“Nothing is more dangerous than to stop working. It is a habit that can soon be lost, one that is easily neglected and hard to resume. A measure of day-dreaming is a good thing, like a drug prudently used; it allays the sometimes virulent fever of the over-active mind, like a cool wind blowing through the brain to smooth the harshness of untrammelled thought; it bridges here and there the gaps, brings things into proportion and blunts the sharper angles. But too much submerges and drowns. Woe to the intellectual worker who allows himself to lapse wholly from positive thinking into day-dreaming. He thinks he can easily change back, and tells himself that it is all one. He is wrong! Thought is the work of the intellect, reverie is its self-indulgence. To substitute day-dreaming for thought is to confuse poison with a source of nourishment.”

“A certain amount of reverie is good, like a narcotic in discreet doses. It soothes the fever, occasionally high, of the brain at work, and produces in the mind a soft, fresh vapor that corrects the all too angular contours of pure thought, fills up the gaps and intervals here and there, binds them together, and dulls the sharp corners of ideas. But too much reverie submerges and drowns. Thought is the labor of the intellect, reverie it's pleasure. To replace thought with reverie is to confound poison with nourishment.”

“Dreaming is another form of thinking, more concrete, more economical, more visual, and often more emotional than the thoughts of the day, but a thinking through of the day, nevertheless.”

“Thought is the labour of the intellect, reverie is its pleasure. To replace thought by reverie is to confound poison with nourishment.”

“I look forward confidently to the day when all who work for a living will be one with no thought to their separateness as Negroes, Jews, Italians or any other distinctions. This will be the day when we bring into full realization the American dream -- a dream yet unfulfilled.”

“Nothing makes time pass or shortens the way like a thought that absorbs in itself all the faculties of the one who is thinking. External existence is then like a sleep of which this thought is the dream. Under its influence, time has no more measure, space has no more distance.”
