If we are to create balanced human beings, capable of entering into world-wide co-operation with all other men of good will—and that is the supreme task of our generation, and the foundation of all its other potential achievements—we must give as much weight to the arousal of the emotions and to the expression of moral and esthetic values as we now give to science, to invention, to practical organization. One without the other is impotent. And values do not come ready-made: they are achieved by a resolute attempt to square the facts of one’s own experience with the historic patterns formed in the past by those who devoted their whole lives to achieving and expressing values.

If we are to express the love in our own hearts, we must also understand what love meant to Socrates and Saint Francis, to Dante and Shakespeare, to Emily Dickinson and Christina Rossetti, to the explorer Shackleton and to the intrepid physicians who deliberately exposed themselves to yellow fever. These historic  manifestations of love are not recorded in the day’s newspaper or the current radio program: they are hidden to people who possess only fashionable minds.

Virtue is not a chemical product, as Taine once described it: it is a historic product, like language and literature; and this means that if we cease to care about it, cease to cultivate it, cease to transmit its funded values, a large part of it will become meaningless, like a dead language to which we have lost the key. That, I submit, is what has happened  in our own lifetime.

—Lewis Mumford (1895-1990) Values for Survival, 1946
