The Nature of Selection

The book that professionalised philosophy of biology as a serious analytic discipline. Sober separates what genuinely counts as a selective explanation from what popular biology routinely confuses — fitness, adaptation, and selection are not interchangeable concepts, and treating them as such leads to circular reasoning. Written with the precision of a philosopher of science but grounded in real biological examples, it remains the foundational text for anyone who wants to think clearly about what natural selection actually explains. The work laid the groundwork for decades of subsequent debate, including Sober's own later collaboration with David Sloan Wilson on group selection. Essential reading before touching any of the more recent philosophy of biology literature.
