Stephen Jay Gould

Stephen Jay Gould appears here as a representative of a dialectical approach to evolution. The distinction drawn around his position is not whether evolutionary change involves chance: hard Darwinists also recognize that natural selection works with contingent variations. The sharper disagreement concerns how novelty becomes organized into a new order, and whether adaptation can explain the emergence of the organism itself.

Intellectual Position

The passage associates Gould with a structural account of evolutionary change. On this view, the New does not arrive merely as one more element added to an existing arrangement; it emerges as a structure, a new order or harmony arising from chaos. The change may have a long gestation that can be recognized retrospectively, yet a final trigger produces a swift shift. This emphasis on the formation of a structured totality marks the difference from an account focused on selecting among variations.

Chance, Structure, and Adaptation

Gould’s distinction from hard Darwinism does not rest on denying contingency. The passage notes that hard Darwinists, too, understand how selection draws on aleatory variations, and may describe nature as reusing features for functions other than those for which they first developed. Gould’s dialectical position instead foregrounds the structural result: random acquisitions can combine into an unforeseen order, which cannot be reduced to the accumulation or reuse of individual traits.

The Circularity of Origins

The account also limits adaptation as an explanation of beginnings. To say that an organism emerges in order to adapt assumes that the organism is already there; survival may explain what happens to an existing organism, but cannot by itself explain how that organism first comes into being. The argument therefore turns on a logical circle between adaptation and the emergence of the entity that adapts. A newly emerging order, the passage concludes, also posits its environs: in relating to what is other, it establishes a relation to itself.
