If courage is acting according to one's conscience despite pain or fear, then strength is the ability to keep conscience awake and in force despite the demands of authorities to do otherwise.

In Western culture, particularly North America, a lot of rules are descriptors for sociopathy: a general acceptance of lying as long as you win, an attitude of "me first," an attitude that what it looks like is more important than what it is. This makes it much easier for a sociopath to be camouflaged in our culture.

If you don't have a conscience, what is your behavior like? Apparently, if you don't have a conscience, if you don't really . . . love, then the only thing that's left for you is the game - it's about controlling things.

If you have reached the point where you're certain that person has no conscience, or is in it to win rather than to love you, then the very best thing you can do is to get away. That's a very hard lesson to learn, and, furthermore, it's not always possible.

Sociopaths are often extremely charming. They are people who are better than you and me at charming people, at being charismatic. I've heard this more often than I can count: "He was the most charming man I ever met," or, "She was the sexiest woman I ever met," or, "The most interesting person I ever met . . ."

Conscience is the still small voice that has been trying since the infancy of our species to tell us that we are evolutionarily, emotionally, and spiritually One, and that if we seek peace and happiness, we must behave that way.

The physical basis for sociopathy is approximately 50 percent inheritable, which sounds more dramatic than it probably is, because most personality characteristics that psychologists test for and study the genetics of are about 50 percent inheritable. Introversion, extroversion, it turns out that they're about 50 percent inheritable, which means that somehow sociopathy is physical, it's organic.
