The aesthetically optimistic view of life in the last paragraph of Darwin’s On the Origin of Species contrasts with the evidence in his autobiography of a supposed perceptive colour blindness to the magnificence of nature. Accepting the theory of evolution as one of the scientific theories that has contributed to disenchantment, my aim is to delve into the Darwinian perception of natural beauty and solve this contrast of perceptions within the framework of the Weberian concept of “disenchantment of the world.” (...) To do this, I have carried out a computer-assisted study of Darwin’s language focusing on the frequency of aesthetic-emotional and religious adjectives and adverbs in the six editions of the Origin. A semantic analysis of the lexicon shows that, although disenchanted, Darwin perceives nature as aesthetically enhanced. I arrive at the conclusion that Darwin’s alleged colour blindness does not come from a loss of his capacity to aesthetically perceive nature, but from his loss of religious belief. (shrink)
