If you can't say it simply and clearly, keep quiet, and keep working on it till you can. - Karl Popper

Is there a meaning in history? I do not wish to enter here into the problem of the meaning of ‘meaning’; I take it for granted that most people know with sufficient clarity what they mean when they speak of the ‘meaning of history’ or of the ‘meaning or purpose of life’10. And in this sense, in the sense in which the question of the meaning of history is asked, I answer: History has no meaning. In order to give reasons for this opinion, I must first say something about that ‘history’ which people have in mind when they ask whether it has meaning. So far, I have myself spoken about ‘history’ as if it did not need any explanation. That is no longer possible; for I wish to make it clear that ‘history’ in the sense in which most people speak of it simply does not exist; and this is at least one reason why I say that it has no meaning. How do most people come to use the term ‘history’? (I mean ‘history’ in the sense in which we say of a book that it is about the history of Europe — not in the sense in which we say that it is a history of Europe.) They learn about it in school and at the University. They read books about it. They see what is treated in the books under the name ‘history of the world’ or ‘the history of mankind’, and they get used to looking upon it as a more or less definite series of facts. And these facts constitute, they believe, the history of mankind. But we have already seen that the realm of facts is infinitely rich, and that there must be selection. According to our interests, we could, for instance, write about the history of art; or of language; or of feeding habits; or of typhus fever (see Zinsser’s Rats, Lice, and History). Certainly, none of these is the history of mankind (nor all of them taken together). What people have in mind when they speak of the history of mankind is, rather, the history of the Egyptian, Babylonian, Persian, Macedonian, and Roman empires, and so on, down to our own day. In other words: They speak about the history of m

One of the ideas I had discussed in The Poverty of Historicism was the influence of a prediction upon the event predicted. I had called this the "Oedipus effect", because the oracle played a most important role in the sequence of events which led to the fulfilment of its prophecy. ... For a time I thought that the existence of the Oedipus effect distinguished the social from the natural sciences. But in biology, too—even in molecular biology—expectations often play a role in bringing about what has been expected.

Conjecture or hypothesis must come before observation or perception: we have inborn expectations; we have latent inborn knowledge, in the form of latent expectations, to be activated by a stimuli to which we react as a rule while engaged in active exploration. All learning is a modification (it may be a refutation)of some prior knowledge and thus, in the last analysis, of some inborn knowledge.
