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 Canary Islands 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 Do not quote without explaining the quoted terms.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.
