No animal admires another animal.

Reflect on death as in Jesus Christ, not as without Jesus Christ. Without Jesus Christ it is dreadful, it is alarming, it is the terror of nature. In Jesus Christ it is fair and lovely, it is good and holy, it is the joy of saints.

The secrets of nature are concealed; her agency is perpetual, but we do not always discover its effects; time reveals them from age to age; and although she is always the same in herself, she is not always equally well known.

All the trouble in the world is due to the fact that man cannot sit still in a room.

To deny, to believe, and to doubt well, are to a man what the race is to a horse.

Those honor nature well, who teach that she can speak on everything...

When we wish to correct with advantage, and to show another that he errs, we must notice from what side he views the matter, for on that side it is usually true.
