Conservatism, for me, is the philosophy and the politics of attachment.

A high culture is the self-consciousness of a society. It contains the works of art, literature, scholarship and philosophy that establish a shared frame of reference among educated people.

The great benefit of philosophy, which is also its great weakness, is that all its steps are taken in the spirit of doubt.

Politics is a matter of day-to-day improvisation, and it often seems as though the major parties are guided only by the desire to stay in office and not by any philosophy that might justify their doing so.

My undergraduate years at the University of Nebraska were a special time in my life: the combination of partying and intellectual awakening that is what the undergraduate years are supposed to be. I went to the university with the goal of becoming an engineer; I had no concept that one could pursue science as a career.

I look back upon graduate school as being a very happy period in my life. The chance to be thoroughly immersed in physics and to be surrounded by friends pursuing similar goals was a marvelous experience.

My older brother was the person who got me interested in science in general. He used to tell me what he learned in school. My first memory of mathematics is probably the time that he told me about the problem of adding numbers from 1 to 100.

I work in string theory. This is a branch of physics which assumes that the elementary objects in the universe are not particles but one-dimensional objects, that is, strings.
