I will never apologize for saying that the future of humanity and the future of the world is going to be defined by what we have in common as opposed to those things that separate us and ultimately lead us into conflict.
O Voltaire! O humanity! O idiocy! There is something ticklish in "the truth," and in the SEARCH for the truth; and if man goes about it too humanely-"il ne cherche le vrai que pour faire le bien"-I wager he finds nothing!
You do not know the unfathomable cowardice of humanity...servile in the face of force, pitiless in the face of weakness, implacable before blunders, indulgent before crimes...and patient to the point of martyrdom before all the violences of bold despotism.
What is the use of living, if it be not to strive for noble causes and to make this muddled world a better place for those who will live in it after we are gone? How else can we put ourselves in harmonious relation with the great verities and consolations of the infinite and the eternal? And I avow my faith that we are marching towards better days. Humanity will not be cast down. We are going on swinging bravely forward along the grand high road and already behind the distant mountains is the promise of the sun.
[O]nly if every individual strives for truth can humanity attain a happier future; the atavisms in each of us that stand in the way of a friendlier destiny can only thus be rendered ineffective.
