Ingratitude is abhorred by God and man.

Some natures are so sour and ungrateful that they are never to be obliged.

To be longing for this thing to-day and for that thing to-morrow; to change likings for loathings, and to stand wishing and hankering at a venture--how is it possible for any man to be at rest in this fluctuant, wandering humor and opinion?

A plodding diligence brings us sooner to our journey's end than a fluttering way of advancing by starts.

Intemperate wits will spare neither friend nor foe, and make themselves the common enemies of mankind.

Men indulge those opinions and practices that favor their pretensions.

There is no opposing brutal force to the stratagems of human reason.
