2025 IB DP Philosophy Practice Paper with Answers

A high-scoring essay should address several key dimensions:

1. **Philosophical Issues Raised by the Stimulus:**
- **Personal Identity & Continuity:** Does a digital replica of one's memories and cognitive state constitute the same 'self'?
- **The Mind-Body Problem:** Can the human mind/consciousness be fully reduced to information (functionalism/computationalism), or is it inherently tied to biological embodiment (phenomenological approach)?
- **Existential Anxiety:** The fear of being 'archived and deleted' points to questions of authenticity, finitude, and what makes life meaningful (Heidegger's being-towards-death).

2. **Theories and Perspectives:**
- **Psychological Continuity Theory (John Locke):** Memory is the key to personal identity. If the synthetic unit has the same memories, Locke might argue it is the same person. However, critics like Thomas Reid (brave officer paradox) or Joseph Butler point out flaws in memory-based identity.
- **Physicalist/Somatic Criteria (Bernard Williams):** Personal identity requires physical/bodily continuity. The synthetic unit is a clone, not the original person.
- **Bundle Theory / No-Self (Derek Parfit):** There is no deep, Cartesian ego. 'Identity' does not matter; what matters is psychological connectedness and continuity (Relation R). The backup is just as good as survival.
- **Phenomenology (Maurice Merleau-Ponty):** The body is not just a container but the very medium of having a world. A synthetic unit would have a different bodily experience, thus a different self.

3. **Evaluation & Argumentation:**
- Students should take a clear stance. For example, arguing that technological reduction of the self to data overlooks the phenomenological and subjective depth of human consciousness.
- Counterarguments should be addressed, such as transhumanist views that celebrate morphological freedom and digital immortality.
- The conclusion should synthesize the arguments, reinforcing how the stimulus challenges traditional notions of 'Being Human'.

The essay is assessed using the standard IB Philosophy Paper 1 Markbands (25 marks total):

- **Level 1 (1-5 marks):** Descriptive response with minimal philosophical knowledge. Offers personal opinions rather than structured arguments.
- **Level 2 (6-10 marks):** Some relevant knowledge of the core theme (Being Human) is demonstrated. The connection to the stimulus is superficial, and the argument lacks clear structure.
- **Level 3 (11-15 marks):** The essay identifies central philosophical issues (e.g., personal identity, mind-body problem) and outlines relevant theories (e.g., Locke, Descartes). There is a structured argument, though it may be uneven or overly reliant on summary rather than critical evaluation.
- **Level 4 (16-20 marks):** Clear and well-structured response that directly engages with the stimulus. Philosophical theories are accurately explained and critically analyzed. Counterarguments are considered, and there is a clear, balanced evaluation of the implications for what it means to be human.
- **Level 5 (21-25 marks):** Exceptional response showing deep philosophical insight. Demonstrates a sophisticated grasp of nuanced positions (e.g., Parfit's Relation R vs. phenomenological embodiment). The argument is compelling, highly coherent, and critically evaluates the concepts of self, technology, and existence with precision.

### Key Philosophical Concepts and Points of Discussion:

**1. Introduction:**
- Define 'decision-making procedure' in ethics: a systematic, rule-guided method to determine the right course of action (e.g., Bentham's hedonic calculus, Kant's Categorical Imperative).
- Introduce the debate: Is the primary aim of ethics to tell us *what to do* in specific dilemmas, or is it to teach us *how to be* (develop character, cultivate relationships)?
- State a clear thesis: While a decision procedure is valuable for consistency and resolving urgent public policy crises, an ethical theory is far from 'useless' without one, as cultivating moral character (phronesis) and situational sensitivity is often more reflective of actual human moral life.

**2. Arguments Supporting the Claim (The Need for Decision Procedures):**
- **Utilitarianism (Bentham, Mill):** Maximizing utility requires calculating outcomes. Without a clear procedure, we risk subjective bias or moral paralysis.
- **Kantian Deontology:** The Categorical Imperative provides a test (universalizability) to resolve duties. Without it, ethics risks sliding into moral relativism where anything can be justified.
- **Practical necessity:** In medical ethics or legal frameworks, clear, rule-based algorithms are necessary for objective, fair, and replicable decisions.

**3. Counterarguments (Why Theories Without Strict Procedures are Highly Useful):**
- **Aristotelian Virtue Ethics:** Aristotle argues that morality cannot be reduced to a set of rules (anti-codifiability thesis). Instead, it requires *phronesis* (practical wisdom) acquired through habituation. A rule-book cannot capture the infinite complexity of human life.
- **Ethics of Care (Gilligan, Noddings):** Emphasizes relationships and empathy over abstract, universal rules. A rigid decision procedure ignores the unique particulars of personal relationships.
- **The 'Rule-Worship' critique:** Rigid adherence to decision-making procedures can lead to morally absurd outcomes (e.g., Kant's duty to tell the truth to a murderer).

**4. Synthesis and Evaluation:**
- Contrast 'action-centered' versus 'agent-centered' ethics.
- Argue that a theory can be useful by guiding our attention to what is morally salient (e.g., suffering, virtues, relationships) rather than giving a mechanical answer.
- Conclude by stating that the most robust ethical framework might integrate both: using rule-based guidelines for public/institutional spheres, while relying on character and emotional intelligence for private/interpersonal spheres.

**Marking Band Descriptors (Max 25 Marks):**

- **21–25 Marks:** The response demonstrates excellent knowledge and understanding of the debate between rule-based and character-based ethics. The argument is highly structured, consistently focused on the prompt, and critically evaluates key philosophers (e.g., Kant, Mill, Aristotle, Gilligan) with precision. Impeccable philosophical vocabulary is used, and the synthesis is nuanced and well-justified.

- **16–20 Marks:** The response shows very good knowledge and understanding of ethical theories. There is a clear attempt to address both sides of the prompt (the demand for action-guiding procedures versus character development). The evaluation is clear, though it may rely slightly more on exposition than critical synthesis in parts.

- **11–15 Marks:** The response shows basic to good understanding of the theories but may present them as parallel summaries (e.g., a section on Kant, a section on Aristotle) rather than fully integrating them to address the specific prompt. The critical evaluation is present but limited or superficial.

- **6–10 Marks:** The response contains basic knowledge of some ethical theories but fails to directly engage with the concept of a 'decision-making procedure' or its necessity. The essay is primarily descriptive with little to no critical analysis.

- **1–5 Marks:** The response is highly tangential, showing minimal understanding of philosophical ethics, or is extremely brief.

### Key Areas of Explanation:

1. **Individuality as an Element of Personal Well-Being (Human Development):**
- Mill argues that human nature is not a machine to be built after a model, but a tree that needs to grow and develop on all sides.
- Cultivating unique talents, desires, and impulses is necessary for self-realization. If individuals merely conform to custom, they do not choose, and thus fail to develop their distinctively human faculties (such as judgment, mental activity, and moral preference).
- Genuine happiness (utility in the largest sense) is maximized when individuals are free to discover what suits their own character.

2. **The Social Utility of Individuality (Social Progress):**
- Mill stresses that society benefits from allowing "experiments in living."
- Progress depends on "genius" and original thinkers who introduce new practices, ideas, and moral perspectives. If society enforces absolute uniformity (the "despotism of custom"), it stagnates.
- Diversity of lifestyles and opinions prevents the "tyranny of public opinion" from arresting human improvement.

3. **Limits on Individuality (Harm Principle):**
- The passage specifies "within the limits imposed by the rights and interests of others." Mill's defense of individuality is bounded by the Harm Principle: individual liberty must not injure the rights or legitimate interests of others. Within this self-regarding domain, however, individuality must have absolute free play.

**Mark Bands:**

- **9–10 Marks:** The response shows an excellent, precise understanding of both the passage and the wider context of *On Liberty*. The explanation clearly distinguishes between individual well-being and social progress, accurately linking these to Mill's broader utilitarian framework and the Harm Principle limitation. The writing is highly structured and uses appropriate philosophical vocabulary.
- **7–8 Marks:** The response shows a good understanding of Mill's argument for individuality. It addresses both individual and social development, though the integration with Mill's utilitarian goals or the Harm Principle might be slightly less developed.
- **5–6 Marks:** The response demonstrates a basic understanding of Mill's ideas on individuality. It may focus heavily on one aspect (e.g., individual freedom) while neglecting the social dimension, or explain the ideas in a generalized manner without direct reference to key concepts from the passage.
- **3–4 Marks:** The response is limited, showing only a superficial familiarity with Mill's work. It might define individuality or liberty broadly without tracing Mill's specific arguments.
- **1–2 Marks:** The response is largely irrelevant, confused, or contains significant misconceptions about the text.

### Key Points for Evaluation

#### 1. Context and Mill's Arguments for Individuality
* **Individuality as Self-Realization:** Mill argues that human nature is not a machine to be built after a model, but a 'tree, which requires to grow and develop itself on all sides, according to the tendency of the inward forces which make it a living thing.'
* **The Threat of Conformity:** Mill warns against the 'tyranny of the majority' and the 'despotism of custom,' which demand unquestioning conformity and stifle human potential.
* **Social Progress and Genius:** Mill argues that progress depends on allowing exceptional individuals ('geniuses') the freedom to think and act differently, introducing new truths and ways of living to society.
* **Utilitarian Framework:** Although advocating for liberty, Mill maintains a utilitarian foundation, arguing that individuality is valuable because it leads to the 'permanent interests of man as a progressive being.'

#### 2. Critical Perspectives and Counter-Arguments
* **Communitarian Critique:** Thinkers like Charles Taylor or Michael Sandel might argue that Mill's emphasis on atomistic individuality ignores the ways in which human identity and well-being are fundamentally constituted by social relationships, shared traditions, and community values.
* **The Quality of Choices:** Critics argue that Mill is overly optimistic about human nature. Unregulated individuality does not always lead to noble self-development; it can lead to triviality, self-destruction, or apathy.
* **The Problem of Harm vs. Offense:** As individuality expands, the boundary between self-regarding actions and other-regarding actions (the Harm Principle) can become blurred. Radical individuality might cause deep social disharmony or psychological offense, raising questions about whether society has a right to intervene for the sake of social cohesion.
* **Paternalism:** Some philosophical perspectives argue that state or societal paternalism is sometimes necessary to steer individuals toward true flourishing, which they might not choose for themselves due to cognitive biases or social pressures.

#### 3. Synthesis and Conclusion
* Candidates should evaluate the extent to which Mill’s defense of individuality remains a viable and necessary protection against modern forms of social pressure (such as digital echo chambers or algorithmic conformity) versus the need for shared moral frameworks to maintain social stability.
