When The Going Gets Tough, The Tough

We Are Entering An Increasingly Dangerous Period Of Our History. But I'm An Optimist.

If What We Regard As Real Depends On Our Theory, How Can We Make Reality The Basis Of Our Philosophy? But We Cannot Distinguish What Is Real About The Universe Without A Theory. It Makes No Sense To Ask If It Corresponds To Reality, Because We Do Not Know What Reality Is Independent Of A Theory.

The Boundary Condition Of The Universe Is That It Has No Boundary.

I Do Not Believe In A Personal God.

I Don't Think The Human Race Will Survive The Next Thousand Years, Unless We Spread Into Space. There Are Too Many Accidents That Can Befall Life On A Single Planet. But I'm An Optimist. We Will Reach Out To The Stars.
