I probably skipped up to half the stories. This book is quite a mixed bag - some great stories that I remember decades after I first read them, and some really uninteresting stories that I couldn't even get started.
Back in the 60s, SF posed some challenging questions, some of which are covered in this book, particularly relating to sexuality and a utopia.
The stories that stood out, were:-
"A Toy for Juliette" by Robert Bloch
"The Prowler in the City at the Edge of the World" by Harlan Ellison
"The Night That All Time Broke Out" by Brian W. Aldiss
"Faith of Our Fathers" by Philip K. Dick
"The Recognition" by J. G. Ballard
"Judas" by John Brunner

These two were memorable for being controversial:-
"Sex and/or Mr. Morrison" by Carol Emshwiller
"If All Men Were Brothers, Would You Let One Marry Your Sister?" by Theodore Sturgeon
