Manners are stronger than laws

Laws control the lesser man. Right conduct controls the greater.

It is love, not reason, that is stronger than death.

With nanotechnology, you can produce steel that's 100 times stronger but six times lighter.

For if you suffer your people to be ill-educated, and their manners to be corrupted from their infancy, and then punish them for those crimes to which their first education disposed them, what else is to be concluded from this, but that you first make thieves and then punish them.

Good manners: The noise you don't make when you're eating soup.
