"The present work reexamines the importance of the Danish philosopher and theologian S²ren Kierkegaard (1813-55). It argues that many of Kierkegaard's most controversial and influential ideas are more relevant than ever. Specifically, it shows how we can make good sense of ideas such as subjective truth, "the leap" into faith, and "the teleological suspension of the ethical." When properly understood, none of these ideas are as problematic as commentators have long assumed. This book shows that Kierkegaard offers a novel account of wholeheartedness that is relevant to discussions of personal identity, truth, ethics, and religion (particularly after Frankfurt, MacIntyre, C.

This account involves an original, adverbial theory of truth in which agents, rather than propositions, are the basic truth-bearers (Watts 2018). For Kierkegaard, wholeheartedness requires living truly by having a coherent personal identity (something he also describes as "purity of heart").
