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

We may be living at that moment, on the cusp, when we go from being a species that feels a kind of loneliness in the cosmos to actually one sometime in the not too distant future being able to confirm the existence of other intelligent life.

For most of the history of our species we were helpless to understand how nature works. We took every storm, drought, illness and comet personally. We created myths and spirits in an attempt to explain the patterns of nature.

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.

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.

We batter this planet as if we had someplace else to go.
