etc., which may be explained as an unexpected economy of psychic expenditure. Therefore it surprises no one that these resulting pleasures urge the child to practice playing and impel it to continue without regard for the meaning of words or the connections between sentences. Playing with words and thoughts, motivated by certain pleasures in economy, would thus be the first step of wit.
This playing is stopped by the growing strength of a factor which may well be called criticism or reason. The play is then rejected as senseless or as directly absurd, and by virtue of reason it becomes impossible. Only accidentally is it now possible to derive pleasure from those sources of rediscovery of the familiar, etc., which is explained by the fact that the maturing person has then merged into a playful mood which, as in the case of merriment in the child, removes inhibitions. In this way only is the old pleasure-giving playing made possible, but as men do not wish to wait for these propitious occasions and also hate to forego this pleasure, they seek means to make themselves independent of these pleasant states. The further development of wit is directed by these two impulses; the one striving to elude reason and the other to substitute for the adult an infantile state of mind.
