It is like a general informing his soldiers that it is better to keep out of battle forever than to risk a single wound. Not so are victories either … - William James

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.

But psychology is passing into a less simple phase. Within a few years what one may call a microscopic psychology has arisen in Germany, carried on by experimental methods, asking of course every moment for introspective data, but eliminating their uncertainty by operating on a large scale and taking statistical means. This method taxes patience to the utmost, and could hardly have arisen in a country whose natives could be bored. Such Germans as Weber, Fechner, Vierordt, and Wundt obviously cannot ; and their success has brought into the field an array of younger experimental psychologists, bent on studying the elements of the mental life, dissecting them out from the gross results in which they are embedded, and as far as possible reducing them to quantitative scales. The simple and open method of attack having done what it can, the method of patience, starving out, and harassing to death is tried ; the Mind must submit to a regular siege, in which minute advantages gained night and day by the forces that hem her in must sum themselves up at last into her overthrow. There is little of the grand style about these new prism, pendulum, and chronograph-philosophers. They mean business, not chivalry. What generous divination, and that superiority in virtue which was thought by Cicero to give a man the best insight into nature, have failed to do, their spying and scraping, their deadly tenacity and almost diabolic cunning, will doubtless some day bring about.

No general description of the methods of experimental psychology would be instructive to one unfamiliar with the instances of their application, so we will waste no words upon the attempt.

This practically amounts to saying that much that it is legitimate to admire in this field need nevertheless not be imitated, and that religious phenomena, like all other human phenomena, are subject to the law of the golden mean. Political reformers accomplish their successive tasks in the history of nations by being blind for the time to other causes. Great schools of art work out the effects which it is their mission to reveal, at the cost of a one-sidedness for which other schools must make amends. We accept a John Howard, a Mazzini, a Botticelli, a Michael Angelo, with a kind of indulgence. We are glad they existed to show us that way, but we are glad there are also other ways of seeing and taking life. So of many of the saints we have looked at. We are proud of a human nature that could be so passionately extreme, but we shrink from advising others to follow the example.

An act has no ethical quality whatever unless it be chosen out of several all equally possible.
