I took Gonzalo Medina's second solution in his answer to "Inspirational" quote at start of chapter and changed the following:
Instead of using the memoir class, the epigraph package (from memoirs author) is loaded;
\epigraphfontsize is replaced with \epigraphsize;
The etoolbox package is used to patch the internal \@epitext command so that \itshape works.
\documentclass{article}
\usepackage{epigraph}
% \epigraphsize{\small}% Default
\setlength\epigraphwidth{8cm}
\setlength\epigraphrule{0pt}
\usepackage{etoolbox}
\makeatletter
\patchcmd{\epigraph}{\@epitext{#1}}{\itshape\@epitext{#1}}{}{}
\makeatother
\begin{document}
\section{Graph Theory}
\epigraph{``Begin at the beginning," the King said gravely, ``and go on till you come to the end: then stop."}{--- \textup{Lewis Carroll}, Alice in Wonderland}
\end{document}

quote environment because it might be needed for block quotes in the text body. BTW, quote uses a width of somehat less than 100%, and in my example you may change the value of the \epigraphwidth length.

epigraph package offers an epigraphs environment where you write individual quotes using \qitem-- have a look at the manual.
