p.3 It is extremely difficult to speak about meaning and to say something meaningful about it... Unfortunately the expression "meaningless" is not meaningless: it is even at the origin of philosophies of the absurd.

p.7 Human beings live in a signifying world. For them the problem of meaning does not arise; meaning is a given: it imposes itself as an obvious fact, as an entirely natural "feeling of understanding."

p.8 the semiotic description of signification consists in constructing an adequate artificial language

p.9 meaning, in order to manifest itself, can sometimes take the form of a system, sometimes that of a process, while remaining whole... It accounts for the fact that an activity can be transcribed both as a processual algorithm and transcoded as a systematic and virtual know-how. [JLJ - Human beings, by their nature, execute a kind of internal "script" which attempts to extract meaning from impressions in the course of determining how to "go on". Meaning cannot be defined precisely because the extraction of degrees of meaning from the symbolic world is essentially what we do.]

p.18 Relevance is thus one of the main postulates of taxonomic doing... The concept of relevance is thus the basis for the procedures we call reduction. These require that nonnecessary elements be transferred from one level of the analysis to another, lower, one.
