" One thus arrives at a curious conception of thought. Thought has no real, concrete existence, accessible to immediate consciousness, since the datum of introspection is the image. It has no universality in act, because, if it were so, one should be able to grasp it directly. But it is a potential universality that one derives from the fact that a word can be accompanied by very different images. "

― Jean-Paul Sartre , The Imaginary
