“This theory argues that artists are useful to society because they are so sensitive. They are supersensitive. They keel over like canaries in coal mines filled with poison gas, long before more robust types realize that any danger is there.”

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".

Context: I do not understand this squeamishness about the use of gas. We have definitely adopted the position at the Peace Conference of arguing in favour of the retention of gas as a permanent method of warfare. It is sheer affectation to lacerate a man with the poisonous fragment of a bursting shell and to boggle at making his eyes water by means of lachrymatory gas. I am strongly in favour of using poisoned gas against uncivilised tribes. The moral effect should be so good that the loss of life should be reduced to a minimum. It is not necessary to use only the most deadly gases: gases can be used which cause great inconvenience and would spread a lively terror and yet would leave no serious permanent effects on most of those affected … We cannot, in any circumstances acquiesce to the non-utilisation of any weapons which are available to procure a speedy termination of the disorder which prevails on the frontier.
