Lewis Thomas said this quote

“ Perhaps it is in this respect that language differs most sharply from other biologic systems for communication. Ambiguity seems to be an essential, indispensable element for the transfer of information from one place to another by words, where matters of real importance are concerned. It is often necessary, for meaning to come through, that there be an almost vague sense of strangeness and askewness. Speechless animals and cells cannot do this. The specifically locked-on antigen at the surface of a lymphocyte does not send the cell off in search of something totally different; when a bee is tracking sugar by polarized light, observing the sun as though consulting his watch, he does not veer away to discover an unimaginable marvel of a flower. Only the human mind is designed to work in this way, programmed to drift away in the presence of locked-on information, straying from each point in a hunt for a better, different point.If it were not for the capacity for ambiguity, for the sensing of strangeness, the words in all languages provide, we would have no way of recognizing the layers of counterpoint in meaning, and we might be spending all our time sitting on stone fences, staring into the sun. To be sure, we would always have had some everyday use to make of the alphabet, and we might have reached the same capacity for small talk, but it is unlikely that we would have been able to evolve from words to Bach. The great thing about human language is that it prevents us from sticking to the matter at hand. ”
