Death and Vagueness

Consider the following theses.
(A) For any person P, P exists iff P is alive.
(B) For any person P, P is alive iff P is not dead.
(C) Whether or not some person is dead is vague.
(D) Whether or not someone exists is not vague.
On the face of it, these four theses seem to be incompatible. If [...]

Seeing in Four Dimensions

Attention metaphysicians and philosophers interested in the four-dimensionalist/three-dimensionalist debate. A few mathematicians have created some videos that are designed to help people try and visualize a four-dimensional object.
Pretty cool.

75th Philosophers’ Carnival

Welcome to the 75th Philosophers’ Carnival. Doesn’t 75 seems like a number worthy of celebration? I thought so, and so I’ve been working quickly for the last month to make sure that I would have a special treat for everyone. It’s in the bonus section at the end.

Now I Have A Puzzle About “Now”

In an earlier post (How Long Is The Present?) we had a little warm-up exercise. I assumed that presentism must hold that the only time that exists is a durationless present moment. I also tried to motivate it with two arguments. Let’s just take that assumption for granted in this post. Presentism must hold that [...]

How Long Is The Present?

I have some half-baked puzzles for presentism, but before I lay those out - I have a quick warm-up exercise.

How Long Is the Present?
I assume that if presentism is true, then the answer is durationless. This seems like a fair assumption. However, I vaguely remember someone describing a version of presentism according to which the [...]

Sympoze IM

I just installed a simple Instant Messenger feature in Sympoze. You can IM your contacts and start chat rooms. It seems to work well, but I think you might need to allow pop-ups from Sympoze.
It seems like it could be a useful feature.

Sympoze: Analysis RSS Feed Integrated

I just set up Sympoze to automatically import each article published in Analysis as it’s own separate scoop.
As with the blogroll posts, you must look under the Upcoming Tab. The articles don’t make the front page until users vote them up.
I’m going to do this for all of the major journals. It will save [...]

Sympoze Update: Blogroll Integrated

I just worked it out so that Sympoze will automatically import each post from the blogs I track in my philosophy blogroll and submit it as a scoop. All readers can now sift through all of the posts in my blog roll via Sympoze. Users can vote the blog posts up and have them promoted [...]

Sympoze - Social Bookmarking and Content Promotion for Philosophers

I decided to start a social bookmarking/content ranking site like Digg or Reddit for philosophers.
Here’s the site. It’s called Sympoze.
It’s a kind of social network site that will help everyone find really great philosophy content online. The idea is simple: users submit links to philosophy content they like - blog posts, online papers, or journal [...]

Mysteries of Time and the Multiverse

Here’s a recent pop-science article from the LA Times. It’s an interview with physicist, Sean Carroll (Caltech). He discusses the possibility of multiverses and the hypothesis that our universe is an off-shoot of some other universe in the multiverse.
