Antoine De Saint-Exupéry said this quote

He is among those beings of great scope who spread their leafy branches willingly over broad horizons. To be a man is, precisely, to be responsible. It is to know shame at the sight of poverty which is not of our making. It is to be proud of a victory won by our comrades. It is to feel, as we place our stone, that we are contributing to the building of the world.
