XX knows of

Rules for ‘XX knows PP

X: Person, P: Prop, p: P \vdash X knows P(p): Prop

X judges P, P is true, the judgement is reliable.

Do we need X\vdash_X? XP\vdash_X P is true to X\vdash X believes P?

Ways of forming judgement, perception, testimony, reason,…

What of ‘XX doesn’t know PP’? Could be he thinks he knows it? Or doesn’t yet know it. Would require different justifications.
