As God is Wisdom, Wisdom is Science. Our beliefs, thoughts and opinions can change. So when we say a person never changes, it is as much as to say he is only a brute. It is the Principle that never moves. This something is Wisdom.
Wisdom is the true man and error the counterfeit.
When Wisdom governs matter, all goes well. When error directs, all goes wrong. No man should have any credit over his fellow men unless he shows some superiority over the errors of his age. The man who is rich in this world's goods to the exclusion of some scientific capital cannot travel in the world of Science with his money. Wisdom contains no opinion or selfishness.
