All of it, unknown to us, exists within us - The Brown Book

"I am led to believe that everything we have seen, known, perceived, heard- even the trees of a deep forest- nay, even the disposition of the branches, the form of the leaves and the variety of the colours, the green tints and the light; the look of grains of sand at the edge of the sea, the unevenness of the crests of waves, whether agitated by a light breeze, or churned to foam by a storm, the multitude of human voices, of animal cries, and physical sounds, the melody and harmony of all songs, of all pieces of music, of all the concerts we have listened to, all of it, unknown to us, exists within us."
~Diderot
