In philosophy, these properties are sometimes also called “qualia”: the redness of red, the pang of jealousy, the sharp pain or dull throb of a toothache. For an organism to be conscious, it has to have some kind of phenomenology for itself. Any kind of experience—any phenomenological property—counts as much as any other. Wherever there is experience, there is phenomenology; and wherever there is phenomenology, there is consciousness.
