Lets break this down.
I appreciate the elaboration!
Firstly, “a priori” refers, within the context of transcendental investigations, as “that which is independent of any possible experience—viz., independent of empirical data”. “Knowledge” is just a justified, true belief (with truth being a version of correspondence theory) or, more generically, ~”having information which is accurate”. Knowledge
a priori, then, is when one has a true, justified belief about something which was not derived from empirical data (but, rather, the means by which our representative faculties intuit and cognize that data). The proposition “all bodies are extended” is universally true
for human experience and
a priori because the way we experience is in space (necessarily); and so this is
a priori known. Now, to your point, of which I concede, in order to acquire this
a priori knowledge one must have the self-reflective cognitive abilities to reason about their experience
transcendentally; and so a baby, I agree with you, necessarily does not have
a priori knowledge
even though they necessarily have an
a priori means of experiencing and the
a priori propositions are true of their experience as well (e.g., “all bodies are extended”). I was conflating, I think, that which is
a priori with that which is
a priori knowledge. E.g., intuition (necessarily) in space is
a priori but is not knowledge, but some propositions are true
a priori and are grounded in it (such as “the line drawn between two points is the shortest path” in geometry).
Secondly, I recognize that you reject the JTB theory of knowledge; so let me try to address yours as it relates hereto.
This is why in my knowledge theory I broke down what knowledge is into two camps.
When we ask “what is knowledge?”, we are expecting an monistic answer—e.g., “it is <…>”—and not a plurastic answer—e.g., “it is <…> and <…>”. You are saying that knowledge doesn’t have one fundamental identity but, instead, is two separate irreducible ones—namely “applicable” and “distinctive”.
This immediately incites the question: “if A is knowledge and B is knowledge, then aren’t they inheriting the same type of knowledge and, if so, thereby the question of ‘what is knowledge?’ is still unanswered?”. That’s like me saying knowledge is
a priori and
a posteriori. Ok. But we are asking “what is knowledge?”; so how did that answer the question?
Of course, you probably have an answer to this that I don’t remember….it has been a while (;
Briefly, I will also say, that your schema doesn’t negate the possibility of
a priori “knowledge” (in your sense of knowledge): it would be applicable knowledge, as the whole metaphysical endeavor of transcendental investigation would be applicable knowledge. The question becomes: “why don’t you think that we can apply
a priori knowledge without contradiction and reasonably to the forms of experience (viz., the necessary preconditions for the possibility of experience) given that we both agree that our experience is representational?”.
For example, we applicably know math through 'base 10'. But math can be in any base. Base 2, or binary, is the math we use for logic circuits.
The fact that we can do math in different bases does not negate that the same mathematical operations are occurring, and that they are synthetical,
a priori propositions.
The ability to think is not generally prescribed as 'knowledge'. Just like the ability to 'move my limbs' doesn't mean I know 'how to move them to walk'.
Correct. I was using the phrase too loosely.
It is purely an abstract thing that cannot be applicably known.
Ehhhh, then you cannot claim to know that there must be a thing-in-itself at all; or otherwise concede that you can know applicably, through experience, that if our experience is representational then there must be a thing-in-itself.
"The thing in itself" is a space alien
Then a thing-in-itself is not a concept which is purely logical—that was my only point on this note. It is referencing something concrete.
@Mww is denying this, and I thought so were you.
