I am looking for a phrase, I believe it may be latin. I know the meaning I'm looking for but not the words that convey it. Any help you might be able to give will be appreciated. The definition of the phrase is something on the order of 'it looks too good not to be true' meaning that the proposition put forth, though not supported by evidence, seems so reasonable that no further thought goes into it, even though the proposition might be false, hinting that common wisdom is no wisdom at all. Anyone know?
