Obviously I borrowed it as a response to the casuality dilemma you borrowed. Just throwing one theory against another. At the end of the day the scientific theorys of today do not rest on absolute determinism as in the case of QM, which falsifies the premise you put up. The then "what if" questions are mere hypothetical and can be responded by imagining a 100 other "what if" scenarios. Even if you say that you were determined to speak against freewill, the truth of statement is not yet established since determination implies you were forced to say so. So if you havent established the truth of the statement then you can't say you were forced to say so, which rests upon the truthness of your statement. Your goal is to prove determination. You instead presume determination along the way. Secondly my point was on regards to tasting freewill. When you speak about freewill, we have to know what freewill is in the first place. Now it is because we have tasted freewill that we know it. Its impossible that you could be forced and yet be aware of what exactly freewill is. So the mere fact that we discuss freewill knowingly is proof of its existance because a forced object would not be aware of what exactly freewill is. Just as a blind man wouldnt know color until he tasted color similarly a forced man wouldnt know freewill until he tasted freewill.
