There is relatively little comprehensive treatment of Heidegger’s theory of essences despite his ubiquitous use of essences. It is commonplace in contemporary analytic philosophy to view essences as the ground for true de re modal claims. I argue that Heidegger offers an account of essences that can best be understood as a type of relative essentialism. Relative essentialism is the view that more than one being can occupy the same space at the same time and those beings have distinct sets (...) of de re modal truths about them. Heidegger’s account of essences allows for true de re modal claims about a wide variety of things including scientific and cultural entities. At the same time, Heidegger rejects absolute essentialism: the view that there is one privilege collection of beings whose natures determine the truth values of de re modal claims about them. Relative essentialism is distinguished from contextual essentialism. (shrink)
