如何缩进块引用中的段落？

Question

我必须写一个跨段落的块引用。《芝加哥格式手册》第 17 版似乎建议（在 13.22 中）块引用中的新段落应使用缩进。

但是，每当我尝试在新行上使第二个段落以缩进开头时，我的 LaTeX 编辑器 (Overleaf) 都会拒绝添加缩进。我尝试了以下四种方法，但似乎都不起作用：

\begin{quote}
This is the first paragraph.
\newline\indent I want this to have an indent.
\end{quote}

\begin{quote}
This is the first paragraph.
\newline\tab I want this to have an indent.
\end{quote}

\begin{quote}
This is the first paragraph.
\newline\hspace{\parindent} I want this to have an indent.
\end{quote}

\begin{quote}
This is the first paragraph.
\newline ~~~~I want this to have an indent.
\end{quote}

我如何实现我的目标？

使用quotation环境，而不是quote，并用空行分隔环境内的段落。无需手动添加缩进。

\documentclass{article}

\begin{document}
Text before quotation.

\begin{quotation}
  This is the first paragraph.
  This is the first paragraph.
  This is the first paragraph.

  This is the second paragraph.
  This is the second paragraph.
  This is the second paragraph.
\end{quotation}

Text after quotation.
\end{document}

以下是我尝试从文章类修改引用环境：

\documentclass{article}

\makeatletter
\renewenvironment{quotation}
               {\list{}{\listparindent 1.5em%
                        \rightmargin   \leftmargin
                        \parsep        \z@ \@plus\p@}%
                \item\relax}
               {\endlist}
\makeatother

\begin{document}
Text before quotation.

\begin{quotation}
  This is the first paragraph.
  This is the first paragraph.
  This is the first paragraph.

  This is the second paragraph.
  This is the second paragraph.
  This is the second paragraph.
\end{quotation}

Text after quotation.
\end{document}
