Abstract

This dissertation critically examines Helmuth Plessner's philosophically ambitious explanation of laughter presented in his Laughing and Crying: A Study of the Limits of Human Behavior. The aim of this dissertation is to demonstrate that Plessner's philosophical anthropology makes a distinctive contribution to our knowledge of the human capacity to laugh and, in the process, to our knowledge of human nature. This dissertation is accordingly addressed not only to philosophers interested in the question of human nature, but to physiologists, psychologists, sociologists, and all other scientists interested in explaining laughter. ;Plessner, who lived from 1892 to 1985, was one of the founders and foremost representatives of the twentieth-century movement of thought known as philosophical anthropology, which he characterizes as "the systematic discussion of questions of the structure of human nature." Against Cartesian dualism, Plessner undertakes to investigate "how the psychological is clasped together with the physical." The project of Laughing and Crying , first published in German in 1940 and translated into English in 1970, is to investigate the conditions of possibility of these two forms of expression "in the basic figure of human existence under the spell of the body." ;Plessner's thesis in Laughing and Crying is that these two forms of expression outstandingly disclose "the secret composition of human nature," which in turn "constitutes the basis of laughing and crying." This dissertation is restricted to laughter in order to facilitate the exposition of this "secret composition," which Plessner names our "eccentric positionality." Chapter 1 establishes a role for philosophical reflection on the phenomenon of laughter in the light of physiological, psychological, and sociological findings. Chapter 2 discusses some of Plessner's earlier writings insofar as they form the background of and thus illuminate his approach to laughter. Chapter 3 examines and elaborates upon the development and details of Plessner's argument in Laughing and Crying. Chapter 4 assesses a criticism of Plessner's argument as "behaviorist." After locating Laughing and Crying within Plessner's corpus and Plessner's corpus within the movement of philosophical anthropology in his day, the conclusion addresses the question of the ongoing significance of this discipline of thought
