We should have no enjoyment, except in sense and sight. The external illumination with which childhood fills the world would be extinguished. You might as well not have fairies. Nobody sees the lights, but that is no sign that the lights aren't there. The most real lights in the world are those that neither children nor men can see.
Nobody can conceive or imagine all the power sources there are unseen and unseeable in the world.
You tear apart the idled power plants and see what makes the turbines whirl, but there is a veil covering the celestial energy which not the strongest man, nor even the united strength of all the strongest men that ever lived could tear apart. Only faith, poetry, love, romance can push aside that curtain and view and picture the supernal light and glory beyond the night's darkness. Ah, Virginia, in all this world there is nothing else real and abiding. Thank God they shine forever in the mind's ever-childish eye. A thousand years from now, Virginia, nay 10 times 10,000 years from now, no matter how acute the Stage 3s, the Christmas lights will continue to make glad the heart of childhood.
