I like the vibes.

But worse, the path is not merely narrow, but winding, with frequent dead ends requiring frequent backtracking. If ever you think you're closer to the truth - discard that hubris, for it may inhibit you from leaving a dead end, and there your search for truth will end. That is the path of the crank.

I don't like this part. First, thinking that you're closER to the truth is not really a problem, it's thinking you've arrived at the truth that arguably is. Second, I think sometimes human beings can indeed find the truth. Underconfidence is just as much a sin as overconfidence, but referring to hubris in the way that you did seems like it would encourage false humility. I think you should say something more like "for every hundred ides professed to be indisputable truths, ninety nine are false", and maybe add something about how there's almost never good justification to refuse to even listen to other people's points of view.

The path of rationality is a path without destination.

I don't agree with this either, or most of the paragraph before it: there are strong trends.
