“For two things both to believe that snow is white, they need not to be physically similar in any specifiable way, but they must both be in a "functional" condition or state specifiable in the most functional language; they must share a Turing machine description according to which they are both in some particular logical state (which is roughly like two different computers having the same program and being in the same "place" in the program). … it is a type functionalism—each mental type is identifiable as a functional type in the language of Turing machine description.”

“In 1936 the notion of a computable function was clarified by Turing, and he showed the existence of universal computers that, with an appropriate program, could compute anything computed by any other computer. […] In some subconscious sense even the sales departments of computer manufacturers are aware of this, and they do not advertise magic instructions that cannot be simulated on competitors machines, but only that their machines are faster, cheaper, have more memory, or are easier to program.”

“Computers and robots replace humans in the exercise of mental functions in the same way as mechanical power replaced them in the performance of physical tasks. As time goes on, more and more complex mental functions will be performed by machines. Any worker who now performs his task by following specific instructions can, in principle, be replaced by a machine. This means that the role of humans as the most important factor of production is bound to diminish—in the same way that the role of horses in agricultural production was first diminished and then eliminated by the introduction of tractors.”

“The development of modern science is marked by a pronounced tendency toward indeterminism. A somewhat brutal description of this tendency may be states as follows. In relation to some phenomena, instead of trying to establish a (deterministic) functional relationship between a variable y, and some other variables x1, x2, …, xn, we try to build a (stochastic or probabilistic) model of these phenomena, predicting frequencies with which, in specified conditions, the same variable y will assume all of its possible values.”

“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.”

Yevgeniy Chazov (1929) Russian physician

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".
