ABSTRACT
UMAN wants are primarily concerned with the H preservation of life, and are therefore of physiological nature. But as some biological peculiarities have been modified, as, for instance, the gradual disappearance of hair, a need arose to cover the body artificially, and to seek a shelter. Food, clothes, and shelter remain, for the greater part of humanity, still the chief source of wants, and therefore the basis of economic consumption. We have seen in the previous (fifth) chapter how economic factors influence the marriage-, birth-, and death-rates, and the two first phenomena form another biological feature of human life, aiming a t preservation of race. Preservation of life and preservation of race are both founded on the supply of economic means to satisfy them, and we have seen in the chapter " Economics and War " the variety of economic means and the consequent difference in the struggle for existence at the different stages of the progress of humanity.
