needed a particular sort of mind to see that there was anything poetical about the skylark or the spring. That mind was presumably what we call the human mind, very much as it exists to this day; for mystics still meditate upon death and dreams as poets still write about spring and skylarks. But there is not the faintest hint to suggest that anything short of the human mind we know feels any of these mystical associations at all. A cow in a field seems to derive no lyrical impulse or instruction from her unrivalled opportunities for listening to the skylark. And similarly there is no reason to suppose that live sheep will ever begin to use dead sheep as the basis of a system of elaborate ancestor-worship. It is true that in the spring a young quadruped’s fancy may lightly turn to thoughts of love, but no succession of springs has ever led it to turn however lightly to thoughts of literature. And in the same way, while it is true that a dog has dreams, while most other quadrupeds do not seem even to have that, we have waited a long time for the dog to develop his dreams into an elaborate system of religious ceremonial. We have waited so long that we have really ceased to expect it; and we no more look to see a dog apply his dreams to ecclesiastical construction than to see him examine his dreams by the rules of psycho-analysis. It is obvious, in short, that for some reason or other these natural experiences, and even natural excitements, never do pass the line that separates them from creative expression like art and religion, in any creature except man. They never do, they never have, and it is now to all appearance very improbable that they ever will. It is not impossible, in the sense of self-contradictory, that we should see cows fasting from grass every Friday or going on their knees as in the old legend about Christmas Eve. It is not in that sense impossible that cows should contemplate death until they can lift up a sublime psalm of lamentation to the tune the old cow died of. It is not in that sense impossible that they should express their hopes of a heavenly career in a symbolical dance, in honour of the cow that jumped over the moon. It may be that the dog will at last have laid in a sufficient store of dreams to enable him to build a temple to Cerberus as a sort of canine trinity. It may be that his dreams have already begun to turn into visions capable of verbal expression, in some revelation about the Dog Star as the spiritual home for lost dogs. These things are logically possible, in the sense that it is logically difficult to prove the universal negative which we call an impossibility. But all that instinct for the probable, which we call common sense, must long ago have told us that the animals are not to all appearance evolving in that sense; and that, to say the least, we are not likely to have any personal evidence of their passing from the animal experience to the human experiments. But spring and death and
