Information and Wittgenstein
We should keep the self-evident in focus and refrain from descending into a philosophical nihilism. We are, after all, reasonable people, who are able to use our intelligence while communicating, and usually we understand each other quite well. The idea, that information is just a mental creation, evades the point: conceding that information is only a mental image, then what is that which determines, which amino acid comes to which place and is apparently contained in the sequence of the DNA triplets? If information is just an erroneous concept, then what is that what we receive as we ask at the airport, which gate to go for boarding? No, information does exist and we do use it day by day. Shannon has developed a method of repeatedly bifurcating a portion of N until finding that n of N that corresponds to the same n of which the sender encoded the search pattern for the receiver. The task lies not in negating the existence of the phaenomenon, but in proposing a more elegant and for biology useful explanation of the phaenomenon. The object of the game is still the same: identifying an n of N. The same situation is here with gravitation. We have a name for it, can measure it and integrate the concept - more or less seamlessly – into a general explanation. We just do not know, in an epistemological sense, what gravitation is. We have to take the normative power of the factual seriously and admit that we may have problems in the naming of an observed fact. This does not absolve us from the task of philosophers, that is, to try to understand and find good explanations for the facts that we perceive and to our thoughts about the perceptions and the facts. Adorno summarised the critique on Wittgenstein’s Tractatus, by saying, that W. apparently had not read the job description of a philosopher carefully enough: the task is not to investigate that what can be said exactly about a subject that is well known to all, but the task is to chisel away the border separating that what can be only felt and that what can be expressed understandably. This is the envy speaking of someone who suffered an Oedipus tragedy. Socrates said that the perpetrator of a crime suffers more than the victim, and post-war German philosophy understandably had no time to be interested in rules of exact speech. The grammar of the logical language, as a subject for serious study, was swept aside by historical cataclysms, although Wittgenstein begot Frege and Carnap who begot von Neumann and Boole who begot Shannon and Chomsky. That he in his later life put aside his epoch-generating work is completely in the consequence of what he had said. It is not disowning the ladder one has built to climb up a level of abstraction while doing a cartography of what exact talking really means, but a wise and truthful modesty of an artist who had fabricated a tool for a specific project. No self-respecting artist would want to be remembered for a practical tool he had assembled for a specific task. Roughly citing, he says so much: those who have understood what is written here, may throw [this book] away, like one has no need for a ladder after one has climbed a level. Having found out how the technical people speak (or should speak), he withdraws from that field, having clarified the rules of exact thinking, closing the subject in a conclusive fashion for about 4 generations, and acts in later life as if precognisant of Adorno’s words. Information is a connection of a symbol with a different symbol, if this state of the world can have a background and alternatives. If something can be otherwise, then the information is contained in the enumeration of the cases of being otherwise. By the use of computers, we can now create a whole topography and dramaturgy of exact speech. Had we the creativity of the Greeks, we would write a comedy, performed in public, by actors and narrators. The title could be: “All acting dutifully, striving their right place, catharsia are inevitable”. The best youth of Sparta, Athens etc. would compete for prominent places in diverse disciplines, but the results are not satisfactory, as the debate emerges, which of the disciplines are above the others. The wise people of Attica have come up with a perpetual compromise, its main points repeatedly summarised by the chorus, ruling that being constantly underway between both correct positions: p1 in discipline d1 and position p2 in discipline d2, is the divine sign of a noble character. If every athlete follows the same rule, imagine the traffic jams on the stage of the amphitheatre! The Greeks would have built an elaborate system of philosophy about the predictable collisions among actors representing athletes who have attended many of the concourses. They could have come up with specific names for typical results and would have named the agglomerations “elements” and “isotopes” that differ among each other on how many of the actors are glued together for lack of space to pass through, where too many paths cross, and on the form of the squeeze they constitute. They would no doubt have categorised and sub-classified and tabulated the inevitable melee that comes from having competing requirements to serve, a subject not far from their preoccupations with logic and predictable, consistent, rule observing behaviour by all, that by its very nature creates cooperation and conflict, destruction and growth. As long as the background and the alternatives to the statements, that describe what is the case, are conceptually discouraged or disallowed, it appears not very easy to use the term “information” in a consistent fashion. Information describes that what is not the case. (The DNA eliminates all the alternatives to that specific amino acid on that specific place; we have received information by knowing all those gates where we will not board the plane.) Thank you for this enjoyable year.
