# How is the philosophy conclusion symbol drawn?

Looks like this:

(Maybe called "therefore"?)

Also, what's a good guide for philosophy symbols in LaTeX?

Edit: Looked up http://osl.ugr.es/CTAN/info/symbols/comprehensive/symbols-a4.pdf for "conclusion", "therefore" and "philosophy", and it's not what I'm looking for.

Edit 2: No, in page 35 what appears is not what I'm looking for. This symbol is drawn before the "conclusion" sentence in Philosophy, so it would be:

premise1
premise2
\conclusion conclusion


Edit 3: According to http://www.artofproblemsolving.com/Wiki/index.php/LaTeX:Symbols , \vdash is the symbol I need, But I'm not able to insert it into a sentence like this:

\vdash conclusion


It tells me:

Missing $inserted. Missing \endgroup inserted. Lonely \item--perhaps a missing list enviroment. \begin{document} ended by \end{enumerate} Extra \endgroup  If I remove \vdash from the line it's inserted to, all these errors disappear and the document compiles correctly. Maybe I'm missing a package? - Did »How to look up a symbol?« reveal something? – clemens Mar 10 '13 at 12:34 See p35 of this. – Jubobs Mar 10 '13 at 12:35 I'd say that \vdash is what you're looking for. – egreg Mar 10 '13 at 12:40 @Pyrobisqit \vdash can only be used in math mode, like so, for instance: $\vdash$. – Jubobs Mar 10 '13 at 12:52 ## 3 Answers It is good practice to wrap your wrap the \vdash into a command. That way you can change the command once in the preamble (say you suddenly need it bold, or larger, or whatever) and it will be changed everywhere in the document. E.g., \documentclass{article} \newcommand{\concl}{\ensuremath{\vdash}} \begin{document} \begin{itemize} \item [P1] first premise \item [P2] second premise \item [\concl] conclusion \end{itemize} \end{document}  - Sounds much cleaner indeed, applied to my LaTeX master template! – Pyrobisqit Mar 10 '13 at 15:50 Solved! What I did is this: \begin{itemize} \item [P1] Premise1 \item [P2] Premise2 \item [P3] Premise3 \item [$\vdash\$] Conclusion
\end{itemize}

For what it is worth, http://gregorywheeler.org/latex/phil-style2.html provides a few esoteric philosophy symbols, plus links to sites for logicians. There is also a now-defunct tex-blog (http://www.charlietanksley.net/philtex/) and Charles Tankley's guide to LaTeX for philosophers: http://www.charlietanksley.net/latex-guide.html
