Philosophy is not a body of doctrine but an activity.

What people accept as justification shows how they think and live.

It seems to me that, in every culture, I come across a chapter headed 'Wisdom.' And then I know exactly what is going to follow: 'Vanity of vanities, all is vanity.'

I might say: if the place I want to get to could only be reached by way of a ladder, I would give up trying to get there. For the place I really have to get to is a place I must already be at now. Anything that I might reach by climbing a ladder does not interest me.
