It is one of the aims of linguistics to define itself, to recognise what belongs within its domain. In those cases where it relies upon psychology, it will do so indirectly, remaining independent.

Any psychology of sign systems will be part of social psychology - that is to say, will be exclusively social; it will involve the same psychology as is applicable in the case of languages.

A language presupposes that all the individual users possess the organs.

The ultimate law of language is, dare we say, that nothing can ever reside in a single term. This is a direct consequence of the fact that linguistic signs are unrelated to what they designate and that, therefore, 'a' cannot designate anything without the the aid of 'b' and vice versa, or, in other words, that both have value only by the difference between them.

Of all social institutions language is least amenable to initiative. It blends with the life of society, and the latter, inert by nature, is a prime conservative force.

Outside speech, the association that is made in the memory between words having something in common creates different groups, series, families, within which very diverse relations obtain but belonging to a single category: these are associative relations.

Language furnishes the best proof that a law accepted by a community is a thing that is tolerated and not a rule to which all freely consent.
