If you look across a host of measures at adoption studies, fraternal v. identical twin studies, twins-raised-apart studies, the history of early childhood intervention research, naturally-occurring experiments, differences between societies, changes over history, and so forth, you tend to come up with nature and nurture as being about equally important: maybe fifty-fifty. The glass is roughly half-full and half-empty.

The postwar [WWII] GI Bill of Rights - and the enthusiastic response to it on the part of America's veterans - signaled the shift to the knowledge society. Future historians may consider it the most important event of the twentieth century.
We are clearly in the midst of this transformation; indeed, if history is any guide, it will not be completed until 2010 or 2020. But already it has changed the political, economic and moral landscape of the world.
Peter Drucker
Wanted or unwanted, I believe that human life, even at its earliest stages, has certain rights which must be recognized – the right to be born, the right to love, the right to grow old.... When history looks back to this era it should recognize this generation as one which cared about human beings enough to halt the practice of war, to provide a decent living for every family, and to fulfill its responsibility to its children from the very moment of conception.
Ted Kennedy
It is from numberless diverse acts of courage and belief that human history is shaped. Each time a man stands up for an ideal, or acts to improve the lot of others, or strikes out against injustice, he sends forth a tiny ripple of hope, and crossing each other from a million different centers of energy and daring those ripples build a current which can sweep down the mightiest walls of oppression and resistance.
Robert F. Kennedy
When people listen to my music, I hope that they will notice that if you take a piece by a composer like Schubert, the major and the minor triad is an extremely important thing not merely as harmony, but in creating melodic lines. Schubert is always walking up and down with arpeggios on C, E, G and so forth. I am not doing anything different really, except using a different system of harmony.
Elliott Carter
There used to be a thing or a commodity we put great store by. It was called the People. Find out where the People have gone. I don't mean the square-eyed toothpaste-and-hair-dye people or the new-car-or-bust people, or the success-and-coronary people. Maybe they never existed, but if there ever were the People, that's the commodity the Declaration was talking about, and Mr. Lincoln.
John Steinbeck
