How can there be?
Can the same nature be a lover of wisdom and a lover of falsehood?
Never.
The true lover of learning then must from his earliest youth, as far as in him lies, desire all truth?
Assuredly.
But then again, as we know by experience, he whose desires are strong in one direction will have them weaker in others; they will be like a stream which has been drawn off into another channel.
True.
He will be absorbed in the pleasures of the soul, and therefore temperate and the reverse of covetous or mean. He whose desires are drawn towards knowledge in every form will be absorbed in the pleasures of the soul, and will hardly feel bodily pleasure—I mean, if he be a true philosopher and not a sham one.
That is most certain.
