One of the key idea of existential is that human existence is in some way ‘on its own’; anxiety (or anguish) is the recognition of this fact. Anxiety here has two important implications. First, most generally, many existentialists tended to stress the significance of emotions or feelings, in so far as they were presumed to have a less culturally or intellectually mediated relation to one’s individual and separate existence. This idea is found in Kierkegaard, as we mentioned above, and in Heidegger’s discussion of ‘mood’; it is also one reason why existentialism had an influence on psychology. Second, anxiety also stands for a form of existence that is recognition of being on its own. What is meant by ‘being on its own’ varies among philosophers. For example, it might mean the irrelevance (or even negative influence) of rational thought, moral values, or empirical evidence, when it comes to making fundamental decisions concerning one’s existence.
