"The brain is biology's greatest challenge. Perhaps in a sense it is the greatest challenge for science as a whole, beyond moon landings, the ultimate particles of the physicist and the depths of astronomical space."

To be motherly is a totally different phenomenon. It is something absolutely human; it transcends animality. It has nothing to do with biology. It is love, pure love, unconditional love. When a mother loves unconditionally - and only a mother can love unconditionally - the child learns the joy of unconditional love. The child becomes capable of loving unconditionally. And to be able to love unconditionally is to be religious. And it is the easiest thing for a woman to do. It is easy for her because naturally she is ready for it.
