'In this admirably crisp and clear-headed essay, Tom Angier deftly charts a path forward for a form of natural law theory that reclaims species essences and natural teleology, issuing a bold challenge to reductive empiricist naturalisms. Keeping the normative grounded in the natural remains a live option, and one compatible with evolutionary biology. Highly recommended reading for natural law's defenders and detractors alike!'
