Free Will
The brain begins a decision before you feel you chose. So who actually chose?
Your hand goes to the glass before you've thought about it, and if someone asked, you'd say "I decided to take a drink." But in a handful of well-known experiments, the fingerprints of the decision showed up in the brain before the person felt themselves choosing. As though the choice had already been turning over inside, and the "I chose" arrived a beat late — just in time to put its name to something already done.
Level 2 The explanation▾
The experiments — Libet's, and the ones that followed — are solid. What people make of them is where it splits. Some read them as proof that choice is a story we tell ourselves; others say they catch the opening of a process, not the moment of deciding, and that a "veto" is still ours to use. What's measurable: there's brain activity that runs ahead. What's open: what that says about "choosing."
Philosophy hands us a useful distinction here. Even if every state is locked in by the one before it, "freedom" might not mean the absence of causes — it might mean acting from your own values and reasons. That's the compatibilist reading, and it's argued over too.
Level 3 Deeper▾
The tradition put choice right at the center and refused to make it easy: "All is foreseen, yet freedom is given" (Avot 3). An old way of holding the very same tension — being known in advance, against being free — with both ends in hand and neither one let go.
The limit. The experiments don't settle free will in either direction. What they do is deflate the cartoon version, the little self sitting at a console pushing buttons — without handing us a finished picture to put in its place.
What is known
Brain activity preceding the conscious report of a decision is measurable (Libet and others).
What is open
Whether this denies choice, shrinks it, or only maps the start of the process.
Off limits
That the experiments "proved" there is no free will — the interpretation is contested.
