In order to understand this, we must recall one or two facts. For one thing, though seriousness _may_ combine with a taste for the laughable, it is and remains fundamentally opposed to the playfulness of mirth. Philosophers are serious persons: their constructive thought is of the most arduous of human activities, and imposes on those who {396} undertake it an exceptional amount of serious concentration. Little wonder, then, if we so rarely find in them a marked fondness for the playful. The great and ineradicable gravity of the philosopher has been sufficiently illustrated in his theoretic treatment of our subject. In addition to this general reason, there are others and variable ones, differing with the kind of philosophic creed adopted, and with the temperamental attitude of the individual towards it. To begin with differences of creed, we must remember that a philosopher’s doctrine, while it may invest our common world and our common life with an aspect of indignity, may at the same time reduce these to mere semblances by setting them in contrast to the ideal region which it regards as the sphere of the veritable realities. In this way, as in Plato’s Idealism, we may see a quasi-religious tendency to lift men above the follies, deceptions and seeming evils of the world to the sublime verities. Such a doctrine, if consistently held, reserves but a small place for laughter—save perhaps for the happy smile of release or escape. Plato, the thinker of many moods, was able to adapt his doctrine to attitudes widely different from the half-poetic, half-religious one to which on the whole he leaned; and some of these proved to be compatible with a delicate vein of mirth. Perhaps one may find in Plato a reflection of the different attitudes of the gods—to communion with whom his spirit aspired—towards luckless and erring mortals: the serene indifference of those on the height, and a mild good-natured interest in what is seen below, which lends itself to the softer kind of ironical banter. What is told us of the laughter of the deities is always, perhaps, a little difficult to reconcile with their remote altitude and the detachment of spirit which seems proper to this; being, either in its mocking virulence, or {397} in its good-natured familiarity, rather too suggestive of a close attachment to our race; for which reason, by the way, philosophers, if they wish to soar god-wards and still to keep a laughing down-glance on their fellows, should beware lest they soar too high.
