It is not by muscle, speed, or physical dexterity that great things are achieved, but by reflection, force of character, and judgment.

The process, indeed, of nature is this: that just in the same manner as our birth was the beginning of things with us, so death will be the end; and as we were noways concerned with anything before we were born, so neither shall we be after we are dead.
