Carlisle, Clare. "Kierkegaard's World, Part 2: The Truth of Knowledge and the Truth of Life." GUARDIAN March 22, 2010

One of Kierkegaard's most influential ideas is his distinction between two kinds of truth. Sometimes he describes these as "objective" and "subjective" truth; sometimes as truth that is known, and truth that is lived. According to Kierkegaard, it is the lived, subjective kind of truth that is most important to each existing human being. Implicit in this claim is a critique of traditional philosophy, for most philosophers – in spite of disagreements about how to define truth, how much of it can be known, and how best to attain it – have thought that truth, if it is possessed at all, is possessed in the form of knowledge. Kierkegaard is not particularly interested in philosophical debates about whether we really know that the things we perceive exist, or whether we really know that today is Monday. With regard to the truth as knowledge, Kierkegaard tends to emphasise the absence of certainty: for example, he argues that the historical life of Jesus can only be a matter of belief, not knowledge, and he regards the Christian doctrine of the incarnation as a paradox that human reason cannot grasp. But what is most important, in his view, is the way each individual relates themselves to these beliefs, or indeed to any other beliefs, values or ideals. What matters is how beliefs are lived, from day to day and even from moment to moment. Kierkegaard focuses on the question of what it means to be true, or to exist truthfully. . . .
