General Discussion / Re: Philosophy: Is "chair" an opinion?
« on: September 05, 2017, 11:15:13 pm »* disagreements about logic (my baby brother says that 1+1=11)I disagree with this category. By its very definition logic is not disputable. Take your example, for instance. 1+1=11 is not an opinion; it is an utter and complete falsehood. The thing about mathematics is that everything is very black and white -- given the same fundamental set of axioms, everything is either true or false. If you can present a mathematical proof of a statement, that statement is completely and unconditionally true. The same arguments can be applied to logic (which in my opinion falls into the category of mathematics).
