To me this appears the most satisfactory interpretation
of the present state
of Life on the surface
of the earth; despite a regrettable recrudescence
of racialism and nationalism which, impressive though it may be, and disastrous in its effect upon our private post-war lives, seems to have no scientific
importance in the overall process: for the reason that any human tendency to fragmentation,
regardless of its extent and origin, is clearly
of an
order of magnitude inferior to the planetary forces (geographic, demographic, economic and psychic) whose constantly and naturally growing pressure must sooner or later compel us willy - nilly to unite in some form
of human whole organized on the basis
of human solidarity.
