C. S. Peirce is the name of another philosopher that Deleuze critiques like Bergson with respect to his classification of images and signs. Pierce develops the terms "reume" and "dicisign" to differentiate an image becoming liquid from an image that solidifies. Camera-consciousness is the term used to describe a state of perception that is facilitated by the liquid perception that is the ability to transition from flowing perception to material determination. Peirce names this image "reume," which is becoming liquid and contrasts it with "dicisign" which is a frame that isolates and solidifies an image.
