If I’m acting on the assumption that there is no God’s-eye-view of things, no Objective perspective which we can touch or be influenced by then I am left with my view and you with yours. I don’t have to claim that the no-Objective-View belief is the absolute truth, I can just ask those who contend otherwise – that there is an Objectively correct view - why they believe it and examine it. So assuming no way in which things are which acts as the final arbiter for whose right, we are left with the best understanding that we make, alone and together. And when we find there are conflicts in our views we can agree to disagree, compromise, discuss it, or fight.
So why do I like the no-Objective-View view? Because I wanted to use reason rigorously and find the right view, but found that the arguments against that being possible were powerful. Rorty, Derrida, Wittgenstein, Buddhism and others all agreed that that kind of certainty couldn’t be found using reason. Yet my psyche still contained the desire to find it: the great quest for Truth. I could continue the quest, perhaps trying to find some experiential certainty through spiritual practices or try to alter the desire and treat it as misguided. But what are the psychological reasons for adopting this relativistic view. I said earlier that people choose their beliefs for psychological reasons, yet here I explain why I chose an important belief by saying that reason led me to it. To be consistent I should explain why that no-Objective-View view is attractive to me. A psychological account of why I attach to this view is needed to be consistent with my argument that we fundamentally believe for personal psychological reasons
