Karnataka II PUC Logic (KSEAB) study plan
Karnataka II PUC Logic (KSEAB) · Give each week a clear focus.
8 weeks · About 6 hours per week
Categorical Syllogism and Fallacies & Categorical Propositions and Immediate Inference
State the rules of validity for categorical syllogism (distribution of terms, rules of quality and quantity) and apply them to decide validity of at least ten standard-form syllogisms
Rewrite everyday arguments into standard form (major premise, minor premise, conclusion) and identify the mood and figure of each
Distinguish formal from informal fallacies and name the specific fallacy in ten given passages
Construct Venn diagrams for two-term and three-term categorical statements and use them to test validity
Your checkpoint
A handwritten or typed sheet of 20 syllogisms with mood, figure, validity verdict, and the rule violated for each invalid one, scored against an answer key
Categorical Propositions and Immediate Inference & Terms, Propositions and Classification
Classify categorical propositions by quantity and quality and write their A, E, I, O forms with standard quantifier wording
State and apply the traditional square of opposition to derive contradictories, contraries, subcontraries, and subalterns
Perform conversion, obversion, and contraposition on given propositions and label each as valid or invalid
Identify and correct defects in definition (too broad, too narrow, circular, ambiguous) in given examples
Your checkpoint
A completed inference table showing all four relations and all three immediate-inference operations for ten given propositions, with validity marks
Categorical Syllogism and Fallacies & Methods of Proof and Truth Tables
Translate natural-language arguments with 'only', 'unless', 'all but', and 'none but' into standard categorical form
Detect the fallacies of undistributed middle, illicit major, illicit minor, and four terms in prepared arguments
Reduce an enthymeme to its missing premise and test the completed argument
Write out the full truth-table test for validity on simple two-variable arguments
Your checkpoint
A one-page error log listing each syllogistic fallacy with your own original example and the rule it breaks, plus five enthymemes completed and tested
Symbolic Logic: Propositional Calculus & Methods of Proof and Truth Tables
Symbolize compound statements using negation, conjunction, disjunction, conditional, and biconditional with consistent notation
Build complete truth tables for statements with up to three variables and classify them as tautology, contradiction, or contingent
Test argument validity by the indirect (short) truth-table method
Distinguish inclusive from exclusive disjunction and material from ordinary implication in given sentences
Your checkpoint
A timed set of 15 truth tables (at least five with three variables) fully worked with a tautology/contingency/contradiction verdict for each
Symbolic Logic: Propositional Calculus & Methods of Proof and Truth Tables
Apply the rules of inference (modus ponens, modus tollens, hypothetical syllogism, disjunctive syllogism, constructive and destructive dilemma, simplification, conjunction, addition) in multi-step proofs
Apply the rules of replacement (De Morgan, commutation, association, distribution, double negation, transposition, exportation, material implication, equivalence) to transform formulas
Construct formal proofs of validity for at least eight symbolized arguments
Use conditional proof and indirect proof where direct derivation is awkward
Your checkpoint
Eight complete formal proofs written line by line with the justification cited for every step, checked against a key
Inductive Reasoning and Scientific Method
Distinguish induction from deduction and identify kinds of induction: enumeration, analogy, causal inference, and statistical generalization
Explain Mill's methods (agreement, difference, joint method, concomitant variation, residues) and match them to described experiments
Outline the steps of the scientific method and the roles of hypothesis, prediction, experiment, and confirmation
Identify weaknesses in inductive arguments such as hasty generalization, false cause, and biased sample
Your checkpoint
A written analysis of three short scientific or everyday scenarios naming the inductive method used and evaluating the strength of the conclusion
Nature and Scope of Logic & Logic and Language
Define logic, state its nature as a normative science of reasoning, and explain its relation to psychology and grammar
Distinguish sentence, proposition, and statement, and identify the cognitive and emotive uses of language
Explain the functions of language (informative, expressive, directive, performative) and detect emotive and persuasive uses in given passages
Identify and correct ambiguity, vagueness, and equivocation in given examples
Your checkpoint
A short essay of about 300 words distinguishing logic from psychology and grammar, with three original examples of language functions
Categorical Syllogism and Fallacies & Symbolic Logic: Propositional Calculus & Inductive Reasoning and Scientific Method & Categorical Propositions and Immediate Inference
Review all eight domains using a checklist and re-solve one representative problem from each
Take two full-length timed mock papers under exam conditions and score them
Analyze every wrong answer, tracing it to a specific rule, definition, or symbolization error
Memorize the standard rule sets, square of opposition, and fallacy names for quick recall
Your checkpoint
Two scored mock papers with a corrected-answer review sheet listing each error, its cause, and the rule to recall
Milestones
Week 2: Can classify any categorical proposition, state all square-of-opposition relations, and perform conversion, obversion, and contraposition without notes
Week 4: Can symbolize a compound sentence and complete a three-variable truth table correctly in under ten minutes
Week 6: Can name and justify the inductive method in a described scenario and identify the fallacy in a weak inductive argument
Week 8: Scores at least 70 percent on both timed mock papers and can explain every error on the review sheet
