Without doubt Bonnet's most ambitious and remarkable study which earned him the designation of father of modern biology. This work of theoretical biology drawing its source from multi-disciplinary reflection and its postulate from Leibniz (the immortality of the soul) claims that the Earth periodically suffers universal catastrophes which destroy almost all life and that the survivors each time rise one degree on the evolutionary scale. Bonnet was the first to use the term evolution in a biological context. The work also prefigures experimental psychology. There would exist in each being germs which pre-exist it and ensure the survival of the species, Bonnet's thesis announcing the theories and discoveries of genes. It was blindness that in Bonnet put a stop to experimentation and engaged him on the path of philosophical reflection.
