We must not lose sight of the fundamental issue of policy which is that people who come to the country on visa status must never be abused.

Family traditions are more than arguments with the dead, more than collections of family letters you try to decipher. A tradition is also a channel of memory through which fierce and unrequited longings surge, longings that define and shape a whole life.

Tad Homer-Dixon is a rare kind of public intellectual, who combines real expertise with a commitment to communicate to the widest possible readership. In The Ingenuity Gap he wants us all to wake-up to the fearful possibility that our blithe trust in science and technology may be misplaced.
