Our duty is to be useful, not according to our desires but according to our powers.
Henri Frederic Amiel

Our technological powers increase, but the side effects and potential hazards also escalate.
Alvin Toffler

It's a great mistake, I think, to put children off with falsehoods and nonsense, when their growing powers of observation and discrimination excite in them a desire to know about things.
Anne Sullivan

We are the only class in history that has been left to fight its battles alone, unaided by the ruling powers. White labor and the freed black men had their champions, but where are ours?

Muhammad Ali Jinnah

Today, the Muslim world is the poorest of the global powers.
Mahmoud Ahmadinejad

Phillips Brooks

To say, 'well done' to any bit of good work is to take hold of the powers which have made the effort and strengthen them beyond our knowledge.
Phillips Brooks

In the wars of the European powers in matters relating to themselves we have never taken any part, not does it comport with our policy so to do. It is only when our rights are invaded or seriously menaced that we resent injuries or make preparation for our defence.
James Monroe

I have great satisfaction in stating that our relations with France, Russia, and other powers continue on the most friendly basis.
James Monroe
