In science, one learns the most by studying what seems to be the least.

Logic doesn't apply to the real world.

Anyone could learn Lisp in one day, except that if they already knew Fortran, it would take three days.

A computer is like a violin. You can imagine a novice trying first a phonograph and then a violin. The latter, he says, sounds terrible. That is the argument we have heard from our humanists and most of our computer scientists. Computer programs are good, they say, for particular purposes, but they aren’t flexible. Neither is a violin, or a typewriter, until you learn how to use it.

If you understand something in only one way, then you don't really understand it at all. The secret of what anything means to us depends on how we've connected it to all other things we know.

An ethicist is somebody who sees something wrong with whatever you have in mind.
