Man is perishing. That may be, and if it is nothingness that awaits us let us so act that it will be an unjust fate. - Miguel de Unamuno

If a philosopher is not a man, he is anything but a philosopher; he is above all a pedant, and a pedant is a caricature of a man. The cultivation of any branch of science — of chemistry, of physics, of geometry, of philology — may be a work of differentiated specialization, and even so, only within very narrow limits and restrictions; but philosophy, like poetry, is a work of integration and synthesis, or else it is merely pseudo-philosophical erudition.

For the truth is that our doctrines are usually only the justification a posteriori of our conduct, or else they are our way of trying to explain that conduct to ourselves.

Reason, that which we call reason, reflex and reflective knowledge, the distinguishing mark of man, is a social product.
