We need wisdom

by Kevin Birnbaum

From Small is Beautiful by E.F. Schumacher, p. 33:

In short, we can say today that man is far too clever to be able to survive without wisdom. No one is really working for peace unless he is working primarily for the restoration of wisdom. The assertion that “foul is useful and fair is not” is the antithesis of wisdom. The hope that the pursuit of goodness and virtue can be postponed until we have attained universal prosperity and that by the single-minded pursuit of wealth, without bothering our heads about spiritual and moral questions, we could establish peace on earth, is an unrealistic, unscientific, and irrational hope.

Where is this wisdom to be found?
