Brought face to face with these blurred copies
of himself, the least thoughtful of men is
conscious of a certain shock, due perhaps, not
so much to disgust at the aspect of what looks
like an insulting caricature, as to the awakening
of a sudden and profound mistrust of time-
honoured theories and strongly-rooted
prejudices regarding his own position in nature,
and his relations to the under-world of life;
while that which remains a dim suspicion for
the unthinking, becomes a vast argument,
fraught with the deepest consequences, for all
who are acquainted with the recent progress of
the … sciences.
