Darwin’s “dangerous idea” is clearly held forth and reiterated throughout the book— that all products of evolutionary change, from orchid shape to human intelligence, are manufactured at the algorithmic level. Dennett argues that no matter how impressive the result, the fundamental process involves a set of individually mindless steps which require no intelligent supervision.

Dennett’s argument is carefully constructed and skillfully presented. First, at the level of style, he writes in an amusing and unaffected manner, realizing that rigorous philosophical arguments are usually ignored by everyone outside the discipline. Second, at the level of argument, he has confronted the necessary multiplicity of factors by grouping them into three categories, each designed to build upon the previous one in order to provide an accumulating weight of evidence in favor of mindless algorithmic evolution. Just as Darwin had hit upon the Principle of Accumulation of Design to explain the scientific processes involved in evolution, Dennett employs the Principle of an Accumulation of Evidences to convince readers that Darwin was right.

The most direct threat which Dennett sees to full acceptance of the theory of mindless evolution is the popular scientific writing of Stephen Jay Gould. According to his theory of punctuated equilibrium, radical contingency rather than persistent and gradual adaptation dictated the pace of evolutionary development. Dennett argues that Gould is vainly attempting to...
