I will show you how I found what is the problem. Just to see what's going
on, I have created a testing document just with questionable string, like
this:

\documentclass{article}
\begin{document}
        Aristotle's Notion of Potentiality in {\emph {Metaphysics}} 
        \Theta
\end{document}

What is the result when I try to compile it?

/home/matej/test.tex|4 error| Missing $ inserted. $ \Theta 
/home/matej/test.tex|5 error| Missing $ inserted. $ \end{document}

Chmm, sounds intrguiging -- $ is beginning/end of math-mode. So, what LaTeX
wants to tell you here is that \Theta is available only in the mathematical
mode (so LaTeX tried to insert $s around the sign). What happens when we
try to insert $ manually?

\documentclass{article}
\begin{document}
        Aristotle's Notion of Potentiality in {\emph {Metaphysics}} 
        $\Theta$
\end{document}

And everything is perfect. Easy, isn't it?
