However free in its purely literary aspect humour may be from all ulterior purpose and aim, the tale of its growth with us is largely interwoven with impulses received from outside sources and sources didactic and philosophical. Outwitting the devil, the theme that recurs again and again as the oldest form of farcical expression in mediæval Germany, meant dealing with the stresses of adverse circumstance. This was the first step taken on the road to humour in Germany. The Powers of Evil had all the brute force upon their side; there was no coping with them, except by sharpening one’s wits and irritating them by practical jokes until they might yield. The laugh that followed had all the hard ring of the victor’s triumphant scorn. Early satirical writings were imbued with a like spirit. There was the lash to be swung at some enemy, and derision at his downfall was tempered by no kindlier emotion. There was a grim attitude of self-defence throughout it all. Indeed, it is only in going back painfully step by step that one is enabled to discern in this early literature the germs of humour at all. The farces and puppet-shows at country fairs and the burlesques at the early theatre began to make room for the idea of retaliation. It became a question of clown against clown. The supremacy was never yielded long to one side. Laying aside all personal interest in the matter for the time being, there was an impartial shout of laughter at him who got the most kicks and cuffs. The popular mind began to rise above the situation, to put itself in the position of an unbiassed spectator, and to take delight in merely putting down whatever asserted itself. As an instance of this may be counted the practice of granting the devil, or a person disguised as such, a hearing in church on certain days of the year instead of the parish priest. Then the sense of discrepancy between things great and small, things important and unimportant, the world of the senses and the world of the spirit, began to enter the popular perception, the impossibility of reconciliation, and, as a consequence, the pleasure of turning this world topsy-turvy, and so demonstrating the supremacy of the individual. Side by side with this development, or partly perhaps based upon it, went the philosophic development. Thinkers, dreamers, and philosophers went on constructing a universe according to the laws of their individual minds, a universe containing nothing at all to be laughed at, and for many decades scholars were deeply buried in obstruse problems and finely-spun theories and systems, the lighter muse of poetry and art for the most part following but humbly and timorously from afar. But when philosophy and theology had spoken at large, and the mystery and fatal contradiction at the heart of things had not been unravelled, the pale brooding of some turned to melancholy, with others it turned to boisterous living and philosophic indifferentism.
