The second option is that, if every finite mind ceased to think about an eternal truth for a time, then for however long it remained unthought of by finite minds the eternal truth would have no reality at all, that is, it would quite literally be nothing. This presumably means that it would, for that time, not be true at all. But it is absurd to suppose that there might be a time when ‘2 + 2 = 4’ (for example) ceases to be true, no matter how brief that time might be.
