The use of another technical expedient of wit, which has not yet been mentioned, is also dependent upon “the rediscovery of the familiar.” I refer to the factor of _actuality_ (dealing with actual persons, things, or events), which in many witticisms provides a prolific source of pleasure and explains several peculiarities in the life history of wit. There are witticisms which are entirely free from this condition, and in a treatise on wit it is incumbent upon us to make use of such examples almost exclusively. But we must not forget that we laughed perhaps more heartily over such perennial witticisms than over others; witticisms whose application now would be difficult, because they would require long commentaries, and even with that aid the former effect could not be attained. These latter witticisms contained allusions to persons and occurrences which were “actual” at the time, which had stimulated general interest and were endowed with tension. After the cessation of this interest, after the settlement of these particular affairs, the witticisms lost a part of their pleasurable effect, and a very considerable. Thus, for example, the joke which my friendly host made when he called the dish that was being served a “Home-Roulard,” seems to me by no means as good now as when the question of Home Rule was a continuous headline in the political columns of our newspaper. If I now attempt to express my appreciation of this joke by stating that this one word led us from the idea of the kitchen to the distant field of politics, and saved us a long mental detour, I should have been forced at that time to change this description as follows: “That this word led us from the idea of the kitchen to the very distant field of politics; but that our lively interest was all the keener because this question was constantly absorbing us.” The same thing is true of another joke: “_This girl reminds me of Dreyfus; the army does not believe in her innocence_,” which has become blurred in spite of the fact that its technical means has remained unchanged. The confusion arising from the comparison with, and the double meaning of, the word “innocence” cannot do away with the fact that the allusion, which at that time touched upon a matter pregnant with excitement, now recalls an interest set at rest. The many irresistible jokes about the present war will sink in our estimation in a very short time.
