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.

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

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.

...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.

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.

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