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.
Make space in your life for the things that matter, for family and friends, love and generosity, fun and joy. Without this, you will burn out in mid-career and wonder where your life went.
Technology gives us power, but it does not and cannot tell us how to use that power. Thanks to technology, we can instantly communicate across the world, but it still doesn't help us know what to say.
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.
We are biological creatures. We are born, we live, we die. There is no transcendent purpose to existence. At best we are creatures of reason, and by using reason we can cure ourselves of emotional excess. Purged of both hope and fear, we find courage in the face of helplessness, insignificance and uncertainty.
Dreams are where we visit the many lands and landscapes of human possibility and discover the one where we feel at home. The great religious leaders were all dreamers.
Science will explain how but not why. It talks about what is, not what ought to be. Science is descriptive, not prescriptive; it can tell us about causes but it cannot tell us about purposes. Indeed, science disavows purposes.
To defend a country you need an army, but to defend a civilization you need education.
Cyberspace can't compensate for real space. We benefit from chatting to people face to face.
The world we build tomorrow is born in the stories we tell our children today. Politics moves the pieces. Education changes the game.
We need to rediscover the idea of the common good and work together to build a home.
Follow your passion. Nothing - not wealth, success, accolades or fame - is worth spending a lifetime doing things you don't enjoy.
Close to a billion people - one-eighth of the world's population - still live in hunger. Each year 2 million children die through malnutrition. This is happening at a time when doctors in Britain are warning of the spread of obesity. We are eating too much while others starve.
Yom Kippur, the Day of Atonement, is the holy of holies of Jewish time. It is that rarest of phenomena, a Jewish festival without food. Instead it is a day of fasting and prayer, introspection and self-judgment when, collectively and repeatedly, we confess our sins and pray to be written into God's Book of Life.
Religion creates community, community creates altruism and altruism turns us away from self and towards the common good... There is something about the tenor of relationships within a religious community that makes it the best tutorial in citizenship and good neighborliness.
The market economy is very good at wealth creation but not perfect at all about wealth distribution.
No great achiever - even those who made it seem easy - ever succeeded without hard work.
God's forgiveness allows us to be honest with ourselves. We recognize our imperfections, admit our failures, and plead to God for clemency.
Since Hiroshima and the Holocaust, science no longer holds its pristine place as the highest moral authority. Instead, that role is taken by human rights. It follows that any assault on Jewish life - on Jews or Judaism or the Jewish state - must be cast in the language of human rights.
Religion survives because it answers three questions that every reflective person must ask. Who am I? Why am I here? How then shall I live?
