Or, rather, the very real threat to Physicalism posed by Philosophical Zombies.
On the one hand, there are the Night of the Living Dead, Dawn of the Dead, Shaun of the Dead, Walking Dead, zombies, which are rotting, but animated, corpses that devour human flesh and can only be stopped by destroying their brains. They pose a physical threat.
On the other hand, there are philosophical zombies that pose a much deeper, more unsettling threat to physicalism itself. Philosophical zombies look and act just as we do, but they have no internal, phenomenal mental life. Like celebrity influencers.
Physicalism is, roughly, the view that everything real is either physical or reducible to something that is physical. Arguably, it’s the philosophical view that undergirds modern science. The physicalist slogan that I grew up with was “all concrete particulars are physical.”
That is, there are abstract objects (like numbers or sets) as well as generalizations about concrete objects (say, about horses having four legs). And these are in some attenuated sense real. But any given example of a nonabstract object will be physical. When it comes to the human mind, physicalism does not have to mean that “redness” or “pain” is some particular unitary brain state, but rather that every time you perceive something as red your perception is caused, and constituted, by you being in some particular brain state. That’s called token physicalism or nonreductive materialism.
There are plenty of objections to this view. In a recent 3 Quarks Daily article Katalin Balog discussed the problem of causality. Since most philosophers accept the “causal closure of the physical” – every physical event has a physical cause, so nothing nonphysical can cause something in the physical world – mental events like pain or redness are, at best, epiphenomenal*. Even if they exist, in other words, they are caused by physical events or processes, but they can’t cause anything. Yet, the causal objection goes, isn’t it the fact that I see a light exemplifying the phenomenal property of redness (as philosophers used to say) that causes me to stop?
I want to discuss a different argument, however. The one about zombies, which Balog also mentions in passing. Rather, than being causal this is an objection to physicalism from phenomenal consciousness. Read more »




In his inaugural speech on 20 January 2025, Donald Trump jumped into the fray on the contentious issues of gender identity and sex when he announced that his administration would recognise “only two genders – male and female”. At this point there is no conceptual clarity on his understanding of the contested issues of ‘gender’ and ‘male and female’, but we do not have to wait too long before he clarifies his position. His executive order, ‘Defending Women from Gender Ideology Extremists and Restoring Biological Truth to Federal Government’ signed by him soon after the official formalities of his inauguration were completed, sets out the official working definitions to be implemented under his administration.


If you had to design the perfect neighbor to the United States, it would be hard to do better than Canada. Canadians speak the same language, subscribe to the ideals of democracy and human rights, have been good trading partners, and almost always support us on the international stage. Watching our foolish president try to destroy that relationship has been embarrassing and maddening. In case you’ve entirely tuned out the news—and I wouldn’t blame you if you have—Trump has threatened to make Canada the 51st state and took to calling Prime Minister Trudeau, Governor Trudeau.






How are we to live, to work, when the house we live in is being dismantled? When, day by day, we learn that programs and initiatives, organizations and institutions that have defined and, in some cases, enriched our lives, or provided livelihoods to our communities, are being axed by the dozen? Can one, should one, sit at the desk and write while the beams of one’s home are crashing to the floor? Or more accurately: while the place is being plundered? There have been moments of late when I’ve feared that anything other than political power is frivolous, or worse, useless. In those moments, I myself feel frivolous and useless. And worse than that is the fear that art itself is useless. Not to mention the humanities, which right now in this country is everywhere holding its chin just above the water line to avoid death by drowning. It can take some time to remember that these things are worth our while, not because they’ll save us today, but because they’ll save us tomorrow.
