Existence appears not only nonsensical but monstrous and absurd, and the search for any meaning in life completely futile and, a priori, doomed to failure. People are seen as thrown into this world without any choice as to whether, where, when, and to whom they are to be born. The only certainty in life appears to be the fact that its duration is limited and that it will end. The fact of human mortality and the impermanence of all things is seen as Damocles’ sword hanging over us during every minute of our lives and annihilating any hope that anything has meaning.
Another important dimension of the “no exit” situation is the feeling of pervading insanity; subjects typically feel that they have lost all mental control and become permanently psychotic, or that they have gained the ultimate insight into the absurdity of the universe and will never be able to return to the merciful self-deception that is a necessary prerequisite f0r sanity.
