"gay motes that people the sunbeams." Yet, with colossal audacity, this
thinking atom regards himself as the anthropocentric pivot around which
revolve the eternal purposes of the Universe. Knowing not whence he
came, why he is here, or whither he is going, man feels himself of
supreme importance, and certainly is of interest--to himself. Let us
hope that he has indeed a potency and importance out of all proportion
to his somatic insignificance. We know of toxins of such strength that
an amount too infinitesimal to be gauged may kill; and we know that
"the unit adopted in certain scientific work is the amount of emanation
produced by one million-millionth of a grain of radium, a quantity
which itself has a volume of less than a million-millionth of a cubic
millimetre and weighs a million million times less than an exceptionally
delicate chemical balance will turn to" (Soddy, 1912). May not man be
the radium of the Universe? At any rate let us not worry about his size.
For us he is a very potent creature, full of interest, whose mundane
story we are only beginning to unravel.

Civilization is but a filmy fringe on the history of man. Go back as far
as his records carry us and the story written on stone is of yesterday
in comparison with the vast epochs of time which modern studies demand
for his life on the earth. For two millions (some hold even three
millions) of years man lived and moved and had his being in a world very
different from that upon which we look out. There appear, indeed, to
have been various types of man, some as different from us as we are
from the anthropoid apes. What upstarts of yesterday are the Pharaohs in
comparison with the men who survived the tragedy of the glacial period!
The ancient history of man--only now beginning to be studied--dates
from the Pliocene or Miocene period; the modern history, as we know it,
embraces that brief space of time that has elapsed since the earliest
Egyptian and Babylonian records were made. This has to be borne in mind
