This book contains the contributions to an international symposium on Charles Sanders Peirce (1839-1914). Notwithstanding that much of Peirce's philosophical writings still are to be published, his contributions to contemporary philosophy can be felt in almost every field. The symposium was held at the Institute of Philosophy of the Katholieke Universiteit Leuven in May 1997. Its express aim was to examine Peirce's thought in terms of both its historical integrity and in the application of his thought to current problems. The contributions to this book present a comprehensive portrayal of the metaphysical and epistemologiecal strands in the thought of this multi-faceted thinker.
