Conscience is a creator of meaning. As a sense of constraint rooted in our emotional ties to one another, it prevents life from devolving into nothing but a long and essentially boring game of attempted dominance over our fellow human beings, and for every limitation conscience imposes on us, it gives us a moment of connectedness with an other, a bridge to someone or something outside of our often meaningless schemes.

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.

Sociopaths are not inhibited by the notion that it's wrong to be addicted, or wrong to buy illegal drugs. Also, drinking or taking drugs can be a lot of fun, and even if it's not, it can dull that painful boredom for a while. So can certain other things, like taking risks, and particularly if you take a risk-averse person and you can manipulate him or her into taking risks, that's really fun.

The central trait of sociopathy is a complete lack of conscience, which is very difficult for most people to get their heads around, because those of us who do have a conscience can't really imagine what it would be like if we didn't. Most people think that deep down everybody has a conscience, and it turns out that's just not true.

In northwest Alaska, kunlangeta "might be applied to a man who, for example, repeatedly lies and cheats and steals things and does not go hunting, and, when the other men are out of the village, takes sexual advantage of many women." The Inuits tacitly assume that kunlangeta is irremediable. And so, according to Murphy, the traditional Inuit approach to such a man was to insist he go hunting, and then, in the absence of witnesses, push him off the edge of the ice.

People ask me many times, "Aren't you afraid you're going to scare people? Aren't you afraid you're going to make people feel bad about the human race?" I look at it as entirely the opposite. Something you can understand and identify should be less frightening than something you can't. And to understand that there are people who are capable of acting without conscience, without considering other people at all, explains a lot of things.

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.
