Full Idea
A map that is identical in all respects with that which is mapped is just useless. So reductionism is not just a good thing - it is essential to thought.
Gist of Idea
Just as maps must simplify their subject matter, so thought has to be reductionist about reality

A Reaction
A useful warning, when thinking about truth. It is folly to want your thoughts to exactly correspond to reality. I want to understand the world, but not if it requires being the world.
