How was I able to live alone before, my little everything? Without you I lack self-confidence, passion for work, and enjoyment of life--in short, without you, my life is no life. [Written to his wife, Mileva]

I never thought that others would take my theories so much more seriously than I did.

With all my heart I believe that the world's present system of sovereign nations can only lead to barbarism, war and inhumanity, and that only world law can assure progress towards a civilized peaceful community.

I no longer believed in the known God of the Bible, but rather in the mysterious God expressed in nature.

I consider it important, indeed urgently necessary, for intellectual workers to get together, both to protect their own economic status and, also, generally speaking, to secure their influence in the political field.

For the most part we humans live with the false impression of security and a feeling of being at home in a seemingly familiar and trustworthily physical and human environment. But when the expected course of everyday life is interrupted, we realize that we are like shipwrecked people trying to keep their balance on a miserable plank in the open sea, having forgotten where they came from and not knowing whether they are drifting. But once we fully accept this, life becomes easier and there is no longer any disappointment.
