We can also see that, historically, certain ideas have tended to go together: a Lamarckian view of evolution, with species arranged on a ladder and a linear, progressive concept of change, perhaps inevitably engendered prejudice as some evolved forms must he regarded as more advanced, or ‘higher’, than others. Many of the inequitable views on human races indirectly resulted from this Lamarckian view point. . . . . Modern Darwinism places considerable emphasis on chance events such as mutation and genetic drift. There is nothing about natural selection that supports a progression of populations towards an end goal or ‘higher’ state. In fact, the misrepresentation of evolution as progressive was to apparent to Darwin that is his note-books he reminded himself to ‘never say higher or lower, and evolutionary biologists now recognize that it is impossible to define any non-arbitrary criteria by which progress in evolution can be measured. As no variant can be regarded as more advanced than others, Darwinian evolution is inconsistent with racism and Social Darwinism. ~ Page 66 (Excerpt “Sense and Nonsense” ~ Kevin N.

The principle of uncertainty was never entirely accepted by some of the greatest modern physicists, Einstein foremost among them, who was unwilling to admit that “God plays at dice.” Certain schools have retained it for its operational usefulness but denied it the standing of an essential concept.. . . Page 115

Bergson, it will be recalled, beheld in evolution the expression of an absolutely creative force, in the sense that he imagined it as bent on no goal other than creation in itself and for its own sake. In this he stands at the opposite pole from the animist (whether Engels, Teilhard de Chardin, or optimistic positivists like Spencer,) who all regard evolution as the majestic unfolding of a program woven into the very fabric of the universe. For them, consequently, evolution is not really a creation but uniquely the “revelation” of nature’s hither unexpressed designs. . . . page 116
