Q

DOGMA + ACADEMIC SKEPTIC

A

The dogmatic thought stands for the claim that knowledge is possible, while the academic skeptics hold that knowledge is impossible, that we cannot know things.

They argue that knowledge requires that we eliminate all doubt.
They did not doubt the existence of truth in itself, only our capacities for obtaining it.

Academics argue for the claim that nothing can be known at all, they argue negatively for the dogmatic claim.

  • formula
  • assignment
  • premise
  • where, C + ~SK
A

(X) (Y) ((X>Y)&Jsx )>Jsy)

where x & y are propositions, s is a subject and J is a relation such that jsx stand for s is justified in believing X.
For all propositions x & y, if x entails y, and s is justified in believing x then s is justified in believing y

CP1) If I am justified in believing that C then I am justified in believing that, ~sk.

CP2) I am not justified on believing that ~sk

C) Therefore I  am not justified in believing that C

Where C is “ there is a chair that I am sitting on” and sk is “ I am a world that appears identical to this one, but the chair does not exist”
