The discussion begins and continues not as a metaphysical cobweb but as a well reasoned statement based on a way of knowing which Camus holds is the only epistemology we have at our command. This heart within me I can feel, and I judge that it exists. This world I can touch, and I likewise judge that it exists. There ends all my knowledge, and the rest is construction. With these as the basic certainties of the human condition, Camus argues that there is no meaning to life.
Life has no absolute meaning.
Between this yearning for meaning and eternal verities and the actual condition of the universe there is a gap that can never be filled. The confrontation of the irrational, longing human heart and the indifferent universe brings about the notion of the absurd. The absurd is born of this confrontation between the human need and the unreasonable silence of the world. People must realize that the feeling of the absurd exists and can happen to them at any time. The absurd person must demand to live solely with what is known and to bring in nothing that is not certain.
