Given how long philosophers have been at conceptual analysis (I mean the 20th century stuff), and how many have been doing it, what can we say are the two most important concept results of all that effort?

There are many levels of organization in nervous systems. Hence we aim to explain mechanisms at one level in terms of properties and dynamics at a lower level, and to fit that in with the properties at the higher levels.

I used to suspect that in the brain, time is its own representation. I now think the problem is so much more complicated. Initially I was rather impressed by the experiments showing that on complex problems, subjects who are distracted do better in getting an answer than either those who answer immediately or those who spend time reflecting on the problem.

Humility bids us to take ourselves as we are; we do not have to be cosmically significant to be genuinely significant.

I am less attracted to guesses about what cannot be done, than about making progress on a problem.

When philosophers try to understand consciousness, much of what they claim is not conceptual analysis at all, though it may be shopped under that description.

Analyzing a concept can (perhaps) tell you what the concept means (at least means to some philosophers), but it does not tell you anything about whether the concept is true of anything in the world.
