The Philosophical Society of Finland was founded in 1873. In the beginning, it functioned as a seminar for advanced students. The Society has been continuosly active ever since, widening its scope and becoming an international meeting place and partner for various types of philosophy. The explosive growth and diversification in the recent decades has made it difficult to get a grasp even of a part of the philosophical activities centered in Finland. A comprehensive guide is necessary for finding the relevant academic and cultural publications in different corners of the world. This book is planned to serve the task in presenting the work of 75 professors of philosophy and related fields during the Twentieth Century.
