must we determine the utility of its function, which is a social
one. Such, let us say at once, will be the leading idea of all our
investigations. Laughter must answer to certain requirements of life
in common. It must have a SOCIAL signification.

Let us clearly mark the point towards which our three preliminary
observations are converging. The comic will come into being, it
appears, whenever a group of men concentrate their attention on one
of their number, imposing silence on their emotions and calling into
play nothing but their intelligence. What, now, is the particular
point on which their attention will have to be concentrated, and
what will here be the function of intelligence? To reply to these
questions will be at once to come to closer grips with the problem.
But here a few examples have become indispensable.

A man, running along the street, stumbles and falls; the passers-by
burst out laughing. They would not laugh at him, I imagine, could
they suppose that the whim had suddenly seized him to sit down on
the ground. They laugh because his sitting down is involuntary.

Consequently, it is not his sudden change of attitude that raises a
laugh, but rather the involuntary element in this change,--his
clumsiness, in fact. Perhaps there was a stone on the road. He

that, through lack of elasticity, through absentmindedness and a
kind of physical obstinacy, AS A RESULT, IN FACT, OF RIGIDITY OR OF
MOMENTUM, the muscles continued to perform the same movement when
the circumstances of the case called for something else. That is the
