People can know facts about perceptions {fact-perception, epistemology}.
People can perceive without knowing {thing-perception, epistemology}.
People cannot distinguish hallucination and perception {argument from illusion, epistemology}, except later by comparison and memory.
Brains can know symbolic representations {phenomenon} {phenomena, epistemology} of physical or non-physical things. Phenomena include conscious and non-conscious mental states. Phenomena are perspectives on objects and events. Perspectives indicate object or event essence.
types
Phenomena are sights, sounds, smells, tastes, touches, feelings, and limb positions. They are daydreams, talks with self, recollections, and ideas. They are pains, tickles, hunger, thirst, anger, joy, hatred, embarrassment, lust, astonishment, pride, anxiety, regret, ironic detachment, rue, awe, and calm.
consciousness
Consciousness is experiencing phenomena and qualia, not objects themselves. Consciousness has no intentions or beliefs but just is or has phenomena. All humans appear to have same awareness and consciousness and go through same consciousness-development stages. Perhaps, animals have some consciousness, because they can analyze images to do things that people can do.
Sense information {sense-data} {sense-datum, epistemology} can be about physical objects. Brain processes sense-data to make ideas and categories. Brain can forget sense-data. Perhaps, inner, non-physical, unified images are available to consciousness. Sense-data do not necessarily represent reality.
Knowledge of appearances requires consciousness of appearance {sense-datum fallacy}.
Senses only know appearances {veil of perception}, not reality.
People unconsciously use assumptions, theories, and concepts {paradigm, perception}| {indexical term} about subjects or objects. Indexical terms can refer to other objects, depending on context, so context sets indexes. Properties can exist without paradigms, so paradigms cannot define properties. To specify paradigms requires specifying a property that makes the paradigm, because paradigms have more than one property, but this is circular reasoning.
Secondary qualities do not necessarily associate with objects {contingent attachment}.
Paradigms can refer to something, sometimes by pointing {ostension}.
