|Semantics: Semantics is the field of linguistics, which deals with the meaning of expressions, words, parts of words, sentences or signs. Aids for ascertaining the meaning are investigations of the use and the determination of the truth value (true or false) of the statements, which can be determined from the linguistic or action-like utterances. Therefore, semantic questions are ultimately truth questions. See also truth, reference, meaning, sense, semiology, signs, symbols, syntax, pragmatics, linguistics._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

Semantics/Dennett: the first links are indeed so primitive that they can hardly be described as "semantic".
But as soon as a semantic allocation system is created (by a protein fragment combining itself with a nucleotide chain which it had helped before) the whole thing speeds up! Now a section of code can encode something new. New dimension to the assessment. Proteins are classified according to their catalytic properties.
semantics/syntax/Dennett: in the case of the genes there actually is an allocation between syntactic and semantic identity: a genetic language in which the meaning is preserved in broad terms across all species.
However, we must distinguish the two dimensions: In the Library of Babel we recognize a group of syntactic variants that are all part of the Moby Dick group, but due to their semantics, not due to syntactic similarity.
We recognize genes mainly due to similar phenotypic effects, for example, eyes or hemoglobin production.
Semantics/syntax/life/own/Dennett: the structural stability is not related to semantic information. This is only expressed in the translation product. Nature prefers certain letters - G and C are preferred, because they are most stable as replicators, and not because they come up most frequently in the genetic "words" - the preference, which is syntactic in the beginning, combines itself with a semantic imbalance: the logic of the code scheme results from purely physical and chemical conditions! - 222 I Beginnings so primitive that it can hardly be called semantic - as soon as semantic allocation system was created, the whole thing accelerated._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
