Friendship, on the other hand, serves a great host of different purposes all at the same time. In whatever direction you turn, it still remains yours. No barrier can shut it out. It can never be untimely; it can never be in the way. We need friendship all the time, just as much as we need the proverbial prime necessities of life, fire and water.
Marcus Tullius CiceroFor while we are enclosed in these confinements of the body, we perform as a kind of duty the heavy task of necessity; for the soul from heaven has been cast down from its dwelling on high and sunk, as it were, into the earth, a place just the opposite to godlike nature and eternity. But I believe that the immortal gods have sown souls in human bodies so there might exist beings to guard the world and after contemplating the order of heaven, might imitate it by their moderation and steadfastness in life.
Marcus Tullius Cicero
