“Great is this force of memory, exceedingly great, O my God; a large and boundless chamber! Who ever sounded the bottom thereof? Yet is this a power of mine, and belongs unto my nature; nor do I myself comprehend all that I am. Therefore is the mind too limited to contain itself. And where should that be, which it containeth not of itself? Is it outside it, and not within? How then doth it not comprehend itself? A wonderful admiration surprises me. Amazement seizes me. And men go abroad to admire the heights of mountains, the mighty billows of the sea, the broad tides of rivers, the compass of the ocean, and the circuits of the stars, and pass themselves by.”

— St. Augustine
