Leigh Van Valen

• "Evolution, like all other natural processes, is caused by changes in energy."
• "It would be good to keep an open mind, but not so open that anything can enter unimpeded."
• "My interests go beyond what the blurb indicates."
• "Natural selection maximizes a quantity which is, roughly, the energy used for growth and reproduction."
• "Scientific proposals are inappropriate for much theoretical work; when one knows just what one will do, it is done."
• "Homology is resemblance caused by a continuity of information."
• "It can be hard to tell a crank from an unfamiliar gear."
• "Why is the world green, if it is?"
• "What, really is an academic discipline? If we actively try to look at the world around (and in) us from a perspective which ignores received boundaries, the results may be surprising."
• "In most aspects of human history the notion of fitness is best represented by power."
• "Our first concern is with life itself, with the flow of energy which powers it."
• "Any intrusion of ideology into science is an invitation to wishful thinking."
