The line between good and evil is movable and it's permeable.

I was discriminated against because I was Jewish, Italian, black and Puerto Rican. But maybe the worst prejudice I experienced was against the poor. I grew up on welfare and often had to move in the middle of the night because we couldn't pay the rent.

The level of shyness has gone up dramatically in the last decade. I think shyness is an index of social pathology rather than a pathology of the individual.

What troubles me is the Internet and the electronic technology revolution. Shyness is fueled in part by so many people spending huge amounts of time alone, isolated on e-mail, in chat rooms, which reduces their face-to-face contact with other people.

We want to believe in the essential, unchanging goodness of people, in their power to resist external pressures, in their rational appraisal and then rejection of situational temptations. We invest human nature with God-like qualities, with moral and rational faculties that make us both just and wise. We simplify the complexity of human experience by erecting a seemingly impermeable boundary between Good and Evil.

Time perspective is one of the most powerful influences on all of human behavior. We're trying to show how people become biased to being exclusively past-, present- or future-oriented.

I started studying shyness in adults in 1972. Shyness operates at so many different levels. Out of that research came the Stanford shyness clinic in 1977.
