Free Will and Intensional Operators, Part I



In the Canadian Journal of Philosophy, Fabio Lampert and John William Waldrop recently offered a rather confusing argument about free will. 

They didn't argue for it or against it precisely, but sought to outline what a solid argument for it or against it might look like.  They seem sure that no sound argument to either conclusion has appeared yet, despite the voluminous attempts.

"Free will and intensional operators" is the title of their article, in the February 2026 issue. As one might expect, the phrase "intensional operators" plays a big part in their discussion. So does the word "closure". 

They don't really define what they mean by [epistemic] closure in this context, but I expect that it means here that for any domain of discussion X, the domain is closed if and only if we can safely add to our knowledge by taking the enatilment of what we know as also ... known. [This is different from causal closure.] 

Free will, for Lampert and Waldrop, is not so much defined as typified.  I have free will if I can be said to have a choice about something -- such as, to raise my arm at some near-future time (t). I suppose (not an example of theirs) if I am in attendance at a friend's wedding and the officiant says "anyone who objects to this union, raise your hand," then it matters whether we say I have a choice to raise my hand at that t.

An argument against free will from closure might start off this way -- and this time I am using one of their examples, though revised a bit by my own stylistic imperatives:

1. Consider the proposition "It was true a million years ago that you would raise your hand at t"  - you have no choice about the truth of THAT proposition. So we might add the intensional operator "necessarily" to it.  

2. Necessarily, it WAS true a million years ago that you would raise your hand at t.

3. Which entails: you have no choice about raising your hand at t. 

 The first step, then, is that if p is a truth about the distant past then it is fixed.  It is not up to anyone. The second step is more complicated.  This sounds like a reference to determinism. Given all the laws of nature, and the condition of the world a million years ago, it was necessarily the case that someday there would come to be such a person as you, sitting in the Church in question, and that THAT person would raise his hand.  But if that is what is meant, this smply assumes the problem away. Yes, (3) follows from (1) and (2) but the point doesn't even seem worth making since the assumption is heroic.

But that would be causal, not epistemic, closure. Lampert and Waldrop are after something more general.  Because of epistemic closure, if it was true a million years ago as a purely formal logical matter that you would raise your hand at t, then it is necessarily true if you indeed are going to raise your hand at t, [and the domain we are positing to be closed may include chance facts.]

 Here we get to the twist.  Lampert and Waldrop tell us that the long-neglected point is that the key issue in the debate over free will in the face of such arguments is whether what they call the "N operator" --the inference to the necessity of the raised hand, is intensional or hyperintensional.

Huh?  Hang in there.  I'll come back to this tomorrow.

  1. The statement "I have free will if I can be said to have a choice about something -- such as, to raise my arm at some near-future time (t)" has a small problem and a big problem. The small one is that "at some near-future time" is unnecessary. I might decide as a teenager that, on my eightieth birthday, I will raise my arm. The big problem is that the statement begs the question. To say that you can have a choice about something proves that you have free will assumes what it is trying to prove: that you can have a choice about something.

    1. About the small problem: at some point along the time line an act of will becomes merely a plan. A teenager is not WILLING to raise his hand when he is 80. He may be planning to do so. The notion of [freely] willing by bodily movement is inherently near-term. About the large problem: I agree. These authors should have attempted an actual definition rather than just you-know-it-when-you-see-it examples. Anyway, this post just tries to get you onto the roller coaster. Tomorrow, we take a bit of a ride.

    2. If I decide to raise my hand ten seconds from now, it’s only a plan, because I could change my mind. To will must be simultaneous with the act.

A Story About Coleridge

This is a quote from a memoir by Dorothy Wordsworth, reflecting on a trip she took with two famous poets, her brother, William Wordsworth, and their similarly gifted companion, Samuel Taylor Coleridge.   We sat upon a bench, placed for the sake of one of these views, whence we looked down upon the waterfall, and over the open country ... A lady and gentleman, more expeditious tourists than ourselves, came to the spot; they left us at the seat, and we found them again at another station above the Falls. Coleridge, who is always good-natured enough to enter into conversation with anybody whom he meets in his way, began to talk with the gentleman, who observed that it was a majestic waterfall. Coleridge was delighted with the accuracy of the epithet, particularly as he had been settling in his own mind the precise meaning of the words grand, majestic, sublime, etc., and had discussed the subject with William at some length the day before. “Yes, sir,” says Coleridge, “it is a maj...

Searle: The Chinese Room

John Searle has become the object of accusations of improper conduct. These accusations even have some people in the world of academic philosophy saying that instructors in that world should try to avoid teaching Searle's views. That is an odd contention, and has given rise to heated exchanges in certain corners of the blogosphere.  At Leiter Reports, I encountered a comment from someone describing himself as "grad student drop out." GSDO said: " This is a side question (and not at all an attempt to answer the question BL posed): How important is John Searle's work? Are people still working on speech act theory or is that just another dead end in the history of 20th century philosophy? My impression is that his reputation is somewhat inflated from all of his speaking engagements and NYRoB reviews. The Chinese room argument is a classic, but is there much more to his work than that?" I took it upon myself to answer that on LR. But here I'll tak...

Five Lessons from the Allegory of the Cave

  Please correct me if there are others. But it seems to be there are five lessons the reader is meant to draw from the story about the cave.   First, Plato  is working to devalue what we would call empiricism. He is saying that keeping track of the shadows on the cave wall, trying to make sense of what you see there, will NOT get you to wisdom. Second, Plato is contending that reality comes in levels. The shadows on the wall are illusions. The solid objects being passed around behind my back are more real than their shadows are. BUT … the world outside the the cave is more real than that — and the sun by which that world is illuminated is the top of the hierarchy. So there isn’t a binary choice of real/unreal. There are levels. Third, he equates realness with knowability.  I  only have opinions about the shadows. Could I turn around, I could have at least the glimmerings of knowledge. Could I get outside the cave, I would really Know. Fourth, the parable a...
