Millennium by John Varley quotation?

[markrox21]

I'm doing a research paper and in it I would like to put the quote:"Time travel is so dangerous it makes H-bombs seem like perfectly safe gifts for children and imbeciles. I mean, what's the worst that can happen with a nuclear weapon? A few million people die: trivial. With time travel we can destroy the whole Universe, or so the theory goes"from Millennium by John Varley (1983), however I can't seem to find what page it was on anymore. That the page number is needed for the citation so if anyone happens to have it, would you please let me know (or an internet source of where I might be able to find it).Thanks.
