Augustine of Hippo

Thou hast made us for thyself, O Lord, and our heart is restless until it finds its rest in thee.

The present of things past is memory; the present of things present is sight; and the present of things future is expectation.

Great is this force of memory, excessive 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.
