“The dread of death, an instinct so unfailing in all animals, exists, not because existence is intrinsically so sweet, nor because annihilation is so distressing, but because this bugaboo has been an indispensable safeguard against the suicide of the life process. The expectation of post-mortem consciousness, so prevalent and so insistent among human beings, is a hope arising from the concussion of a desire and a fancy—the desire to persist just referred to, and the fancy or hallucination of a double which originated among savages from shadows, images, dreams, and the like.”

Tragedy and Triumph of Reason (1985)
Context: In medical science arguments are going on between behaviorists who perceive the function of brain as a multitude of simple and unconscious conditioned reflexes, and cognitivists who insist that humans sensing the surrounding world create its mental image which can be considered as memory of facts.
I do not intend to argue the essence of these processes, all the more so because it has been proved that both types of memory function in the brain. However, I am convinced that those who once saw a nuclear explosion or imagined the victims of Hiroshima and Nagasaki will forever maintain the mental picture of horror-stricken and dust-covered Earth, burned bodies of the dead and wounded and people slowly dying of radiation disease. Prompted by the sense of responsibility for the fortunes of the human race, Einstein addressed the following warning to his colleagues: "Since we, scientists, face the tragic lot of further increasing the murderous effectiveness of the means of destruction, it is our most solemn and noble duty to prevent the use of these weapons for the cruel ends they were designed to achieve".
