I was convinced by Sam's arguments about determinism, but my friend's behavior is making me reconsider.
Sam makes a compelling case against free will.
We don't choose our genes. We don't choose our parents. We don't choose the society we're born into. Even our thoughts seem to arise in consciousness before we're aware of them. From that perspective, free will appears to be an illusion.
But I have a friend whose experience has made me question this conclusion.
He grew up in an obese family. His parents are obese. His siblings are obese. By his mid-20s, he was obese as well.
Then he decided to change.
He completely changed his diet, started exercising regularly, and eventually lost roughly 100 pounds.
I've talked to him extensively about the process. He still craves donuts almost every day, but he chooses to eat oatmeal instead. He still doesn't enjoy exercising, but he does it anyway.
The transformation hasn't been entirely positive, either. He's left with a significant amount of loose skin, which he's very self-conscious about. His decision to get healthy has also created tension within his family. They often explain their weight by pointing to genetics, slow metabolisms, or the idea that they're simply "naturally big." So his transformation has completely undermined those arguments and has created friction and frustration between him and his family.
He's overcoming social pressure, family norms, genetic predispositions, cravings, and his own desire to avoid exercise.
From the outside, it looks as though he's making dozens of deliberate choices every day that directly oppose his conditioning.
I understand that a determinist would probably ask, "What caused him to become the family member who changed?"
But that's exactly what I'm struggling with.
If a family shares the same environment, similar genetics, similar access to information, and similar habits, yet one persistently overrides those influences while the others don't, what exactly is the deterministic explanation?
What am I missing?
