Historical philosophy foundations and philosophical commentary
This integrated study guide follows shared history-of-philosophy foundations across historical periods and philosophical text analysis. It does not establish a current regional PAU author list, official works, paper format, rubric or difficulty calibration.
Ancient and Medieval Philosophy: Plato, Aristotle, Augustine and Aquinas
What this domain tests
The Ancient and Medieval block asks you to reconstruct doctrines rather than recite biographies. You need Plato's theory of Forms and its epistemological and political consequences, Aristotle's hylomorphism and virtue ethics, Augustine's account of interiority, evil and grace, and Aquinas's synthesis of Aristotle with Christian theology. Text-commentary questions usually supply a short passage and expect term-by-term explanation plus an argument map.
Core rules and concepts
- Plato: the Form (eidos) is separate, eternal, immaterial and knowable by reason; sensible things participate in Forms. The divided line orders images, sensible things, mathematical objects and Forms; the cave allegory links epistemic ascent to political education. The tripartite soul (reason, spirit, appetite) grounds justice as each part doing its own work.
- Aristotle: substances are composites of matter and form; the four causes are material, efficient, formal and final. Virtue is a stable disposition, a mean relative to us, chosen by practical wisdom; eudaimonia is activity of reason in accordance with virtue, not a feeling.
- Augustine: evil is privation of good, not a created substance; free will explains sin, while grace heals the will. Inner experience is the route to God; illumination makes eternal truths intelligible.
- Aquinas: reason and faith are distinct but harmonious; natural law is the rational creature's participation in eternal law; the five ways argue from motion, causation, contingency, perfection and finality, not from a single design premise.
Worked example
Passage: the cave prisoner is released, turns, is dazzled, then ascends. Reasoning: identify the image (cave = visible world; fire = a sun-like source; shadows = appearances); map the stages onto the divided line (eikasia, pistis, dianoia, noesis); explain the pain of turning as the cost of education; connect the returned prisoner's ridicule to the philosopher's political risk. A strong answer distinguishes Plato's claim about reality from mere metaphor and notes that the allegory concerns the whole soul's orientation, not just information transfer.
Traps
Do not say Aristotle simply rejected the Forms: he rejects separate Forms but keeps form as substance. Do not treat Augustinian evil as a thing or as an equal principle. Do not collapse Aquinas's natural law into divine command. Avoid paraphrasing the passage without explaining its argument.
Modern Philosophy: Rationalism and Empiricism (Descartes and Hume)
What this domain tests
The Modern block tests the rationalist-empiricist contrast through two central authors. For Descartes you must explain methodic doubt, the cogito, clear and distinct ideas, the proofs of God and mind-body dualism. For Hume you must explain the impression-idea distinction, the copy principle, the analysis of causation, the problem of induction, the bundle theory of the self and the is-ought gap.
Core rules and concepts
- Descartes: doubt is methodological, not ordinary skepticism. The cogito is performed, not inferred from a syllogism; its certainty rests on the immediate presence of the thinking act. Clear and distinct perception is the criterion of truth, and God's veracity guarantees that what is clearly perceived is true. Mind and body are really distinct substances, yet interact.
- Hume: all simple ideas are copied from impressions; where no impression can be found, the idea is suspect. Relations of ideas are necessary but concern only concepts; matters of fact are contingent and rest on experience. Causation is not observed as a necessary tie: we see constant conjunction, contiguity and succession, and the mind acquires a custom or habit of expectation. The self is a bundle of perceptions, not a substance.
Worked example
Explain why one billiard ball moves another. A Humean analysis proceeds: the first ball's motion is an impression; the second ball's motion is a distinct impression; we observe contiguity and constant conjunction across cases; we never perceive a power or necessary connection. The idea of causal necessity is therefore generated by custom, not copied from an impression. A strong answer adds that Hume does not deny that we make causal judgments; he explains their origin and limits. It also separates the psychological explanation (habit) from the epistemological point (induction cannot be justified non-circularly).
Traps
Do not present the cogito as the premise 'whatever thinks exists' followed by a conclusion. Do not call Descartes a skeptic in the final sense. Do not treat Hume as denying causation in practice or as a dogmatic skeptic; his position is naturalistic. Do not confuse relations of ideas with matters of fact. Avoid summarizing the Meditations without explaining the order of reasons.
Enlightenment and German Idealism: Kant, Rousseau and Hegel
What this domain tests
This block covers the Enlightenment's political and moral turn and the idealist response to Kant. You must explain Rousseau's state of nature, general will and social contract; Kant's Copernican revolution, synthetic a priori knowledge, categories, phenomena and noumena, and the categorical imperative; and Hegel's dialectic, historical reason, master-slave relation and critique of the thing-in-itself.
Core rules and concepts
- Rousseau: natural goodness and perfectibility distinguish humans from animals; inequality arises through property and comparison. The social contract aims at the general will, which concerns the common good and is not the sum of particular wills. Freedom is obedience to a law one gives oneself.
- Kant: experience is structured by forms of intuition (space, time) and pure concepts (categories); synthetic a priori judgments are possible because the object of experience is constituted in part by our cognition. We know phenomena, not things in themselves. The categorical imperative tests maxims for universalizability and treats humanity as an end in itself; autonomy is the ground of dignity.
- Hegel: thought and being are not separated by an unknowable remainder; the absolute is reached through dialectical development. Self-consciousness arises through recognition in the master-slave struggle; history is rational in retrospect, and Aufhebung cancels, preserves and elevates earlier stages.
Worked example
Test the maxim 'I will make a false promise when in difficulty.' Universalize it: a practice of promise-keeping could not survive universal deception, because the institution of promising would collapse. The maxim is contradictory in conception, so it fails the first formulation. The second formulation adds that using the promisee merely as a means violates humanity as an end. Notice that the test is formal and a priori; consequences are irrelevant to the contradiction. Contrast a hypothetical imperative, which depends on a desired end, with the categorical imperative, which binds unconditionally.
Traps
Kant is not a subjective idealist who says anything goes; the categories are universal conditions. Rousseau's general will is not majority opinion or the aggregation of private interests. Hegel's dialectic is not the mechanical formula thesis-antithesis-synthesis, which is a later textbook simplification. Do not claim Hegel makes the state the highest value without qualification, or that 'absolute knowledge' means omniscience.
19th- and 20th-Century Philosophy: Marx, Nietzsche, Ortega y Gasset and Existentialism
What this domain tests
The contemporary block tests historically situated critiques of modern philosophy. For Marx you need historical materialism, alienation, ideology and surplus value. For Nietzsche, the will to power, genealogy of morals, revaluation, eternal recurrence and perspectivism. For Ortega, vital reason, circumstance, perspectivism and the mass man. Existentialism contributes existence precedes essence, freedom, bad faith, anguish and being-toward-death.
Core rules and concepts
- Marx: the base is the mode of production; the superstructure includes law, politics and culture. Consciousness is shaped by social being, but ideology masks class interests. Alienation has four dimensions: from the product, the labor process, species-being and other persons. Surplus value is extracted when unpaid labor exceeds the value of wages.
- Nietzsche: morality is genealogically examined; master morality values strength and nobility, slave morality revalues weakness as goodness. The death of God exposes the need for revaluation. Will to power is not mere domination but the drive to expand and overcome; eternal recurrence is a test of affirmation; perspectivism denies a God's-eye view without collapsing into relativism.
- Ortega: 'I am myself and my circumstance' makes life the primary reality; vital reason combines biography and history. Perspectivism holds that each perspective is partial but real. Mass man is the uninhibited average person who demands rights without responsibilities.
- Existentialism: for Sartre, existence precedes essence; freedom is radical, and bad faith is the denial of freedom. Heidegger's being-toward-death individualizes existence.
Worked example
Analyze factory labor with Marx's alienation. The worker does not own the product, so it confronts him as an alien power (product). The process is externally controlled, so activity is not self-realization (process). Labor does not express human species-being as conscious, free production (species-being). Competition and exchange estrange persons from one another (others). Then link this to ideology: the wage form appears to pay for all labor, concealing surplus value. A strong answer distinguishes description from normative critique and notes that Marx does not reduce all culture to economics mechanically.
Traps
Nietzsche is not a Nazi prophet; his sister's editing distorted the Nachlass. Ortega's perspectivism is not skepticism: perspectives disclose reality partially. Marx is not a simple economic determinist who denies relative autonomy to politics and culture. Sartrean freedom is situated, not omnipotent. Do not turn existentialism into quietism.
Text Commentary, Philosophical Vocabulary, Author Comparison and the Reasoned Essay
What this domain tests
This cross-cutting guide practises commentary on a short philosophical text, precise technical vocabulary, author comparison and a reasoned essay. These are shared study skills, not a claim about the current regional PAU paper, official rubric or required author list.
Core rules and concepts
- Commentary: identify the author, work and thesis in one sentence; reconstruct the argument as premises leading to a conclusion; explain technical terms in context; evaluate one assumption. Quote only what you analyze.
- Vocabulary: eidos (Form), hylomorphism (matter-form composite), cogito (the thinking thing's immediate certainty), tabula rasa (the mind as initially blank), a priori/a posteriori (order of justification versus experience), categorical imperative (unconditional moral law), Aufhebung (cancel-preserve-elevate), alienation (estrangement from product, process, species-being and others), will to power (self-overcoming drive), circumstance (Ortega's historical and vital situation).
- Comparison: choose explicit axes, such as the origin of ideas, the criterion of truth, the scope of reason or the basis of morality. State the disagreement, then the shared premise. Do not write two separate summaries.
- Essay: state a thesis, define terms, argue with premises, raise the strongest objection, reply, and conclude. Use authors as evidence for a position, not as decoration.
Worked example
Question: compare Descartes and Hume on the origin of ideas. Axes: source, certainty and method. Descartes holds that some ideas are innate and that clear and distinct perception grounds science; Hume holds that simple ideas are copied from impressions and that matters of fact rest on custom. The shared premise is that philosophy must begin from an examination of the mind's contents. The disagreement concerns whether reason can grasp necessary structure independent of experience. Assess: Hume's copy principle challenges innate ideas, but Descartes can reply that the cogito is not a copy of an impression. Conclude with a criterion for judging the debate, not a vague 'both are important'.
Traps
Do not narrate lives instead of arguments. Do not quote without explaining the quoted terms. Do not ignore the comparative instruction by summarizing one author after the other. Avoid anachronism, such as reading Kant's transcendental into Plato. In the essay, do not substitute personal conviction for premises; a thesis without a counterargument is incomplete.
