%\section{Introduction}
%\label{sec:intro}
%
% As said in its mission statement at
% \url{http://www.philosophersimprint.org}, ``\emph{Philosophers'
%   Imprint} is a refereed series of original papers in philosophy,
% edited by philosophy faculty at the University of Michigan, with the
% advice of an international Board of Editors, and published on the
% World Wide Web by the University of Michigan Digital Library. The
% mission of the Imprint is to promote a future in which funds
% currently spent on journal subscriptions are redirected to the
% dissemination of scholarship for free, via the Internet.''  The
% journal used to accept manuscripts in Rich Text Format only.
% However, for many authors, especially from the field of logic,
% \TeX{} seems to be a better choice.  I was commissioned to write a
% \LaTeX{} class for this journal. 
%
% The aim of the class is to help authors to typeset their own
% articles in the ``Web-ready'' format.  We do not assume the authors
% have any commercial fonts installed on their machines.  The class
% uses only freely available and freely distributed fonts.  This
% presents some difficulties since the journal is usually typeset in
% Adobe Palatino.  We use the Palladio and Pazo fonts and (for the
% title) Trajan font.
%
%
%\section{User Interface}
%\label{sec:interface}
%
%
%\subsection{Invocation and Options}
%\label{sec:options}
%
% To use the class put in the preamble of your document
% \begin{flushleft}
% |\documentclass[|\meta{options}|]{philosophersimprint}| 
% \end{flushleft}
%
% The class is intended to be used with \progname{pdflatex}.  If you compile
% DVI output instead (for example, to use with \progname{PSTricks}), the class
% generates a warning.
%
% The class \progname{philosophersimprint} internally loads \progname{article},
% and therefore all 
% class options for \progname{article} are technically valid.  However, most of
% them are not especially meaningful for \progname{philosophersimprint}.
% There are several options specific for this class.  They are
% described below
%
% \DescribeOptions{titleimage,notitleimage} 
% The editorial board of \emph{Philosophers' Imprint} prefers to
% typeset the titlepage itself and provide it as a PDF document to the
% authors. If you have such titlepage, use the |titleimage| option
% (default).  Otherwise use the |notitleimage| option, and the class
% will make a (half-hearted) attempt to create a simulated title page
% for you.  If |titleimage| option is chosen, but \LaTeX{} cannot find
% the titlepage image, the class generates a warning and switches to
% the |notitleimage| behavior.
%
% Note that even if you do have a titlepage image, you still need to
% invoke top matter macros |\title|, |\authors| etc.  to supply
% information for running heads and PDF metadata (see
% Section~\ref{sec:topmatter}). 
%
%
% \DescribeOptions{trajantitle, notrajantitle}
% If the option |trajantitle| is chosen (default), a beautiful Trajan
% font~\cite{Wilson05:Trajan} will be used to typeset the title of
% the paper.  Of course, this option has an effect only if
% |notitleimage| option is selected.  Note that this font has no
% Arabic numbers, so if your title needs numbers, use Roman numerals
% instead.  If you do not have |trajan.sty| on your system, the class
% will revert to Palatino in the title.
%
% \DescribeOptions{nosc,noosf}
% By default the class uses \progname{mathpazo} package with the
% options |sc| and |osf|.  These options provide improved fonts with
% true small caps and old style figures
% (see~\cite{Schmidt04:PSNFSS9.2}).   If you have the recent PSNFSS
% fonts that include free FPL collection~\cite{Stubner05:FPL}, you
% should not change this behavior.  Otherwise you probably would be
% better off by upgrading.  Only if you definitely cannot use these
% fonts, select the |nosc| and |noosf| options.  
%
% \DescribeOptions{slantedGreek,noBBpl}
% The options |slantedGreek| and |noBBpl|, if present, are passed to
% \progname{mathpazo} package.  See~\cite{Schmidt04:PSNFSS9.2} for the
% discussion of these options.
%
% \DescribeOptions{flushend,noflushend}%
% The options |flushend| and |noflushend| (default) determine the look
% of the last page of the article.  If the option |flushend| is
% chosen, the last page has balanced columns, while the opposite
% option makes them unbalanced.  Usually you should not balance the
% columns if you have footnotes on the last page.
%
%\subsection{Topmatter}
%\label{sec:topmatter}
%
% Topmatter is the part of the article with the informations about the
% authors, their affiliations, the publication data, etc.
%
% The standard \LaTeX{} topmatter macros are insufficient for most
% journals, and many journal styles like |amsart| or |elsart| use
% their own more or less sophisticated conventions.  Since the
% editorial board of \emph{Philosophers' Imprint} prefers to provide
% its own title pages, we chose to implement a rather simple set of
% topmatter macros, sufficient to generate a sample title page, while
% expecting the official one.  
%
% Note that even if you do have the ``official'' title page, you still
% need to use these macros because they are used for running heads and
% for PDF metadata.
%
% \DescribeMacro{\titleimage}
% The macro |\titleimage| has one argument:  the name of the file with
% the official title page image:
% \begin{flushleft}
%   |\titleimage{|\meta{FileName}|}|
% \end{flushleft}
% for example, |\titleimage{1stpage.pdf}|.  If the file is absent, the
% class issues a warning and tries to typeset a simulated page.
%
% \DescribeMacro{\title}
% The |\title| command has two arguments:  one mandatory argument and
% one optional:
% \begin{flushleft}
%   |\title[|\meta{ShortTitle}|]{|\meta{FullTitle}|}|
% \end{flushleft}
% The mandatory argument is the full title of the article.  The
% optional argument, if present, sets the shorter version of the title
% for running heads.  If the optional argument is absent, the full
% title is used instead.
%
% \DescribeMacro{\author}
% The |\author| command also has two arguments with the similar
% meaning: 
% \begin{flushleft}
%   |\author[|\meta{ShortListOfAuthors}|]{|\meta{FullListOfAuthors}|}|
% \end{flushleft}
% The optional argument is used for the running heads.  If it is
% absent, the full list of authors is used there.
%
% Separate multiple authors with commas.  Do \emph{not} use \LaTeX{}
% command |\and|.
%
% \DescribeMacro{\affiliation}
% The |\affiliation| command sets the affiliation of the authors:
% \begin{flushleft}
%   |\affiliation{|\meta{Affiliation}|}|
% \end{flushleft}
% Use |\\| to separate different affiliations.
%
% \DescribeMacro{\date}
% The command |\date| is similar to the standard \LaTeX{} command.
% However, remember that the date format is different:  ``Month,
% year'', e.g.
% \begin{flushleft}
%   |\date{April, 2007}|
% \end{flushleft}
% It should be also noted that the date here is the date of
% publication.
%
% \DescribeMacro{\journalvolume}\DescribeMacro{\journalnumber}
% The macros |\journalvolume| and |\journalnumber| set the volume and
% number of the journal where the article is published:
% \begin{flushleft}
%   |\journalvolume{7}|\\
%   |\journalnumber{4}|
% \end{flushleft}
% You will receive these data from the editorial office once your
% article is accepted.  
%
% \DescribeMacro{\copyrightinfo} The macro |\copyrightinfo| is
% used to store the copyright date and copyright holder of the
% article, like
% \begin{flushleft}
%   |\copyrightinfo{1724, Immanuel Kant}|
% \end{flushleft}
% Note that the package does \emph{not} try to deduce the copyright
% information from the date and author list.  You need to set it
% explicitly. 
%
% \DescribeMacro{\copyrightlicense}
% By default all papers in the journal are licensed under
%  under a Creative Commons
%  Attribution-NonCommercial-NoDerivatives 3.0 License.  You can
%  override this setting by using \cmd{\copyrightlicense}\marg{Other
%  license}. 
%
%
% \DescribeMacro{\subject}
% This macro, if present, sets the ``Subject'' field in the PDF
% metadata.  For example:
% \begin{flushleft}
%   |\subject{Ethics}|
% \end{flushleft}
%
% \DescribeMacro{\keywords}
% The macro |\keywords| is similar to |\subject|, but accepts a comma
% separated list of keywords.  If present, they will be used in the
% ``Keywords'' field of the PDF document.
%
%
%\subsection{Required and Recommended Software}
%\label{sec:packages}
%
% To typeset articles for \emph{Philosophers' Imprint,} you need the
% proper fonts.  PSNFSS version~9.2 or
% later~\cite{Schmidt04:PSNFSS9.2} with URW and FPL fonts are
% recommended.  It is easy to check whether you have these fonts:  if
% you do not, then besides warnings in the log file, you will see
% headers and footers in lower case instead of correct small caps.
% Also, the numbers will be typeset with lining figures instead of old
% style numbers.
%
% The class also uses packages \progname{color} and
% \progname{graphicx} from the graphics
% bundle~\cite{Carlisle05:Graphics} to typeset the title page.
%
% Package \progname{ifpdf}~\cite{Oberdiek06:Ifpdf} is used to check
% whether PDF output is selected.
%
% Package \progname{fancyhdr}~\cite{Oostrum04:Fancyhdr} is used to set
% up running headers and footers.
%
% You need the packages above for the document written in
% \progname{philosophersimprint} class to compile.  The packages below are not
% strictly necessary, but highly recommended.
%
% Package \progname{hyperref}~\cite{Rahtz06:Hyperref} is used to set
% up PDF metadata and make the links ``clickable''.  We did not
% include it in the list of required packages, because it prefers to
% be loaded last, and we wanted to give the user a chance to load her
% own packages.  We recommend the following options:
% \begin{verbatim}
% \usepackage[breaklinks,colorlinks,linkcolor=black,citecolor=black,
%              pagecolor=black,urlcolor=black]{hyperref}
% \end{verbatim}
% See |sample.tex| for the example of the usage of this
% package. 
%
%
% The authors of \emph{Philosophers' Imprint} use both bibliography at
% the end of the article and bibliographic references in footnotes.
% The packages \progname{natbib}~\cite{Daly07:Natbib} and
% \progname{opcit}~\cite{Garcia06:Opcit} are recommended for
% formatting the bibliography with \BibTeX.  However, these packages
% are \emph{not} loaded by the class;  it is the responsibility of the
% author to load and use them.
%
%
%\subsection{Configuration File}
%\label{sec:conffile}
%
% If the file \path{philosophersimprint.cfg} exists, it will be read by the
% class.  It is a good place to put, for example, the default
% options. 
%
%
%\subsection{Some Fine Points}
%\label{sec:fine_points}
%
% The journal prefers the baselines of both columns to be aligned.
% This is a famous problem of ``typesetting to a grid''.  Generally
% speaking, this is not trivial in a \TeX{} world (see a discussion
% of this problem in~\cite{Bazargan07:VertStretch}).  Normally, \TeX{}
% stretches distances between the baselines to achieve homogeneous
% grayness of the page.  It takes some effort to switch this behavior
% off. 
%
% This class deletes most of \TeX{} vertical stretchability.  If there
% is much mathematics in the copy it might lead to some really ugly
% results.  However, when the texts are not too heavy on math, the
% class can do a decent job.  Below we list some cases where it
% cannot, and some manual intervention is warranted
% (see~\cite{Bazargan07:VertStretch} for a description of an automatic
% solution.  Unfortunately, at the moment of writing this version,
% this solution was not available as a free software).
% \begin{enumerate}
% \item We add 3/4 baseline leading before section title and 1/4
% baseline leading after.  This means that if a section starts a
% column, the baselines will be different by 1/4.  An insertion of
% |\vspace*{-0.25\baselineskip}| sometimes leads to acceptable
% results.
% \item We add 1/2 baseline leading before and after structures like
%   quotations, theorems, corollaries etc.  If such structure is
%   split between columns, this breaks alignment.  Again, a manual
%   intervention might help.
% \item We do not try to control the vertical space of structures,
% added, for example, by |\includegraphics| commands.
% \item Sometimes a displayed equation can lead to breaking
% alignment. 
% \end{enumerate}
% 
% In most cases the amount of manual intervention necessary to
% achieve alignment is fairly small. 
%
% In some cases one can achieve better results by tweaking \TeX\
% parameters.  For example, the settings
% \begin{verbatim}
% \clubpenalty=1000\widowpenalty=1000\displaywidowpenalty=1000
% \interfootnotelinepenalty=-1000
% \interlinepenalty=-100
% \end{verbatim}
% may lead to fuller pages, but may produce some unwaned orphans and
% clubs.  Setting them to
% \begin{verbatim}
% \clubpenalty=10000\widowpenalty=10000\displaywidowpenalty=10000
% \interfootnotelinepenalty=0
% \interlinepenalty=0 
% \end{verbatim}
% will decrease the number of orphans and clubs, but may lead to
% unwanted white spaces on the pages.  Sometimes judicious changes of
% the parameters in strategic places may help.
