TIL: Tautological - an argument which repeats an assertion using different phrasing



This is one of my favorite words. I almost never find a way to correctly work it into a sentence, so was happy I managed to do so here.


I remember learning this in high-school as part of propositional logic, and it was essentially described "the opposite of a contradiction":

Is the teaching of propositional logic common in the US?


I did not learn propositional logic until I was in college.


To be fair, the school I went to was very particular, as it ran by the same university that ran the college I went to. In a way, a lot of the subjects we took early on were preparing us for college.


I looked this up as well! Hah!
