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.

- Socrates is a man.
- Socrates is mortal.
- Therefore, all men are mortal.
