This page is part of my self study project into philosophy. What is written are my own personal notes taken as a means of formalizing what I've read and/or learned. The information may not be accurate, as I may have took away the wrong points. Also the information could be basic or partial - as learning requires taking on small parts before getting deeper. The content may be a tad scatterbrain as well. Either way, it should be an interesting read and maybe you'll learn something with me.


Naive Realism: Our senses give us a direct awareness of objects as they really are.

Propositional Perception

Yields knowledge of two things, (a) what it is that we perceive, and (b) a property of it. OR perceiving that and to be.

Example: I see a door that is rectangular and red. OR I see that it is a door and it to be rectangular and red.

Make a note that propositional perception can include objectual perception: The content of my perception p includes both the proposition of p and also the objectual perception of the thing in question.

Objectual Perception

Yields knowledge of a property, but maybe not what it is you see. OR perceiving it to be.

Example: It's making a noise, but I'm not sure what it is. OR I hear it to be making a noise, even though I don't know what it is.

An objectual perception doesn't include a proposition perception because it perceives a property of an object.
