Very little in science fiction can transcend the gimmickry of a technical conceit, yet without that conceit at its heart a book is not truly science fiction. Furthermore, so little emerging thought and technology is employed by sf writers today that the genre is lagging far behind reality both in the cosmology area and the technology area: sf is no longer a place to experiment, but is now very derivative.

You're not one to take lightly, to love of for an evening and leave of a dawn.

There must be love, and understanding, to betray. Most men haven't the wit or the honor for betrayal: not to know it when they see it; not the stomach to apprehend it as they do it. Most men, blind and dumb in their self-centeredness, don't betray: they merely disappoint.

Fight for life itself and everlasting freedom of the human spirit.

Wanting neither too much to live, nor too much to die.

‎Old enough to kill means old enough to die

The only unfair fight is the one you lose.
