Balance in large measure is knowing the things that can be changed, putting them in proper perspective, and recognizing the things that will not change."
Actual knowledge is identical with its object: in the individual, potential knowledge is in time prior to actual knowledge, but in the universe as a whole it is not prior even in time. Mind is not at one time knowing and at another not. When mind is set free from its present conditions it appears as just what it is and nothing more: this alone is immortal and eternal (we do not, however, remember its former activity because, while mind in this sense is impassible, mind as passive is destructible), and without it nothing thinks.
The necessity of knowing a little about a great many things is the most grievous burden of our day. It deprives us of leisure on the one hand, and of scholarship on the other.
The first man of science was he who looked into a thing, not to learn whether it furnished him with food, or shelter, or weapons, or tools, armaments, or playwiths but who sought to know it for the gratification of knowing.
It wasn't the New World that mattered... Columbus died almost without seeing it; and not really knowing what he had discovered. It's life that matters, nothing but life - the process of discovering, the everlasting and perpetual process, not the discovery itself, at all.
