John Dewey, "Ethics," a public lecture delivered at Columbia University in March, 1908, under the title of in a series of lectures on " Science, Philosophy, and Art."
To many timid, albeit sincere, souls of an earlier century, the decay of the doctrine that all true and worthful science is knowledge of final causes seemed fraught with danger to science and to morals. The rival conception of a wide open universe, a universe without bounds in time or space, without final limits of origin or destiny, a universe with the lid off, was a menace. We now face in moral science a similar crisis and like opportunity, as well as share in a like dreadful suspense.
You believe that reality is something objective, external, existing in its own right. You also believe that the nature of reality is self-evident. When you delude yourself into thinking that you see something, you assume that everyone else sees the same thing as you. But I tell you, Winston, that reality is not external. Reality exists in the human mind, and nowhere else. Not in the individual mind, which can make mistakes, and in any case soon perishes: only in the mind of the Party, which is collective and immortal. Whatever the Party holds to be the truth, is truth. It is impossible to see reality except by looking through the eyes of the Party. That is the fact that you have got to re-learn, Winston. It needs an act of self-destruction, an effort of the will. You must humble yourself before you can become sane. … Do you remember … writing in your diary, “Freedom is the freedom to say that two plus two make four”? … How many fingers am I holding up, Winston?
