To everyone battling a difficulty or under attack right now, smile, keep your head up, keep moving and stay positive, you'll get through it.

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.

Ever since I was young I enjoyed solving puzzles and having the pleasure to see the bigger picture afterwards. But even after all that, I found that life could be the most challenging puzzle we have to face. It's one of those things that even if you have all the pieces and could see the whole picture, it still takes time and patience to solve it. At times, we feel more at ease not knowing the whole picture, not knowing the whole level of difficulty or number of pieces that we're missing, but just building up one piece at a time. The problem with this approach is that the only clues that we have for matching two pieces are the shape and a small glimpse of the image. We so often find comfort in building up the corners and the borders but very rarely do we adventure in the middle of the puzzle. We'd rather work little by little holding on to our safe border and only move towards the center when the pieces are still in touch with our borders or roots. On the other hand, you could be one of those people that just jumps in the middle and builds up on every piece you have in order to get small portions of the truth of the bigger picture every now and then. Not having your borders or corners in place might mean that you don't need to know your limits in order to realize that the puzzle will one day come to an end. Nevertheless, every piece is equally important and it gets handed to you at a time where you have at least some matching piece. That doesn't mean you should only focus on one point or piece and limit your possible connections. Spread out and you will find even more connections. The truth of the puzzle information comes in different shapes and colors but in the end it's all connected. Information might be divided, spread out in different areas, different people, different experiences. What's important to remember is that every piece is meant for you. You might throw it on the side now and use it later, but it will forever remain a part of your bigger picture. Work on your puzzle, with patience and care in moving forward and with a hopeful spirit that it will all work out in the end for your highest good!
