That pink word, there. That's an important word, and, given the volume of your questions here as well as your (
you = woohoo921) generally solid level of basic understanding, I trust that you already have a fundamental understanding of what assumptions are—especially given their position of immense importance, at the center of a whole class of CR problems.
Perhaps, however, the CR Assumption question type has distracted you from the much wider overall scope of assumptions.
CR assumptions problems ask, "Which of these MUST be an assumption?" That's a VERY strong condition. The result is that the assumptions that correctly answer CR assumption problems are all ABSOLUTELY NECESSARY assumptions, which most real-life assumptions are pointedly not.
•
Assumptions are, by definition, NOT STATED.
• CR Assumption problems ask for assumptions that are ABSOLUTELY NECESSARY, by rigorous formally logical standards.To be
absolutely necessary, an assumption must not only hew to the exact precise subset of specific
content that the discussion needs, but also
MUST be stated in the weakest (most modest; least broad) possible terms (Anything stronger than the minimum, even by only a tiny margin, is no longer ABSOLUTELY NECESSARY because it can be diluted into the even weaker absolute minimum version while remaining fit for purpose.)
The thing is, though, that THE WORD "ASSUMPTION" IN GENERAL does not carry either of the two very exacting mandates that
NECESSARY assumptions must fulfill.
In general, assumptions are almost totally open-ended (barring explicit contradictions of given info), because nothing is stopping anybody from importing 17 different weird ideas into innocuous conversations.
Thus,
• NECESSARY assumptions—the type that constitute the goal in CR assumption problems—are only a tiny tiny fraction of all assumptions.
Generally, "assumption" means "a thing that someone just made up, inserted herself/himself into the dialogue/discussion, and ran with it".
Assumptions limned by random people may or may not be true. But,
an author who writes about some other person's assumptions does not own them, and is not stating them, AT ALL—nor can you represent assumptions in general as true (unless they are NECESSARY assumptions).
