Each thing, as far as it can by its own power, strives to persevere in its being
Conatus (Latin for effort; endeavor; impulse, inclination, tendency; undertaking; striving) is a term used in early philosophies of psychology and metaphysics to refer to an innate inclination of a thing to continue to exist and enhance itself. This “thing” may be mind, matter or a combination of both.
Over the millennia, many different definitions and treatments have been formulated by philosophers. Seventeenth-century philosophers René Descartes, Baruch Spinoza, and Gottfried Leibniz, and their Empiricist contemporary Thomas Hobbes made important contributions.
The history of the term conatus is that of a series of subtle tweaks in meaning and clarifications of scope developed over the course of two and a half millennia. Successive philosophers to adopt the term put their own personal twist on the concept, each developing the term differently such that it now has no concrete and universally accepted definition.
