It is a great tragedy that science, this wonderful process for finding out what is true, has ceded the spiritual uplift of its central revelations: the vastness of the universe, the immensity of time, the relatedness of all life, and life's preciousness on our tiny planet.

And what greater might do we possess as human beings than our capacity to question and to learn?

The way he treated me & the way I treated him, the way we took care of each other & our family, while he lived. That is so much more important than the idea I will see him someday.

I guess I so desperately want to see us put this planet right. It's so horrifying to me that a fifth of us are starving every night, and that forty thousand children die every single day.

People think that if you are a scientist you have to give up that joy of discovery, that passion, that sense of the great romance of life. I say thats completely opposite of the truth.

If you are searching for sacred knowledge and not just a palliative for your fears, then you will train yourself to be a good skeptic.

Science is nothing more than a neverending search for the truth.
