Isaac Asimov's death on April 6, 1992, was a great loss to literature, science, and freethought. The vision of one of America's most prolific authors is unmatched today, and his pointed honesty shines through in this fascinating collection of essays, now reissued in this special tribute edition. Asimov demonstrates his extraordinary skill at disseminating knowledge from across the spectrum of scientific disciplines as his "roving mind" ranges from the polemical to the persuasive, from the speculative to the realistic. The sixty-two essays in this volume include such subjects as creationism, the distinction between real science and pseudoscience, censorship, the population explosion, technophobia, the social consequences of technological progress, cloning, the possibility of contacting extraterrestrial life, and the wonders of the cosmos. There are also thoughts on his style of writing, stories about his personal life, and recollections of family history - all written in the clear and elegant prose for which Asimov was noted.
