It is not a thing of little importance to consider association. It is of great importance from a psychological point of view; it makes all the difference. For a wise person is not always positive against a foolish person, nor is a good person always positive against a wicked one. The one who is positive cannot always be positive; he has his times when he must be negative for a change. Therefore association certainly brings to one that which is received by the contact, and there is a great wisdom in the saying that a person is known by his associates.
