\ProvidesPackage{principia}[2023/03/13 principia package version 2.0] %This is the principia package is for representing notations in Whitehead and Russell's ``Principia Mathematica" close to their appearance in the original.
%Version 1.0 (superseded by Version 1.1): Covers typesetting of notation through Volume I. 2020/10/24
%Version 1.1 (superseded by Version 1.2) minor updates: fixed the spacing of scope dots around parentheses; fixed spacing of theorem sign; fixed spacing around primitive proposition and definition signs. 2020/10/25
%Licensed under LaTeX Project Public License 1.3c. 
%Version 1.2 (superseded by Version 2.0) (minor updates): boldfaced (`thickened') the truth-functional connectives, existential quantifier, set and relation symbols; added numerous commands for typesetting brackets and substitutions into theorems. 2021/02/25
%Version 2.0 (major update): extends the package to cover typesetting of all notations in Volume II; removes package dependency on marvosym. 2023/03/13

%Principia package requirements
\usepackage{amssymb} %This loads the relation domain and converse domain limitation symbols.
\usepackage{amsmath} %This loads the circumflex, substitution into theorems, \text{}, \mathbf{}, \boldsymbol{}, \overleftarrow{}, \overrightarrow{}, etc.
\usepackage{pifont} %This loads the eight-pointed asterisk.
\usepackage{graphicx} %This loads commands that flip iota for definite descriptions, Lambda for the universal class, and so on. The (superseded) graphics package should also work here, but is not recommended.

\title{\texttt{principia.sty}\\ A \LaTeXe \space Package for Typesetting Whitehead and Russell's \textit{Principia Mathematica} (Version 2.0)}
\author{Landon D. C. Elkind \texttt{landon.elkind@wku.edu}}
\date{\today}

\maketitle
\onehalfspacing
The \texttt{principia} package is designed for typesetting the Peanese notation of \textit{Principia Mathematica}. ``Peanese'' is something of a misnomer: Whitehead and Russell invented much of the notations used in \textit{Principia Mathematica} even while borrowing from many others.

\texttt{principia}'s style has antecedents in Kevin C. Klement's excellent \textit{Tractatus} typesetting, to which we owe the device of adding `d's and `t's to typeset further square dots. The device of beginning all \texttt{principia} commands with `\texttt{$\backslash$pm}' is owed to the \texttt{begriff} package, a style that was mimicked in both the \texttt{frege} package and the \texttt{Grundgesetze} package. 

In \textit{Principia Mathematica} some symbols occur with an argument and sometimes that same symbol occurs without an argument. For example, `$\pmsome{x}$' occurs in some formulas, but sometimes `$\pmSome$' occurs in the text when they talk about the symbol itself. \texttt{principia} is designed to accommodate these different occurrences of symbols. When a symbol is to occur without an argument, capitalize the first letter following the `\texttt{$\backslash$pm}' part of the command. E.g. \verb|\pmsome{x}| produces $\pmsome{x}$ and \verb|\pmSome| produces `$\pmSome$'. Note the former command requires an argument and the latter command does not. Not all commands in the \texttt{principia} package admit of such dual use because some symbols in \textit{Principia Mathematica} never occur without an argument or do not take an argument in the usual sense. For example, the propositional connectives do not take an `argument' in the way singular or plural descriptions do.

Version 2.0 of \texttt{principia} is adequate to typeset all notations throughout Volumes I-III of \textit{Principia} and includes some minor fixes. Below are commands for Volume I.

\texttt{principia}'s dependencies are \texttt{amsmath}, \texttt{amssymb}, \texttt{pifont}, and \texttt{graphicx}. Make sure to load these package by typing \texttt{$\backslash$usepackage\{graphicx\}}, etc., into the document preamble. 

To load \texttt{principia}, type \texttt{$\backslash$usepackage\{principia\}} in the document's preamble.
