You can use the lstlisting environment from the listings package to do this. It is a verbatim environment, meaning that everything in it is printed exactly as written, including whitespace, braces, backslashes etc. You can configure it to allow for wrapping of long lines (breaklines=true), and set an indentation with xleftmargin=<length>.
This way you don't have add all the line breaks manually, and escape all the braces. On the other hand, words will not be hyphenated automatically, as they are in your quote.
\documentclass{article}
\usepackage{csquotes} % for comparison
\usepackage{listings}
\lstset{breaklines=true,
breakatwhitespace=false,
columns=flexible,
xleftmargin=2em}
