The idea that free will and determinism are contradictory to each other is a religious idea. If you claim that free will is illusory or unreal, because everything is predetermined = cause-and-effect, you are submitting to a religious dogma. It is religious ideology or philosophizing which has imposed this contradiction of free will and determinism. Nothing in reasoning or science requires this contradiction of free will and determinism.
The Illusion that Free Will conflicts with Determinism
excerpt from a lecture by Jodi Magness
Jesus and his Jewish Influences
. . . We learn about this 40-year-long war from The War Scroll, which describes what's going to happen during this 40-year-long war, in great detail.
One of the peculiarities of this sect is that they believed in predeterminism. Everything is pre-ordained by God. And so this 40-year-long war, and what's going to happen during it, are pre-ordained by God and described in the War Scroll. But not only all future events were pre-ordained by God, but in fact everything was pre-ordained by God, meaning that this sect believed that there is no human free will at all. You've no freedom to choose what you do and what you do not do. Your own personal makeup, how many parts of you are good, how many parts of you are evil -- all of this is pre-ordained by God before you're even born.
One way to refute this explanation of "Free Will" vs. "Determinism" is this simple 2-step critique:
1. This explanation of "Free Will" and "Determinism" is totally arbitrary, not required by definition or logic, i.e., you're just arbitrarily choosing to make them contradictory because you want to, with no rule requiring you to make them contradictory; and
2. This explanation, if accepted, contradicts all of science and everyday practice, such as in law and in responsibility and accountability and decision-making, which all assume free choices.
You're unnecessarily making 2 choices here, for no reason: 1) you're accepting the above definition of "free will" and "determinism" in order to claim they contradict each other, and yet there is no need to submit to this definition; and 2) you have to reject all decision-making and accountability and legal responsibility as being meaningless. To make free will and determinism logically contradictory, you must make these two choices, both unnecessary, and one which abolishes all knowledge and science and decision-making and negates any judging people's behavior or choices or decisions.
There is no reason to choose either of the above, and nothing is accomplished by choosing them. Why should we reject all decision-making and all judgments of accountability, and why should we reject all legal decisions and responsibility for behavior, just because someone has this definition of "free will" and "determinism" to foist upon us? We are not required to submit to this definition of "free will" and "determinism." We can easily accommodate both "free will" and "determinism" without forcing them to contradict each other.
Instead of the above, "
Determinism" can be fully explained as follows:
It is possible (theoretically) to predict everything in advance, if one has "infinite" knowledge, or simply knowledge of everything that will happen, e.g., in human history or in earth history, etc. Hypothetically a "god" or "God" could have all this pre-knowledge of what will happen, down to the most minute detail.
But this doesn't negate the "free will" which also happens. It's totally arbitrary to say this pre-knowledge cancels out the free will, which itself is just part of the events happening. The free will, the choosing -- it's all just part of the total events happening along with everything else. So God (or anyone with enough pre-knowledge) knows the free will ahead of time, and can predict what the free choices will be. All those choices are still free, if there is no coercion. Just because someone can see it coming in advance does not make it an unfree choice.
One could predict slavery or other unfree acts taking place. But other acts are
free acts, which are also predicted. Just the predicting it doesn't change it from being free into something not free. The predictor can also predict the coercion taking place, when the slave trafficker or slave owner imposes "choices" onto the slave which are not free choices.
So here are two different explanations of "free will" and "determinism" --- and of these 2, one is compatible with our common sense decision-making and behavior every day, when we live our lives and make mostly free choices. By this understanding, there is both free choice and UNfree choice, both coercion at times and free choice at other times. And we hold each other accountable for our free choices, but not for our unfree choices when we were forced against our will. And in some cases there is ambiguity whether we acted freely or were coerced into doing something. So we might be "blamed" in part for what happened, but not totally. That fits our normal everyday experience, and so allows our decision-making and our scientific research and seeking answers and trying to make the world better.
Whereas the explanation making "free will" contradictory to "determinism" rules out scientific research and truth-seeking and trying to improve the world and planning and hoping for better outcomes.
The correct explanation has to be the one which best fits our normal experience and allows that we can learn and make the world better, rather than the explanation which rules out all science and improving and decision-making and judging some results as better than others.
That we can predict events in advance, or even God predicting EVERYthing in advance (if ALL truth can be known somehow) is totally compatible with the possibility that free will makes the choices even though those free choices are known in advance, from pre-knowledge of the events. So that there's no contradiction between the pre-knowledge/predeterminism and the free will. Rather, that free will is just one more phenomenon recognized in advance as one of the causes, as any or all the causes are predetermined and possibly knowable. It's all predetermined and so could be known ahead of time, if one has enough information. So it's both predetermined AND free at the same time -- no contradiction.
You could argue that the definition is whatever we want, and if we want to we can define "free will" and "determinism" as contradictory. And maybe we can define anything anyway we wish. But why should we choose to make these contradictory for no reason, and thus destroy all science and reasoning and decision-making? What is gained by making these two incompatible? There's nothing intrinsic to "free will" and "determinism" which forces them to contradict each other.
Rather, all we have to do is define "free will" as whatever drives us to our decisions or free choices, and "coercion" as whatever suppresses our free choices by threatening to deny us what we want, and "determinism" as whatever caused these, including the free choices we're driven to make and which might be known in advance in some cases. Those choices are still free, despite being predictable and even knowable in advance. Or, the ones coerced can be known in advance as something not free. The coercion is also knowable and predictable in advance, and this predictable coercion then makes the act unfree rather than free. It's not the predictability, but the coercion which made the act unfree, and when we could see that there'd be no coercion, then we'd also see that the act taken is a free choice, being non-coerced.
Predetermined and predictable, but free nonetheless, because not coerced.
