Nature and Scope of Logic & Basic Concepts of Logic: Terms, Propositions and Arguments
Define logic and distinguish it from psychology and rhetoric in your own words, citing at least three textbook definitions.
Classify ten given statements as term, proposition, or argument, and justify each classification in one sentence.
Break five short passages into premises and conclusion, stating whether each is deductive or inductive.
Explain the difference between truth and validity using two original examples of a valid argument with false premises and an invalid argument with true premises.
Your checkpoint
A one-page classification sheet: 10 statements labelled term/proposition/argument, plus 5 passages with premises, conclusion, and deductive/inductive verdict.
Categorical Propositions and Immediate Inference
Write the four standard-form categorical propositions with their quantity, quality, and distribution patterns from memory.
Convert eight ordinary-language sentences into standard categorical form, resolving unclear terms.
Draw and label the traditional square of opposition and state all four relations (contradictory, contrary, subcontrary, subaltern).
Apply conversion, obversion, and contraposition to six propositions, noting which are validly inferred and which are not.
Your checkpoint
A completed square of opposition diagram plus a table of 6 propositions showing original, converse, obverse, and contrapositive with validity marks.
Syllogistic Reasoning
Identify the mood and figure of ten given syllogisms and write each in standard form.
State the rules of validity for categorical syllogisms and test five syllogisms against every rule, recording which rule each invalid form violates.
Use Venn diagrams to test five syllogisms for validity, shading premises and checking the conclusion.
Distinguish formal from material fallacies that arise inside syllogistic reasoning, such as illicit process and undistributed middle.
Your checkpoint
A syllogism workbook of 10 items: standard form, mood-figure label, rule-by-rule check, Venn diagram verdict, and one-line error diagnosis for each invalid case.
Propositional Logic: Truth Functions and Truth Tables & Symbolic Logic and Logical Connectives
Memorise the truth tables for negation, conjunction, disjunction, conditional, and biconditional and reproduce all five without notes.
Translate fifteen English sentences into propositional symbols, using brackets correctly for scope.
Construct full truth tables for four compound formulas and classify each as tautology, contradiction, or contingent.
Test three pairs of formulas for logical equivalence using truth tables.
Your checkpoint
A timed closed-book quiz of 20 items: 5 truth tables, 10 translations, and 5 equivalence/tautology classifications, scored and corrected.
Methods of Proof and Formal Deduction
List the rules of inference and rules of replacement, and match each to a worked example.
Construct formal proofs for eight arguments, averaging no more than four lines beyond the premises.
Apply conditional proof and indirect proof to at least three arguments where direct proof is awkward.
Diagnose three faulty proofs by naming the misapplied rule at the exact line.
Your checkpoint
A proof portfolio of 8 fully annotated derivations, each line labelled with the rule used, plus written diagnoses of 3 faulty proofs.
Inductive Reasoning and Scientific Method
Distinguish induction from deduction and describe enumeration, analogy, and causal reasoning with one original example each.
Explain Mill's methods of agreement, difference, concomitant variation, and residues, and apply each to a short scenario.
Outline the steps of the hypothetical-deductive method and identify hypothesis, prediction, test, and confirmation in a described experiment.
Critique two weak inductive arguments by identifying sample size, representativeness, or causal confusions.
Your checkpoint
A 400-word written analysis of one everyday causal claim, applying at least two of Mill's methods and stating what evidence would strengthen or defeat it.
Fallacies and Critical Thinking
Build a checklist of at least twelve named fallacies with a definition and a fresh example for each.
Detect and name the fallacy in fifteen short passages, distinguishing formal from informal cases.
Explain the difference between a fallacy and a legitimate persuasive technique, with two borderline examples.
Rewrite three fallacious arguments so that they become logically acceptable.
Your checkpoint
A fallacy reference sheet of 12 named fallacies with definitions and original examples, plus a scored 15-item identification exercise.
Categorical Propositions and Immediate Inference & Syllogistic Reasoning & Propositional Logic: Truth Functions and Truth Tables & Methods of Proof and Formal Deduction
Take two full-length timed mock papers under exam conditions and score them against the official marking scheme.
Re-derive every item missed on the mocks and write the corrected reasoning in a single error log.
Recite distribution patterns, syllogism rules, and truth tables from memory in one uninterrupted session.
Rank domains by mock accuracy and re-drill the two weakest with focused practice sets.
Your checkpoint
Two completed mock papers with scores, plus an error log listing every mistake, its cause, and the corrected rule or method.
Milestones
Week 2: Can state quantity, quality, and distribution for all four categorical propositions and complete the square of opposition from memory with no notes.
Week 4: Scores at least 16/20 on the closed-book truth-table and translation quiz, with all five connective tables correct.
Week 6: Completes 8 formal proofs with at least 6 fully correct and correctly annotated, and scores 12/15 on fallacy identification.
Week 8: Averages at least 70% across two timed mock papers, with no domain below 50% accuracy in the error log.
