like—­here we have no test external to ourselves, no authority superior and independent.  Invite a group of men to witness a scientific experiment, and none of them will be able to deny either the sequence of the phenomena produced, or the chain of reasoning (supposing it to be sound) which leads to the conclusion based upon them.  Invite the same men to judge of a picture, or consult them on a question of moral casuistry, and they will propound the most opposite opinions; nor will there be any objective test by which you can affirm that one opinion is more correct than another.  The deliverances of the external sense are, or at least can be made, by correction of the personal equation, infallible and the same for all; those of the internal sense are different not only in different persons, but in the same person at different times.”

“Yes,” said Leslie, impatiently, “we have all admitted that!  The question is whether—­”

“Excuse me,” Wilson interposed, “I haven’t yet come to my main point.  I was going to say that not merely are there these differences of opinion, but even if there were not, even if the opinions were uniform, they would still, as opinions, be subjective and devoid of scientific validity.  It is the external reference that gives its certainty to science; and such a reference is impossible in the case of judgments about the Beautiful and the Good.  Such judgments are merely records of what we think or feel.  These ideas of ours may or may not happen to be consistent one with another; but whether they are so or not, they are merely our ideas, and have nothing to do with the essential nature of reality.”

“I am not sure,” I replied, “that the distinction really holds in the way in which you put it.  Let us take for a moment the point of view of God—­only for the sake of argument,” I added, seeing him about to protest.  “God, we will suppose, knows all Being through and through as it really is; and along with this knowledge of reality he has a conviction that reality is good.  Now, with this conviction of his none other, ex hypothesi, can compete; for he being God, we must at any rate admit that if anybody can be right, it must be he.  No one then can dispute or shake his opinion; and since he is eternal he will not change it of himself.  Is there then, under the circumstances, any distinction of validity between his judgment that what is, is, and his judgment that what is, is good?”

“I don’t see the use,” he replied, “of considering such an imaginary case.  But if you press me I can only say that I still adhere to my view that any judgment about Good, whether made by God or anybody else, can be no more than a subjective expression of opinion.”
