The correct perspective would not have any blind spots, would it?
Except towards the unanswerable question; does this perspective have any blind spots?
When you're unaware of a blind spot, you won't realize it's there. Steve's very new-agey philosophy is to shift between beliefs so that he get's a notion of where his blind spots lie and what beliefs he can adopt to prevent this from happening.
But even with this kind of philosophy you never reach the point where you can say with all confidence that you have located and solved all your blind spots. There may still be another one out there, perhaps a catastrophically huge one that you're completely unaware of.
It's the process of growth that's the important element of this exploration; not reaching any fixed state.
