At thirteen or fourteen, I was lucky enough to read "The Persistence of Vision" in a science fiction collection published by Orbis at such an affordable price that I could buy every volume with my weekly allowance.

The stories had a powerful impact on me, because at that age concepts like the normalization of sex change or living a full life while being deaf-blind didn't fit into my mental frameworks. I enjoyed it from beginning to end, each and every one of the stories.

Two months ago (almost forty years later) my mother found the old book in our family library, and I've been able to reread it, enjoying it as much or more than the first time. I remembered the general plot of all the stories perfectly, which is proof of their intrinsic quality, and we can clearly see their influence on later authors like my beloved Doctorow.

The most curious thing is that some perspectives have shocked me again. Not the sex change, of course. Not raising children in a commune (whether on Earth or Mars). But sex between adults and minors is a topic that I'm sure makes me more uncomfortable now than when I was a kid.

So, for the second time, I can only be grateful to the author for giving me a good time without condescension or fear of presenting societies different from my own. For making me think. And feel.
