If “scientism” is the bad tendency of scientists to pronounce on matters outside their bailiwick, them I hereby proffer a new term: “philosophism“. And I define it as “the practice of philosophers pronouncing on matters outside their expertise”. In the article below from the Irish Times, two philosophers Helen Beebee (University of Manchester) and Michael Rush (University of Birmingham) decide that questions of brain differences between sexes and genders, as well as the existence of free will, are questions that should not be left to scientists. (It’s common for philosophers to claim hegemony over free will at the expense of neuroscience). Their views constitute a good specimen of philosophism.
To be fair, they don’t completely agree with each other, and give science some room with questions of brain differences, but they still seem confused and muddled on both issues. I’ll explain below, but first read the short piece by Joe Humphreys, who interviews them both (I’ll use their initials when quoting the philosophers).

Joe Humphreys immediately irritated me at the start of the article with this characterization:
Science and philosophy have had a strained relationship in recent times. Their roles resemble that of a wide-eyed child and her grumpy uncle. Each time the youngster runs in with a new discovery, the older relative harrumphs: “Is that all? Sure, that doesn’t amount to anything?”
Philosophical pooh-poohing of neuroscience is particularly pronounced, especially giddy claims that brain scans have unlocked the secrets of human consciousness. Atheistic thinkers like Sam Harris and Jerry Coyne have latched onto current research to declare that free will does not exist. Rather, they say, our every decision is encoded in nature – a stance known as determinism.
First of all, I don’t know anyone who claims that “brain scans have unlocked the secrets of human consciousness.” Further, why are Sam and I described as “atheistic thinkers”? Our atheism has nothing to do with our views on free will or gender differences between brains, views that come from a scientific standpoint, not from our rejection of gods.
But never mind. The first philosophical misstep comes from Rush, who says this (questions in bold come from Humpreys):
Every couple of weeks there is a new study out on whether men’s and women’s brains differ. The majority view among neuroscientists now seems to be that brains are, in fact, gendered but it’s due to nurture rather than nature. What role do philosophers have in this debate?
MR: “If the differences come from nurture – which seems plausible if we’re talking about gender, because gender is a social phenomenon rather than a biological one – then the differences are not in any interesting way differences between kinds of brain; they’re differences in what we do to brains, or what kind of things we can make brains into.
“If we’re talking about the sexed nature of brains – a biological rather than a social phenomenon – then it’s plausible that there are differences between male and female brains, since they are intimately linked to, for instance, hormones, and the presence and levels of certain hormones vary depending on which sex one is.
“One role that philosophers have in this debate, as they have in any debate, is keeping the discussion honest.
“Neuroscientists can tell us what differences there are, if any, between male and female brains; philosophers can explain why the mere existence of the differences wouldn’t entitle us, despite what many people seem to think, to say that they were innate or outside our control.”
Let me be brief. Contra Rush, gender may be a biological phenomenon in an important way: someone who is born, say, in a male body who feels that they are female, and takes steps to look or identify as female, may well have done so because of biology. Transgender people often say that they feel they are of a different gender from their birth sex from a very young age. While this feeling could be socially conditioned, it may well be—and must often be—the result of cryptic biological phenomena, including wiring in the brain.
At least Rush admits that there could be biological differences between male and female brains: I hope so, because there’s plenty of evidence for that. But what is this with philosophers “keeping the discussion honest”? Do we scientists tend to dishonesty? Further, what is this about scientists being unable to tell us which differences are “innate” (presumably biological differences that may be evolved) or “outside our control.” Both of these are empirical determinations that are the bailiwick of scientists and empiricists, not philosophers. Philosophers can add clarity to discussions, and help weed out bad arguments, but they cannot tell us what is empirically true. Whether a phenomenon is “innate” or “produced by social forces” are empirical questions.
And who is going to keep the philosophers honest? (Curmudgeons like me, I guess.)
The confusion between social conditioning and inborn biological features continues, but let’s pass on to what really interests me: free will. Note when you read the discussion that neither Beebee nor Rush ever explicitly define what they mean by free will when they pronounce on it. At least “atheist thinkers” like Sam and I define it (we think of it as libertarian “you could have done otherwise” free will). In the bit below, Rush claims that free will is not a scientific matter because you cannot “run an experiment” on it. Jebus! What a canard! (That’s an insult to ducks.)
Another battle ground between neuroscience and philosophy surrounds the question of free will. Is there an experiment that could be designed to settle the matter once and for all?
MR: “No. Whether there is free will is not the sort of thing we can tell by looking. It’s easy to get carried away with the widespread successes of the scientific method and start assuming that it is the only – rather than just a really fruitful – way of getting to know things about the world.
“Some things, like what happens when you chuck caesium in the bath, are most easily discovered by, well, in that particular case, grabbing some caesium and chucking it in the bath. And standing well back.
“Some things we can’t discover by running an experiment. But if we can’t send out a search party to see if we have free will, and we don’t think the question is hopeless, how else might we set about it?
“What we do first is we define in careful terms just what we mean by asking if an action is free. Once we’ve decided what we’re asking about, we consider our other theoretical commitments, and we see if free will is consistent with those. Both those essential tasks are very difficult, but neither is achievable by running an experiment.”
Ummm. . . what about the series of experiments showing that you can predict people’s decisions with a significant level of accuracy by scanning their brains? Those are experiments, aren’t they? What about experiments in which brains are stimulated to produce “involuntary” actions, giving people a sense of agency where it doesn’t exist? What about diseases that efface people’s sense of agency? These are all empirical matters, and many are experiments; all bear on at least my conception of free will.
Rush, I fear, is either ignorant of these data or is using the usual anti-science trope in which something is claimed to be true but outside of science because “you can’t run an experiment on it.” Well, it happens to be the case that a lot of science depends not on experiments but on observations, analysis, and predictions. There are almost no experiments described in Darwin’s On the Origin of Species. Does that mean it’s not science? What about figuring out how stars evolve over time? That’s observation, not experiment. And so on. This is not rocket science, Drs. Beebee and Rush!
I will claim that because the laws of physics affecting matter are observed to hold universally, this shows that we have no free will in the contracausal sense. Our brains are matter, what we do depends on our brains and what impinges on them, and therefore our actions must be determined by the laws of physics alone. (This includes those laws that mandate some pure indeterminism, like the behavior of electrons. But that indeterminism still comports with the physical determinism of free will because we cannot use our will to affect electrons.)
Here Dr. Beebee also gets muddled about free will:
Thinkers on free will have divided into three camps: determinists (who say all future states of mind have prior causes in line with best scientific thinking), free-willists (who reject determinism), and compatibilists (who see no contradiction between free will and determinism). Which one are you?
HB: “Well, I’m not sure about determinism; I think that’s one for the physicists to figure out. But I’m a compatibilist so I think even if determinism turned out to be true, we would have free will.
“We wouldn’t be controlled by the laws of nature, or by our brains – as though we’d just be puppets being controlled by some unseen puppet-master. To put it crudely, there isn’t enough of a gap between me and my brain for it to really make sense to think that my brain is somehow controlling me. And as for the idea that laws of nature control me, well, I’m not even sure that makes sense.”
The physicists have already figured out that determinism refutes the notion of contracausal free will defined as ‘free will’ by people like Sam and me. Read some Sean Carroll (a compatibilist), Dr. Beebee! But note that she doesn’t define free will.
But she’s a compatibilist, so she has to adhere to at least one concept of free will that’s compatible with determinism. Sadly, she doesn’t say which one. And her second paragraph, in which she denies being a puppet is confusing. Beebee’s statement that “there isn’t enough of a gap between me and my brain for it to really make sense to think that my brain is somehow controlling me” is a simple Deepity. What kind of gap is she talking about? Finally, it makes perfect sense to say that the “laws of nature control me”: that’s what physical determinism of behavior is all about. I get the sense here that Beebee may be out of her depth, or else is using philosospeak to somehow attack determinism.
Some final waffling by Dr. Rush:
What about you Michael? Is determinism a rational stance?
MR: I think the answer is ‘yes’, but there are a couple of questions worth keeping separate. Is it rational to believe that every event was fully caused by some preceding event, according to the operation of some fixed natural laws? Sure.
“Whether that’s true, and what those laws are, look like jobs for physics to concern itself with. The second question is more worrying to some people: Is it rational to believe that if determinism were true we would have no free will? I think the answer to that is ‘yes’ as well.
“It’s also rational to believe we would have free will under those conditions. Whether or not we have free will won’t be decided by whether either view is irrational, just like two scientists can both be rational but disagree about whether the evidence they share points to the existence of a new boson.
Well, at least he argues that determinism (which is true) is a rational stand. As far as the “worrying” second question, “Is it rational to believe that if determinism were true we would have no free will?”, Rush waffles. All he needs to say is “yes, we have no free will in the contracausal sense if determinism is true, but if you define free will in a compatibilist way, then yes, we might have a form of free will.” The first question, whether contracausal free will exists, has already been answered in the negative, by evidence. The question of whether we have compatibilist free will is a semantic and philosophical one, and depends on your definition. Of course compatibilists always define free will in a way that we do have it: that, after all, is why they are compatibilists.
This is not rocket science, but somehow both Beebee and Rush manage to mangle language and thought, and wind up confusing the reader.
I defy the scientifically-minded layperson to read this piece and, at least with respect to free will, come up with a summary of what these two philosophers really think. All I can discern is that they want to elbow themselves into issues of free will that are susceptible to scientific investigation, and, keeping the scientists “honest”, want to tell us, “Hey, listen to us philosophers!” This is a prime example of philosphism.
