urselves external agents acting as stimuli and
achieving transformations which have the character, not analysable
as to its causes, of being adapted to their end, that is, capable of
life." Incomplete, but very instructive too, are his discussions on
the causal and the teleological outlook, the necessity for both, and
the impossibility of eliminating the latter from the study of
nature. In a series of subsequent works, Driesch has defined and
strengthened this position, finally reaching the declaration:
"Darwin belongs to history, just like that other curiosity of our
century, the Hegelian philosophy. Both are variations on the theme,
'How to lead a whole generation by the nose!' " ("Biolog.
Zentralbl." 1896, p. 16). We are concerned with Driesch more
particularly in Chapter IX.
