Actually, if you make just one small assumption, then the world becomes perfectly “intelligible”. The bad things that happen to good people become perfectly understandable. The discord that exists within humanity becomes reasonable. And the conflict between doctrines becomes rational. In fact, every nuance of the world becomes intelligible if you make just one small assumption.
Unfortunately, people are afraid to make that assumption. And that assumption is, that solipsism is right. That the world wasn’t created by a benevolent God, it was created by me. The world is the way it is, because the mind can’t imagine anything else. The mind must exist in a world that explains what it is, and where it came from. So the mind creates its own reality, and in so doing it necessarily creates everything else. It creates evil, because it has to. It creates life and death, because it has to. It creates God, because it has to.
And it has to, because it can never ultimately explain where it came from. But in its struggle to explain where it came from, it creates a world that encompasses every possible explanation for where it came from. And it does this because it doesn’t know which one is right. It creates religion, and metaphysics, and science, and evolution, and the big bang. All in an effort to explain the existence of itself. Everything about the world logically follows from the simple realization that I am. And from the overarching need to explain what I am, and where I came from.
Reconciling a benevolent God with an inhumane world is one of the most difficult tasks for a theist. But for a solipsist, the explanation is simple. The world is the way it is because the “I am” is struggling to rationalize “Why I am”.
The world is the way it is, because I am.
