Where does the government's right to rule actually come from? Why should anyone obey a law? For thousands of years, the greatest thinkers — Aristotle, Hobbes, Locke, Montesquieu — wrestled with these questions, and their answers shaped the very structure of the Philippine government you live under. The Civil Service Exam tests these foundational ideas about power, legitimacy, and governance, along with the specific thinkers and their landmark books. This chapter organizes the ideas and pairs each thinker with their signature work, so the theory makes sense and the names stick.
Political-science theory questions test foundational ideas about power, legitimacy, and governance — plus a set of specific thinkers, their landmark books, and famous quotes. The main difficulty is pairing thinkers with their works correctly, since several wrote about overlapping themes.
On the Civil Service Exam, Political Science & Government Theory is a notable part of General Information — expect questions matching philosophers to their books and ideas (social contract, separation of powers), and defining core concepts (sovereignty, rule of law). They favor precise thinker-to-work pairing.
The difficulty is intermediate to advanced — the concepts connect to real government (the same logic behind the Philippine Constitution's three branches), but the thinker-to-book matching is precise and easily confused. The skill is understanding each idea and locking each thinker to their signature work. This lesson builds both.
After completing this lesson you will be able to:
You should be comfortable with:
A quick refresher on the study approach: like Sociology, this topic has a concept half (understand — social contract, sovereignty, rule of law) and a thinker half (memorize — who wrote what). For the thinker half, pair each philosopher with their one landmark book (Hobbes → Leviathan, Locke → Two Treatises). Keep this "concept vs. thinker" split in mind, and drill the book pairings like flashcards.
Understanding political theory illuminates government and citizenship:
The exam tests political theory because understanding the foundations of government is essential for a public servant and citizen.
Let's build from the thinkers to the core principles.
Lock each thinker to their landmark work:
Analogy: The social-contract thinkers are like people debating the rules of a shared household. Hobbes says "pick one strict landlord to keep order"; Locke says "we agree on rules together, and can replace a landlord who breaks them." Same problem (how to live together), different answers.
Developed across Hobbes, Locke, and Jean-Jacques Rousseau, social contract theory holds that governments derive legitimate authority from an implicit agreement among the governed — people give up some freedom for the protection and order a government provides. This underlies the modern principle that government power flows from the consent of the people, not divine right or force. The three differ in tone: Hobbes emphasized escaping a brutal state of nature through strong authority, while Locke and Rousseau emphasized preserving natural rights and popular sovereignty.
Associated with the French philosopher Montesquieu, this principle argues government power should be divided among separate branches (legislative, executive, judicial) to prevent any one from becoming too powerful — the same structural logic behind the Philippine Constitution's three branches.
Sovereignty is the supreme authority within a territory — the recognized right of a state to govern itself without external interference. In a democracy, sovereignty resides in the people, who exercise it through elections and constitutional processes.
The rule of law is the principle that all individuals and institutions, including the government itself, are subject to and accountable under the law — no one, including public officials, is above it. This is a core value throughout the Philippine Constitution, reinforced by laws like RA 6713 (the Code of Conduct for public officials).
From roughly 1453 (the fall of Constantinople, marking the end of the medieval era) through the end of the 17th century, the Renaissance revived classical learning and humanist thought, placing growing emphasis on human reason alongside or above religious dogma as a basis for understanding government — a defining tension of the transition into the modern political era.
With the thinkers and principles laid out, let's picture, tabulate, and drill.
| Thinker | Work / Idea |
|---|---|
| Aristotle | Politics; "man is a political animal" |
| Plato | Republic; justice as harmony |
| Hobbes | Leviathan (1651); strong authority |
| Locke | Two Treatises (1689); consent of the governed |
| Mill | On Liberty (1859) |
| Rawls | A Theory of Justice (1971) |
| T.H. Green | rights = conditions to be one's best self |
| Harold Laski | A Grammar of Politics (1925) |
| Montesquieu | separation of powers |
| Social contract | Hobbes, Locke, Rousseau |
| Sovereignty | supreme authority (people in a democracy) |
| Rule of law | all, including government, under the law |
| Democracy origin | Ancient Athens |
| When the question mentions… | Recall… |
|---|---|
| "man is a political animal" | Aristotle (Politics) |
| Leviathan, strong authority | Hobbes |
| consent of the governed | Locke (Two Treatises) |
| separation of powers | Montesquieu |
| supreme authority in a territory | sovereignty |
| government also under the law | rule of law |
| origins of democracy | Ancient Athens |
| fairness, distributive justice | Rawls (A Theory of Justice) |
| institutions vs. data-driven study | traditional vs. behavioral approach |
Step 1 — Decide if it's a thinker or a concept question. ↓ Step 2 — For thinkers, recall the book/quote pairing. ↓ Step 3 — For concepts, recall the definition (sovereignty, rule of law, social contract). ↓ Step 4 — Watch the confusion traps (Hobbes vs. Locke, Aristotle vs. Plato, Green vs. Laski, separation of powers → Montesquieu). ↓ Step 5 — Eliminate pairings or definitions that belong to a different thinker or concept.
Why Step 2 matters most: the thinker-to-work pairing is where difficulty concentrates. Several philosophers wrote on overlapping themes (social contract, rights), so locking each to their specific book is the decisive skill.
Example 1. Who wrote "Man is a political animal," and in what work? Solution: Aristotle, in Politics. Difficulty: ★☆☆☆☆
Example 2. Where did democracy originate? Solution: Ancient Greece (Athens). Difficulty: ★☆☆☆☆
Example 3. Who wrote Leviathan, and what does its social contract argue? Solution: Thomas Hobbes — people surrender freedoms to an absolute authority for order and protection. Difficulty: ★★☆☆☆
Example 4. Who is associated with the separation of powers? Solution: Montesquieu. Difficulty: ★★☆☆☆
Example 5. What is sovereignty? Solution: The supreme authority within a territory — the right to govern without external interference (residing in the people in a democracy). Difficulty: ★★★☆☆
Example 6. How do Hobbes and Locke differ, though both are social contract theorists? Solution: Hobbes (Leviathan) favors a strong central authority; Locke (Two Treatises) favors natural rights and limited government by consent, with a right to overthrow a failing government. Difficulty: ★★★☆☆
Example 7. What does the "rule of law" mean, and does it apply to the government? Solution: All individuals and institutions, including the government, are subject to and accountable under the law — no one is above it. Difficulty: ★★★☆☆
Example 8. Who wrote A Theory of Justice, and what is its focus? Solution: John Rawls (1971); fairness and distributive justice. Difficulty: ★★★☆☆
Example 9. Distinguish T.H. Green's and Harold Laski's definitions of rights. Solution: Green: rights are "conditions of social life without which no man can be his best self." Laski: a right is "a claim recognized by society and enforced by the state." Difficulty: ★★★★☆
Example 10. What is the difference between the traditional and behavioral approaches to political science? Solution: Traditional emphasizes formal institutions, legal structures, history, and philosophy; behavioral is empirical and data-driven. Difficulty: ★★★★☆
Example 11. Which three thinkers are central to social contract theory? Solution: Hobbes, Locke, and Rousseau. Difficulty: ★★★☆☆
Example 12. Who wrote the Republic, and who wrote Politics? Solution: Plato wrote the Republic; Aristotle (Plato's student) wrote Politics. Difficulty: ★★★★☆
Political science theory explores power, legitimacy, and governance. Master the thinkers and their works: Aristotle (Politics, "political animal"), Plato (Republic), Hobbes (Leviathan, strong authority), Locke (Two Treatises, consent of the governed), Mill (On Liberty), Rawls (A Theory of Justice), plus Green and Laski on rights. Understand the concepts: social contract (Hobbes, Locke, Rousseau — government by agreement), separation of powers (Montesquieu), sovereignty (supreme authority, residing in the people), and the rule of law (all, including government, under the law). Keep the confusable pairs distinct (Hobbes/Locke, Aristotle/Plato, Green/Laski), attribute separation of powers to Montesquieu, and connect these ideas to the Philippine Constitution. Lock the pairings and definitions, and this becomes a dependable, high-yield strength.

Who is associated with the separation of powers? Montesquieu, the French philosopher. He argued government power should be divided among legislative, executive, and judicial branches — the same logic behind the Philippine Constitution's three branches. It's not Locke, Hobbes, or Rousseau.
How do Hobbes and Locke differ? Both are social contract theorists, but Hobbes (Leviathan) favors surrendering freedoms to a strong absolute authority for order, while Locke (Two Treatises) favors natural rights, limited government by consent, and a right to overthrow a failing government.
What is the difference between sovereignty and the social contract? They answer different questions. The social contract explains why government has legitimate authority (an agreement among the governed). Sovereignty is who holds supreme authority — in a democracy, the people.
Does the rule of law apply to the government? Yes. The rule of law means everyone, including public officials and the government itself, is subject to and accountable under the law — no one is above it.
Who wrote Politics and who wrote the Republic? Aristotle wrote Politics; his teacher Plato wrote the Republic. Both are foundational, but they are different books by different authors — a common trap.
Tick them all and Political Science becomes a dependable, high-yield strength — and you'll understand the ideas that built the government you serve.
