For years I was convinced that the extrinsic constitution model of divine knowledge, which theists who accept divine simplicity must accept,...

I ran across this old post of mine and it made me think that there is an interesting distinction between two kinds of change which one migh...

It’s common to say that presentism entails the A-theory. But that’s not so clear. Suppose that time can pass in the absence of change. Now i...

Here’s a way to think about presentism. We have a three-dimensional reality and temporal modal operators, such as Prior’s P , F , H and G ...

There is a structural similarity between the main reasons for adopting the A-theory of time and the knowledge argument against physicalism. ...

Truth supervenes on being is the thesis that if two worlds have the same entities, they are otherwise the same. I just realized something th...

All reality is such that it can be known perfectly from the point of view of God. The point of view of God is eternal and timeless. Thus,...

This morning I find myself feeling the force of presentism. I am finding it hard to see my four-dimensional worm theory as adequately explai...

Philosophers sometimes use thought experiments concerning the asymmetry of attitudes towards future and past events as arguments for a metap...

Could there be times that are never present? At first sight, this seems a contradiction: surely, each time t is present at itself. Given th...

It's oft stated that Ockham's razor favors the B-theory over the A-theory, other things being equal. But the theoretical gain here i...

B-theorists are often accused of destroying the reality of change. That's a false accusation. B-theorists may have a reductive theory of...

Suppose that Jim lives a normal human life from the year 2000 to the year 2100. Without looking at a clock, what probability shoul...

A grad student was thinking that Platonism isn't dominant in philosophy, so I looked at the PhilPapers survey and indeed a plurality of...

Famously, D. C. Williams ridiculed the deep-seated intuition (at the heart of Bergson's thought, of course) that there is a f...

I used to think that A-theorists cannot consistently believe in time travel. I think I was mistaken. As best as I can reconstruct my line ...

One version of McTaggart's argument for the unreality of time is: If time is real, there is change. If there is change, there is...

A-theorists talk of something called "becoming" which they say B-theorists have no room for. I don't really understand wh...
