The behavior of men to the lower animals, and their behavior to each other, bear a constant relationship.

Well, what is acting but the study of human behavior? And that's so fascinating to me.

Human beings, viewed as behaving systems, are quite simple. The apparent complexity of our behavior over time is largely a reflection of the complexity of the environment in which we find ourselves.

It is with great disappointment that I call on Representative Anthony Weiner to resign. The behavior he has exhibited is indefensible and Representative Weiner's continued service in Congress is untenable.

When you're the victim of the behavior, it's black and white; when you're the perpetrator, there are a million shades of gray.

The biological factors underlying race differences in sports have consequences for educational achievement, crime and sexual behavior.
