The first text is s letter by Ruyer to Jean Piaget from October the 16th 1965. Piaget enounced a hard criticism to Ruyer’s Elements of psycho-biology : recognizing the quality of his scientific informations, he refused his explanation of scientific facts refering to a metaphysics of potential, finality and psychism, and defended the thesis that philosophy is not able to bring any authentic knowledge and that it is a possibility only for experimental sciences.
