What makes your heart leap?

Hope lies in dreams, in imagination and in the courage of those who dare to make dreams into reality.

Are we being good ancestors?

I look upon ourselves as partners in all of this, and that each of us contributes and does what he can do best. And so I see not a top rung and a bottom rung - I see all this horizontally - and I see this as part of a matrix. And I see every human being as having a purpose, a destiny, if you like - the destiny that exists in each of us - and find ways and means to provide such opportunities for everyone.

Some people are constructive, if you like. Others are destructive. It's this diversity in humankind that results in some making positive contributions and some negative contributions. It's necessary to have enough to make positive contributions to overcome the problems of each age.

When things get bad enough, then something happens to correct the course. And it's for that reason that I speak about evolution as an error-making and an error-correcting process. And if we can be ever so much better - ever so much slightly better - at error correcting than at error making, then we'll make it.
