Let's start with the Army, an unlikely target for the branch of inquiry that Seligman fathered: positive psychology. Instead of mental illness, positive psychology focuses on what makes some of us stronger, happier, and more satisfied than the norm. It involves learning to think differently about both good and bad events and appreciating that there is more than one path to an emotionally satisfying life.
Such touchy-feely stuff would seem out of place among people who wear heavy boots and fatigues.
But there was Seligman at Penn last summer, explaining to a group of sergeants the audaciously ambitious Comprehensive Soldier Fitness program that their generals had just decided to undertake. Ultimately, 1.1 million soldiers will receive training based on positive psychology. The Army hopes it will make them more resilient - less prone to suicide and post-traumatic stress disorder.
Seligman is short and a little paunchy, but not soft. Built more like a butcher than a professor, he paced before the impressively fit soldiers with a rough energy that conveyed both physical vitality and mental restlessness. The product of an unhappy stint in an Albany, N.Y., military school, he easily commanded the room's attention. The sergeants applauded loudly when he said they would teach their fellow soldiers better coping skills.
He talked about blessings, signature strengths, and support for spouses' successes, but his manner was disarmingly rational, backed by charts and studies. His deep, authoritative voice - possibly his best physical attribute - lent his words just the right gravity. He confidently walked the line between grand and grandiose as he pronounced: "We're after creating an indomitable Army."
