Assam HS Class 11-12 Logic and Philosophy study plan

Assam HS Class 11-12 Logic and Philosophy · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Categorical Syllogism and Fallacies & Categorical Propositions, Distribution and Immediate Inference

  • Distinguish the four figures of categorical syllogism and identify their valid moods (e.g., Barbara, Celarent) using the traditional mnemonic names.

  • Apply the six rules of the categorical syllogism to detect formal fallacies in given arguments, including illicit major, illicit minor, and undistributed middle.

  • Explain the concept of distribution for A, E, I, and O propositions and determine the distribution status of each term in a proposition.

  • Construct counterexamples to invalid syllogisms by substituting terms while preserving the form.

Your checkpoint

Create a one-page reference sheet listing valid moods for each figure with their mnemonic names and a worked example of a fallacy detection for each of the six rules.

Week 2

Categorical Syllogism and Fallacies & Categorical Propositions, Distribution and Immediate Inference

  • Classify fallacies into formal and informal categories, and identify specific fallacies such as equivocation, amphiboly, composition, division, and petitio principii in short passages.

  • Evaluate extended arguments (3–5 sentences) for multiple fallacies and justify each identification with reference to the definition.

  • Convert ordinary-language arguments into standard categorical form and test their validity using Venn diagrams or rules.

  • Distinguish between immediate inferences (conversion, obversion, contraposition) and mediate inference (syllogism).

Your checkpoint

Complete a set of 10 fallacy-identification exercises (mix of formal and informal) with written explanations, scoring at least 8/10 correct.

Week 3

Nature and Scope of Logic; Logic and Language & Terms, Propositions and Classification of Propositions

  • Define logic and explain its nature and scope, including the distinction between formal and material logic, and between deductive and inductive logic.

  • Analyze the relationship between logic and language: functions of language (informative, expressive, directive) and the distinction between cognitive and emotive meaning.

  • Identify and define terms, and classify terms by comprehension and extension, including singular, general, collective, and abstract terms.

  • Classify propositions by quantity, quality, and relation, and distinguish categorical from hypothetical propositions.

Your checkpoint

Write a 300-word essay explaining how language can obscure logical form, using at least three examples of ambiguous or vague terms.

Week 4

Symbolic Logic: Propositional Calculus and Truth Tables

  • Translate English sentences into propositional calculus using symbols for negation, conjunction, disjunction, conditional, and biconditional.

  • Construct truth tables for compound propositions and determine tautology, contradiction, and contingency.

  • Test the validity of argument forms using the truth-table method (full and short) and identify common valid forms (modus ponens, modus tollens, disjunctive syllogism).

  • Apply the rules of inference and replacement to construct formal proofs of validity.

Your checkpoint

Solve 15 propositional calculus problems: 5 translations, 5 truth-table validity tests, and 5 formal proofs, with at least 12 correct.

Week 5

Inductive Reasoning, Analogy and Scientific Method

  • Distinguish inductive reasoning from deductive reasoning, and explain the problem of induction and the role of probability.

  • Analyze analogical arguments: identify the premises, conclusion, and criteria for strength (relevance, number, and variety of similarities).

  • Describe the steps of the scientific method (hypothesis, observation, experiment, verification) and distinguish between hypothesis and theory.

  • Evaluate the strengths and weaknesses of Mill's methods of experimental inquiry (agreement, difference, concomitant variation, residues).

Your checkpoint

Design a simple experiment or observational study on a topic of your choice, outlining the hypothesis, variables, and which Mill's method is used, in about 200 words.

Week 6

Nature and Branches of Philosophy; Metaphysics and Epistemology

  • Define philosophy and outline its major branches: metaphysics, epistemology, ethics, aesthetics, and logic.

  • Explain key metaphysical concepts: being, substance, causation, and the mind-body problem, with reference to at least two philosophical positions.

  • Compare rationalism and empiricism as epistemological theories, including the roles of reason and experience in knowledge acquisition.

  • Discuss the nature and scope of epistemology: knowledge as justified true belief, and the Gettier problem.

Your checkpoint

Create a comparative table of rationalism vs. empiricism covering key proponents, sources of knowledge, and criticisms.

Week 7

Schools of Indian Philosophy

  • Outline the main schools of Indian philosophy, distinguishing orthodox (āstika) and heterodox (nāstika) systems.

  • Explain the core tenets of Cārvāka, Jainism, and Buddhism, including their views on knowledge, reality, and ethics.

  • Summarize the key doctrines of Sāṃkhya, Yoga, Nyāya, Vaiśeṣika, Mīmāṃsā, and Vedānta (Advaita).

  • Compare the concepts of pramāṇa (means of knowledge) in Nyāya with Western epistemic concepts.

Your checkpoint

Prepare a chart or flashcards for each of the nine schools with their founder, key text, and central doctrine.

Week 8

Nature and Scope of Logic; Logic and Language & Terms, Propositions and Classification of Propositions & Categorical Propositions, Distribution and Immediate Inference & Categorical Syllogism and Fallacies & Symbolic Logic: Propositional Calculus and Truth Tables & Inductive Reasoning, Analogy and Scientific Method & Nature and Branches of Philosophy; Metaphysics and Epistemology & Schools of Indian Philosophy

  • Review all domains by solving a full-length practice test under timed conditions.

  • Identify weak areas from the practice test and revisit those topics using summaries and flashcards.

  • Practice writing concise answers (2–3 sentences) for definitional and explanatory questions.

  • Memorize key Sanskrit terms and their English equivalents for Indian philosophy.

Your checkpoint

Complete a timed mock exam (3 hours) and score at least 70%, with a personalized error log listing mistakes and corrections.

Week 2: Can correctly analyze 8 out of 10 syllogisms for validity and identify the fallacy in 8 out of 10 mixed passages.

Week 4: Can translate 10 English sentences into propositional logic and construct truth tables for 5 compound propositions without errors.

Week 6: Can explain the difference between rationalism and empiricism and list three key proponents of each, and define five metaphysical terms accurately.

Week 8: Achieves at least 70% on the full-length mock exam and has a complete error log with corrections for all mistakes.
