It is ingrained in all living creatures, first of all, to preserve their own safety, to guard against what is harmful, to strive for what is advantageous.
AmbroseBlessed, plainly, is that life which is not valued at the estimation of outsiders, but is known, as judge of itself, by its own inner feelings. It needs no popular opinions as its reward in any way; nor has it any fear of punishments. Thus the less it strives for glory, the more it rises above it. For to those who seek for glory, that reward in the shape of present things is but a shadow of future ones, and is a hindrance to eternal life, as it is written in the Scriptures: 'Truly I say to you, they have received their reward'
AmbroseMay each one of us glorify the Lord with the soul of Mary and rejoice in God with the spirit of Mary
AmbroseHow far, O rich, do you extend your senseless avarice? Do you intend to be the sole inhabitants of the earth? Why do you drive out the fellow sharers of nature, and claim it all for yourselves? The earth was made for all, rich and poor, in common. Why do you rich claim it as your exclusive right?
Ambrose
