It is the chief characteristic of the religion of science that it works.

Although we will hate and fight the machines, we will be supplanted anyway, and rightly so, for the intelligent machines to which we will give birth may, better than we, carry on the striving toward the goal of understanding and using the Universe, climbing to heights we ourselves could never aspire to.

Humanity has the stars in its future, and that future is too important to be lost under the burden of juvenile folly and ignorant superstition.

However much the creationist leaders might hammer away at their scientific and philosophical points, they would be helpless and a laughing-stock if that were all they had. It is religion that recruits their squadrons. Tens of millions of Americans, who neither know nor understand the actual arguments for - of even against - evolution, march in the army of the night, their Bibles held high.

Society is much more easily soothed than one's own conscience.

When I die I won't go to heaven or hell; there will just be nothingness.
