“In perhaps the most revealing of all the health-related studies, a group of subjects who had contracted malignant melanoma received traditional treatment and then were divided into two groups. One group met weekly for only six weeks; the other did not. Facilitators taught the first group of recovering patients specific communication skills. (When it's your life that's at stake, could anything be more crucial?) After meeting only six times and then dispersing for five years, the subjects who learned how to express themselves effectively had a higher survival rate--only 9 percent succumbed as opposed to almost 30 percent in the untrained group.”

“People who read me seem to be divided into four groups: twenty-five percent like me for the right reasons; twenty-five percent like me for the wrong reasons; twenty-five percent hate me for the wrong reasons; twenty-five percent hate me for the right reasons. It's that last twenty-five percent that worries me.”

“When I was in school I studied biology. I learned that in making their experiments scientists will take some group--bacteria, mice, people--and subject that group to certain conditions. They compare the results with a second group which has not been disturbed. This second group is called the control group. It is the control group which enables the scientist gauge the effect of his experiment. To judge the significance of what has occurred. In history there are no control groups. There is no one to tell us what might have been. We weep over the might have been, but there is no might have been. There never was. It is supposed to be true that those who o not know history are condemned to repeat it. I don't believe knowing can save us. What is constant in history is greed and foolishness and a love of blood and this is a thing that even God--who knows all that can be known--seems powerless to change.”

“A tribe is a group of people connected to one another, connected to a leader, and connected to an idea. For millions of years, human beings have been part of one tribe or another. A group needs only two things to be a tribe: a shared interest and a way to communicate.”

“The average human being is actually quite bad at predicting what he or she should do in order to be happier, and this inability to predict keeps people from, well, being happier. In fact, psychologist Daniel Gilbert has made a career out of demonstrating that human beings are downright awful at predicting their own likes and dislikes. For example, most research subjects strongly believe that another $30,000 a year in income would make them much happier. And they feel equally strongly that adding a 30-minute walk to their daily routine would be of trivial import. And yet Dr. Gilbert’s research suggests that the added income is far less likely to produce an increase in happiness than the addition of a regular walk.”

“People who are skilled at dialogue do their best to make it safe for everyone to add their meaning to the shared pool--even ideas that at first glance appear controversial, wrong, or at odds with their own beliefs. Now, obviously they don't agree with every idea; they simply do their best to ensure that all ideas find their way into the open.”

“No one could leave the group by his or her own volition and put the group at risk of having its secrets revealed.”
