“An optimist is a person who sees a green light everywhere, while a pessimist sees only the red stoplight... the truly wise person is colorblind.”

Albert Schweitzer, OM was a French-German theologian, organist, philosopher, and physician. He was born in the German province of Alsace-Lorraine and although that region had been reintegrated into the German Empire four years earlier, and remained a German province until 1918, he considered himself French and wrote mostly in French. His mother-tongue was Alsatian German.
