  A formal theory of meaning (the process of knowledge accumulation) as
multiplicative chaos is proposed. The epistemological process is understood as
the process of subjective extraction of some knowledge from the incoming
information. The concepts of nonsense are introduced as a meaning that has a
minimum value equal to one and the level of intelligence as a geometric mean of
the cumulative meaning. The thesis of the multiplicativity of meaning, its
polymorphism is substantiated, and numerous examples from world history are
provided. By analogy with classical thermodynamics, three laws of
thermodynamics of meaning are postulated. Estimates of the cumulative meaning
when the comprehension of information (multiplicative cascade) is a random
process with given statistical characteristics are carried out.
