" It looked like a colour, but also... like a bruise or a secretion, like an oozing-and something else, an odour, for example, it melted into the odour of wet earth, warm, moist wood, into a black odour that spread like varnish over this sensitive wood, in a flavour of chewed, sweet fibre. I did not simply see this black: sight is an abstract invention, a simplified idea, one of man's ideas. That black, amorphous, weakly presence, far surpassed sight, smell and taste. But this richness was lost in confusion and finally was no more because it was too much. "
― Jean-Paul Sartre , Nausea
