It is one of my favourite books, but I can probably explain what I'm getting at.

The idea is that... what we call "selfishness", ie greed, gluttony, crime, etc...

These are not actually ultimately in ones own interest. These are the true 'selfless' acts. Self is, in fact, a very positive quality. Acting in accordance with your own wants and needs is, in fact, the harmony of nature. The Grace of God.

Rand says 'There are no conflicts of interests among rational men.'

This is too close to the concept of satanism for some people. indeed, Rand considers herself atheist. I actually think hers is the only moral atheist position.

I have another favourite teacher whose perspective can further clarify the idea. He relates the idea of "Integrity" with this. He defines integrity as the recognition of your own integration with the rest of creation. and so by harming another, you also harm yourself, and by helping yourself, you also help others. integrity is knowing this.

Anyways, I thought these ideas might give you some faith in humanity's ability to live peacefully. Remember that there is a multi-trillion dollar effort to keep humanity confused and divided. that effort will disappear with the deep state, and then you will begin to see humanity's real potential.
