A counterpart of the question concerning the purpose and function of life (cp. pp. 190 ff.) is the question concerning its value. We meet here with two mutually opposed views, and between them with all conceivable attempts at compromise. One view says that this world is the best conceivable which could exist at all, and that to live and act in it is a good of inestimable value. Everything that exists displays harmonious and purposive co-operation and is worthy of admiration. Even what is apparently bad and evil may, from a higher point of view, be seen to be a good, for it represents an agreeable contrast with the good. We are the more able to appreciate the good when it is clearly contrasted with evil. Moreover, evil is not genuinely real; it is only that we perceive as evil a lesser degree of good. Evil is the absence of good, it has no positive import of its own. The other view maintains that life is full of misery and agony. Everywhere pain outweighs pleasure, sorrow outweighs joy. Existence is a burden, and non-existence would, from every point of view, be preferable to existence. The chief representatives of the former view, i.e., Optimism, are Shaftesbury and Leibnitz; the chief representatives of the second, i.e., Pessimism, are Schopenhauer and Eduard von Hartmann. Leibnitz says the world is the best of all possible worlds. A better one is impossible. For God is good and wise. A good God wills to create the best possible world, a wise God knows which is the best possible. He is able to distinguish the best from all other and worse possibilities. Only an evil or an unwise God would be able to create a world worse than the best possible. Whoever starts from this point of view will find it easy to lay down the direction which human action must follow, in order to make its contribution to the greatest good of the universe. All that man need do will be to find out the counsels of God and to act in accordance with them. If he knows what God's purposes are concerning the world and the human race, he will be able, for his part, to do what is right. And he will be happy in the feeling that he is adding his share to all the other good in the world. From this optimistic standpoint, then, life is worth living. It is such as to stimulate us to co-operate with, and enter into, it.
