Every young person needs some adult who's just wild and crazy about them!

My high school, like most high schools, had a pretty rigid stratification system. Kids were clustered into groups - the studious ones, the athletes, the popular ones - and we never crossed paths with each other. You stayed in your air-tight group, and you were suspicious of people in other groups.

At its deepest level, I think teaching is about bringing people into communion with each other, with yourself as the teacher, and with the subject you are teaching.

Every good teacher and every good parent has somehow learned to negotiate the paradox of freedom and discipline. We want our children and our students to become people who think and live freely, yet at the same time we know that helping them become free requires us to restrict their freedom in certain situations.

Science requires an engagement with the world, a live encounter between the knower and the known.

We are here not only to transform the world but also to be transformed.

There's a lot of fear connected with the inner journey because it penetrates our illusions. Taking the inner journey will lead you into some very shadowy places. You're going to learn things about yourself that you'll wish you didn't know. There are monsters in there-monsters you can't control-but trying to keep them hidden will only give them greater power.
