‎---- Troisième éditon AUGMENTEE DE L'ANALYSE DE L'OUVRAGE QUE Charles BONNET AVAIT DONNEE DANS LA PREFACE DE LA CONTEMPLATION DE LA NATURE ---- "Bonnet is considered one of the fathers of modern biology. He is distinguished for both his experimental research and his philosophy, which exerted a profound influence upon the naturalists of the eighteenth and nineteenth centuries... A true theoretician of biology, he exercised an enormous influence in this field and published works that caused a considerable stir... Bonnet was an enthusiastic champion of preformation, the theory postulating that the animal already existed in miniature in the germ cell. His discovery of parthenogenesis was, to him, proof that the female germ cell contains the preformed individual... This theory, which he christened "palingenesis" set forth the functional and structural notion of the cell, which was not stated formally until a hundred years later...". (DSB II pp. 286/287) ---- "Bonnet's theory of generation offered the best synthesis of 18th century ideas of development and remained a leading authority until Von Baer. Bonnet believed in the preformation of the embryo. He used many of Haller's arguments to support his own opinions. J. Needham calls him an organicistic preformationist for his objection to epigenesis lay in the fact that it apparently did not allow for the integration of the organism as a whole".
