At the first International Congress of Philosophy, held in Paris during the first five days of August 1900, Bergson read a short, but important, paper, "Psychological Origins of the Belief in the Law of Causality" ("Sur les origines psychologiques de notre croyance à la loi de causalité"). In 1900 Felix Alcan published a work which had previously appeared in the "Revue de Paris", entitled "Laughter" ("Le rire"), one of the most important of Bergson's minor productions. This essay on the meaning of comedy stemmed from a lecture which he had given in his early days in the Auvergne. The study of it is essential to an understanding of Bergson's views of life, and its passages dealing with the place of the artistic in life are valuable. The main thesis of the work is that laughter is a corrective evolved to make social life possible for human beings. We laugh at people who fail to adapt to the demands of society if it seems their failure is akin to an inflexible mechanism. Comic authors have exploited this human tendency to laugh in various ways, and what is common to them is the idea that the comic consists in there being "something mechanical encrusted on the living".
