p.49 Properly speaking there are not signs, but only sign-functions... codes provide the rules which generate signs

p.64 this implication is true even though Napoleon is not an elephant, and it would be so even if Napoleon were an elephant, just as long as Paris is the capital of France.

p.65 Semiotics is mainly concerned with signs as social forces.

p.90 A chess game is a semiotic system with two planes and its pieces act as functives of a sign-function.

p.155 Semiotic judgments predicate of a given semiotic item what is already attributed to it by a code

p.158 Semiosis takes place among events, and many events happen that no code could have anticipated.

p.159 Let us call semiotic a judgment which predicates of a given content (one of more cultural units) the semantic markers already attributed to it by a previous code

p.187 In other words, if an astronomer discovers that small red elephants may be observed living on the moon, every time Capricorn enters into the orbit of Saturn, then his content-system will undoubtedly be upset [JLJ - just say no, Umberto...]

p.188 To propose a code is to propose a correlation.

p.191 It was said in 2.1. [JLJ - p.48, The sign-function] that a sign-function is the correlation between an expression and a content based on a conventionally established code (a system of correlational rules), and that codes provide the rules that generate sign-functions.

p.297 a theory of codes (which looks so independent from the actual world, naming its states through signs), demonstrates its heuristic and practical power, for it reveals, by showing the hidden interconnections of a given cultural system, the ways in which the labor of sign production can respect or betray the complexity of such a cultural network, thereby adapting it to... the human labor of transforming states of the world... This transformation cannot be performed without organizing such states of the world into semantic systems.
