Ex Falso Quodbilet or the principle of explosion is that from a false/contradiction we can derive any proposition; that is $\bot \vdash A$.
Dually, do we have from any proposition we can derive truth, that is $A \vdash \top$? If so does it have name?
@ToddTrimble I see that you have joined the discussion on meta about that question. If I may ask, what do you think about creation of the new tag for the question? Wouldn't terminology be a reasonable replacement for nomenclature?
