Søren Kierkegaard is born in Copenhagen, Denmark. A philosopher who focuses on the nature of human freedom in an uncertain world, Soren Kierkegaard will become him one of the founders of the modern philosophy of existentialism, even though he did not use that label for himself.
An important aspect of Kierkegaard's philosophy will be his distinction between objective truths, which include the correspondence between facts and beliefs, and subjective truths, which include our passionate commitment to ideas and beliefs.
Kierkegaard will argue that religion is characterized not by objective truths, but subjective truths: religion is made meaningful and relevant by our passionate commitment to what we believe and what we want out of life. Such commitment is self-validating and impervious to external, skeptical critique. It is either something we have or something we lack, but not something which can be justified to others through reference to objective truths.
