It is useful to the historian, among others, to be able to see the commonest forms of different phenomena, whether phonetic, morphological or other, and how language lives, carries on and changes over time.

---

A linguistic system is a series of differences of sound combined with a series of differences of ideas.

---

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.

---

It is only since linguistics has become more aware of its object of study, i.e. perceives the whole extent of it, that it is evident that this science can make a contribution to a range of studies that will be of interest to almost anyone.

---

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.

---

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.

---

Without language, thought is a vague, uncharted nebula.

---

Psychologically our thought-apart from its expression in words-is only a shapeless and indistinct mass.
