Lamarckism

“The propagation of acquired characteristics by heredity was too hastily and completely asserted; it is now perhaps in danger of being too summarily denied. Not Matter alone, but Life and Mind working upon Matter help to determine evolution. Heredity is only a material shadow of soul-reproduction, of the rebirth of Life and Mind into new forms. Ordinarily, as a constant factor or basis, there is the reproduction of that which was already evolved; for new characteristics to be propagated in the species they must have been accepted, received, sanctioned in the vital and mental worlds; then only can they be automatically self-reproduced from the material seed. Otherwise they are private and personal acquisitions and are returned into the State exchequer, the treasury of the subconscient, and do not go to the family estate. When the mind-world and life-world are ready, they are poured out freely on fit recipients. This is the reason why it is predisposition that is chiefly inherited. The psychical and vital force in the material principle is first impressed; when that has been done on a sufficient scale, it is ready for a general new departure and an altered heredity appears.”
