On my recent trip to Israel, I had the opportunity to visit Yad Vashem, Israel's national Holocaust memorial, and reaffirm our collective responsibility to confront anti-Semitism, prejudice, and intolerance across the world. On this Yom Hashoah, we must accept the full responsibility of remembrance, as nations and as individuals-not simply to pledge "never again," but to commit ourselves to the understanding, empathy and compassion that is the foundation of peace and human dignity.

Everything is only for a day, both that which remembers and that which is remembered. Observe constantly that all things take place by change, and accustom thyself to consider that the nature of the Universe loves nothing so much as to change the things which are and to make new things like them. For everything that exists is in a manner the seed of that which will be.

Laws should be made to serve the people. People should not be made to serve the laws.

The universe and the observer exist as a pair. I cannot imagine a consistent theory of the universe that ignores consciousness.

The most curious social convention of the great age in which we live is the one to the effect that religious opinions should be respected.

Distance does not decide who is your brother and who is not. The church is going to have to become the conscience of the free market if it's to have any meaning in this world - and stop being its apologist.
