Research and publications

Most of my work has focused on the philosophies of Gottlob Frege and Bertrand Russell, especially their philosophical logics and their import for contemporary discussions in philosophy of language, intensional logic and the philosophy of mathematics. I am also interested in informal logic, ethics, and the history of logic and analytic philosophy generally.

You can also download my CV.

Most of my publications are available below. If not, email me and I’ll send you a copy. Questions and comments welcome.

Online Editions

I think it is a good idea for academics to produce high-quality editions of important public-domain works, which are often available only in much lower quality than books not in the public domain. This is the only way to preserve the integrity of these texts in the centuries to come.

So far I have worked on three such projects, and hope to do more in the future.

Other E-Projects

Philosophical rock

Monads Logo

I maintain the website for The 21st Century Monads; the rockingest of all Philosophical Rock Bands.

gappi: get a PhilPapers item

I wrote gappi, which is a simple bash script for fetching BibTeX records from the PhilPapers database.

Visit the gappi page on Bitbucket for installation and usage information.

Online logic exercises

I am working on creating open source, online logic exercises for various free or open textbooks. Those I created for Gary Hardegree’s Symbolic Logic: A First Course can be found here.

I wrote the first draft of a proof checker for the Forall x book; although I am still working on this project, it has been modified by others as well. A demo page up and running here.

My music server

I run a music server to stream my music collection anywhere. Visit the login page; if you want guest access, email me for a password.

Other stuff

I’m working on a live-updating in-browser LaTeX editor built on CodeMirror with added JavaScript and a PHP back-end. I have a working version on my own computer, and hopefully I can distribute the code eventually after I clean it up a bit.

Previously, I wrote a vim plugin in and set of helper scripts to provide a live-updating PDF preview of LaTeX documents with MuPDF. I don’t use this anymore, but the code is still available: vim-live-latex-preview-0.9.tar.gz, and is available from ArchLinux’s AUR repository.

Other/Stuff I Like

Open source/free software

The internet was built on the back on free software, but is increasingly being taken over by commercial interests.

When you give yourself over to Apple, Microsoft, et al., you are making a vote for a more corporation-controlled internet. You are also using products that have been made defective deliberately so that corporations can make more money. Take back the web!

The free-license, open source alternatives may take awhile to learn, but they make up for it in power, efficiency, adaptability and freedom.


As Neal Stephenson has said: “Macs are hermetically-sealed sedans that look great and have a lot of advertising. Windows machines are big SUVs that break often, but they’re everywhere and everyone knows how to use them. Linux computers are free tanks that go 90 mph in swamps, get 100 mpg and never break down.”


Beautiful typography without the proprietary price tag.
