One great function of poetry is to keep open the road which leads from the seen to the unseen world, and as the last echoes of this noble poem die away, it would seem as though a door had been opened in heaven and an unearthly vision had been revealed to our wondering eyes. It is as though some strange inspiration had fallen upon one suddenly, like that which the seer in the Apocalypse felt when he said, "And immediately I was in the spirit". The truth is we have been led into the invisible world, we have gained with the poet "a sense of God". The strange, undefinable attraction of the infinite is upon us. Perhaps we have not yet learnt how strong that fascination is; how that it is not only the source of that inner light which we see reflected in the countenance of the philosopher and saint, but that it is powerful to arrest the attention of men who are for ever saying that no such reality exists, or, that even if it does, man need no more concern himself about it. Has he not the solid earth and the realm of sense? Why should he seek what is beyond it? _O caecas hominum mentes_! Man cannot help himself. Well does the ethic master say, "What is the use of affecting indifference towards that about which the mind of man never can be indifferent?" And why not? Because man came thence? There is that in us "which drew from out the boundless deep". In some incomprehensible way the infinite is in us, and we are therefore restless, dissatisfied ultimately with all that is not it. "The eye is not filled with sight nor the ear with hearing," for in us there is the capacity, and therefore, in our best moments, the yearning to see and hear something which sense can never give. Greater than all that is here, in silent moments, when the senses are tired and disappointment steals over us, the truth of the insignificance of things bursts upon us. "Man is but a reed, the feeblest thing in nature," says Pascal in the _Pensees_, "but he is a thinking reed. The universe need not mass its forces to accomplish his destruction. A breath, a drop of water may destroy him. But even though the world should fall and crush him he would still be more noble than his destroyer because he knows that he dies, but the advantage which the world possesses over him--of that the world knows nothing." And, therefore, the universe is nothing to him who is conscious that there is that in man which made all worlds and shall unmake them--the eternal Mind, one and identical throughout the realm of intelligence.
