Existence is a colossal risk. We can never know whether the way we choose to live is the right way. Anyone who realizes this fully, who makes himself consciously aware of it, is bound to feel anguish, according to Kierkegaard. Such subjective truths, supported by no objective evidence, are grounded on nothing. Literally. We thus come to know the nothingness of existence, the utter uncertainty that lies at its heart. Life is fundamentally tentative and elusive.
– Paul Strathern. (1997) Kierkegaard In 90 Minutes.
