Today is the first day of Hanukkah, the Festival of Lights. Jews all over the world celebrate the rededication of the second temple in Jerusalem. I want to honour on this day a Jewish composer. I want to honour Jewish scientists and artists and their intellectual output by which they enriched European culture. Among those who brought the light to Europe were the philosophers Baruch de Spinoza and Moses Mendelssohn. The poet Heinrich Heine. The physicist Albert Einstein and the political scientists Hannah Arendt and Eric Voegelin. All five pondered in one way or another the fate of mankind and the experience of God and came to different conclusions. All five deeply cared about humanity, its progress, its well-being and searched for the purpose of life.
