's no paradox. Understanding the structure of galaxies is one thing, understanding how we understand the structure of galaxies is quite another. There isn't the slightest reason why the first should wait on the second and, in point of historical fact, it didn't. This bears a lot of emphasis; it turns up in philosophy practically everywhere you look.

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.

Who wins a... competition [between two traits] is massively context sensitive.

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.

I take it that computational processes are both symbolic and formal. They are symbolic because they are defined over representations, and they are formal because they apply to representations, in virtue of (roughly) the syntax of the representations.

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.

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 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.

On my bad days, I sometimes wonder what philosophers are for.

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.

...there are special sciences not because of the nature of our epistemic relation to the world, but because of the way the world is put together: not all natural kinds (not all the classes of things and events about which there are important, counterfactual supporting generalizations to make) are, or correspond to, physical natural kinds.

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.

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.

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.

...monetary exchanges have interesting things in common; Gresham's law, if true, says what one of these interesting things is. But what is interesting about monetary exchanges is surely not their commonalities under physical description. A natural kind like a monetary exchange could turn out to be co-extensive with a physical natural kind; but if it did, that would be an accident on a cosmic scale.

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....
