Yes I agree that we all simply believe what we want to believe. I also agree that reason is and ought to be the slave of the passions and that Meaning precedes Truth.
Knowing that, why should I feel ashamed by my choice to see the interconnectedness of everything as divinity? The dignity of humans as divinity? The sense of the transcendent as an intuition? These things suggest themselves. If they be untrue, fine. I always knew I could be wrong. I see no reason to chain myself to meaninglessness for the sake of some more precise truth, because indeed as I have said, Truth capital T is inapprehensible anyway, and I understand that truth only matters in the first place because of meaning and value.
When I first started to work through these issues I was an agnostic materialist who chose for the sake of simple happiness to pursue ethics and egalitarianism as a source of inherent fulfillment. But as I have gone along in attempt to live this belief, I have begun to see that ethics itself is a kind of religion, and that so too is epistemology or investigation, as Thoreau (and many religious/spiritual scientists) all well know.
There is no denying of reality to be done. There is a stark but cheerful embrace of it, as it is, humanity and all.
To claim that this anthropometric view is arrogant is A) wrong since half my worldview (maybe more than half) is mystified by the Universe entire, and B) itself an arrogant claim, because to pretend to know the ultimately significance of human consciousness, agency, and transcendence pretends to a kind of knowledge I expressly do not claim. To know the significance of one thing is only possible by knowing the whole to which the thing is connected in its entirety, which is never something I will pretend to. As I have already indicated - everything must be subjected to doubt.
