attainments, the practice of seeing to the bottom of things, and so a perfect mental vision, form in themselves a mass which continues to increase in size, until the time comes when weakness shows itself, and the man's powers suddenly fail. The way in which these two distinguishable elements combine in the same nature,--the one absolutely unalterable, and the other subject to change in two directions opposed to each other--explains the variety of mental attitude and the dissimilarity of value which attach to a man at different periods of life. The same truth may be more broadly expressed by saying that the first forty years of life furnish the text, while the remaining thirty supply the commentary; and that without the commentary we are unable to understand aright the true sense and coherence of the text, together with the moral it contains and all the subtle application of which it admits. Towards the close of life, much the same thing happens as at the end of a _bal masqué_--the masks are taken off. Then you can see who the people really are, with whom you have come into contact in your passage through the world. For by the end of life characters have come out in their true light, actions have borne fruit, achievements have been rightly appreciated, and all shams have fallen to pieces. For this, Time was in every case requisite. But the most curious fact is that it is also only towards the close of life than a man really recognizes and understands his own true self,--the aims and objects he has followed in life, more especially the kind of relation in which he has stood to other people and to the world. It will often happen that as a result of this knowledge, a man will have to assign himself a lower place than he formerly thought was his due. But there are exceptions to this rule; and it will occasionally be the case that he will take a higher position than he had before. This will be owing to the fact that he had no adequate notion of the _baseness_ of the world, and that he set up a higher aim for himself than was followed by the rest of mankind. The progress of life shows a man the stuff of which he is made. It is customary to call youth the happy, and age the sad part of life. This would be true if it were the passions that made a man happy. Youth is swayed to and fro by them; and they give a great deal of pain and little pleasure. In age the passions cool and leave a man at rest, and then forthwith his mind takes a contemplative tone; the intellect is set free and attains the upper hand. And since, in itself, intellect is beyond the range of pain, and man feels happy just in so far as his intellect is the predominating part of him.
