Moreover environmental health at the local level has become narrowly focused very much defined around regulations and the attendant regulatory debates.

If we had in this room a hundred teachers good teachers from good schools and asked them to define the word education there would be very little general agreement.

I think it is totally wrong and terribly harmful if education is defined as acquiring knowledge.

I've never had anyone define purity. You probably can't define purity. Purity is to live according to original design.

While a case can be made for intelligent design I can't figure out why some Christians are so thrilled about that possibility. First of all it doesn't prove there's a God. If anything intelligent design lends support to some form of pantheism that defines God as immanent within nature.

Nothing defines humans better than their willingness to do irrational things in the pursuit of phenomenally unlikely payoffs. This is the principle behind lotteries dating and religion.

A mustache really defines your face. My dad had a mustache when I was growing up and I can still remember when he shaved it he looked like a completely different person.

My definition of courage is never letting anyone define you.

The quality that defines us as Americans is the courage to respond to being hit. The courage to root out and destroy the killers. And most importantly the courage to hold on to our values and protect our hard-won freedoms while doing it.

There's only one requirement of any of us and that is to be courageous. Because courage as you might know defines all other human behavior. And I believe - because I've done a little of this myself - pretending to be courageous is just as good as the real thing.
