Whats the difference between ontology and existentialism?
Ontology is the metaphysical study of what exists and why. And we’re talking at a very nuts and bolts level. Existentialism is a philosophical system. As such, it includes a number of metaphysical claims, some of which are ontological in nature and some of which are not. One of existentialism’s classic ontological claims is that ‘existance precedes essence’ – things exist before they have a nature and a purpose.
