Well, the course in logic that I took was only one semester and it was a long while ago but, iirc, assumptions are the basis of all logical arguments whether factual or hypothetical.
CriticalThinking.org Wrote:"An assumption is something we take for granted or presuppose. Usually it is something we previously learned and do not question. It is part of our system of beliefs. We assume our beliefs to be true and use them to interpret the world about us. If we believe that it is dangerous to walk late at night in big cities and we are staying in Chicago, we will infer that it is dangerous to go for a walk late at night."From this page.
An assumption is not inherently fallacious or flawed, it's merely something which is assumed to be true; in this case it's assumed "for the sake of argument" meaning "this probably isn't true, but if it were, would the following inferences make sense?"
