1. Relative and Absolute Statements

Key Concepts & Definitions

  • Relative statement: depends on the context of utterance, such as the date indicated by “today.”
  • Absolute statement: does not depend on the context of utterance, as in “Thursday 10 September 2026.”

Memory Hook

Relative depends on context; absolute does not.

2. Reason, Rationality, and Demonstration

Key Concepts & Definitions

  • Reason: our capacity to reason.
  • Rationality: acting according to logical reasons rather than reacting to feelings and showing moderation.
  • Demonstration: a valid reasoning process in which the conclusion necessarily follows from the premises.
