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.

I speak about universal evolution and teleological evolution, because I think the process of evolution reflects the wisdom of nature. I see the need for wisdom to become operative. We need to try to put all of these things together in what I call an evolutionary philosophy of our time.
