A liberal education is at the heart of a civil society and at the heart of a liberal education is the act of teaching.

I came at age in the '60s and initially my hopes and dreams were invested in politics and the movements of the time - the anti-war movement the civil rights movement. I worked on Bobby Kennedy's campaign for president as a teenager in California and the night he was killed.

Last year Congress gave the Department of Defense the authority to design a new civilian personnel system for its employees as part of the defense authorization bill.

Our guiding principle was that design is neither an intellectual nor a material affair but simply an integral part of the stuff of life necessary for everyone in a civilized society.

The cult of the individual is killing us. I think Twitter signals the death of western civilisation but people have been saying that since Demosthenes.

We burned to death 100 000 Japanese civilians in Tokyo - men women and children. LeMay recognized that what he was doing would be thought immoral if his side had lost. But what makes it immoral if you lose and not immoral if you win?

Bulls can do nothing to demand justice. They can only defend themselves as best they can in a fight with a pre-determined ending and die never knowing why they were forced to endure such a painful and prolonged death. It's up to us as a civilized society to call for an end to the Running of the Bulls and bullfighting.

A nation or civilization that continues to produce soft-minded men purchases its own spiritual death on the installment plan.

If there hadn't been women we'd still be squatting in a cave eating raw meat because we made civilization in order to impress our girlfriends.

I would say the most help I got was from my dad. My dad is a civil engineer in Switzerland he's 90 years old now so he's no longer active as a civil engineer but still a very active person.
