It is ridiculous not to escape from one's own vices, which is possible, while trying to escape the vices of others, which is impossible.
Whatever the rational and social faculty finds neither intelligent nor to the common good, it judges, with good reason, beneath itself.
The social nature of humans requires the duty of tolerance and service. At a basic level, the Gods took care to provide for humans by granting them a place to live and sustenance to live. The Gods have endowed humans with the ability to reason and think and act. In this way, they have cared for humans. If the Gods, who are immortal, can provide for humans, why not you too (in your own way)? This is your duty; this is the discipline of action.
You can overcome vices and live a life of virtue (wisdom, justice, courage, temperance).
Anything that is not intelligent or does not support the common good, should be beneath you.
