Ludwig Wittgenstein:
Tractatus Logico-Philosophicus
Side-by-Side-by-Side Edition

Created in part to serve a pedagogical need, I have undertaken a project to create a decently typeset version of Wittgenstein’s Tractatus-Logico-Philosophicus (1922) that presents Wittgenstein’s German original text alongside both major English translations: the Ogden (or Ogden/Ramsey) translation, and the Pears/McGuinness translation.

Right now five versions are available in three file formats. All contain Russell’s introduction, and a hyperlinked English index. (The index is taken from the Pears and McGuinness edition.) They were created by cleaning up and checking versions of the text found elsewhere on Public Domain sites online to create LATEX source which was then converted to other formats. I believe these are substantally more correct than most other versions available on the internet, some of which are rife with errors. Nevertheless, it is possible that errors remain. If you discover any, please email me at

In the future, more could be done to track changes between releases of the editions. Thanks to Josh Fry to bringing a number of discrepancies in earlier versions to my attention. (For information on changes between the 1922 and 1933 versions of the Ogden translation see C. Lewy, “A Note on the Text of the Tractatus”, Mind 76 (1967): 416–423.) Thanks also to Michael Sperberg-McQueen and Tim Kraft for helping spot typos and other issues in the German.

Please also see The University of Iowa Tractatus Map, which is based on this text, and represents the hierarchical nature of the propositions on the work in a visually suggestive way.



(Created with pdfLATEX (the source is also available below). The images are infinitely scaleable vector graphics (made with the PGF/TikZ package). This is the best version typographically, the best for printing, and the most likely to be displayed consistently across various devices. It is however less flexible, and less likely to convert well to other formats. Two sizes are available.)


HTML (Web page)

(Recommended for viewing online, or converting to another format. Two layouts of HTML (XHTML) are available.)

  • HTML Side-by-side-by-side in three columns (Displays all three versions at once, but with different color backgrounds—good for doing quick comparisons; 731 KB + embedded fonts and images)
  • HTML hyperlinked version (Displays one version at a time, but with links to the corresponding part of the other versions; useful on smaller screens, or for printing only one version; ~800KB split up over multiple files)

E-book format

(For mobile devices.)

  • ePub version (works on most e-book devices and software, 1.3 MB)
