I shall put this in French as well as English because I believe that quotations are best read and spoken in their native language.
French
Le rêve d'égalité et de fraternité universelle ne se réalisera jamais simultanément en chacun. Cependant, convenons, ensemble, de réinventer un monde consacré à la paix, sinon, tout ce que nous ferons sera réduit à néant. - les souvenirs d'Edme Liron
English
The dream of equality and universal brotherhood will never be realised everywhere in all hearts at the same time. But let us agree together to reinvent a world devoted to peace, otherwise everything we do will come to nothing- mémoires d’Edme Liron
"1,500 years ago, everybody knew that the Earth was the center of the universe. 500 years ago, everybody knew that the Earth was flat. And 15 minutes ago, you knew that humans were alone on this planet. Imagine what you'll know tomorrow."
- Agent K, Men in Black
