Psychology is a science, and teaching is an art; and sciences never generate arts directly out of themselves.

Our errors are surely not such awfully solemn things. In a world where we are so certain to incur them in spite of all our caution, a certain lightness of heart seems healthier than this excessive nervousness on their behalf.

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!.

The lunatic's visions of horror are all drawn from the material of daily fact. Our civilization is founded on the shambles, and every individual existence goes out in a lonely spasm of helpless agony.

The attitude of unhappiness is not only painful, it is mean and ugly. What can be more base and unworthy than the pining, puling, mumping mood, no matter by what outward ills it may have been engendered? What is more injurious to others? What less helpful as a way out of the difficulty? It but fastens and perpetuates the trouble which occasioned it, and increases the total evil of the situation. At all costs, then, we ought to reduce the sway of that mood; we ought to scout it in ourselves and others, and never show it tolerance.

No living person is sunk so low as not to be imitated by somebody.

What interest, zest, or excitement can there be in achieving the right way, unless we are enabled to feel that the wrong way is also a possible and a natural way, nay, more, a menacing and an imminent way? And what sense can there be in condemning ourselves for taking the wrong way, unless we need have done nothing of the sort, unless the right way was open to us as well? I cannot understand the willingness to act, no matter how we feel, without the belief that acts are really good and bad.
