Ah, makes sense. I have a post on the explain quadras thread inspired by this response. Te-valuers, especially deltas, seek conceptual stability. Fe valuers, betas above all, are much more willing to accept conceptual instability for the sake of questing towards some ideal. Deltas assume that there is a "fact" that can be "established," and want to move on from there. Betas are more inclined to note that "facts" are indeed "established," that is, conventions that we agreed to assume, which may or may not reflect nature, or what is. I think there's a quote from Nietzche wherein he says something to the effect that truths are lies that people have forgotten are lies. Deltas take those truths as truths. Beta, in the quest for the (unattainable) ideal, are more willing to be in flux, not not hold so tightly to those truths which are necessary to Te types (and to betas to some degree, although again, preference is key; I wish that I were strong enough to live without "facts," while deltas would find such a notion ludicrous).
Again, I am reminded that strong or valued Ni often leads to Keats' Negative Capability ("being in Mysteries, uncertainties, without any irritable reaching after facts"), which is, at its core, an ability to deal with the absence of facts, while weak or unvalued Ni often leads to a lack thereof.
