Alain de Botton is one of my personal favorite philosophers.
This is possibly one of the most profound videos I've watched on the subject of love and marriage. It truly makes you question yourself and your role in the breakdown of past relationships, and what may lead to the breakdown of present/future relationships. Amazing and profound.
Humans marry wrongly because they don't understand the essence of existence and fail to know who they really are. The probability to marry a wrong person is very high unless you have escaped human tradition. There is a scale of compatibility that defines us as human beings. The majority of people fail to know who they are and how their internal chemistry works. A man is a spirit, living in a body, having a soul and operating with a mind.
“Marry, and you will regret it; don’t marry, you will also regret it; marry or don’t marry, you will regret it either way. Laugh at the world’s foolishness, you will regret it; weep over it, you will regret that too; laugh at the world’s foolishness or weep over it, you will regret both. Believe a woman, you will regret it; believe her not, you will also regret it… Hang yourself, you will regret it; do not hang yourself, and you will regret that too; hang yourself or don’t hang yourself, you’ll regret it either way; whether you hang yourself or do not hang yourself, you will regret both. This, gentlemen, is the essence of all philosophy.” Søren Kierkegaard
