begriff.sty - a LaTeX2e package for typesetting begriffsschrift This style style can be used with LaTeX to typeset material written in Frege's Begriffsschrift. It defines eight new LaTeX math mode commands: \BGassert - generates an assertion sign \BGcontent - generates an assertion sign \BGnot - generates a negation sign \BGquant{v} - generates a universal quantifier with variable v \BGconditional{a}{c} - generates a conditional with antecendent a and consequent c. Note that in the Begriffsschrift, the antecendent is placed below the consequent. (the following three commands were introduced in version 1.5) \BGterm{x} - creates a right-justified terminal node x \BGstem{x} - inserts arbitrary LaTeX maths x into a non-terminal node \BGbracket{x} - places the expression x inside brackets You also have the normal resources of LaTeX math mode, and (if you have the amssymb package, AMS symbols) at your disposal; so, you can use \mathfrak{v} to get a fraktur character, \acute{v} to get a character with a slanting hat, and \alpha (etc.) to get greek letters. You can also tweak the appearance of the resulting material by modifying the values of the following lengths: \BGthickness - the thickness of lines (by default 0.4pt, bigger numbers = bolder) \BGbeforelen - the length of line inserted before a begriffsschrift symbol \BGafterlen - the length of line inserted after a begriffsschrift symbol \BGspace - the length of space inserted between begriffsschrift and normal maths (and, since version 1.5) \BGlinewidth - the total width of the diagram This is version 1.6 (20th May 2005) which includes: Changes made in October 2004 by Richard Heck <heck@fas.harvard.edu> Purpose of changes: To make the format of the formulae closer to how they are set in Frege's published works. And some additional changes made by Josh Parsons (May 2005) to fix a problem with linespacing. The style file is hereby placed under the GNU General Public License.
