When someone begins on that arrangement called marriage, he is getting into something which is, to say the least, adventurous. When a couple get married, they are doing something they know nothing about. And, from all indications, when they have tried it more than once, they know no more about it the second time than they did the first.
Marriage is the foundation of the family unit.
It is necessary economically and otherwise to the society the way it is set up in present time. A culture will go by the boards if its basic building block, the family, is removed as a valid building block. So one can be fairly sure that he who destroys marriage destroys the civilization. The marriage relationship, basically, is a postulated relationship. A postulate is a conclusion, decision or resolution about something.
