Full Idea
I do not wish to persuade anyone to philosophy: it is inevitable, it perhaps also desirable, that the philosopher should be a rare plant.

A Reaction
My immediate reaction is disagreement, but 'what if everybody' became a philosopher. The fear is that philosophy paralyses action, but it need not. Good philosophy is time-consuming. History would come to an end. The excitement of medieval history!
