I’m looking for the sutta (?in the Atthakavagga) “where the Buddha also describes how the sage, or the wise person, might behave. … He lets go of one position without taking another. He is not defined by what he knows, nor does he join a dissenting faction. He assumes no view at all.”
Not exactly what you are looking for but pretty nice anyway
I know and see the scope of convictions, the scope of grounds for views, fixation on views, obsession with views, the origin of views, and the uprooting of views.
Yāvatā, āvuso, diṭṭhi yāvatā diṭṭhiṭṭhānaṃ diṭṭhiadhiṭṭhānaṃ diṭṭhipariyuṭṭhānaṃ diṭṭhisamuṭṭhānaṃ diṭṭhisamugghāto, tamahaṃ jānāmi tamahaṃ passāmi.
Knowing and seeing thus, why should I say:
Tamahaṃ jānanto tamahaṃ passanto kyāhaṃ vakkhāmi:
‘I neither know nor see?
’‘na jānāmi na passāmī’ti?
