“Trust in the Lord with all your heart, and do not lean on your own understanding. In all your ways acknowledge Him, and He shall direct your path.”
Of all the systems devised by humans to deal with ethics and morality, Pragmatism, as a system is IMO, least dependent on emotions and biases, but Pragmatism fails at the point where incomplete, inaccurate human knowledge intersects with partial and faulty understanding of that incomplete and inaccurate knowledge. Other system that are more dependent on preconceptual biases (Pragmatism has some of its own, you know) and that either assume more knowledge than is available or are even more blind to their own misunderstandings are even less appealing that Pragmatism.
Unless one is both omniscient and infinitely wise, the best one can hope for is that one’s own understanding of circumstances and consequences is partial, and one is as likely as not, if one relies only on one’s own knowledge and understanding, to be quite wrong in predicting ultimate outcomes. Short-term outcomes? One might have a better chance, but relying on guidance from Someone who knows juuuuust might be a better idea, hmm?
Oh, for the record, I choose my guidance wrong far more often than I should. *sigh*
