Speaking of Siris, he does in one paragraph what many a teacher can’t explain in an entire semester.
Evolution is not a means of creation; it isn’t very clear that the notion of a ‘means of creation’ is coherent. Evolution is a theory of generation; to be more precise, it is an account of how populations change when the generation and destruction of individuals in the population is linked to variation in the individuals, through things like selection and drift. This is something entirely different from creation; living things are not created through evolution, or by evolution, or any such thing. Evolution is part of the overall account of how living things are generated, of how they change from contrary to contrary, from being that to being other than that; it therefore is part of our account for why something is this rather than that.
