Religious ritual is a way of structuring time so that we, not employers, the market or the media, are in control. Life needs its pauses, its chapter breaks, if the soul is to have space to breathe.

Sometimes the sight of someone in one faith wrestling with that faith can empower you to wrestle with another faith. For me, it was reading about how the Catholic Church wrestled with itself in the 1960s. Pope John XXIII set Nostra Aetate - the Declaration on the Relation of the Church with Non-Christian Religions - in motion. It changed the relationship between Jews and Catholics. Today, Jews and Catholics meet as friends. If you can do that, after the longest history of hatred the world has known, that empowers you as a Jew or a Muslim to wrestle with your faith.

True freedom requires the rule of law and justice, and a judicial system in which the rights of some are not secured by the denial of rights to others.

I believe faith is not certainty but the courage to live with uncertainty.

We need to rediscover the idea of the common good and work together to build a home.

The wisest rule in investment is: when others are selling, buy. When others are buying, sell. Usually, of course, we do the opposite. When everyone else is buying, we assume they know something we don't, so we buy. Then people start selling, panic sets in, and we sell too.

Follow your passion. Nothing - not wealth, success, accolades or fame - is worth spending a lifetime doing things you don't enjoy.
