There would be no childlike faith then, no poetry, no romance to make tolerable this existence. We would have no enjoyment, except in sense and sight. The eternal light with which childhood fills the world would be extinguished. Nobody sees Santa Claus but that is no sign that there is no Santa Claus. The most real things in the world are those that neither children nor men can see.
Nobody can conceive or imagine all the wonders there are unseen and unseeable in the world.
You may tear apart the baby's rattle and see what makes the noise inside, but there is a veil covering the unseen world which not the strongest man, nor even the united strength of all the strongest men that ever lived, could tear apart. Only faith, fancy, poetry, love, romance, can push aside that curtain and view, and picture the supernal beauty and glory beyond. Ah, Virginia, in all this world, there is nothing else real and abiding. Thank God, he lives, and he lives forever. A thousand years from now, Virginia, nay 10 times 10,000 years from now, he will continue to make glad the heart of childhood.
