Philosophy of Biology

The successor to Sober's 1993 manual as the standard introduction to philosophy of biology — more updated, equally clear.
Godfrey-Smith covers natural selection, adaptation, species, genetics, and the relationship between biology and the social sciences with a philosopher's precision and a biologist's grounding.
What sets this apart is his ability to present genuine open questions as open questions, rather than pretending consensus exists where it does not.
The book benefits from two decades of additional debate, particularly on multilevel selection and the extended evolutionary synthesis.
Short, dense, and remarkably well-written — it does not waste a sentence. The ideal starting point for the philosophy of biology line in this library.
Central argument
Godfrey-Smith argues that the core concepts of biology — natural selection, adaptation, fitness, species — are not simply empirical discoveries but philosophically contested frameworks whose meaning depends on how we interpret the structure of evolutionary theory itself. Rather than resolving these debates artificially, he maps the genuine disagreement: whether selection operates primarily at the gene, organism, or group level; whether the extended evolutionary synthesis requires revising or merely supplementing the Modern Synthesis; how biological concepts translate (or fail to translate) into social explanation. The book's central claim is that philosophical clarity about these foundations is a prerequisite for doing good biology, not a luxury added after the science is settled.
Critique
Because Godfrey-Smith writes as a philosopher of science engaging with biology, the book is necessarily more comfortable with conceptual analysis than with the messy empirical practice of working biologists — a gap that occasionally makes the philosophical tidiness feel like its own distortion. His treatment of the extended evolutionary synthesis, while acknowledging the debate, arguably understates how much the disagreement is sociological and institutional as well as theoretical, which matters for understanding why scientific consensus forms or fails to form. A reader wanting to understand how paradigm shifts actually happen in science, as opposed to how their logical structure can be reconstructed, will need to look elsewhere.
Why it matters for product
The multilevel selection debate — whether adaptation is best explained at the gene, organism, or group — maps directly onto one of the hardest organizational design problems in product: deciding at which level to optimize when team incentives, feature metrics, and portfolio outcomes are in tension. Godfrey-Smith's insistence on holding open questions open rather than forcing false consensus is a concrete discipline for product strategy: it pushes against the organizational habit of declaring a framework settled (OKRs, discovery cadences, platform vs. vertical) before the evidence justifies it. A CPO who internalizes his method will run strategy reviews differently — distinguishing what is genuinely resolved from what is being treated as resolved for the sake of organizational comfort.
