ABSTRACT
An isolated community that remains subject to the same environmental conditions, and without selective mating, becomes, after a number of generations, stable in bodily form. The tools are found buried in the soil. Objectively the toolmaking of man of this period seems like an instinctive trait similar to the instincts of ants and bees. The repetition of the same act without change, generation after generation, gives the impression of a biologically determined instinct. The importance of the process of learning becomes more and more evident the nearer people approach the present period. The transition from Anglo-Saxon and Norman to English was rapid. The development of English since that time has been rather slow. Changes of unusual rapidity are due to the influence of European civilization upon primitive cultures. The choice of material depends partly upon environment, partly upon the state of inventions. More serious are the resistances in matters that evoke stronger emotional reactions.
