Eighteen SF stories, mostly written in the 70's to 1983, the publish date. Toime-proven authors some of whose novels you might have read: Ursula LeGuin, Gene Wolfe, Clifford D. Simak, Algis Budrys, R. A. Lafffert. All entertaining.
Excerpts from the introduction:
"Evolution tells us we have changed from quite other beings into what we are now. Therefore (should we survive--touch wood) we ought to change from what we are today into quite other future beings."
"And it may be that we may not change our bodies at all, but deeper down in our beings. . ."
"It's interesting, then, that when a range of writers are invited to concentrate upon the theme of change...many should chose to describe not only bodily alterations, but inner changes as well."
