Good and short explanation, congratulations. I think that there is a huge paradox in this issue.
- If our will is determined by reasons in an absolutely necessary way, we are not free.
- If our will is not determined by reasons, our will is random, therefore we are not free.
It seems that we are doomed, or we should re-think how could we conceive our freedom in a way that allows us to avoid this uncomfortable paradoxes.
Absolutely! It's look like a paradox.
