Western Philosophy: Greek Thought to Modern and Contemporary Positions
From Greek to modern
Pre-Socratics sought an arche; Plato distinguished Forms from sensible things; Aristotle used four causes and treated virtue as habituation. Medieval thought integrated faith and reason. Descartes' methodic doubt reached cogito; rationalists trusted reason; empiricists traced knowledge to experience; Kant united both by asking how experience is possible.
Core positions
- Plato: knowledge of Forms, not mere opinion.
- Aristotle: substances and teleology; eudaimonia through virtue.
- Descartes: mind-body dualism; clear and distinct ideas.
- Hume: impressions and ideas; causation as custom.
- Kant: synthetic a priori; categories structure experience.
- Later: Hegel's dialectic, existentialism, analytic philosophy, postmodern critiques.
Worked example
Hume asks what we observe when one billiard ball hits another. We see motion, contact and regularity, not a necessary connection. Reasoning: constant conjunction plus habit explains our expectation, so causal necessity is not a perceived impression. Kant replies that causation is a category presupposed by ordered experience, not a copy of an impression. A good answer states both and evaluates the inference.
Traps
- Calling Kant a Berkeleyan idealist; he is a transcendental idealist and empirical realist.
- Reducing rationalism to no experience and empiricism to no reason.
- Treating Nietzsche or postmodernism as simple denial of truth.
