inclination whatever to laugh. The truth of the matter is far from being so simple.
But to return to our idea of disguise, which, as we have just shown, has been entrusted with the special mandate of arousing laughter. It will not be out of place to investigate the uses it makes of this power.
Why do we laugh at a head of hair which has changed from dark to blond? What is there comic about a rubicund nose? And why does one laugh at a negro? The question would appear to be an embarrassing one, for it has been asked by successive psychologists such as Hecker, Kraepelin and Lipps, and all have given different replies. And yet I rather fancy the correct answer was suggested to me one day in the street by an ordinary cabby, who applied the expression "unwashed" to the negro fare he was driving. Unwashed! Does not this mean that a black face, in our imagination, is one daubed over with ink or soot? If so, then a red nose can only be one which has received a coating of vermilion. And so we see that the notion of disguise has passed on something of its comic quality to instances in which there is actually no disguise, though there might be.
