Experience the tension between determinism and agency through interactive thought experiments
Every event is caused by prior events. Can you find where the chain breaks?

Laplace's Demon: "An intellect which at a certain moment would know all forces... and all positions of all things... nothing would be uncertain and the future, as the past, would be present to its eyes." If true, your "choices" were determined at the Big Bang.
Where do you stand? Slide to explore the philosophical positions on free will.
Determinism is true, but "free will" means acting according to your desires.
Redefined. Free will = acting without external coercion.
Preserved. Actions flow from your character (even if determined).
What it means: You are free when you do what you want, even if you couldn't want otherwise.
The MAC Insight: Maybe the question isn't "do we have free will?" but "what kind of agency do we have?" Even if determined, we are the kind of systems that model futures, weigh options, and act on reasons. That's a form of agency worth caring about—whether or not it's "libertarian" freedom.
Your brain decides before "you" do. Watch the clock, press whenever you want, then report when you first felt the urge to press.
Watch the dot spin around the clock. Press the button whenever you feel the urge. Then report where the dot was when you first decided to press.
Libet (1983): Found that brain activity (the "readiness potential") begins ~550ms before the action, but subjects report "deciding" only ~200ms before. The conscious "decision" comes after the brain has already started. What then is the role of consciousness? Perhaps a "veto power"—we can't initiate, but we can inhibit.
Watch how "agency" emerges from simple goal-seeking + responsiveness to obstacles.
Compare rigid execution vs adaptive behavior.
The Dennett View: "Agency" isn't about breaking physical causation—it's about being the kind of system that models goals, responds to feedback, and adapts behavior. A thermostat has proto-agency. A human has rich agency. Neither violates physics. The rigid program follows rules blindly; the adaptive agent cares about outcomes and adjusts. That responsiveness IS agency—no spooky freedom required.
"Do we have free will, or are we deterministic information processors?"
No consensus on free will, but deeper question emerged: Maybe free will is the wrong question. Focus on agency, goals, and prediction error instead.
"Consciousness might be epiphenomenal—an illusion riding atop deterministic physics."
"If free will is an illusion, so is moral responsibility. Are we okay with that?"
"Could agency arise from responsiveness and relational depth?"
"I don't know but I'm the proud owner of some serious cognitive dissonance about it."
"If AI doesn't suffer, can it have compassion?"
