Luke Monahan Posted almost 2 years ago Materialists and those who think humans evolved from animals are irrational. Explaining my thoughts on free will can be difficult, I don't always have the right words to be understood correctly but let’s see how it goes. Predicting the outcome of a decision requires three things; you must know all the variables, you must know all the rules and reality itself must be absolutely deterministic. My very amateur understanding of quantum physics is that the Heisenberg uncertainty principle disallows our knowing all variables and Bells theorem suggests that quantum effects cannot be explained with local variables and determinism cannot be absolute. If free will is to exists, it's probably expressed somehow on the quantum level. I'm going to borrow from a previous post of mine now; There are conceptual problems with the idea of free will; The act of making a decision is one which is made, consciously or otherwise, by placing all the known variables into an equation defined by your value system and determining the best conceptual path. This process is very mechanical and predicable, if you know the variables and the equation, you automatically know the outcome. If free will does exist it means that a decision must be made in the absence of knowledge, values and analysis. It would be the ability to make a choice when you don't even know that there is one to be made. (otherwise it is predictable and not true free will) Free will is paradoxically nonsensical but at the same time an individual’s experienced existence or even existence itself cannot be explained with a "turtles all the way down" endless causal chain of events. (I don't see absolute determinism as a viable alternative explanation).
