“I looked at something that I had seen going on with the world, which is that I thought there were too many unjust acts. And I wanted there to be more just acts, and fewer unjust acts.
And one can ask, “What are your philosophical axioms for this?” And I say, “I do not need to consider them. This is simply my temperament. And it is an axiom because it is that way.” That avoids getting into further unhelpful philosophical discussion about why I want to do something. It is enough that I do.
In considering how unjust acts are caused, and what tends to promote them, and what promotes just acts, I saw that human beings are basically invariant. That is, their inclinations and biological temperament haven’t changed much over thousands of years. Therefore the only playing field left is: what do they have and what do they know?”
