Ancient and Medieval Philosophy (Plato, Aristotle, Augustine, Aquinas)

  • Plato's theory of Forms: sensible things are imperfect copies participating in eternal, immaterial Forms; knowledge (episteme) is recollection (anamnesis) of the Forms, opinion (doxa) concerns the sensible world.

  • Plato's divided line ranks cognition: eikasia (images), pistis (sensible objects), dianoia (mathematical reasoning), noesis (dialectical grasp of Forms); the Good is the highest Form, analogous to the sun in the cave allegory.

  • Aristotle's four causes: material (hyle), efficient (kinoun), formal (eidos), final (telos); the final cause explains natural processes as directed toward an end.

  • Aristotle's hylomorphism: every sensible substance is a composite of matter and form; form is the actuality (entelecheia) of a potentially existing body, and the soul is the form of a living body.

  • Aristotle distinguishes potentiality (dynamis) from actuality (energeia); change is the actualization of what exists potentially, which answers Parmenides' objection to motion.

  • Augustine's illuminationism: the human mind grasps eternal truths only through divine illumination; truth is interior (in interiore homine habitat veritas) and God is the light by which the mind judges.

  • Augustine on time (Confessions XI): time is a distension of the mind (distentio animi); past exists as memory, present as attention, future as expectation, not as independent realities.

  • Augustine on evil: evil is not a substance but a privation of good (privatio boni); free will (liberum arbitrium) explains moral evil, and grace is required for the will to choose rightly.

  • Aquinas reconciles Aristotle with Christian doctrine: reason and faith are distinct but harmonious, grace perfects nature, and the five ways (quinque viae) argue for God from motion, causation, contingency, gradation, and finality.

Modern Philosophy: Rationalism and Empiricism (Descartes, Hume)

  • Descartes' method of doubt suspends all beliefs that can be doubted; the cogito ('I think, therefore I am') survives because even the evil demon hypothesis presupposes a thinking subject.

  • Descartes' criterion of clear and distinct perception grounds the proof of God; God's veracity guarantees that clear and distinct ideas are true, breaking the circle of relying on God to validate clarity.

  • Cartesian dualism: res cogitans (thinking substance, defined by thought) and res extensa (extended substance, defined by extension) are really distinct; the pineal gland is proposed as the point of interaction.

  • Hume's fork: relations of ideas (a priori, demonstrably certain, e.g. geometry) versus matters of fact (a posteriori, contingent, grounded in experience); only the former carry logical necessity.

  • Hume's copy principle: every simple idea is derived from a preceding impression; ideas without corresponding impressions (e.g. the self as substance) are suspect.

  • Hume on causation: we never perceive a necessary connection between cause and effect, only constant conjunction and temporal priority; the idea of necessity arises from custom or habit of the imagination.

  • Hume's problem of induction: past regularities cannot justify future predictions without assuming the uniformity of nature, which itself cannot be demonstrated without circularity.

  • Hume's bundle theory of the self: introspection reveals only particular perceptions in flux, no persistent ego; personal identity is a fiction generated by resemblance and causality among perceptions.

  • Rationalism versus empiricism: rationalists (Descartes, Spinoza, Leibniz) hold that significant knowledge can be attained by reason alone; empiricists (Locke, Berkeley, Hume) hold that all knowledge originates in experience.

Quick reference

Enlightenment and German Idealism (Kant, Rousseau, Hegel)

  • Kant's Copernican revolution: objects conform to our cognition rather than cognition to objects; space and time are a priori forms of intuition, and the categories are a priori concepts of the understanding.

  • Kant's analytic/synthetic and a priori/a posteriori distinctions combine into synthetic a priori judgments (e.g. arithmetic, causality), which are possible because they structure experience.

  • Kant's phenomena/noumena distinction: we know things only as they appear under our forms of intuition; the thing in itself (Ding an sich) is thinkable but not knowable.

  • Kant's categorical imperative: act only on maxims that could become universal laws; treat humanity always as an end and never merely as a means; the will is autonomous when it legislates this law to itself.

  • Rousseau's social contract: legitimate authority rests on the general will (volonté générale), which aims at the common good; individuals exchange natural liberty for civil liberty and moral freedom under law.

  • Rousseau on the state of nature: humans are naturally free and compassionate (pity), and inequality and vice arise from socialization, property, and amour-propre (self-love based on comparison).

  • Hegel's dialectic: thought and history advance through contradiction and its resolution (thesis, antithesis, synthesis); the negative is a moment internal to the development of the concept (Begriff).

  • Hegel's Phenomenology of Spirit traces the education of consciousness from sense-certainty through self-consciousness (master-slave dialectic) to absolute knowing; Spirit (Geist) is realized in ethical and historical life.

  • Hegel's dictum 'the rational is the real': philosophy grasps its time in thought (the Owl of Minerva flies at dusk); history is the progressive realization of freedom, and the state is the actuality of the ethical idea.

Quick reference

19th- and 20th-Century Philosophy (Marx, Nietzsche, Ortega y Gasset, existentialism)

  • Marx's historical materialism: the mode of production of material life conditions social, political, and intellectual life; social being determines consciousness, not the reverse.

  • Marx's base and superstructure: productive forces plus relations of production form the economic base; law, politics, religion, and ideology constitute the superstructure that the base conditions.

  • Marx on alienation (Entfremdung): under capitalism the worker is estranged from the product, the labor process, species-being, and other humans; surplus value is extracted from unpaid labor time.

  • Nietzsche's critique of morality: slave morality inverts aristocratic values, valorizing weakness and ressentiment; master morality affirms strength and self-overcoming.

  • Nietzsche's will to power (Wille zur Macht) is the fundamental drive of life, not mere domination; nihilism follows from the collapse of higher values, and the Übermensch creates new values.

  • Nietzsche's eternal recurrence is a thought experiment testing affirmation of life: could you will to live this exact life infinitely many times?

  • Ortega y Gasset's perspectivism: 'I am I and my circumstance' (yo soy yo y mi circunstancia); reality is known from a perspective, and truth is the sum of partial perspectives.

  • Ortega's ratio-vitalism (razón vital): reason must be integrated with life; the mass man of the revolt of the masses is the average individual who lives without demanding excellence or responsibility.

  • Sartre's existentialism: existence precedes essence; humans are radically free and responsible, condemned to be free; bad faith (mauvaise foi) is denying freedom by adopting fixed roles.

Text Commentary and Philosophical Vocabulary

  • Identify the passage's thesis, then its argument structure (premises, inference, conclusion); distinguish what the author asserts from what he merely reports or refutes.

  • Contextualize the excerpt: locate it in the author's work and intellectual period, and name the philosophical problem it addresses and the opponent it targets.

  • Explain key technical terms in context (e.g. substance, idea, impression, a priori, general will, alienation), not in isolation, and show how the author uses them.

  • Distinguish types of claim: analytic versus synthetic, a priori versus a posteriori, descriptive versus normative; identify modal claims (necessary, contingent, possible).

  • Detect argumentative moves: reductio ad absurdum, counterexample, thought experiment (evil demon, state of nature, eternal recurrence), and circular reasoning.

  • Evaluate the argument critically: test validity and soundness, check for hidden premises, equivocation, and unstated assumptions.

  • Write the commentary with a clear structure: thesis identification, conceptual analysis, argument reconstruction, critical assessment, and conclusion on the text's significance.

  • Vocabulary precision: 'valid' concerns form, 'sound' adds true premises; 'cause' in Hume is constant conjunction, in Aristotle one of four explanatory factors; do not conflate senses across authors.

Quick reference

Author Comparison

  • Plato versus Aristotle on universals: Plato posits separate transcendent Forms; Aristotle holds forms are immanent in particular substances (universale in re).

  • Descartes versus Hume on the self: Descartes finds a substantial thinking ego through doubt; Hume finds only a bundle of perceptions with no substantial self.

  • Descartes versus Hume on causation: Descartes accepts causal principles as clear and distinct a priori truths; Hume reduces causal necessity to habitual expectation grounded in experience.

  • Kant versus Hume: Kant accepts Hume's claim that causal necessity is not given in sensation but explains it as an a priori category constitutive of experience, not as custom.

  • Kant versus Rousseau on freedom: Rousseau locates moral freedom in obedience to the general will; Kant grounds autonomy in the rational will's self-legislation of the categorical imperative.

  • Hegel versus Kant: Kant's thing in itself and rigid categories are criticized by Hegel, who historicizes the categories and treats contradiction as productive rather than a limit.

  • Marx versus Hegel: Marx retains Hegel's dialectic but inverts it, grounding historical development in material production rather than in Spirit's self-realization.

  • Nietzsche versus Rousseau: Rousseau trusts natural pity and the general will as morally sound; Nietzsche suspects morality itself as a symptom of ressentiment and herd values.

  • Ortega versus Descartes: Descartes begins from the isolated cogito; Ortega insists the self is always self-with-circumstance, so life is the radical reality to be analyzed.

Quick reference

Argumentation and Personal Reasoned Essay

  • Structure the essay: introduction stating the thesis, body paragraphs each defending one premise with textual evidence, and a conclusion that acknowledges limits of the position.

  • Define contested terms (freedom, justice, truth, reality) at the outset; an argument that shifts meanings commits equivocation.

  • Use valid forms explicitly: modus ponens, modus tollens, disjunctive syllogism, and reductio ad absurdum; name the form when reconstructing an author's argument.

  • Distinguish deductive validity from inductive strength; a counterexample defeats a universal claim but not a statistical one.

  • Support claims with precise references to authors and works (e.g. Kant, Groundwork, second formulation) rather than vague appeals to 'philosophers'.

  • Anticipate the strongest objection (steel-man) and reply to it; mere assertion of a contrary view is not a refutation.

  • Avoid genetic and ad hominem fallacies: an argument's truth is independent of its author's motives or biography.

  • Conclude with a qualified thesis: state which parts of the position are established, which remain open, and what evidence would change your view.

Quick reference

Exam Technique and Source Handling

  • For PAU-style text commentary, identify author, work, and period first, then summarize the passage's central thesis in one sentence before analyzing concepts.

  • Quote sparingly and accurately from the passage; paraphrase the argument in your own words to demonstrate comprehension rather than memorized phrasing.

  • Allocate time by weighting: commentary and comparison questions typically demand more developed argument than short definition items.

  • When comparing authors, use explicit contrast markers (unlike, whereas, by contrast) and state the shared problem before the divergence.

  • For the personal reasoned essay, take a defensible position, argue for it, and address at least one serious objection; a balanced but uncommitted summary scores poorly.

  • Define technical vocabulary on first use, especially when translating terms (e.g. Geist, volonté générale, Entfremdung, distentio animi).

  • Connect each author to the domain question asked; do not import irrelevant biography or historical anecdote as a substitute for argument.

  • Check the conclusion against the question: restate the thesis and show how the body's premises support it.

Quick reference

Key Doctrines and Distinctions to Master

  • Plato: knowledge is of Forms, opinion of sensibles; the cave allegory maps education as turning the soul from shadows to the Good.

  • Aristotle: virtue is a mean between extremes determined by practical wisdom (phronesis); the contemplative life is the highest human activity.

  • Augustine: faith seeking understanding (crede ut intelligas); grace precedes and enables meritorious action, against Pelagianism.

  • Aquinas: natural law is the rational creature's participation in eternal law; the four laws are eternal, natural, human, and divine.

  • Descartes: the provisional morality and the method of analysis (reduce to simples) accompany the metaphysical doubt; the res cogitans is known before the body.

  • Hume: the is/ought gap; moral judgments express sentiment, not reason, and reason is the slave of the passions.

  • Kant: the three questions (what can I know, what ought I do, what may I hope) correspond to Critique of Pure Reason, Practical Reason, and Judgment.

  • Hegel: the master-slave dialectic shows self-consciousness requires recognition by another; labor and the fear of death transform the slave's consciousness.

  • Marx and Nietzsche both offer critique of ideology, but Marx diagnoses economic alienation while Nietzsche diagnoses moral and psychological decadence.

Quick reference

Twentieth-Century and Existentialist Themes

  • Ortega's 'I am I and my circumstance' makes life the primary reality; philosophy's task is to articulate the self's relation to its circumstances.

  • Ortega's perspectivism does not entail relativism: each perspective is partial but compatible with a structured reality, and truth emerges from integrating perspectives.

  • Sartre: existence precedes essence means humans first exist and then define themselves through choices; there is no fixed human nature to excuse action.

  • Sartre's bad faith: adopting a role (waiter, coward) as if it were a fixed essence denies the freedom one actually has.

  • Heidegger's Dasein is being-there, characterized by thrownness, projection, and being-toward-death; authenticity requires confronting finitude.

  • Camus' absurd arises from the clash between the human demand for meaning and the world's silence; revolt affirms life without appeal to transcendence.

  • Existentialism's common core: freedom, responsibility, anxiety, and the rejection of fixed essences; differences lie in whether meaning is created or disclosed.

  • Ortega's mass-man and Nietzsche's last man both diagnose mediocrity and conformity as threats to genuine individuality and cultural vitality.

  • Marx's critique of ideology and Nietzsche's genealogy of morals both unmask supposedly neutral values as products of power and historical conditions.

Quick reference

Method, Evidence, and Writing Precision

  • Distinguish exposition from evaluation: first reconstruct the author's argument faithfully, then assess it; conflating the two weakens both.

  • Use primary-text evidence: cite chapter or section (e.g. Hume, Enquiry, Section IV; Kant, Groundwork, Section II) rather than secondary summaries.

  • Define a thesis as a contestable claim, not a topic; 'Hume on causation' is a topic, 'Hume's account reduces causation to habit' is a thesis.

  • Avoid anachronism: do not attribute Kantian categories to Aristotle or Cartesian dualism to Plato; note conceptual differences when comparing across periods.

  • Track the argument's scope: a claim about how we acquire ideas differs from a claim about what exists; keep epistemology and metaphysics distinct.

  • When using thought experiments, state the intuition they are meant to elicit and whether that intuition is reliable.

  • Precision in translation: note original terms (distentio animi, volonté générale, Entfremdung, Wille zur Macht) and their standard English renderings.

  • Revise for clarity: one claim per paragraph, explicit connectives, and no rhetorical questions substituting for argument.

Quick reference

Cross-Cutting Problems and Debates

  • The problem of knowledge: rationalists ground certainty in reason and innate ideas; empiricists in experience; Kant synthesizes both by making experience structured by a priori forms.

  • The problem of freedom: determinism (Hume's compatibilism) versus libertarian freedom (Descartes, Sartre) versus autonomy as self-legislation (Kant, Rousseau).

  • The problem of the self: substance (Descartes), bundle (Hume), historical-spiritual realization (Hegel), embodied circumstance (Ortega), project (Sartre).

  • The problem of God and evil: Augustine's privation theory and Aquinas' five ways versus Hume's evidential problem of evil and Nietzsche's critique of Christian morality.

  • The problem of history: Hegel's teleological progress of freedom versus Marx's materialist dialectic versus Nietzsche's genealogical critique of moral values.

  • The problem of the state: Rousseau's general will, Hegel's ethical state, Marx's class state to be transcended, Ortega's mass society, and existentialist individual responsibility.

  • The problem of language and meaning: from Plato's Forms to Nietzsche's claim that truths are metaphors, and Ortega's integration of reason with vital perspective.

  • The is/ought problem (Hume) underlies later critiques of ideology and morality in Marx and Nietzsche, who explain normative claims by non-normative conditions.

Concepts, Terms, and Definitions

  • Anamnesis (Plato): recollection of the Forms by the soul; learning is remembering what the soul knew before embodiment.

  • Entelecheia (Aristotle): actuality or complete realization; the soul is the entelechy of a naturally organized body.

  • Privatio boni (Augustine): evil as absence or corruption of good rather than a positive substance.

  • Cogito ergo sum (Descartes): the indubitable first truth that a thinking subject exists whenever it thinks.

  • Impression versus idea (Hume): impressions are vivid perceptions of sensation or reflection; ideas are faint copies of impressions in thought.

  • Synthetic a priori (Kant): a judgment that adds to knowledge yet is universally and necessarily valid independent of experience, e.g. 7+5=12.

  • Categorical imperative (Kant): an unconditional moral law binding on all rational agents regardless of desires or consequences.

  • Volonté générale (Rousseau): the will of the citizen body aimed at the common good, distinct from the sum of private wills (volonté de tous).

  • Aufhebung (Hegel): dialectical sublation that cancels, preserves, and elevates a prior moment into a higher unity.

  • Entfremdung (Marx): alienation or estrangement of the worker from the product, process, and essence of labor under capitalism.

  • Wille zur Macht (Nietzsche): the will to power as the fundamental tendency of life toward growth, overcoming, and value creation.

  • Razón vital (Ortega): vital reason, the integration of rational analysis with the concrete circumstances of life.

  • Mauvaise foi (Sartre): bad faith, the self-deception by which one denies one's freedom by adopting a fixed identity.

Quick reference

Argument Reconstruction and Fallacies

  • Modus ponens: if P then Q; P; therefore Q. Modus tollens: if P then Q; not Q; therefore not P. Affirming the consequent and denying the antecedent are invalid.

  • Reductio ad absurdum: assume the negation of the thesis, derive a contradiction, conclude the thesis; used by Descartes (evil demon) and Kant (antinomies).

  • Counterexample defeats a universal claim; a single exception to 'all knowledge derives from experience' refutes the strict empiricist thesis unless qualified.

  • Equivocation: shifting a term's meaning mid-argument, e.g. 'free' as absence of constraint versus 'free' as autonomous self-legislation.

  • Circularity: Descartes' appeal to God's veracity to validate clear and distinct ideas is charged with presupposing what it proves.

  • Genetic fallacy: rejecting a belief because of its origin; Nietzsche's genealogy of morals risks this unless it also shows the values are false.

  • Is/ought gap (Hume): descriptive premises alone cannot entail a normative conclusion; a normative premise must be supplied.

  • Straw man versus steel man: refute the strongest version of the opposing view; misrepresenting it is a fallacy of relevance.

  • Ad hominem and appeal to authority: the author's character or prestige does not establish the truth of the claim.

Quick reference

Essay Planning and Assessment Criteria

  • Thesis statement: one sentence that states a contestable position and previews the argument's structure.

  • Body paragraph template: claim, evidence from primary text, explanation linking evidence to claim, then transition.

  • Use conceptual analysis where the question asks 'what is X': distinguish necessary and sufficient conditions and test with counterexamples.

  • Use comparative analysis where the question asks 'compare A and B': identify the shared problem, then contrast premises, method, and conclusion.

  • Critical evaluation: state the strongest objection, reply on the author's behalf, then judge whether the reply succeeds.

  • Conclusion: restate the qualified thesis and note what further argument or evidence would settle the issue.

  • Assessment favors precision, textual support, and coherent structure over length; irrelevant historical narrative loses marks.

  • Check for internal consistency: do not defend determinism in one paragraph and libertarian freedom in the next without reconciling them.

Quick reference

Historical Context and Influence

  • Plato and Aristotle respond to the Presocratics and Sophists; Plato's Forms answer relativism, Aristotle's empiricism corrects Plato's transcendence.

  • Augustine mediates Platonism and Christianity; Aquinas mediates Aristotle and Christianity, receiving Aristotle through Arabic commentators such as Averroes.

  • Descartes responds to Renaissance skepticism (Montaigne) and founds modern epistemology; his dualism sets the mind-body problem for later thought.

  • Hume's empiricism awakens Kant from dogmatic slumber; Kant's critical philosophy reframes both rationalism and empiricism.

  • Rousseau influences Kant's moral autonomy and the French Revolution's conception of popular sovereignty.

  • Hegel's idealism dominates nineteenth-century thought and provokes reactions from Marx (materialism), Kierkegaard (individual existence), and Nietzsche (genealogy).

  • Marx and Nietzsche shape twentieth-century critique of ideology, culture, and morality.

  • Ortega y Gasset brings German phenomenology and historicism into Spanish-language philosophy and addresses mass society.

  • Sartre and Camus popularize existentialism after World War II, emphasizing freedom, absurdity, and responsibility.

Quick reference

Common Exam Pitfalls

  • Confusing Plato's Forms with Aristotle's forms: the former are separate and transcendent, the latter immanent in substances.

  • Equating Hume's skepticism with total denial of causation; Hume denies perceived necessary connection, not regular succession.

  • Treating Kant's thing in itself as knowable; it is a limiting concept (Grenzbegriff), not an object of possible experience.

  • Reducing Rousseau's general will to majority opinion; the general will aims at the common good and can be misidentified by the majority.

  • Reading Hegel's dialectic as a mechanical thesis-antithesis-synthesis formula; Hegel's own term is speculative or dialectical movement.

  • Attributing to Marx a simple economic determinism; he holds that the economic base conditions but does not mechanically cause all superstructural phenomena.

  • Treating Nietzsche's will to power as mere political domination; it is a broader drive toward growth and self-overcoming.

  • Confusing Ortega's perspectivism with relativism; perspectives are partial but integrate into a structured truth.

  • Confusing Sartre's 'existence precedes essence' with nihilism; it grounds radical responsibility rather than denying all value.

Quick reference

Textual Analysis: Reading and Interpreting Passages

  • Read the passage twice: first for the overall thesis, then for the argument's steps and the function of each sentence.

  • Identify the author's target: whom is the passage arguing against (e.g. skeptics, dogmatists, empiricists, rationalists)?

  • Locate the passage's key term and check whether the author redefines it from ordinary usage (e.g. Hume's 'cause', Kant's 'idea').

  • Reconstruct the argument in premise-conclusion form and test its validity before assessing truth.

  • Note rhetorical devices (irony, metaphor, hyperbole) and explain their argumentative function rather than ignoring them.

  • Explain the passage's significance within the work and the author's broader system.

  • Offer a critical judgment: identify an unstated assumption or a plausible objection and assess the author's resources for replying.

  • Conclude by stating what the passage establishes and what it leaves unresolved.

Quick reference

Comparative Frameworks Across Periods

  • Ancient versus modern: ancient philosophy centers on the good life and cosmic order; modern philosophy centers on the epistemic subject and the foundations of knowledge.

  • Rationalism versus empiricism: innate ideas and deduction versus experience and induction; Kant's synthesis makes experience possible through a priori structures.

  • Enlightenment versus Romantic critique: Enlightenment trusts universal reason and progress; Rousseau and later critics emphasize sentiment, community, and the costs of civilization.

  • Idealism versus materialism: Hegel's Spirit-driven history versus Marx's material base; both use dialectical method but invert its grounding.

  • Teleology versus genealogy: Aristotle and Hegel see purpose in nature and history; Nietzsche and Marx expose values and institutions as historical products.

  • Individual versus collective: Descartes and Sartre begin from the individual; Rousseau, Hegel, and Marx emphasize social and historical constitution.

  • Perspective versus absolute knowledge: Hegel claims absolute knowing; Ortega and Nietzsche insist on perspectival and historically situated knowledge.

  • Freedom as autonomy versus freedom as absence of interference: Kant and Rousseau favor autonomy; Hume and liberals favor non-interference.

Thematic Comparisons: Knowledge and Reality

  • Plato versus Descartes: both seek certainty beyond the senses, but Plato grounds it in transcendent Forms and recollection, Descartes in the cogito and clear and distinct ideas.

  • Aristotle versus Hume on causation: Aristotle treats final and formal causes as real explanatory factors; Hume restricts causation to observed regular succession.

  • Kant versus Plato on the a priori: Plato's a priori truths are recollections of a separate realm; Kant's are structures of the knowing subject that make experience possible.

  • Hume versus Kant on the self: Hume's self is a bundle of perceptions; Kant's transcendental unity of apperception is the formal condition of any unified experience.

  • Hegel versus Kant on reality: Kant limits knowledge to phenomena; Hegel claims the thing in itself is unknowable only because of a false abstract conception of the subject-object relation.

  • Ortega versus Descartes on certainty: Ortega rejects the isolated cogito and begins from the indissoluble unity of self and circumstance.

  • Nietzsche versus Plato on truth: Plato locates truth in immutable Forms; Nietzsche treats truths as metaphors whose status is historical and perspectival.

  • Marx versus Hegel on reality: reality is material and economic for Marx, spiritual and conceptual for Hegel; both see history as dialectical development.

Quick reference

Thematic Comparisons: Ethics and Politics

  • Aristotle versus Kant on ethics: Aristotle's virtue ethics centers on character and the mean determined by phronesis; Kant's deontology centers on duty and the categorical imperative.

  • Rousseau versus Hobbes on the state of nature: Hobbes sees war of all against all requiring absolute sovereignty; Rousseau sees natural freedom and pity corrupted by society.

  • Rousseau versus Kant on freedom: Rousseau's civil freedom is obedience to the general will; Kant's autonomy is the rational will legislating the moral law to itself.

  • Hegel versus Rousseau on the state: Rousseau's general will is abstract and can lead to tyranny of the majority; Hegel's ethical state is the concrete actuality of freedom in institutions.

  • Marx versus Hegel on the state: Hegel treats the state as the actuality of the ethical idea; Marx treats it as an instrument of class rule within the superstructure.

  • Nietzsche versus Kant on morality: Kant grounds morality in universal reason; Nietzsche sees it as a historically contingent valuation rooted in ressentiment.

  • Ortega versus Nietzsche on the individual: both critique mass conformity, but Ortega stresses circumstance and vital reason while Nietzsche stresses value creation and will to power.

  • Sartre versus Kant on freedom: Kant defines freedom as autonomy under the moral law; Sartre defines freedom as the unconditional capacity to choose, with responsibility but no fixed law.

  • Plato and Aristotle agree that humans are rational animals; Plato stresses the tripartite soul (reason, spirit, appetite) and Aristotle the rational activity of the soul.

  • Augustine and Aquinas both hold that humans are made in God's image and oriented to God; Augustine emphasizes grace and the will, Aquinas the harmony of reason and faith.

  • Hobbes and Rousseau differ on natural sociability: Hobbes emphasizes fear and competition; Rousseau emphasizes natural pity and perfectibility.

  • Hegel and Marx both see history as directional and dialectical; Hegel sees the realization of freedom in Spirit, Marx the development of productive forces and class struggle.

  • A priori versus innate: a priori concerns justification independent of experience; innate concerns the origin of ideas in the mind.

  • Analytic versus synthetic: analytic judgments explicate the subject concept; synthetic judgments amplify it.

  • Phenomenon versus noumenon: phenomena are objects as they appear under our forms; noumena are things as they are in themselves.

  • Alienation versus exploitation: alienation concerns estrangement from labor and self; exploitation concerns extraction of surplus value.

Structuring a Strong Comparative Essay

  • Open with the shared problem, then state the contrast thesis that will organize the essay.

  • Devote one paragraph to each author's position on the problem, using primary-text evidence.

  • Add a paragraph of direct comparison identifying the precise point of divergence (premises, method, or conclusion).

  • Assess which position is stronger and why, addressing at least one objection to your preferred view.

  • Show the stakes: explain why the disagreement matters for a broader question (freedom, knowledge, morality).

  • Conclude with a qualified judgment rather than a summary of what was already said.

  • Use consistent terminology across authors and flag where the same word carries different meanings.

  • Avoid parallel but disconnected summaries; every paragraph should advance the comparison.

Final Review: High-Yield Facts and Distinctions

  • The cogito is a performance, not a premise: doubting presupposes a doubter.

  • Kant's synthetic a priori solves the Humean problem by making causality a category constitutive of experience.

  • Rousseau's general will is not the will of all; it aims at the common good and is always right in principle.

  • Hegel's dialectic is not mechanical; contradiction is internal to the concept and is resolved by sublation (Aufhebung).

  • Marx inverts Hegel: the base conditions the superstructure, and alienation is rooted in the labor process.

  • Nietzsche's eternal recurrence is a test of affirmation, not a cosmological doctrine.

  • Ortega's 'I am I and my circumstance' makes life the primary reality and grounds vital reason.

  • Sartre's bad faith is the denial of freedom through a fixed identity; authenticity requires owning one's freedom.
