Unwishable

1653, John Goodwin, An Exposition of The Ninth Chapter of the Epistle to the Romans, [1652, A Paraphrase], 1835, Baynes and Son, page 69, This interpretation, though it doth not suppose an eternal separation from Christ to be the matter of the Apostle's actual wish, at one time or other, or upon one consideration or other, wherein it differs from the former; yet it rendereth it as a thing wishable, or which the Apostle could and would wish, in case the two impediments specified, which render it de facto unwishable, were or could be removed out of the way.

Since it is his mother, the wish is unwishable, insupportable. How will he treat other women in the face of this unwishable wish?

Instead it begins in mid-wishing with a negative fulfilment, and it tails off without an end into an indefinite future of wishing for what the unwished-for knowledge has rendered unobtainable, unwishable.
