Some set theories give up Separation in exchange for a universal set [Rayo/Uzquiano]

Three stages of philosophical logic: syntactic (1905-55), possible worlds (1963-85), widening (1990-) [Horsten/Pettigrew]

Logical formalization makes concepts precise, and also shows their interrelation [Horsten/Pettigrew]

Absolute generality is impossible, if there are indefinitely extensible concepts like sets and ordinals [Rayo/Uzquiano]

Perhaps second-order quantifications cover concepts of objects, rather than plain objects [Rayo/Uzquiano]

Models are sets with functions and relations, and truth built up from the components [Horsten/Pettigrew]

Epistemic logic introduced impossible worlds [Horsten/Pettigrew]
10. Modality / E. Possible worlds / 1. Possible Worlds / e. Against possible worlds
Possible worlds models contain sets of possible worlds; this is a large metaphysical commitment [Horsten/Pettigrew]
Using possible worlds for knowledge and morality may be a step too far [Horsten/Pettigrew]
11. Knowledge Aims / A. Knowledge / 4. Belief / a. Beliefs
Involuntary beliefs can still be evaluated [Feldman/Conee]
13. Knowledge Criteria / B. Internal Justification / 3. Evidentialism / b. Evidentialism
Evidentialism is the view that justification is determined by the quality of the evidence [Feldman/Conee]
Beliefs should fit evidence, and if you ought to believe it, then you are justified [Feldman/Conee]
13. Knowledge Criteria / C. External Justification / 3. Reliabilism / a. Reliable knowledge
If someone rejects good criticism through arrogance, that is irrelevant to whether they have knowledge [Feldman/Conee]

The domain of an assertion is restricted by context, either semantically or pragmatically [Rayo/Uzquiano]
