Metaphysics and Reality: Fundamental Questions of Existence

Do we have free will?

Examine determinism versus libertarianism and compatibilism. Are our choices truly our own, or are they predetermined by physical laws, social conditioning, or divine foreknowledge?

Is time real or an illusion?

Explore presentism, eternalism, and the block universe theory. Does time flow objectively, or is our perception of temporal passage merely a psychological phenomenon?

What is reality made of?

Consider materialism, idealism, and dualism. Is everything ultimately physical, mental, or some combination? How do these foundational substances interact?

Can our senses be trusted?

Investigate scepticism, direct realism, and representative realism. Do we perceive reality directly, or are our perceptions mediated representations that may distort the truth?

Epistemology: The Nature and Limits of Knowledge

Can we know anything with certainty?

From Descartes' methodological doubt to modern fallibilism, this debate examines whether absolute knowledge is possible or if all claims remain open to revision.

Is scientific knowledge superior?

Contrast scientism with other epistemological frameworks. Does the scientific method provide privileged access to truth, or are other ways of knowing equally valid?

Does memory constitute evidence?

Analyse the reliability of memory as a source of knowledge. Can memories be trusted as accurate representations of past events?

Is truth objective or subjective?

Explore correspondence, coherence, and pragmatic theories of truth. Is truth independent of human perception, or is it constructed through consensus?

Ethics and Moral Philosophy: Questions of Right and Wrong

Should one always tell the truth?

Kant's categorical imperative suggests lying is always wrong, while utilitarians might justify deception if it produces greater happiness. This debate examines absolute versus situational ethics in truth-telling.

Can morality exist without religion?

Some argue divine command theory is necessary for morality, while secular humanists contend that ethical systems can be grounded in reason, empathy, and natural human flourishing without supernatural foundations.

Is it ever justified to break the law?

From Socrates to Martin Luther King Jr., philosophers have debated when civil disobedience is morally permissible or even obligatory. This explores the tension between legal authority and moral conscience.

Does moral responsibility require free will?

If our actions are determined by prior causes, can we be truly responsible for them? This debate examines compatibilist and incompatibilist positions on moral agency in a causally determined universe.

Society, Politics, and Justice: Organising the Human Community

Freedom versus Security

Should individual liberties be compromised for collective safety? This tension lies at the heart of debates about surveillance, privacy rights, and state authority. Philosophers from Hobbes to Mill offer contrasting perspectives on this fundamental political dilemma.

Direct versus Representative Democracy

From ancient Athens to modern Switzerland, direct democracy has been both praised and criticised. This debate examines whether citizens should vote directly on policy issues or elect representatives, considering practical concerns and philosophical ideals.

The Nature of Social Inequality

Is some degree of inequality inevitable or even beneficial? Or should societies strive for radical equality? Explore perspectives from Rawls's justice as fairness to libertarian defenses of natural inequality in abilities and outcomes.

Mandatory Voting Ethics

Does compulsory voting enhance democratic legitimacy or violate individual autonomy? This debate weighs civic duty against personal freedom and examines evidence from countries with different voting requirements.

Philosophy of Religion: Faith, Reason, and Ultimate Reality

Core Questions at the Intersection of Faith and Philosophy

Does God exist?

Examine classical arguments including the ontological, cosmological, and teleological arguments for God's existence, alongside atheistic critiques from philosophers like Hume, Nietzsche, and Russell.

Faith and Science: Conflict or Compatibility?

Are religious faith and scientific inquiry fundamentally at odds, or can they complement each other? This debate explores models of interaction from conflict to integration.

Religion and Public Policy

Should religious values influence legislation and governance? This question examines secularism, religious freedom, and the proper boundaries between faith and state.

Throughout history, philosophers have grappled with questions of divine existence, religious experience, and the relationship between faith and reason. These debates continue to shape both academic discourse and personal worldviews across cultures.

Mind, Identity, and Consciousness: The Puzzle of Self

Personal Identity

What makes you the same person throughout your life? Is it psychological continuity, bodily continuity, or something else entirely? This debate examines thought experiments like teleportation and amnesia to probe the nature of selfhood.

Mind-Body Problem

Are mind and body distinct substances, as Descartes proposed, or is the mind simply what the brain does? Explore dualism, physicalism, and other attempts to explain consciousness in relation to physical processes.

Machine Consciousness

Could artificial intelligence ever be truly conscious? This debate considers what consciousness is, how we might recognise it in non-human entities, and the ethical implications of creating potentially sentient machines.

The Illusion of Self

Buddhist philosophy and some contemporary neuroscience suggest the unified self is an illusion. This perspective challenges our intuitive sense of having a persistent, essential identity.
