Now, I've seen propositional logic being expressed by way of formulas before but have never delved into it (formulas scare me), particularly since different sources use different notation.
I was wondering if someone could help me interpret read the formulas in points 3(a),(b) and 4(a),(b) - https://faculty.washington.edu/smcohen/320/heracli.htm
I believe the formula in point 2 reads - for all F, F is identical to its opposite F.
Any advice on learning this form of notation would be greatly appreciated.
Yeah, I understand your confusion. If Heraclitus says "hot" is identical to "not cold" you have to forget about lukewarm, which is also "not cold". So much for that kind of shit identity.
