The humanitarian philosophies that have been developed (sometimes under some religious banner and invariably in the face of religious opposition) are human inventions, as the name implies - and our species deserves the credit. I am a devout atheist - nothing else makes any sense to me and I must admit to being bewildered by those, who in the face of what appears so obvious, still believe in a mystical creator. However I can see that the promise of infinite immortality is a more palatable proposition than the absolute certainty of finite mortality which those of us who are subject to free thought (as opposed to free will) have to look forward to and many may not have the strength of character to accept it.Thus I am a supporter of Amnesty International, a humanist and an atheist. I believe in a secular, democratic society in which women and men have total equality, and individuals can pursue their lives as they wish, free of constraints - religious or otherwise. I feel that the difficult ethical and social problems which invariably arise must be solved, as best they can, by discussion and am opposed to the crude simplistic application of dogmatic rules invented in past millennia and ascribed to a plethora of mystical creators - or the latest invention; a single creator masquerading under a plethora of pseudonyms. Organisations which seek political influence by co-ordinated effort disturb me and thus I believe religious and related pressure groups which operate in this way are acting antidemocratically and should play no part in politics. I also have problems with those who preach racist and related ideologies which seem almost indistinguishable from nationalism, patriotism and religious conviction.
The difficulties connected with my criterion of demarcation (D) are important, but must not be exaggerated. It is vague, since it is a methodological rule, and since the demarcation between science and nonscience is vague. But it is more than sharp enough to make a distinction between many physical theories on the one hand, and metaphysical theories, such as psychoanalysis, or Marxism (in its present form), on the other. This is, of course, one of my main theses; and nobody who has not understood it can be said to have understood my theory.The situation with Marxism is, incidentally, very different from that with psychoanalysis. Marxism was once a scientific theory: it predicted that capitalism would lead to increasing misery and, through a more or less mild revolution, to socialism; it predicted that this would happen first in the technically highest developed countries; and it predicted that the technical evolution of the 'means of production' would lead to social, political, and ideological developments, rather than the other way round.But the (so-called) socialist revolution came first in one of the technically backward countries. And instead of the means of production producing a new ideology, it was Lenin's and Stalin's ideology that Russia must push forward with its industrialization ('Socialism is dictatorship of the proletariat plus electrification') which promoted the new development of the means of production.Thus one might say that Marxism was once a science, but one which was refuted by some of the facts which happened to clash with its predictions (I have here mentioned just a few of these facts).However, Marxism is no longer a science; for it broke the methodological rule that we must accept falsification, and it immunized itself against the most blatant refutations of its predictions. Ever since then, it can be described only as nonscience—as a metaphysical dream, if you like, married to a cruel reality.Psychoanalysis is a very different case. It is an interesting psychological metaphysics (and no doubt there is some truth in it, as there is so often in metaphysical ideas), but it never was a science. There may be lots of people who are Freudian or Adlerian cases: Freud himself was clearly a Freudian case, and Adler an Adlerian case. But what prevents their theories from being scientific in the sense here described is, very simply, that they do not exclude any physically possible human behaviour. Whatever anybody may do is, in principle, explicable in Freudian or Adlerian terms. (Adler's break with Freud was more Adlerian than Freudian, but Freud never looked on it as a refutation of his theory.)The point is very clear. Neither Freud nor Adler excludes any particular person's acting in any particular way, whatever the outward circumstances. Whether a man sacrificed his life to rescue a drowning, child (a case of sublimation) or whether he murdered the child by drowning him (a case of repression) could not possibly be predicted or excluded by Freud's theory; the theory was compatible with everything that could happen—even without any special immunization treatment.Thus while Marxism became non-scientific by its adoption of an immunizing strategy, psychoanalysis was immune to start with, and remained so. In contrast, most physical theories are pretty free of immunizing tactics and highly falsifiable to start with. As a rule, they exclude an infinity of conceivable possibilities.
