A Quote by Bertrand Russell on mind, introspection, meaning, life, wisdom, and perception

"The mind is a strange machine which can combine the materials offered to it in the most astonishing ways, but without material from the external world it is powerless, and unlike the sausage machine it must seize its material for itself, since events only become experiences through the interest we take in them; if they do not interest us, we are making nothing of them. The man, therefore, whose attention is turned within finds nothing worthy of his notice, whereas the man whose attention is turned outward can find within, in those rare moments when he examines his soul, the most varied and interesting assortment of ingredients being dissected and recombined into beautiful and instructive patterns."
