I happened upon a news item the other day that reported researchers have found how the medieval church’s prohibition on marriage between relatives promoted, over time, some very positive results for the cultural developments of mankind. Scientists attribute to the ban the reduction of clannish behaviors, broader social cooperation and an individualism that produced free thought and new ideas leading to considerable progress in the development of western societies.
I got to thinking about why exactly the church might have decided to take such a stance in a time well before knowledge of the genetic dangers of inter-breeding were known. Then I happened upon a conjecture by researchers that suggested that disrupting and reducing clan structures created a situation where less inheritors for family properties made it more likely that, sans descendants to pass the farm to, the church would become a likely recipient seeing as how those medieval folks were pretty convinced an extended and fairly unpleasant time in purgatory awaited them and that such time could be shortened through the intercession of the church fathers.
Boy, as much as I might like to think of the church’s intentions as positive there all too often seems to have been ulterior motives.
