Jean-Baptiste Lamarck is well known as a pre-Darwinian proponent of evolution. But much of what has been written on Lamarck, on his ‘Lamarckian’ belief in the inheritance of acquired characters, and on his conception of the role of the will in biological development mischaracterizes his views. Indeed, surprisingly little in-depth analysis has been published regarding his views on human physiology and development. Further, although since Robert M. Young’s signal 1969 essay on Malthus and the evolutionists, Darwin scholars have sought to (...) place Darwin’s work in its social and political context, this has yet to be done adequately for Lamarck. Here I address this gap. I argue that the will was of particular importance to Lamarck’s social commentary and his hopes for the transformation of the French people and nation. Further, I argue that if we are to really grasp Lamarck’s ideas and intentions we need to contextualize his works in relation to prevailing debates in France about the physiology of mind and morals and the future of the nation.

This paper argues that our modern concept of biological heredity was first clearly introduced in a theoretical and practical setting by the generation of French physicians that were active between 1810 and 1830. It describes how from a traditional focus on hereditary transmission of disease, influential French medical men like Esquirol, Fodéré, Piorry, Lévy, moved towards considering heredity a central concept for the conception of the human bodily frame, and its set of physical and moral dispositions. The notion of heredity (...) as a natural force, with a wide ranging capabilities of transmitting differentially both fundamental and accidental characters was generalized by that generation of physicians with the help of contemporary naturalists and physiologists. By 1830 the term hérédité was widespread, and it shared the explanatory and semantic qualities of traditional medical concepts like constitution and temperament. An analysis is given of the main developments that led to the conception of biological (including human) bodies as consisting of a layered, hierarchical organization of characters, differentially affected by the laws of conservation (Heredity) and change (Inneity, Variation). The mid-century work of the French physician Prosper Lucas, Traité Philosophique et Physiologique de L'Hérédité Naturelle, is shown to be the culmination of the efforts of several generations of French physicians towards having a feasible, complexly structured notion of how heredity works.

The seventeenth century was one of scientific fervour and of fundamental change in how the natural world was to be approached. With increased voyages abroad, the world was being drawn into Europe and each country wanted to be the first to capture the ‘Codex Naturae’. French physician/naturalists were examining and dissecting nature and Jesuit missionaries were documenting day-to-day life of First Peoples in the New World. The interplay between an ethnogeography and a scientific knowledge including an environmentally orientated medical geography (...) illustrate the contrast of approaches to health, humanity, and place.
