13. Knowledge Criteria / A. Justification Problems / 2. Justification Challenges / a. Agrippa's trilemma
Sceptics say demonstration depends on self-demonstrating things, or indemonstrable things [Diog. Laertius]
     Full Idea: Sceptics say that every demonstration depends on things which demonstrates themselves, or on things which can't be demonstrated.
     From: Diogenes Laertius (Lives of Eminent Philosophers [c.250], 9.Py.11)
     A reaction: This refers to two parts of Agrippa's Trilemma (the third being that demonstration could go on forever). He makes the first option sound very rationalist, rather than experiential.
13. Knowledge Criteria / A. Justification Problems / 3. Internal or External / a. Pro-internalism
Internalists are much more interested in evidence than externalists are [McGrew]
     Full Idea: The notion of evidence generally plays a much more significant role in internalist epistemologies than it does in various forms of externalism.
     From: Timothy McGrew (Evidence [2011], 'Prop..')
     A reaction: I'm guessing that this is because evidence needs a certain amount of interpretation, whereas raw facts (which externalists seem to rely on) may never even enter a mind.
