Hi there,
I know that "only if" is a necessary condition indicator, but I'm wondering if "if only" would also be a necessary condition indicator or if it is a sufficient indicator? If "if only" is a sufficient indicator, then how does it differ from "only if"?
I've also been having a bit of trouble wrapping my head around the difference between sufficient and necessary conditions. I know the standard definitions and the traditional if-then explanation but none of these have lead to a click style moment of realization for me. I have gotten it down pat that if-then and such does represent a sufficient and necessary condition, but how exactly does the one differ from the other? The explanations in the Powerscore Bibles do not seem to be helping me understand the critical difference.
A recent question where I made a mistake was "the only way to achieve success is to work hard" I understand now that the "way" is referring to work hard which so work hard is the sufficient condition. If I put this statement into and if-then format I'll get "if I work hard then I will achieve success" but if I did the reverse which is incorrect I would get "if I achieve success then I will work hard." How do these differ though? I seem to be messing up then which portion is the necessary and which is the sufficient a lot even when I use if-then form to phrase things. Feel free to use other examples to explain as well!
