Just like Karl Marx, another German sociologist Max Weber also observed alienation of urban worker. However, his life appears to be a prime example of marriage of enchantment and capitalism.
His personal life had taken natural recourse on love and lust. As I have mentioned before love is asexual and only related to motivation. He had a love relationship with his wife Marianne Weber which was asexual. However, he also had lust relationship with two women. Now, the only transgression or irrationality appears to be having lust relationship with more than one woman. But that probably indicates his misunderstanding of love and lust.
Had he understood scientific nature of these feelings (which he thought irrational) he would have handled his personal life more methodically. In his case, over rationalization of marriage led enchanted escapism with a third woman(or second in lust scale). In the end though he had a very scientific relationship with his love (asexual), his lust lost the point as it didn't produce any offspring too.
