I think the demarcation between truth(decidability) and choice (preference) is complete.

Philosophy now only tells us choice, while law (reciprocity), science(consistency correspondence, and coherence), and mathematics(measurement) provide decidability regardless of choice.

The top of the epistemic pyramid is not philosophy(rationalism) but testimony, law, science, mathematics, and the logic faculty in a consistent coherent ontology. While philosophy (arbitrary ontology) has nothing to say but choice.

In other words, Law (cooperation) science (evidence), mathematics(measurement) are merely an extension of testimony. Which is why the west developed them. We are the only people that base our law entirely on sovereignty and therefore we have no other choice but testimony, law, science and math for decidability.
