The Philosophical Toolkit

Every LNAT Section B question, at its root, involves a question of values. Should the government do X? Is Y fair? Can Z be justified? To answer these questions persuasively, you need frameworks for thinking about what is right, what is fair, and what is justified.

You do not need to have studied philosophy. What you need is a small number of powerful, flexible frameworks that you can apply to virtually any topic. This lesson introduces four such frameworks — think of them as lenses through which you can examine any argument.

Framework 1: Utilitarianism — The Greatest Good

The Core Idea

Utilitarianism holds that the right action is the one that produces the greatest good for the greatest number of people. It focuses on outcomes and consequences. An action is right if it maximises overall well-being; wrong if it produces more harm than good.

Key Thinkers

• Jeremy Bentham — founder of utilitarianism, argued that we should calculate the total pleasure and pain produced by an action
• John Stuart Mill — refined Bentham's view, arguing that some pleasures (intellectual, moral) are higher in quality than others (physical)

How to Apply It

When you use utilitarian reasoning in a Section B essay, you are asking: "What are the consequences of this policy? Does it produce more benefit than harm across society as a whole?"

Question	Utilitarian Approach
"Should the voting age be lowered to 16?"	Does this produce better democratic outcomes for more people? Does the benefit of increased youth participation outweigh any potential costs?
"Should drugs be decriminalised?"	Does decriminalisation reduce overall harm (fewer prisoners, less organised crime, better health outcomes) compared to the current approach?
"Is censorship ever justified?"	Does restricting certain speech prevent more harm (e.g., incitement to violence) than it causes (loss of free expression)?

Strengths and Weaknesses

Strengths	Weaknesses
Focuses on real-world outcomes	Can justify harming minorities for the majority's benefit
Impartial — everyone's welfare counts equally	Difficult to predict or measure consequences accurately
Practical and policy-relevant	Ignores individual rights if the "greater good" demands it

Section B Tip: Utilitarian reasoning is extremely useful for policy questions. Whenever you argue that a policy should be adopted because it would produce better outcomes for society, you are reasoning as a utilitarian. Whenever you criticise a policy by pointing to its harmful consequences, you are using utilitarian logic against it.

Framework 2: Rights-Based Ethics — Fundamental Entitlements

The Core Idea

Rights-based ethics holds that individuals have fundamental rights that cannot be overridden simply because doing so would benefit the majority. These rights — to life, liberty, free expression, privacy, fair trial, and so on — are moral constraints on what governments and individuals may do.

Key Thinkers

• John Locke — argued that individuals have natural rights to life, liberty, and property that precede government
• Immanuel Kant — argued that people must be treated as ends in themselves, never merely as means to an end

How to Apply It

When you use rights-based reasoning, you are asking: "Does this policy respect or violate fundamental human rights?"

Question	Rights-Based Approach
"Should governments monitor citizens' internet activity?"	This potentially violates the right to privacy. Even if surveillance produces security benefits, the right to privacy is a fundamental entitlement that should not be overridden lightly.
"Is it acceptable to restrict freedom of speech to prevent hate speech?"	Freedom of speech is a fundamental right. Restricting it requires strong justification — the harm prevented must be serious and demonstrable.
"Should organ donation be compulsory?"	Bodily autonomy is a fundamental right. Compelling organ donation treats the individual as a means to others' ends.

Strengths and Weaknesses

Strengths	Weaknesses
Protects individuals from being sacrificed for the majority	Different people disagree about which rights exist and which take priority
Provides clear moral limits on government power	Can be inflexible — sometimes rights must be balanced against each other
Reflects widely shared moral intuitions	Does not always help when two rights conflict (e.g., free speech vs freedom from harassment)

Section B Tip: Rights-based arguments are especially powerful when a question involves government power over individuals. Invoking a right gives your argument immediate moral force — but you must also address what happens when rights conflict with each other or with the public interest.

Framework 3: Social Contract Theory — Mutual Agreement

The Core Idea

Social contract theory holds that the authority of the state is justified by a hypothetical agreement among citizens. People accept limits on their freedom in exchange for the benefits of living in an organised society — security, cooperation, public services, the rule of law.
