This whole thread is basically an equivocation of the term "disinterested". I absolutely acknowledge the fact that knowledge, and the pursuit of knowledge (or truth, let's say), is always finite and situated within some given medium. But this thread seems to be taking "disinterested" to mean "absolutely without motivation", and taking "motivation" to mean "one's entirely subjective reason". There is of course a good sense in which we should be on guard against this kind of stuff, but I don't think it's at all as widespread in philosophy as this thread is making it out to be. It seems to me obvious enough that we must have our own commitments to what things like "truth", "knowledge", etc. mean in order for us to be able to pursue them, but I'm getting the impression that what this thread is devolving into is a discussion about how those interested in these kinds of pursuits are really just rationalizing their beliefs instead of presenting reasoned views that respond to other views in a critical way (and of course it's devolving into other things as well, good ol' r/philosophy for ya!).
