We... heal ourselves by giving others what we most need.

I apologize to all of my colleagues who've been writing up storms, but as a culture we've essentially put ourselves into a position where Mark Zuckerberg can say, "Privacy as a social norm is no longer relevant," and a lot of people don't blink an eye.

Teenagers would rather text than talk. They feel calls would reveal too much.

If behind popular fascination with Freudian theory there was a nervous, often guilty preoccupation with the self as sexual, behind increasing interest in computational interpretations of mind is an equally nervous preoccupation with the self as machine.

If you're happy with where the Internet, Facebook, and Twitter have taken you, I'm not the Grinch. Someone called me Sherry Turkle's "evil Luddite twin." I'm not that. I enjoy the bounties of this technology. But if you fear that your connected life is running away with you, read the book, reflect, talk to your family and friends. I think we deserve better than some of the places that we've gotten with this technology.

One thing is certain: the riddle of mind, long a topic for philosophers, has taken on new urgency. Under pressure from the computer, the question of mind in relation to machine is becoming a central cultural preoccupation. It is becoming for us what sex was to the Victorians--threat and obsession, taboo and fascination.

The computer takes up where psychoanalysis left off. It takes the ideas of a decentered self and makes it more concrete by modeling mind as a multiprocessing machine.
