If, now, we put this question, I cannot avoid thinking that it should receive an affirmative answer. We can put it clearly by the method of isolation; and the sole decision must rest with our reflective judgment upon it, as thus clearly put. We can guard against the bias produced by a consideration of value _as a means_ by supposing the case of an illusion as complete and permanent as illusions in this world never can be. We can imagine the case of a single person, enjoying throughout eternity the contemplation of scenery as beautiful, and intercourse with persons as admirable, as can be imagined; while yet the whole of the objects of his cognition are absolutely unreal. I think we should definitely pronounce the existence of a universe, which consisted solely of such a person, to be _greatly_ inferior in value to one in which the objects, in the existence of which he believes, did really exist just as he believes them to do; and that it would be thus inferior _not only_ because it would lack the goods which consist in the existence of the objects in question, but _also_ merely because his belief would be false. That it would be inferior _for this reason alone_ follows if we admit, what also appears to me certain, that the case of a person, merely imagining, without believing, the beautiful objects in question, would, _although these objects really existed_, be yet inferior to that of the person who also believed in their existence. For here all the additional good, which consists in the existence of the objects, is present, and yet there still seems to be a great difference in value between this case and that in which their existence is believed. But I think that my conclusion may perhaps be exhibited in a more convincing light by the following considerations. (1) It does not seem to me that the small degree of value which we may allow to the existence of beautiful inanimate objects is nearly equal in amount to the difference which I feel that there is between the appreciation (accompanied by belief) of such objects, when they really exist, and the purely imaginative appreciation of them when they do not exist. This inequality is more difficult to verify where the object is an admirable person, since a _great_ value must be allowed to his existence. But yet I think it is not paradoxical to maintain that the superiority of reciprocal affection, where both objects are worthy and both exist, over an unreciprocated affection, where both are worthy but one does not exist, does not lie solely in the fact that, in the former case, we have two good things instead of one, but also in the fact that each is such as the other believes him to be. (2) It seems to me that the important contribution to value made by true belief may be very plainly seen in the following case. Suppose that a worthy object of affection does really exist and is believed to do so, but that there enters into the case this error of fact, that the qualities loved,
