Hence the behavior of an isolated part is, in general, different from its behavior within the context of the whole... Secondly, the actual whole shows properties that are absent from its isolated parts.

The biological theories have acquired a tremendous ideological [weltanschauliche], yes even public and political significance... The condition of biology, problematic in many respects, has led to the situation that the “philosophies of life” were until now by no means satisfactory from the scientific as much as the practical point of view; we see all the more clearly the importance of the theoretical clarification of biology.
