The logical Cartesian Circle
Validity 1
P1- A>B
P2- A
S1- B
H/
P1 & P2>S1 is a mere rephrasing
The argument is circular. The only conclusion that can be reached from the evidence is that the evidence is
Same effect with Cartesian circle- beginning with the unsuspended idea of God (although he said it was suspended), we find the idea of perfection (A) which is evidence of God (B) as he must have created the idea of perfection. Therefore, if the idea of perfection exists, so does God.
Validity 2
P1- A
P2- A>B
P3- A
S1 B
H/
S1 rests entirely on P1, and could be reversed
Validity 3
P1- B
P2- B>A
P3- B
S1- A
T/ the argument, as in Validity 1, only concludes what we already know. H/ since w/ Descartes, we can't know anything (apart from cogito ergo sum 'I am aware of my thinking, T/ I am existing), that we can reverse what has been said and prove that S1 in both Validity 1 and 2 is only based on assumed prior knowledge, the conclusion is epistemologically invalid.




H/ 'However' B/ 'Because' w/ 'with'
