The verse environment looks good to me for highlighting and referencing a paragraph. However, I don't like that it automatically indents what doesn't fit in an ongoing line. I would like the overall thing to be indented, but no additional indentation for everything following line one.
\documentclass[a4paper, 12pt, twoside=on]{scrreprt}
\begin{document}
\begin{verse}
\label{HeisenbergVsObserver}
The uncertainty principle, however, states that there is a fundamental limit to how objectively well-defined these two non-commuting observables can be at any given time.
\end{verse}
\end{document}
results in:
As an aside: what do I have to do for stackexchange to compile and show the output of the latex document:
\documentclass[a4paper, 12pt, twoside=on]{scrreprt}
\begin{document} \begin{verse} \label{HeisenbergVsObserver} The uncertainty principle, however, states that there is a fundamental limit to how objectively well-defined these two non-commuting observables can be at any given time. \end{verse} \end{document}
epigraph
package may be more appropriate for this sort of inclusion.\setlength\epigraphwidth{.93\textwidth}
and\setlength{\epigraphrule}{0pt}
, but now it looks fine though I like the typesetting of verse more. Also, epigraph doesn't stretch characters out till the end of the line.
