Dharmakīrti(as the originator of the doctrine being discussed): An influential Indian Buddhist philosopher from the 7th century CE who developed important theories about how we know things and how the mind works.
Erroneous grasping(describes a fundamental mistake in how we perceive reality): Misunderstanding or incorrectly perceiving how things actually exist; in Buddhist thought, this usually means falsely believing things are solid, permanent, or independent when they're not.
Two-truths doctrine(an example of Buddhist ideas about reality): A Buddhist teaching that reality can be understood in two different ways: the everyday way we normally see things, and a deeper way that reveals how everything is interconnected and doesn't have independent existence.
anti-realism(Medieval philosophy of universals/relations): A minority position in the Latin West, possibly having a foothold in the Arabic-speaking world; its more radical forms were always marginal. Associated with views reportedly held by figures like Auriol, and possibly Gilbert of Poitiers before retraction.
