We have talked about the senses and their relation. There are relations among senses that happen on an ìinternalî level, which are in fact a way of defining the place where they  merge. And there is a word, "synesthesia", that intends to refer to it, although itís poetic and very well intended. One would suppose, for example, that an image would suggest or would unleash the internal perception of a sound or a word, a scent. This would occur in the ìinternalî senses. And of course it happens, although for it to happen the concurrence of imagination is necessary. We were talking about desire. This is a fundamental tool, since from experience, sensorial knowledge can be generated or reproduced. This way, still poetically, one can smell a sound or hear an image, touch a scent, see a... (what is the unit of touch?). Although for now, more so than synesthesia, it would be necessary to speak about a permanent anesthesia and a general tendency to approach audible objects with visual attitude.
