In treating of our conduct to ourselves, Schopenhauer lays much stress on the recommendation that such proportion be preserved between the attention which we give to the present and that which we grant to the future, that the one will in nowise interfere with the other. As there are many who live for the hour and many who live for the future, the right measure is seldom attained; but, as Schopenhauer points out, the future, like the past, has a value which is more apparent than real. It is the present that is actual, it is the present that is certain, while the future, on the contrary, usually turns out in a manner totally different from our expectation. The distance which "robes the mountains" expands them in our thoughts, but the present alone is true and effective; and as it is therein that our existence exclusively rests, it should not only be hospitably received, but every hour that is free from vexation or pain should be enjoyed to the fullest extent, and not saddened with the memory of irrecoverable hopes, or darkened by apprehensions of the morrow. In other words, let the dead past bury its dead, and for the moment take Seneca for model, and agree with him that each day separately is a separate life. As for the future, it rests in the lap of the gods. "The only misfortunes concerning which we should alarm ourselves are those that are inevitable; but then, after all, how many are there of this nature? Misfortunes, broadly considered, are either possible and probable, or else certain, though in the indefinite future; and if we bother ourselves over all that _might_ come to pass, we would never enjoy a moment's repose." In order, therefore, that tranquillity may not be unnecessarily disturbed, Schopenhauer advises that possible misfortunes be looked upon as though they would never occur, and inevitable misfortunes as though they were still far distant. It is a curious fact that the blind, who of all people are usually pitied as the most unfortunate, possess, as a class, the calmest and most contented expression. This phenomenon may serve as some corroboration of a theory, which Schopenhauer expands at great length, that the narrower the circle of vision the greater the happiness; and conversely, the wider it is the greater the inquietude and torment. It is, then, in the simplicity and uniformity of life--so long, of course, as it does not engender weariness of mind--that the greatest measure of happiness is to be found. Under conditions of this description, which every poet from Horace to Joaquin Miller has more or less praised, the burden from which life is inseparable is borne most lightly, and existence flows like a rivulet, without tides or waves.
