PAST, PRESENT, AND FUTURE	441
of years for Nature to bring man into existence, the dyna-
mic intelligence of man (homo sapietis) has transformed
life on earth so tremendously in the course of a few millen-
nia which constitute the sum of human history/ Secondly,
we have pointed to the conclusion that ' Man has remained
the same through all the varying conditions of life'; that
"Our knowledge of him in the twentieth century a.d. may
be fuller and more intimate than our knowledge of him in
the twentieth century b.c., but that makes no difference in
his fundamental character.1 For, ' He is still the intelligent

If by ' science' we mean a systematised body of knowledge,
we need not quarrel over the description of History as a

of the Past) is 'noble in its conception' and 'exalted in its
aim'. Occasionally we might come'across a cynic who opines
