"We found the unit that reflects the unity of thinking and speech in the meaning of the word. As we have tried to show, word meaning is a unity of both processes that cannot be further decomposed. That is, we cannot say that word meaning is a phenomenon of either speech or thinking."
"the connection between thought and word is neither inherent or primal. This connection emerges, changes, and grows with the development of thought and word."
"...it would be incorrect to represent thinking and speech as processes that are externally related to one another, as two independent forces moving and acting in parallel with one another or intersecting at specific points and interacting mechanically. The absence of a primal connection between thought and word does not imply that this connection can arise only as an external connection between two fundamentally heterogeneous forms of the activity of consciousness."
"The discovery that word meaning changes and develops is our new and fundamental contribution to the theory of thinking and speech. It is our major discovery, a discovery that has allowed us to overcome the postulate of constancy and unchangableness of word meaning which has provided the foundation for previous theories of thinking and speech."
"The nature of meaning is revealed in generalization. The basic and central feature of any word ‘is generalization. All words generalize."
"It is important to emphasize, however, that the fact that the internal nature of word meaning changes implies that the relationship of thought to word changes as well."
"The movement of thinking from thought to word is a developmental process. Thought is not expressed but completed in the word."
"Any thought strives to unify, to establish a relationship between one thing and another, Any thought has movement. It unfolds. It fulfills some function or resolves some task. This flow of thought is realized as an internal movement through several planes, as a transition from thought to word and from word to thought. Thus, the first task in an analysis of the relationship of thought and word as a movement from thought to word is to analyze the phases that compose this movement, to differentiate the planes through which thought passes as it becomes embodied in the word."
"The structure of speech is not a simple mirror image of the structure of thought. it cannot, therefore, be placed on thought like clothes off a rack. Speech does not merely serve as the expression of developed thought. Thought is restructured as it is transformed into speech. It is not expressed but completed in the word."
"The partitioning of speech into semantics and phonology is not given at the outset. It arises in the course of development. The child must differentiate these two aspects of speech. He must become consciously aware of the different nature of each to permit the gradual descension that is presupposed in the living process of meaningful speech."
"Thought imprints a logical emphasis on one word in a phrase, isolating the psychological predicate. Without this, no phrase would be comprehensible."
