 Suárez seems to have conceded a great deal to the critics of final causation in allowing that every final cause remains at root implicated in the realm of the intentional. Still, again, he makes this concession only by way of affirming the existence of final causes. He has thereby also, however, evidently maneuvered himself into an uncomfortable position whereby the Fountain of Youth, for instance, is a final cause, even though it has no real being (esse reale). Yet he himself insists that nothing is a cause, or principium in general, without having real being. He thus owes an explanation of how he avoids falling into a direct contradiction on this point. The Fountain of Youth cannot both lack real being and be a cause, of any kind.
