Full Idea
The last thing to dawn on philosophers is that they must no longer merely let themselves be given concepts, no longer just clean and clarify them, but first of all must make them, create them, present them and persuade in their favour.
Gist of Idea
Philosophers should create and fight for their concepts, not just clean and clarify them

A Reaction
Compare the disagreement between Wittgenstein (Idea 2937) and Keith Ansell Pearson (Idea 6870). The trouble is that now every book you read is creating new concepts, which usually fail to catch on. I agree, though, with Nietzsche.
