How can I skip sections in the numbering?

Question

I have the following latex file:

\documentclass{article}
\begin{document}
\section{First}
% Content for the first section
\section{Second}
% Content for the second section
\section{Third}
% Content for the third section, which will be numbered as 1 in the PDF
\section{Fourth}
% Content for the fourth section, which will be numbered as 2 in the PDF
\end{document}

By default, I get the following output:

1. First
2. Second
3. Third

But what I want is:

• First
• Second
• 1. Third

How can I achieve this?
