What has made the European family of nations an improving, instead of a stationary portion of mankind? Not any superior excellence in them, which, when it exists, exists as the effect, not as the cause; but their remarkable diversity of character and culture. Individuals, classes, nations, have been extremely unlike one another: they have struck out a great variety of paths, each leading to something valuable; and although at every period those who travelled in different paths have been intolerant of one another, and each would have thought it an excellent thing if all the rest could have been compelled to travel his road, their attempts to thwart each other's development have rarely had any permanent success, and each has in time endured to receive the good which the others have offered. Europe is, in my judgment, wholly indebted to this plurality of paths for its progressive and many-sided development.

Of individuality, as one of the elements of well-Being p.136" to mean that wisdom is timeless.
