The first question is, what is civilization? All men have certain physical needs, needs as warmth, food, and shelter. These needs man shares with animals. Savages spend, if not all, their time in the endeavor to satisfy them.
A civilization then cannot be a condition of affairs in which human beings merely satisfy ever more easily and elaborately their fundamental Physical needs and do nothing else.
It must be a condition in which they satisfy their need so easily and feel so secure from the danger that they have the time and energy to attend to other things and in particular, to the developments and demands of the mind and the spirit.
