  • UGC NET Political Science Unit-6 India’s Foreign Policy

    I. Perspectives on India’s Foreign Policy

    India’s foreign policy reflects its unique history, culture, geography, and global aspirations.
    It has evolved from postcolonial idealism to pragmatic engagement with the global economy and power politics.

    1️⃣ India as a Postcolonial State

    • After independence (1947), India emerged from centuries of British colonial rule.

    • It sought strategic autonomy — freedom from domination by any major power bloc.

    • India emphasized anti-colonialism, anti-imperialism, and equality among nations.

    • This was visible in:

      • Support for decolonization movements in Asia and Africa.

      • Opposition to apartheid in South Africa.

      • Advocacy of Non-Alignment in the Cold War.

    Key Idea: India’s foreign policy is rooted in the colonial experience and a desire to maintain independence in global affairs.

    2️⃣ India as a Developing Nation

    • India’s main challenge after independence was economic underdevelopment.

    • Hence, foreign policy was linked to developmental goals:

      • Seeking foreign aid and technology without compromising sovereignty.

      • Promoting South–South cooperation with other developing countries.

      • Participating in the Group of 77 (G-77) for equitable global economic order.

    Core principle: Economic growth and social justice are integral to external relations.

    3️⃣ India as a Rising Power

    • In the 21st century, India is recognized as a rising power due to:

      • Rapid economic growth (world’s 5th largest economy).

      • Technological and defense advancements.

      • Global leadership roles (e.g., G-20, BRICS, UN peacekeeping).

    • India now aims to shape global rules rather than just follow them.

    Example: India’s leadership in International Solar Alliance (ISA) and Voice of Global South Summit (2023).

    4️⃣ India as an Emerging Political Economy

    • Economic liberalization (1991) transformed India’s foreign relations.

    • Shift from inward-looking to open, globalized economy.

    • Priorities now include:

      • Attracting investment.

      • Expanding exports.

      • Securing energy and technology.

      • Engaging with global markets (WTO, IMF, World Bank).

    Key concept: India’s diplomacy today balances economic interests with strategic partnerships.

    🇮🇳 II. Continuity and Change in India’s Foreign Policy

    1️⃣ Basic Principles (Continuity)

    Articulated by Jawaharlal Nehru, India’s first Prime Minister:

    Principle Explanation
    Panchsheel (1954) Five principles of peaceful coexistence — mutual respect, non-interference, equality, mutual benefit, peaceful coexistence.
    Non-alignment Avoiding military alliances during the Cold War.
    Anti-colonialism & Anti-racism Support for liberation and equality movements.
    Peaceful coexistence Settlement of disputes through diplomacy.
    International law & UN Charter Commitment to rule-based international order.

    These principles continue to guide India, though interpreted pragmatically today.

    2️⃣ Determinants of India’s Foreign Policy

    India’s foreign policy decisions are influenced by:

    Determinant Description
    Geography Shared borders with China, Pakistan, and Indian Ocean location make security vital.
    History Colonial legacy and nonalignment mindset.
    Political system Democracy emphasizes public opinion and soft power.
    Economic interests Trade, technology, investment priorities.
    Leadership Nehru, Indira Gandhi, Vajpayee, Manmohan Singh, and Modi shaped key directions.
    International environment Cold War, globalization, U.S.-China rivalry.

    ☮️ III. Non-Alignment Movement (NAM)

    1️⃣ Historical Background

    • Emerged during the Cold War when the world was divided into:

      • Western bloc (U.S.-led)

      • Eastern bloc (Soviet-led)

    • India, under Nehru, chose an independent path — neither joining NATO nor the Soviet bloc.

    • NAM officially founded in 1961 (Belgrade Summit) by Nehru (India), Tito (Yugoslavia), Nasser (Egypt), Sukarno (Indonesia), Nkrumah (Ghana).

    2️⃣ Objectives of NAM

    • Preserve independence and sovereignty.

    • Promote peace, disarmament, and development.

    • Oppose colonialism and racism.

    • Support South–South cooperation.

    3️⃣ Relevance Today

    • NAM still represents strategic autonomy and multipolar cooperation.

    • India uses NAM as a platform for:

      • Climate justice

      • Reforming global institutions

      • Protecting developing nations’ interests.

    Contemporary meaning: “Issue-based alignment” — India engages flexibly, not rigidly non-aligned.

    ☢️ IV. India’s Nuclear Policy

    • India adopted a No First Use (NFU) policy — will not use nuclear weapons unless attacked first.

    • Peaceful Nuclear Explosion (1974) at Pokhran under Indira Gandhi.

    • Nuclear tests (1998) under Atal Bihari Vajpayee → declared India a nuclear weapons state.

    • Doctrine: Credible Minimum Deterrence + NFU.

    • India refuses to sign NPT and CTBT citing discriminatory nature.

    India’s goal: Nuclear capability for deterrence, not aggression.

    🌏 V. India’s Relations with Major Powers

    1️⃣ India–USA Relations

    • Strained during Cold War (India–USSR closeness, U.S.–Pakistan alliance).

    • Improved after 1991 economic reforms and end of Cold War.

    • Key developments:

      • Nuclear deal (2008) – recognized India’s nuclear status.

      • QUAD partnership (India–U.S.–Japan–Australia).

      • Cooperation in defense (COMCASA, LEMOA), technology, and climate.

    Current Status: Strategic partnership focusing on Indo-Pacific stability and countering China.

    2️⃣ India–USSR / Russia Relations

    • Historic friendship during Cold War; USSR supported India in 1971 war (Bangladesh liberation).

    • Post-Soviet era: Russia remains key defense partner.

    • Joint ventures: BrahMos missile, nuclear submarines, energy cooperation.

    • Despite India’s U.S. engagement, Russia remains a trusted partner.

    3️⃣ India–China Relations

    • Initially friendly under Panchsheel (1954) → later tension over Tibet and borders.

    • 1962 War: major setback.

    • Recent issues: Doklam (2017), Galwan Valley clash (2020).

    • Trade remains strong, but strategic distrust persists.

    • India balances China through QUAD, Indo-Pacific strategy, and ties with ASEAN.

    🌐 VI. India’s Engagement with a Multipolar World

    1️⃣ India–European Union (EU)

    • Major trade and investment partner.

    • Cooperation on climate change, digitalization, and global governance.

    • Negotiating Free Trade Agreement (FTA).

    2️⃣ BRICS (Brazil, Russia, India, China, South Africa)

    • Focus on multipolarity, development, financial reform.

    • Created New Development Bank (NDB).

    • India uses BRICS for South–South solidarity.

    3️⃣ ASEAN (Association of Southeast Asian Nations)

    • Key partner in India’s Act East Policy.

    • Cooperation in trade, connectivity, and maritime security.

    • Example: India–ASEAN Free Trade Agreement (2009).

    4️⃣ Shanghai Cooperation Organisation (SCO)

    • India joined in 2017 with Pakistan.

    • Platform for cooperation with China, Russia, Central Asia on terrorism and energy.

    5️⃣ African Union (AU) & SADC

    • Focus on capacity building, trade, and development projects.

    • India–Africa Forum Summits strengthen South–South partnership.

    6️⃣ Gulf Cooperation Council (GCC)

    • Economic ties: energy imports, remittances from Indian diaspora.

    • Strategic interest in Middle East stability.

    🌏 VII. India’s Relations with Neighbourhood

    1️⃣ SAARC (South Asian Association for Regional Cooperation)

    • Formed in 1985 to promote regional cooperation.

    • Members: India, Pakistan, Bangladesh, Sri Lanka, Nepal, Bhutan, Maldives, Afghanistan.

    • India supports SAARC but progress hindered by India–Pakistan tensions.

    2️⃣ Gujral Doctrine (1996–97)

    Proposed by PM I.K. Gujral — principles for friendly relations with neighbours:

    • Unilateral concessions to smaller neighbours.

    • Non-interference and respect for sovereignty.

    • Mutual trust and cooperation.
      (Example: India–Bangladesh water-sharing agreements.)

    3️⃣ Look East / Act East Policy

  • UGC NET Paper 1 – UNIT 6 — LOGICAL REASONING

    (For NTA UGC NET Paper I: Teaching & Research Aptitude)

    🎯 1. Purpose of this Unit

    Logical reasoning checks your ability to analyse arguments, evaluate evidence, and draw valid conclusions.
    In NET Paper 1, questions test:

    • The structure of reasoning (statements, premises, conclusions)

    • Valid vs invalid arguments

    • Categorical logic (propositions, syllogisms, square of opposition)

    • Inductive vs deductive logic

    • Venn-diagram validity tests

    • Indian logic (pramāṇas and hetvābhāsas)

    🧠 2. Understanding Arguments

    2.1 Structure of an Argument

    An argument is a group of statements where one (the conclusion) is claimed to follow from the others (the premises).

    Example
    Premise 1: All students are learners.
    Premise 2: Ravi is a student.
    ∴ Conclusion: Ravi is a learner.

    Term Meaning
    Premise Evidence / reason offered
    Conclusion Claim drawn from premises
    Indicator words Therefore, Hence, Thus → conclusion; Since, Because → premise

    ⚙️ 3. Argument Forms

    3.1 Deductive Reasoning

    • Moves from general to specific truth.

    • If premises true → conclusion must be true.

    • Validity matters, not factual truth.

    Form:
    All A are B. All B are C. ∴ All A are C.
    ✅ Valid Syllogism

    3.2 Inductive Reasoning

    • From particular to general.

    • Conclusion probable, not certain.
      Example: Observed 100 swans white ⇒ “All swans are white.”

    3.3 Abductive Reasoning

    • Inference to best explanation.
      Example: Wet road ⇒ Probably rained.

    🔢 4. Categorical Propositions

    A categorical proposition relates two categories (subject & predicate).

    Type Form Example Quantity Quality
    A All S are P All dogs are animals Universal Affirmative
    E No S are P No dogs are cats Universal Negative
    I Some S are P Some students are athletes Particular Affirmative
    O Some S are not P Some students are not athletes Particular Negative

    🧩 5. Classical Square of Opposition

    A (All S are P) ──contradictory── O (Some S are not P)
    │ \‾‾‾‾‾‾‾‾‾‾‾/ │
    │ contrary │
    │ │
    E (No S are P) ──contradictory── I (Some S are P)
    Relation Meaning
    Contradictory Opposite truth values (A ↔ O, E ↔ I)
    Contrary Both cannot be true (A & E)
    Sub-contrary Both cannot be false (I & O)
    Sub-alternation Truth flows downward (A → I; E → O)

    ⚖️ 6. Mood and Figure of Syllogism

    6.1 Mood

    Type sequence of propositions (A/E/I/O) for major, minor, conclusion.
    Example AAA (Barbara), EAE (Celarent).

    6.2 Figure

    Determined by position of the middle term (M).

    Figure Form Example
    1st M–P / S–M ⇒ S–P All men are mortal; Socrates is man ⇒ Socrates mortal.
    2nd P–M / S–M ⇒ S–P No reptile is warm-blooded; All snakes are reptiles ⇒ No snake is warm-blooded.

    🧮 7. Fallacies (Errors in Reasoning)

    7.1 Formal Fallacies (logical structure)

    • Affirming the consequent: p→q, q ⇒ p ❌

    • Denying the antecedent: p→q, ¬p ⇒ ¬q ❌

    7.2 Informal Fallacies (content errors)

    • Ad hominem: attacking person not argument.

    • Straw man: misrepresenting opponent’s claim.

    • False cause (post hoc): assuming A→B because A came first.

    • Circular reasoning: premise repeats conclusion.

    • Appeal to authority: treating authority as proof.

    💬 8. Language: Connotation and Denotation

    Term Meaning Example
    Denotation Literal dictionary meaning “Rose” = flower species
    Connotation Emotional or associated meaning “Rose” = love, beauty

    🔄 9. Analogies

    • Show relation similarity between two pairs.
      Example: Finger : Hand :: Toe : Foot
      Test → Find the same logical relationship (type, function, degree).

    🔷 10. Venn Diagrams & Testing Validity

    • Circles represent sets of objects.

    • Use to verify syllogistic arguments.

    Example:
    All A are B, All B are C ⇒ All A are C ✅
    Draw A inside B, B inside C.

    Common patterns:

    • Overlapping circles → “some”

    • Separate circles → “none”

    • Nested circles → “all”

    🪶 11. Indian Logic (Ānvīkṣikī Tradition)

    11.1 Pramāṇa — Means of Valid Knowledge

    1. Pratyakṣa (Perception): Direct sense experience.

    2. Anumāna (Inference): Reasoning from sign to proposition.

    3. Upamāna (Comparison): Knowledge through similarity.

    4. Śabda (Verbal Testimony): Trustworthy authority or scripture.

    5. Arthāpatti (Postulation / Implication): Presumption to explain facts.

    6. Anupalabdhi (Non-apprehension): Knowledge of absence.

    11.2 Structure of Anumāna (Inference)

    Traditional five steps (Nyāya syllogism):

    1. Pratijñā (Statement): Hill has fire.

    2. Hetu (Reason): Because it has smoke.

    3. Udāharaṇa (Example): Where there is smoke, there is fire (kitchen).

    4. Upanaya (Application): Like that, this hill has smoke.

    5. Nigamana (Conclusion): Therefore hill has fire.

    11.3 Vyāpti (Invariable Relation)

    • Universal relation between hetu (reason) and sādhya (conclusion).

    • Example: Smoke → Fire (always co-exist).

    11.4 Hetvābhāsas (Fallacies of Inference)

    Type Nature Example
    Asiddha Unproven reason Sky lotus fragrant (but no lotus exists).
    Viruddha Contradictory reason Fire is cold because it is fire.
    Satpratipakṣa Counter-reason Hill has no fire because there is water.
    Bādhita Opposed by perception Fire is cool (conflicts with experience).
    Anaikāntika Inconclusive / non-exclusive Crow visible ⇒ daytime (not always).

    🧭 12. Evaluating Deductive vs Inductive Reasoning

    Feature Deductive Inductive
    Direction General → Specific Specific → General
    Strength Certainty (if valid) Probability only
    Basis Logic of form Observation & pattern
    Example All humans mortal → Socrates mortal 100 crows seen black → All crows black

    🔍 13. Common Question Types in NET

    1. Identify valid/invalid argument.

    2. Determine type of proposition (A/E/I/O).

    3. Find contradictory statement.

    4. Use Venn diagram for syllogism.

    5. Spot logical fallacy.

    6. Apply Indian logic (pramāṇa, hetvābhāsa).

    7. Match deductive/inductive features.

  • UGC – NET – UNIT V: MATHEMATICAL REASONING AND APTITUDE

    (For NTA UGC NET Paper-I)

    🧠 1. Introduction

    Mathematical Reasoning and Aptitude form the logical and quantitative base of human thinking.
    This unit tests your ability to think logically, recognize patterns, and solve problems using mathematical concepts.

    It is not about complex mathematics, but about how numbers and logic work together in reasoning, argument, and decision-making.

    🎯 2. Key Components of the Unit

    The unit has two parts:

    1. Mathematical Reasoning → Deals with logic, arguments, statements, validity, and reasoning patterns.

    2. Mathematical Aptitude → Deals with numbers, arithmetic operations, ratios, percentages, averages, profit-loss, interest, time-work, etc.

    ⚙️ 3. MATHEMATICAL REASONING

    🔹 3.1. Statements

    A statement is a declarative sentence that is either True (T) or False (F), but not both.

    Examples:

    • “2 + 2 = 4” → True statement

    • “All squares are circles” → False statement

    • “Please close the door” → Not a statement (imperative sentence)

    🔹 3.2. Logical Connectives

    Symbol Connective Meaning Example Truth Condition
    ¬p Negation “Not p” If p = It rains → ¬p = It does not rain Opposite truth value
    p ∧ q Conjunction “p and q” It rains and it’s cold True only if both true
    p ∨ q Disjunction “p or q” (inclusive) It rains or it’s cloudy True if at least one is true
    p → q Implication “If p then q” If it rains, the ground gets wet False only if p is true and q is false
    p ↔ q Bi-conditional “p if and only if q” Two statements true together True when both have same truth value

    🔹 3.3. Truth Tables

    p q p ∧ q p ∨ q p → q p ↔ q
    T T T T T T
    T F F T F F
    F T F T T F
    F F F F T T

    🔹 3.4. Types of Reasoning

    1. Deductive Reasoning:

      • From general to specific.

      • If premises are true, conclusion must be true.

      • Example:
        All teachers are educated.
        Anshuman is a teacher.
        ∴ Anshuman is educated.

    2. Inductive Reasoning:

      • From specific to general.

      • Based on observation and probability.

      • Example:
        The sun rose every day so far → it will rise tomorrow. (probable)

    3. Analogical Reasoning:

      • Drawing comparison between two situations.

      • Example:
        “Hand is to glove as foot is to sock.”

    4. Abductive Reasoning:

      • Inferring the most likely explanation.

      • Example:
        Wet roads → it probably rained.

    🔹 3.5. Arguments and Validity

    An argument consists of premises and a conclusion.
    It is valid if the conclusion logically follows from the premises.

    Example:
    Premise 1: If it rains, the match is canceled.
    Premise 2: It is raining.
    Conclusion: Therefore, the match is canceled. ✅ (Valid)

    🔹 3.6. Syllogism

    A syllogism is a form of logical reasoning with two premises and a conclusion.

    Example:
    All roses are flowers.
    All flowers are plants.
    ∴ All roses are plants.

    🔹 3.7. Fallacies (Logical Errors)

    • Affirming the consequent:
      If it rains, road is wet. Road is wet → therefore it rained ❌ (not necessarily)

    • Denying the antecedent:
      If it rains, road is wet. It did not rain → road not wet ❌

    🧮 4. MATHEMATICAL APTITUDE

    Focus: Numerical ability, calculation, and quantitative logic.

    🔹 4.1. Numbers and Operations

    • Even numbers: divisible by 2

    • Odd numbers: not divisible by 2

    • Prime numbers: divisible only by 1 and itself

    • Composite numbers: have more than two factors

    • LCM (Least Common Multiple): smallest common multiple

    • HCF (Highest Common Factor): greatest common divisor

    🧩 Relationship:
    LCM × HCF = Product of two numbers

    🔹 4.2. Ratio and Proportion

    • Ratio: comparison of two quantities.
      a:b=ab

    • Proportion: equality of two ratios.
      ab=cd

    Example:
    If 2 pens cost ₹10, then 6 pens cost ₹30.

    🔹 4.3. Percentage

    Percentage=PartWhole×100

    • Increase/Decrease:
      New Value = Old Value × (1 ± Rate/100)

    Example: Price ₹100 increased by 10% = ₹110.

    🔹 4.4. Profit and Loss

    Profit=SP−CP,Loss=CP−SP
    %Profit=ProfitCP×100
    %Loss=LossCP×100

    🔹 4.5. Simple and Compound Interest

    • Simple Interest (SI):

      SI=P×R×T100

    • Compound Interest (CI):

      CI=P(1+R100)T−P

    Example: ₹1000 at 10% for 2 years
    → SI = 200; CI = 210.

    🔹 4.6. Average

    Average=Sum of itemsNumber of items

    Example:
    Marks in 5 subjects = 60, 70, 80, 90, 100
    Average = 400 ÷ 5 = 80

    🔹 4.7. Time and Work

    If A can do a work in x days → 1 day’s work = 1/x
    If B can do it in y days → 1 day’s work = 1/y

    Together:

    Time=xyx+y

    🔹 4.8. Speed, Distance, and Time

    Speed=DistanceTime,Time=DistanceSpeed

    If object travels at different speeds for equal distances:
    Average Speed = 2xyx+y

    🔹 4.9. Permutation and Combination (Basic)

    • Permutation: Arrangement → nPr=n!(n−r)!

    • Combination: Selection → nCr=n!r!(n−r)!

    Example:
    From 5 persons, select 2 → 5C2 = 10.

    🔹 4.10. Probability (Elementary)

    P(E)=Favorable outcomesTotal outcomes

    Example:
    A dice rolled → P(getting even number) = 3/6 = 1/2.

    📚 5. TIPS TO SOLVE QUESTIONS IN EXAM

    1. Read carefully – watch for “not”, “all”, “some”.

    2. Simplify logically – reduce long statements using truth rules.

    3. Make short tables for ratio, percentage, etc.

    4. Avoid lengthy calculations – use mental math and common fractions.

    5. Check for units (e.g., km/hr vs m/s).

    6. Eliminate impossible options in MCQs.

    7. Practise previous-year patterns – NET repeats logic types (syllogism, implication, numerical pattern).

    🧩 6. SHORTCUT MEMORY CHART

    Concept Formula / Logic Shortcut
    Profit % (SP–CP)/CP ×100 If gain 20%, SP = 1.2 × CP
    Compound Interest P(1+R/100)T–P Add interest each year successively
    Work (together) xyx+y
    		 Multiply divide rule
    % to Fraction 25% = 1/4, 20% = 1/5 Memorize key ones
    Ratio sum a:b = x:y → total = x+y To divide ₹120 in 2:3 → (2/5, 3/5) × 120
    Logical negation “All A are B” → “Some A are not B” Use opposite quantifier
    If p→q Contrapositive: ¬q → ¬p Always logically equivalent
