 Lorenzo Valla (Repastinatio, 253) attacked scholastic dialectic, referring to worthiness of belief and belief-worthy things (credibilia) rather than to probability and probabilia. He follows Quintilian’s (the complete text of the Institutio oratoria was rediscovered in the Latin West in 1416) division of belief-worthiness into very firm (firmissimum), strongly disposed (propensius), and not ill-disposed (non  repugnans).[46]  Credibility and truth-likeness are also related to the modal category of possibility. Valla assumes degrees of possibility. Something can be very or slightly possible. Only propositions qualified as very possible were worthy of belief and truth-like (verisimilis). In this context, Valla never once uses the word probabilis. But he approvingly quotes Cicero’s connection of argumentation with probable (probabilis) invention in Book 3 of his Repastinatio dialecticae, where he gets down to dialectic and logic after much previous analysis of language. On the whole, Valla’s probability-related concepts do not seem to differ too starkly from the semantic and proto-frequentist notions of probability (or belief-worthiness) which he shared with the scholastics.
