Politics is almost as exciting as war, and quite as dangerous. In war you can only be killed once, but in politics many times.

If you're not a liberal at twenty you have no heart, if you're not a conservative at forty you have no brain.

The whole history of the world is summed up in the fact that, when nations are strong, they are not always just, and when they wish to be just, they are no longer strong.

Any 20 year-old who isn't a liberal doesn't have a heart, and any 40 year-old who isn't a conservative doesn't have a brain.

Politics is not a game. It is an earnest business.

It would be a great reform in politics if wisdom could be made to spread as easily and rapidly as folly.
