“It is enough to have been created, to have embodied for a moment the infinite and tumultuously creative spirit. It is infinitely more than enough to have been used, to have been the rough sketch for some perfected creation.”

My Reviewers Reviewed (lecture from June 27, 1877, San Francisco, CA)
Context: 23. “But the Lord thy God shall deliver them unto thee, and shall destroy them with a mighty destruction, until they be destroyed. 24. “And he shall deliver their kings into thine hand, and thou shalt destroy their name from under heaven; there shall no man be able to stand before thee, until thou have destroyed them.”— Deut. Vii. If these words had proceeded from the mouth of a demon, if they had been spoken by some enraged and infinitely malicious fiend, I should not have been surprised. But these things are attributed to a God of infinite mercy.

I believe in a lofty form of poetry, in the work in which beauty will be mingled with beliefs. The more incapable of it I feel myself, the more I believe it to be possible. The sad splendour with which certain memories of mine overwhelm me, shows me that it is possible. Sometimes I myself have been sublime, I myself have been a masterpiece. Sometimes my visions have been mingled with a thrill of evidence so strong and so creative that the whole room has quivered with it like a forest, and there have been moments, in truth, when the silence cried out.
But I have stolen all this, and I have profited by it, thanks to the shamelessness of the truth revealed. At the point in space in which, by accident, I found myself, I had only to open my eyes and to stretch out my mendicant hands to accomplish more than a dream, to accomplish almost a work.

Si hubiera estado presente en la Creación, habría dado algunas indicaciones útiles.
After studying Ptolemy's treatise on astronomy.; reported in Thomas Carlyle, History of Frederick the Great, book ii. chap. vii. Carlyle wrote that this saying of Alfonso about Ptolemy's astronomy, "that it seemed a crank machine; that it was pity the Creator had not taken advice," is still remembered by mankind, — this and no other of his many sayings.
If the Lord Almighty had consulted me before embarking on creation thus, I should have recommended something simpler.
