This book contains the papers of the Fourth Seminar in American Philosophy that was held in Winterthur, Switzerland, September 3-7, 1973. The subject of the seminar was the Philosophy of William James, which can be described as pragmatism. James himself understood by it »a new name for old ways of thinking« and put life, practice and action in the centre of his thinking – not the thinking itself as he regarded it as a »new« achievement in the development of mankind.
