Sci-fi uses the images that sf - starting with H.G. Wells - made familiar: space travel, aliens, galactic wars and federations, time machines, et cetera, taking them literally, not caring if they are possible or even plausible. It has no interest in or relation to real science or technology. It's fantasy in space suits. Spectacle. Wizards with lasers. Kids with ray guns. I've written both, but I have to say I respect science fiction enough that I wince when people call it sci-fi.

Ursula K. Le Guin... the habit of literature [is] the best defense against believing the half-truths of ideologues and the lies of demagogues.
Ursula K. Le GuinLife rises out of death, death rises out of life; in being opposite they yearn to each other, they give birth to each other and are forever reborn. And with them, all is reborn, the flower of the apple tree, the light of the stars. In life is death. In death is rebirth. What then is life without death? Life unchanging, everlasting, eternal?-What is it but death-death without rebirth?
