I have often thought the best way to define a man's character would be to seek out the particular mental or moral attitude in which, when it comes upon him, he felt himself most deeply and intensely active and alive. At such moments there is a voice inside which speaks and says: This is the real me!.
William JamesPretend what we may, the whole man within us is at work when we form our philosophical opinions. Intellect, will, taste, and passion co-operate just as they do in practical affairs; and lucky it is if the passion be not something as petty as a love of personal conquest over the philosopher across the way.
William James
