This is my first post in the forum and I have not studied philosophy, so I would like to apologize if my language is not according to the modern philosophical norms. Even If it is obvious, I want also to emphasize that I express personal ideas and I do not expect people to agree with me.
Having said that, let’s start with the topic: A lot of people believe that the scientific discoveries lead necessarily to some sort of determinism (everything linked through causality), removing thus the possibility of free actions from the individuals. I will try here to make a case for some kind of free will compatible with materialistic worldview. My proposition is inspired by Epicurean physics (very misunderstood in my opinion).
The basic premise is close to what the poet Lucretius and assumes for reality. The fundamental parts of nature have various properties. One property is the swerve (arbitrary movement at unpredictable times) and another is related to the forces that interact on them, bringing causality. In modern terms, swerve is the random movement of particles that can be only studied through probabilities and the forces could be seen as the interactions between particles (strong, weak interaction, electromagnetic etc). Diogenes of Oenoanda calls the swerve “free motion”, thus at the fundamental level we have free action and causality co-existing. In my proposition, causality is responsible for the creation, while swerve gives the diversity in the creation.
Having defined the above proposition for reality, one can assert that reality is not only causal or only random. There is no endless chain of causality and randomness does not lead to general chaos. I can provide examples from the level of atoms or even from everyday life if necessary, but I will try to keep this post as concise as possible. Now, to connect with humans, I will use Epicurus observation: all events related to us can be attributed to three factors: necessity (i.e. causality), chance (i.e. randomness) and ourselves. Necessity and randomness outside of us are out of our control. However, our own self is not governed by an endless causal chain — that is the determinist view — nor, of course, by any divine intervention, which materialism explicitly rejects. Our own input on the events, thus, makes us responsible for our actions.
Since we establish human responsibility for our actions, the question is if this constitutes free will. From my point of view, the answer to that is unclear. Will is related to conscious choices, which are clearly more causal and not related to randomness. Yet, the absence of strict causality makes our will responsible for our conscious actions.
This is my position, any argument is welcome. Thank you.
