Pry not into the souls of others; but rather look straight to the goal whither nature is leading you; whither the nature of the Universe by external events, and whither your own nature by the tendency of your own action. Each being must perform the part for which it was created. Now all other beings are created for the sake of those among them which have reason; as all lower things exist for the sake of things superior to them; and reasoning beings were created for one another. The leading principle in man's nature, then, is the social spirit; and the second is victory over the solicitations of the body. For it is proper to the workings of reason to set bounds to themselves, and never to be overpowered by the calls of sense or by the stirrings of passion, both of which are animal in their nature. The intellect claims to reign over these, and never to be subjected to them; and rightly, because it is equipped to command and use all the lower powers. The third element in the constitution of a reasoning being is caution against rashness and error. Let the soul go forth straight upon her way in the possession of these principles, and she stands seized of her full estate.
