How Do You Do Science Without Free Will? From my perspective, by linguistic convention I should at least say that "you have a choice as to what you eat" with respect to the imprecise situation you put forward. — sime
Yes, I have a choice. I've tried to make the situation precise as we need. Yes, it is idealised and perhaps unrealistic, but I'm trying to keep things simple.
What I'm suggesting is that there are two kinds of choices, those that are determined and those that are not. StreetlightX has suggested that just because a decision is determined by a process of deliberation, does not make that decision any less of a choice, nor does it imply a lack of freedom. And I agree there are choices like that, and that they are correctly called choices. He goes on to say that free will (perhaps in the sense of an undetermined choice) is a pernicious relic that we do not need any more. I'm suggesting that there are, at least in principle, undetermined choices. These are choices where we don't mind which alternative we choose. My cream cake example is one. But perhaps these situations never actually arise in reality, just as perfect circles never occur. Perhaps there is never, actually, a choice about which someone is wholly indifferent to the result. But even if that's the case, the concept is still a useful one - there are decisions that are more or less arbitrary, and these are approaching instances of free will.
Supposing you now reveal that you have an allergy for cream. Then i might now say "it appears that you don't have that much of a choice relative to my previous understanding, given your newly admitted allergy for cream"
The question is, does there exist an absolutely precise and exhaustively describable circumstance that you can describe, or that I can observe, under which I am at least permitted to say without fear of controversy, that you have absolutely no choice but to take one of the presented options? — sime
Assume I've given all the relevant information, for the sake of discussion. In the scenario, I am very hungry and want one of the cakes. I have a choice whether to eat a cake or not (according to street). The deliberation involves feelings of hunger and desire (nothing else). I eat one of the cakes. Not eating one of the cakes in this circumstance would involve other factors which I have not given (i.e. madness, cream allergy, diabetes, obesity, hallucination etc). My choice to eat one of the cakes is highly determined.
However I really don't mind at all which cake I eat. I make a choice and eat the jam doughnut. The question is, is this decision determined or not? I don't think it is. I think it is a free arbitrary choice. Is this even possible do you think? It's logically possible. Is it metaphysically possible? Physically possible? Psychologically possible? Or is there always a determinant?
Regarding vagueness, indulge me with this idealised scenario, which I grant might be impossible to actually exist. Just as the non-existence of perfect circles does not stop us calculating using assumptions of perfect circles when designing machines, I want to contrast the concepts of free and determined choice by using an idealised scenario.
