Sigmund Engel, The Elements of Child-protection
“ In the case of infants, there is no question of the struggle for existence. For their death-rate depends upon two factors—first, upon their inborn capacity; secondly, upon the conditions in which they are reared. The former factor is of far less importance in relation to infant mortality than it is in relation to child mortality. Only in an extremely limited sense is it possible, with regard to infants, to speak of a struggle for existence, in virtue of which the fittest survive. The infant is exposed to numerous dangers, in coping with which its inborn capacity hardly counts at all. ”
