Study Notes

Acquiring Knowledge

  • Knowledge is a mental grasp of reality acquired through observation or reasoning based on observation.
  • Reality: Everything that exists, including our inner world and perceptions.
  • Perception: Our initial contact with reality through senses.
  • Concept: A mental representation of a class or category of things based on shared characteristics.
  • Proposition: A statement that asserts or denies a property or relationship of an existing entity.
  • Inference: Using reasoning to draw conclusions from existing knowledge.
  • Empiricism: Acquiring knowledge through sensory experience. John Locke, George Berkley, and David Hume are prominent empiricists.
  • Rationalism: Acquiring knowledge through reason and logic. René Descartes, Baruch Spinoza, and Gottfried Wilhelm Leibniz are prominent rationalists.
  • Abstraction: Forming higher-level concepts from existing concepts through generalization or subdivision.

Types of Abstraction

  • Widening: Generalizing a concept to include a broader range of entities.
  • Narrowing: Subdividing a concept into smaller, more specific concepts.

Truth and Falsity

  • Truth and falsity are the possible values of a proposition, determining its accuracy.

Example of Inference

  • All men are mortals. This proposition can be demonstrated through an argument:
    • Socrates is a man.
    • Socrates is mortal.
    • Therefore, all men are mortal.
