|Information, information theory: A character or a character combination contains information when it is clear to the recipient that this character or the character combination appears instead of another possible character or a possible character combination. The supply of possible characters determines to a part the probability of the occurrence of a character from this supply. In addition, the expected probability of the appearance of a character can be increased by already experienced experiences of regularities. The amount of information transmitted by a character depends on the improbability of the occurrence of the character._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

Marvin Minsky on Information - Dictionary of Arguments
Essential Information/distinctions/differences/environment/Artificial Intelligence/Minsky: Should we learn to exploit all the information we can get? No! There are good reasons not to notice too much, for every seemingly essential fact can generate a universe of useless, accidental, and even misleading facts.
Most differences are redundant. Most of the rest are accidents.
But how can we judge which facts are useful? On what basis can we decide which features are essential and which are merely accidents? Such questions can't be answered as they stand. They make no sense apart from how we want to use their answers. There is no single secret, magic trick to learning; we simply have to learn a large society of different ways to learn!_____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
