How do we know that the external world exists in anything like the form we think it has? Assuming that we think, therefore we are, and that it’s hard to doubt the existence of our own immediate sensations and sense perceptions, can we prove that our senses give us reasonably reliable access to what the world is really like?
One thing that stands in our way is a variety of “skeptical scenarios” or “undefeated defeaters” (Knowledge is basically justified true belief without any undefeated defeaters.) Here are some well-known skeptical scenarios/defeaters: How do you know that you are not… (i) dreaming, (ii) being fooled by an evil demon; (iii) currently using a really good VR-rig; (iv) on a “holodeck” like the one in “Star Trek”, (v) currently in William Gibson’s immersive, plugged-in version of “cyberspace”, (vi) in “The Matrix” or, anyway, a matrix; (vii) in Nozick’s “experience machine”; (viii) a brain in a vat being electro-chemically stimulated to believe you are not just a brain and the world around you is going on as before; or (ix) part of a computer simulation? (You don’t need to recognize all of these to get the general idea, of course.)
David (“The Hard Problem (of Consciousness)”) Chalmers, in his new book “Reality+”, doesn’t want us to think of these as skeptical scenarios at all. Being a brain in a vat, he says, can be just as good as being a brain in a head. Most of what you believe that you know about, say, where you work, what time the bus comes, or how much is in your checking account is still true, relative to your envattedness, according to Chalmers.
It seems tenuous to me to claim that “most” of your beliefs could be true in such a scenario. Read more »

Why do I have to help?
Among the ideas in the history of philosophy most worthy of an eye-roll is Aristotle’s claim that the study of metaphysics is the highest form of eudaimonia (variously translated as “happiness” or “flourishing”) of which human beings are capable. The metaphysician is allegedly happier than even the philosopher who makes a well-lived life the sole focus of inquiry. “Arrogant,” self-serving,” and “implausible” come immediately to mind as a first response to the argument. It’s not at all obvious that philosophers, let alone metaphysicians, are happier than anyone else nor is it obvious why the investigation of metaphysical matters is more joyful or conducive to flourishing than the investigation of other subjects.
In late January the United States Senate Health, Education, Labor and Pensions (HELP) Committee released a draft discussion of its COVID-prompted public health bill titled, “Prepare for and Respond to Existing Viruses, Emerging New Threats, and Pandemics Act” (
Soon K.N.Raj gave up his Vice-Chancellorship and moved to his home state, Kerala, and started a new institution, Center for Development Studies (CDS). He tried to lure me (and Kalpana) to join the faculty there, and even offered to get us land on which he’d persuade his friend Laurie Baker (a resident British-Quaker architect) to build us a low-cost, energy-efficient beautiful house (like his own). At CDS, he not merely provided intellectual leadership, he was the pater-familias for the group. After a whole day of teaching and seminars, in the evening he’d visit his colleagues’ homes, try to solve their multifarious domestic problems, while his wife, Sarsamma, will minister to their sundry medical needs. Once driving me to the airport, when I was all praise for the young institution and the community he was in the process of building, he asked me if I had any word of criticism. I told him it was too much of a “Hindu undivided family” for my taste. Raj corrected me and said it was not “Hindu” — he did not seem to mind the “undivided family” part.

In the game of chess, there are dramatic moves such as when a knight puts the king in check while at the same time attacking the queen from the same square. Such a move is called a fork, and it’s always a delicious feeling to watch your opponent purse his lips and shake his head when you manage a good fork. The most dramatic move is obviously checkmate, when you capture the king, hide your delight, and put the pieces back in the box. But getting to either the fork or checkmate involves what’s known in chess as positioning, and for the masters, often involves quiet moves long in advance of the victory.
