Your opinions under shifting borders of certainty

An opinion has at least to be probable
 in order to be more probable than another opinion. 

Probability-related terminology played an important role in medieval and Renaissance philosophy. Terms such as ‘probable’ (probabilis), ‘credible’ (credibilis) or ‘truth-like’ (verisimilis) were used to assess philosophical claims, qualify uncertain conclusions, gauge the force of arguments and temper academic disagreement. 

Beyond that, they had a significant impact on the regulation of legal proceedings, moral action and everyday life. The probability-related terminology of the Middle Ages descended from ancient sources such as Aristotle, Cicero and Boethius

This background is important for charting the shifting borders of certainty and uncertainty, or knowledge and opinion, in European philosophy

 For their vocabulary, medieval and Renaissance authors could draw on a well-stocked ancient Greek and Roman store of probability-related terms. in consequence, a variety of Latin terms were in use, which are today translated as ‘probable’, ‘plausible’, ‘reputable’ (probabilis); ‘truth-like’, ‘apparently true’ (verisimilis); ‘credible’, ‘worthy of belief’ (credibilis, opinabilis); 

Contrast today say in the current febrile political landscape of the USA where certainty claims from indubitable premises appears to be the norm. Perhaps these certainty opinion makers should start tilling the conceptual field of probability, 

For instance the claim, ;I am right' a supposedly objective claim, 
 dependes on the actual existence of the supporting basis.

Morality does not inhere in as does the sting in the bee

Facts of nature determine the degree to which predicates inhere in a subject, so that it becomes objectively probable that a mother loves her child.
