Ours has been called a culture of narcissism. The label is apt but can be misleading. It reads colloquially as selfishness and self-absorption. But these images do not capture the anxiety behind our search for mirrors. We are insecure in our understanding of ourselves, and this insecurity breeds a new preoccupation with the question of who we are. We search for ways to see ourselves. The computer is a new mirror, the first psychological machine. Beyond its nature as an analytical engine lies its second nature as an evocative object.

Not every advance is progress. Not every new thing is better for us humanly.

These days, when people are alone, or feel a moment of boredom, they tend to reach for a device. In a movie theater, at a stop sign, at the checkout line at a supermarket and, yes, at a memorial service, reaching for a device becomes so natural that we start to forget that there is a reason, a good reason, to sit still with our thoughts: It does honor to what we are thinking about. It does honor to ourselves.

People are lonely. The network is seductive. But if we are always on, we may deny ourselves the rewards of solitude.

We all really need to listen to each other, including to the boring bits.

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.
