The philosophy of Raymond Ruyer was an important if subterranean influence on twentieth-century French thought, and explicitly engaged with by figures such as Maurice Merleau-Ponty, Georges Canguilhem, Gilbert Simondon, and Gilles Deleuze. The Genesis of Living Forms is Ruyer's most focussed and forceful analysis of a central but apparently paradoxical biological phenomenon that also presents serious problems for philosophy: embryogenesis. When a cat develops from the early stages of fertilization to an adult, what is it that makes it the same cat? How is it that a living being can at once be the same and constantly changing? Ruyer's answer to these questions unfolds through a detailed set of encounters with major scientific fields, from particle physics to social psychology, arguing that the paradox can only be dissolved by seeing the role that form plays in the ongoing development of living beings. In Ruyer's view, embryogenesis is a central problem not just in the life sciences; every thing must possess a relation to a form that is characteristic of it, from carbon atoms to embryos, and to embryologists themselves.

Although little known today, Raymond Ruyer was a post-World War II French philosopher whose works and ideas were significant influences on major thinkers, including Deleuze, Guattari, and Simondon. With the publication of this translation of Neofinalism, considered by many to be Ruyer's magnum opus, English-language readers can see at last how this seminal mind allied philosophy with science. Unfazed by the idea of philosophy ending where science began, Ruyer elaborated a singular, nearly unclassifiable metaphysics and reactivated philosophy's capacity to reflect on its canonical questions: What exists? How are we to account for life? What is the status of subjectivity? And how is freedom possible? Ha Neofinalism offers a systematic and lucidly argued treatise that deploys the innovative concepts of self-survey, form, and absolute surface to shape a theory of the virtual and the transspatial. It also makes a compelling plea for a renewed appreciation of the creative activity that organizes spatiotemporal structures and makes possible the emergence of real beings in a dynamic universe.
