Truth and Meaning What have truth and meaning got to do with each other? A dominant view has it that the two are deeply connected—specifically, meanings are truth conditions.[1] The view comes in several varieties, but the central thought is that the meaning of a sentence consists of the state of affairs […]
The Selfless Machine In a striking passage from The Selfish Gene Richard Dawkins writes as follows: “Other replicators perhaps discovered how to protect themselves, either chemically, or by building a physical wall of protein around themselves. This may have been how the first living cells appeared. Replicators began not merely to exist, […]
Criteria of Meaningfulness The positivists created a question that had not existed before, viz. what is the criterion for whether a string of words is meaningful? Their proposal was that such a string is meaningful if and only if it is empirically verifiable (with due allowance made for analytic sentences). The intention was […]
Action and Acting Jack gets up, goes to the kitchen, opens the fridge, takes out a beer, pops the cap, and drinks it. Why did he do that? Because he wanted a beer and thought there was one in the fridge. The philosopher says that Jack’s action is explained by his having […]

The same is not true of other subjects: physics, chemistry, geology, biology, psychology, history, economics, English literature, etc. In these subjects a certain sector of […]
On Mind-Brain Relations Various relations between mental events and brain events have been (and could be) posited: correlation, causation, simultaneity, supervenience, spatial coincidence, composition, part-whole relations, and identity. It is fair to report that these relations are first found outside of the mind-brain relation and then applied to that relation; we […]
Scientific Knowledge No doubt scientific knowledge is impressive and enchanting: science has learned so much of interest about the world, with many practical applications. The human brain is lucky to be able to obtain and contain such knowledge. It looks like the best knowledge on planet Earth; if there were a competition […]
What is Nature? What falls under the concept of nature and what does not? What does the concept include and what does it exclude? The OED defines “nature” as follows: “the phenomena of the physical world collectively, including plants, animals, and the landscape, as opposed to humans or human creations”. The Cambridge […]
