If the topic be highly abstract, show its nature by concrete examples; if it be unfamiliar, make it figure as part of a story; if it be difficult, co… - William James

It is an odd circumstance that neither the old nor the new, by itself, is interesting; the absolutely old is insipid; the absolutely new makes no appeal at all. The old in the new is what claims the attention,—the old with a slightly new turn.

Now, my dear little girl, you have come to an age when the inward life develops and when some people (and on the whole those who have most of a destiny) find that all is not a bed of roses. Among other things there will be waves of terrible sadness, which last sometimes for days; irritation, insensibility, etc., etc., which taken together form a melancholy. Now, painful as it is, this is sent to us for an enlightenment. It always passes off, and we learn about life from it, and we ought to learn a great many good things if we react on it right. (For instance, you learn how good a thing your home is, and your country, and your brothers, and you may learn to be more considerate of other people, who, you now learn, may have their inner weaknesses and sufferings, too.) Many persons take a kind of sickly delight in hugging it; and some sentimental ones may even be proud of it, as showing a fine sorrowful kind of sensibility. Such persons make a regular habit of the luxury of woe. That is the worst possible reaction on it. It is usually a sort of disease, when we get it strong, arising from the organism having generated some poison in the blood; and we mustn't submit to it an hour longer than we can help, but jump at every chance to attend to anything cheerful or comic or take part in anything active that will divert us from our mean, pining inward state of feeling. When it passes off, as I said, we know more than we did before. And we must try to make it last as short as time as possible. The worst of it often is that, while we are in it, we don't want to get out of it. We hate it, and yet we prefer staying in it — that is a part of the disease. If we find ourselves like that, we must make something ourselves to some hard work, make ourselves sweat, etc.; and that is the good way of reacting that makes of us a valuable character. The disease makes you think of yourself all the time; and the way out of it is to keep as busy as we can thinking of things and of other people

Since belief is measured by action, he who forbids us to believe religion to be true, necessarily also forbids us to act as we should if we did believe it to be true. The whole defence of religious faith hinges upon action. If the action required or inspired by the religious hypothesis is in no way different from that dictated by the naturalistic hypothesis, then religious faith is a pure superfluity, better pruned away, and controversy about its legitimacy is a piece of idle trifling, unworthy of serious minds. I myself believe, of course, that the religious hypothesis gives to the world an expression which specifically determines our reactions, and makes them in a large part unlike what they might be on a purely naturalistic scheme of belief.
