Si bien es posible que la psicología haya desatendido la virtud, no cabe duda de que la religión y la filosofía no lo han hecho y existe una converge… - Martin E P Seligman

Good science requires the interplay of analysis and synthesis. One never knows if basic research is truly basic until one knows what it is basic to. Modern physics came into its own not because of its theories — which can be enormously counterintuitive and highly controversial (muons, wavicles, superstrings, the anthropic principle, and all that) — but because physicists built the atomic bomb and modern nuclear power plants.

You go into flow when your highest strengths are deployed to meet the highest challenges that come your way. In well-being theory, these twenty-four strengths underpin all five elements, not just engagement: deploying your highest strengths leads to more positive emotion, to more meaning, to more accomplishment, and to better relationships.

The closer someone lived to someone who was lonely, the lonelier the second individual felt. The same was true for depression, but the blockbuster was about happiness. Happiness was even more contagious than loneliness or depression, and it worked across time. If person A’s happiness went up at time 1, person B’s — living next door — went up at time 2. And so did person C’s, two doors away, by somewhat less. Even person D, three doors away, enjoyed more happiness. This has significant implications for morale among groups of soldiers and for leadership. On the negative side, it suggests that a few sad or lonely or angry apples can spoil the morale of the entire unit. Commanders have known this forever. But the news is that positive morale is even more powerful and can boost the well-being and the performance of the entire unit. This makes the cultivation of happiness — a badly neglected side of leadership — important, perhaps crucial.
