hello /lit/
can you rec me some decent positions on logics as a tool of philosophical analysis?
>>
>>8290023
dunno, get a introductory logic textbook perhaps
>>
P1) Assume that laws of logic are true (AIP).
P2) All propositions are either true or false (LEM, P1).
P3) The proposition "This statement is false" is neither true nor false.
P4) There exists a proposition that is neither true nor false (P3, EQ).
P5) It is not the case that all propositions are true or false (P4 CQ).
P6) It both is and is not the case that all propositions are true or false (P2, P5 Conj).
P7) Therefore the laws of logic are not true (1-6 IP).

>>8290023
Can you specify a bit more what you are interested in and maybe say what your background in philosophy is?
>>
>>8290157
What is the statement that isn't true or false?
>>
Nah
>>
>>8290225
I think he's just saying that sentences that ascribe truth values to themselves aren't assigned truth values. It's to avoid liar paradoxes.
>>
>>8290225
"This statement is false"
>>8290236
I'm also saying that the laws of logic are contradictory. (Because skepticism is bae.)
>>
>>8290448

Alternatively, Godel covered this well.

>>8290448

Sometimes I wish I was 17 too

>>8290456
