studies in indirect communication vol. xxxi: otherness part one

Our speech, that is, all our utterances … is filled with others' words, varying degrees of otherness or varying degrees of 'our-own-ness,' varying degrees of awareness and detachment. These words of others carry with them their own expression, their own evaluative tone, which we assimilate, rework, and re-accentuate… Thus the expressiveness of individual words is not inherent in the words themselves as units of language, nor does it issue directly from the meaning of these words: it is either typical generic expression or it is an echo of another's individual expression, which makes the word, as it were, representative of another's whole utterance from a particular evaluative position.
