In absurdist philosophy, the Absurd arises out of the fundamental disharmony between the individual's search for meaning and the apparent meaninglessness of the universe. As beings looking for meaning in a meaningless world, humans have three ways of resolving the dilemma. Kierkegaard and Camus describe the solutions in their works, The Sickness Unto Death (1849) and The Myth of Sisyphus (1942):

* Suicide (or, "escaping existence"): a solution in which a person simply ends one's own life. Both Kierkegaard and Camus dismiss the viability of this option. Camus states that it does not counter the Absurd, but only becomes more absurd, to end one's own existence.

* Religious, spiritual, or abstract belief in a transcendent realm, being, or idea: a solution in which one believes in the existence of a reality that is beyond the Absurd, and, as such, has meaning. Kierkegaard stated that a belief in anything beyond the Absurd requires a non-rational but perhaps necessary religious acceptance in such an intangible and empirically unprovable thing (now commonly referred to as a "leap of faith"). However, Camus regarded this solution, and others, as "philosophical suicide".

* Acceptance of the Absurd: a solution in which one accepts the Absurd and continues to live in spite of it. Camus endorsed this solution, believing that by accepting the Absurd, one can achieve absolute freedom, and that by recognizing no religious or other moral constraints and by revolting against the Absurd while simultaneously accepting it as unstoppable, one could possibly be content from the personal meaning constructed in the process. Kierkegaard, on the other hand, regarded this solution as "demoniac madness": "He rages most of all at the thought that eternity might get it into its head to take his misery from him!
