CHAPTER XLVIII ENVIRONMENT AND DEVELOPMENT The biologists and physicians of today are inclined to underestimate the influence of the environment upon living beings and, on the other hand, to overestimate the effects of procreation. Only internal conditions are considered responsible for the development of the embryo, while the effectiveness of external conditions is almost denied, with the physical and mental characteristics of an individual irrevocably decided from the very start. Whatever future is held in store for the embryo and child remains supposedly unessential in comparison with the potentialities already contained in the generative cells of the parents and forebears. The main cause for the rejection of environment as a factor in development is the doubt with which the theory of the heredity of acquired characteristics is confronted. The question whether the effects of environment are hereditary is, to be sure, connected with, but essentially different from, the question whether the influences of environment affect the individual or its embryonic history at all. That this last question must be answered unconditionally in the affirmative cannot be contended by anybody now. The amount of proofs is so large that it seems superfluous to quote them (Chapter XXXVIII).

Seller's Description:
Very Good. First edition. Tall octavo. 414pp. Translated by A. Paul Maerker-Branden. Illustrated with black and white and color plates, several fold-out. Ownership stamp and signature of a noted American psychologist on the front fly. Binding a bit loose but sound, modestly worn save for a short tear at the crown and a small perforation on the upper shoulder, a very good copy. Kammerer's attempts to prove the tenets of Lamarckism were shown to be almost certainly fraudulent; he committed suicide in 1926.
