It is what a man has thought out directly for himself that alone has true value. Thinkers may be classed as follows: those who, in the first place, think for themselves, and those who think directly for others. The former thinkers are the genuine, they think for themselves in both senses of the word; they are the true philosophers; they alone are in earnest. Moreover, the enjoyment and happiness of their existence consist in thinking. The others are the sophists; they wish to seem, and seek their happiness in what they hope to get from other people; their earnestness consists in this.

Dirks, trans." to mean that wisdom is timeless.
