Self-education is a continuing source of pleasure to me, for the more I know, the fuller my life is and the better I appreciate my own existence

Modern science fiction is the only form of literature that consistently considers the nature of the changes that face us.

We are all victimized by the natural perversity of inanimate objects...and the assorted human beings who perpetuate and maintain this perversity.

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.
