The perpetual hesitation of the neurotic to launch out into life is readily explained by his desire to stand aside so as not to get involved in the dangerous struggle for existence. But anyone who refuses to experience life must stifle his desire to live- in other words, he must commit partial suicide.
Flight from life does not exempt us from the law of age and death. The neurotic who tries to wriggle out of the necessity of living wins nothing and only burdens himself with a constant foretaste of aging and dying, which must appear especially cruel on account of the total emptiness and meaninglessness of his life.
