The best preservative to keep the mind in health is the faithful admonition of a friend.
Francis BaconThe human understanding, from its peculiar nature, easily supposes a greater degree of order and equality in things than it really finds.
Francis BaconThe true bounds and limitations, whereby human knowledge is confined and circumscribed,... are three: the first, that we do not so place our felicity in knowledge, as we forget our mortality: the second, that we make application of our knowledge, to give ourselves repose and contentment, and not distates or repining: the third, that we do not presume by the contemplation of Nature to attain to the mysteries of God.
Francis Bacon
