“There are manifold tones of mental life, or, in other words, our psychic life may be lived at different heights, now nearer to action, now further removed from it, according to the degree of our attention to life.”

“It may be argued again that dissatisfaction with our life's endeavor springs in some degree from dulness. We require higher tasks, because we do not recognise the height of those we have.”

“A purely mental life may be destructive if it leads us to substitute thought for life and ideas for actions. The activity proper to man is purely mental because man is not just a disembodied mind. Our destiny is to live out what we think, because unless we live what we know, we do not even know it. It is only by making our knowledge part of ourselves, through action, that we enter into the reality that is signified by our concepts.”

“We plan our lives according to a dream that came to us in our childhood, and we find that life alters our plans. And yet, at the end, from a rare height, we also see that our dream was our fate. It's just that providence had other ideas as to how we would get there. Destiny plans a different route, or turns the dream around, as if it were a riddle, and fulfills the dream in ways we couldn't have expected.”

“The endless cycle of idea and action,Endless invention, endless experiment,Brings knowledge of motion, but not of stillness;Knowledge of speech, but not of silence;Knowledge of words, and ignorance of the Word.All our knowledge brings us nearer to our ignorance,All our ignorance brings us nearer to death,But nearness to death no nearer to God.Where is the Life we have lost in living?Where is the wisdom we have lost in knowledge?Where is the knowledge we have lost in information?The cycles of Heaven in twenty centuriesBring us farther from God and nearer to the Dust.”

“Our instinctive apparatus consists of two parts- the one tending to further our own life and that of our descendants, the other tending to thwart the lives of supposed rivals.”
