ABSTRACT
Acceptance of the doctrine of organic evolution determines certain ethical conceptions. The doctrine implies that the numerous organs in each of the innumerable species of animals, have been either directly or indirectly moulded into fitness for the requirements of life by constant converse with those requirements. There are many believers in the doctrine of evolution who seem to have no faith in the continued adaptability of mankind. While glancing but carelessly at the evidence furnished by comparisons of different human races with one another, and of the same races in different ages, they ignore entirely the induction from the phenomena of life at large. The egoistic sentiment of justice is a subjective attribute which answers to that objective requirement constituting justice—the requirement that each adult shall receive the results of his own nature and consequent actions.
