Query: Author display *his* bias

Huston Smith has the credentials to write of religion and this is the strongest aspect of this book. Early on he tries to make the distinction between science and scientism, but he shows his own bias by insisting on arbitrary limitations on science itself. He is clearly personally bothered by the theory of evolution and spouts standard pseudo-science arguments that are just plain wrong. His insights into similarities of all religions are interesting, but the degree to which such broad generalizations are true is debateable.
