Ah, but "logic" is more akin to math or philosophy. Like math it often relies on axioms, and the outcome can vary dependent upon the axioms. For example, a mathematical model of a 2-dimensional universe can be "logical". And you can throw all the numbers you like at it and it'll still work (as long as you don't suck at math). But it doesn't have any bearing on our reality. Same if we take the philosophical approach, as philosophical arguments for and against (insert whatever you like here) will usually claim to be "logical". Except that neither side in a philosophical argument can really prove their opinions are the "right" ones. And those arguments don't necessarily fall because of the opposing philosophical position, but often because they break their own rules (such as the creationist "everything must have a cause" argument).Science isn't the only tool for falsifiying. There's logic. But the Dude is too dumb and arrogant to understand this point.
So if you're gonna give me some math, then gimme some math. Otherwise if you're gonna take the philosophy route, then I remind you that philosophy is to science as what ornithology is to birds. In other words, outside one's own personal subjectivity, philosophy is bollox.(shrug)
