IT really really bugs me all day that I can't remember the words!!!

<p>So, from Plato, it talks about different types of arguments and the characteristics of them.
One is “argument for argument’s sake”
the other one(ideal one) is “argument for solution or conclusion.”</p>

<p>and I KNOW that there is a word for each “argument for argument’s sake” and for “argument for solution or conclusion.” BUT I can’t remember them! It really bugs me…</p>

<p>The word is not "rhetorical…didactic…''OMG I can’t remember! can somebody please help me!</p>

<p>dialectic?</p>
