Cultures of honor tend to take root in highlands and other marginally fertile areas, such as Sicily or the mountainous Basque regions of Spain. If you live on some rocky mountainside, the explanation goes, you can't farm. You probably raise goats or sheep, and the kind of culture that grows up around being a herdsman is very different from the culture that grows up around growing crops. The survival of a farmer depends on the cooperation of others in the community. But a herdsman is off by himself. Farmers also don't have to worry that their livelihood will be stolen in the night, because crops can't easily be stolen unless, of course, a thief wants to go to the trouble of harvesting an entire field on his own. But a herdsman does have to worry. He's under constant threat of ruin through the loss of his animals. So he has to be aggressive: he has to make it clear, through his words and deeds, that he is not weak.
