There is an objective truth to reality. That truth isn't self-evident: [[There is no such thing as explanationless theories]]. Theories about reality must be conjectured: [[Theories are conjectured]]. These explanations, even our best ones, are fallible: [[People (and the explanations they make) are fallible]]. But just because our knowledge about objective reality are fallible doesn't mean they're subjective or arbitrary. Our knowledge about objective reality exists outside of a subjective perspective where it can be critiqued and used by many people. And this knowledge is useful, so it can't be arbitrary: [[Good explanations solve problems]].
