Les bases de la morale évolutionniste

This volume opens a systematic attempt to place ethics on the same evolutionary footing as biology and sociology. Written at the turn of the twentieth century, it gathers material that Spencer once called “the data of ethics,” offering a historic snapshot of how scholars first linked natural selection to moral thought. The author lays out a clear, measured argument that moral feeling is not a mysterious gift but a product of the same forces that shape physical traits. Readers are invited to follow a line of reasoning that builds from individual instincts to the habits of whole societies.

In the first sections, the text explores how basic human impulses—self‑preservation, cooperation, and reciprocity—gradually become the foundations of notions such as duty, justice, and sympathy. It examines domestic relations, ceremonial customs, and political institutions as arenas where these instincts are refined and codified. By tracing the gradual emergence of moral norms, the work encourages listeners to reconsider contemporary ethical debates in light of their deep evolutionary roots, without venturing into later, more speculative chapters.
