“Parts and wholes evolve in consequence of their relationship, and the relationship itself evolves.”
The Dialectical Biologist (1985), co-written with Richard Levins, Introduction, p. 3.
Context: Parts and wholes evolve in consequence of their relationship, and the relationship itself evolves. These are the properties of things that we call dialectical: that one thing cannot exist without the other, that one acquires its properties from its relation to the other, that the properties of both evolve as a consequence of their interpenetration.
