Abstract

The relationship between knowledge and vision seems really consolidated. It started in ancient Greece and we can found its basis in Plato. The history of logos as reason and as western foundation of culture gives us enormous examples in terms of metaphors and approaches in the knowledge-vision relationship. «I see it» is like «I know it». However if we look at the basis of logos we find the deep meaning of gathering, composition, bond and bind (lèghein), so as to we could choose «to gather» as the best translation of logos (Hoffmann). My aim is to show how this key feature is represented by sounds. To think is to link information, memories and so on and the principal property of sound is union and merger. We can argue for a «sonorous thought» but in reality this property is simply the founding element of thought and reason. In fact if we analyse the limits of our knowledge (Kant, Plessner) we discover the incorrectness of knowledge-vision relationship – like the knowledge-discourse relationship. We should investigate this guideline as the recent research for Covid-19 vaccine has shown.
