To promote random chance in choosing principles
To separate economic considerations from political ones
To guarantee fair and impartial agreement on justice principles

    Break down complex arguments and identify underlying premises, helping you tackle exam-style prompts with confidence.

  3. Apply critical thinking to philosophy practice problems -

    Use logical reasoning and analytical skills to solve scenarios that challenge your comprehension and creativity.

  4. Evaluate philosophical positions -

    Assess the strengths and weaknesses of different viewpoints, refining your ability to form well-supported judgments.

  5. Identify knowledge gaps -

    Pinpoint areas where you need further study or review, enabling targeted improvement in your philosophical understanding.

Cheat Sheet

  1. Socratic Method & Critical Inquiry -

    Master the art of asking and answering questions to expose assumptions and refine arguments, as detailed by the Stanford Encyclopedia of Philosophy. Use the "Five Whys" mnemonic - keep asking "Why?" up to five times to drill down to core premises. This technique is a staple in philosophy exam questions and philosophy practice problems related to argument analysis.

  2. Cartesian Doubt & Cogito Ergo Sum -

    Review René Descartes' method of systematic skepticism leading to the indubitable truth "I think, therefore I am" (Cogito, ergo sum). Recall the mnemonic C²: Cartesian Critique and Cogito Certainty to remember both the process of doubt and the foundational self-awareness conclusion. This concept is often tested in questions on epistemology and philosophical health checks.

  3. Kant's Categorical Imperative -

    Understand Immanuel Kant's principle: "Act only according to that maxim whereby you can at the same time will that it should become a universal law." A handy formula is KU = Kant's Universalization rule. Practice by evaluating real-life scenarios - like whether lying to protect a friend can be universalized - to sharpen your ethical reasoning for philosophy test scenarios.

  4. Utilitarianism & Greatest Happiness Principle -

    Familiarize yourself with Jeremy Bentham and John Stuart Mill's calculus: maximize overall pleasure and minimize pain. Use the simple equation U = Σ (Happiness) - Σ (Pain) to score choices in practice problems. Academic sources like Oxford's utilitarianism entries provide case studies to practice quantifying utility in exam-style questions.

  5. Logical Fallacies & Argument Structure -

    Distinguish between formal fallacies (e.g., Affirming the Consequent: "If P then Q; Q; therefore P") and informal ones (e.g., Straw Man). The FACA mnemonic - Formal Affirmation, Contradiction, and Analogies - helps you spot errors quickly. Review the Toulmin model (claim, grounds, warrant) for constructing solid responses in philosophy exams and practice problems.
