Epistemic Sophisms in “Conclusiones Hesbri”

The paper addresses the collection of (broadly speaking) epistemic sophisms discussed in the Heytesburian treatise traditionally referred to as “Probationes conclusionum” and strives to fulfil four tasks based on analyses of its manuscripts: first, to suggest a new, or rather the original title for the text, namely “Conclusiones” (which, in this context, means “Sophisms”); second, to argue in favour of its authenticity by refuting the arguments for the opposite and showing that positive arguments applied to other texts (such as Sophismata asinina) apply to it as well; third, to outline the content of the chapter on epistemic sophisms and compare its topics with those addressed in Regulae solvendi sophismata; and fourth, to present a commented critical edition of two of the sophisms.
