Illusions of Mind
Illusions of Mind Is it possible to maintain that we know other minds better than we know other bodies—or even our own body? Can we be more skeptical about our knowledge of bodies than our knowledge of other minds? That sounds unlikely, given that we infer other minds from other bodies: we see other bodies […]
Romances
Romances A romance is a love affair between two people. But this doesn’t specify what kind of love affair: it could be sexual love, but it need not be. It could be an intellectual romance; then it connotes shared passions and interests of an intellectual nature. The idea is of a cooperative, committed, passionate relationship […]
Mathematical Philosophy
Mathematical Philosophy In 1919 Bertrand Russell published a book titled Introduction to Mathematical Philosophy, written while he was in jail; but the title is somewhat misleading, because the book isn’t about doing philosophy mathematically but about the philosophy of mathematics. Still, Russell did do a fair amount of mathematical philosophy: the theory of descriptions, existence […]
God and Matter
God and Matter Berkeley was convinced that matter and God are incompatible. If matter exists, God doesn’t; and if God exists, matter doesn’t.[1] I want to spell this out a bit, because Berkeley is onto something important here. His basic point is that if you postulate matter, you open the way for skepticism, mystery, and […]
The Selfless Gene
The Selfless Gene The logic of selfish gene theory is impeccable, but its usual formulation leaves something to be desired in point of strict and literal accuracy. I propose to remedy that. No harm will be done to the theory thereby; we will merely clarify its exact import. First, some terminology: by “gene” I will […]
Mathematical Knowledge
Mathematical Knowledge We can all agree that human beings have mathematical knowledge. We understand mathematical concepts. But how extensive is mathematical knowledge—what subjects are mathematical? The OED defines mathematics as “the branch of science concerned with number, quantity, and space, either as abstract concepts or as applied to physics, engineering, and other subjects”. But the […]
Mathematical Logic
Mathematical Logic It has always been felt that logic and mathematics have a lot in common. This led to the idea that mathematics reduces to logic. I am going to argue that the converse is true: logic is basically mathematical; logic “reduces” (expands) to mathematics. It’s more complex than it looks in the textbooks. The […]
