Quote:"Truth" should never be "given".
The truth of the premise is always assumed in formal logic. Hence,a logical proposition is always expressed "IF A-----"
Logic guarantees truth if and only if the premise has been proved to be true--and there's the rub. I reject the the notion that proof can be determined by reason alone. Believers disagree and try to evade the burden of proof by the use of special pleading and a host of other logical fallacies.
