Everyone carries his own inch rule of taste, and amuses himself by applying it, triumphantly, wherever he travels.

Darwin's greatest achievement was to show that the appearance of purpose, planning, teleology (design), and intentionality in the origin and development of human and animal species was entirely an illusion. The illusion could be explained by evolutionary processes that contained no such purpose at all. But the spread of ideas through imitation required the whole apparatus of human consciousness and intentionality

It seemed to a number of philosophers of language, myself included, that we should attempt to achieve a unification of Chomsky's syntax, with the results of the researches that were going on in semantics and pragmatics. I believe that this effort has proven to be a failure. Though Chomsky did indeed revolutionize the subject of linguistics, it is not at all clear, at the end the century, what the solid results of this revolution are. As far as I can tell there is not a single rule of syntax that all, or even most, competent linguists are prepared to agree is a rule.

We do not live in several different, or even two different, worlds, a mental world and a physical world, a scientific world and a world of common sense. Rather, there is just one world; it is the world we all live in, and we need to account for how we exist as part of it.

Because we do not understand the brain very well we are constantly tempted to use the latest technology as a model for trying to understand it. In my childhood we were always assured that the brain was a telephone switchboard. . . Sherrington, the great British neuroscientist, thought the brain worked like a telegraph system. Freud often compared the brain to hydraulic and electromagnetic systems. Leibniz compared it to a mill. . . At present, obviously, the metaphor is the digital computer.
