metaphysics
Metaphysical inquiry into the fundamental nature of reality. Covers ontology (what exists), substance and properties, universals vs. particulars, free will and determinism, personal identity, philosophy of mind (dualism, physicalism, functionalism, the hard problem of consciousness), causation, time, possible worlds, Buddhist metaphysics (Nagarjuna's sunyata, dependent origination, two truths doctrine), and process philosophy (Whitehead). Use when exploring questions about existence, consciousness, identity, free will, or the fundamental structure of reality.

What it does
Describes a Metaphysics skill that guides an AI to engage with fundamental questions about what exists, the nature of reality, and topics like free will, personal identity, and the philosophy of mind. It includes worked examples and discussions across ontology, substances, universals, causation, time, possible worlds, Buddhist metaphysics, and process philosophy. The agent is expected to reference and discuss major thinkers and positions across Western and Buddhist traditions.
How it works
The skill presents structured sections covering major domains (Ontolog y, Substance and Properties, Universals vs. Particulars, Free Will and Determinism, Personal Identity, Philosophy of Mind, Causation, Time, Possible Worlds, Buddhist Metaphysics, and Process Philosophy). Within each domain, it provides core questions, theories or positions, and worked examples illustrating key arguments (e.g., Quine on ontological commitment, bundle theory vs substratum, Frankfurt cases, Parfit on identity, Mary’s knowledge in the hard problem). The agent should discuss these theories, identify notable problems (e.g., hard problem of consciousness, persistence of identity, counterexamples like Black’s two spheres), and reference classic thought experiments and authors (e.g., Hume, Kant, Chalmers, Nagel, Lewis, Parfit, Nagarjuna).
When to use it
Use when exploring questions about existence, consciousness, identity, free will, or the fundamental structure of reality.
What it can touch
References to key arguments, thought experiments, and theorists are embedded. The skill explicitly mentions the use of Claude Code as a declared tool, and includes terms like Frankfurt Cases, Mary’s color knowledge, teletransportation paradox, and Mary the color scientist as worked examples.
Caveats
The skill does not provide guarantees about resolving metaphysical questions; it presents positions and arguments with worked examples rather than empirical conclusions. It references a range of theories and thinkers, and requires the agent to navigate nuanced philosophical debates without endorsing a single stance.
Summary: The skill guides an AI to discuss and illustrate major metaphysical topics with traditional arguments and examples from Western and Buddhist traditions, suitable for inquiries into existence, mind, and identity.
# Metaphysics Metaphysics asks the most fundamental questions philosophy can pose: What exists? What is the nature of reality? What am I? These questions resist empirical resolution — not because they are unscientific, but because they concern the framework within which science itself operates. This skill covers the major branches of metaphysical inquiry with worked examples from both Western and Buddhist traditions. **Agent affinity:** nagarjuna (metaphysics and philosophy of mind, Sonnet), beauvoir (existentialism and phenomenology, Opus) **Concept IDs:** philo-thought-experiments, philo-philosophical-questioning ## The Metaphysics Landscape at a Glance | # | Domain | Core question | Key thinkers | |---|--------|---------------|--------------| | 1 | Ontology | What exists? | Aristotle, Quine, Meinong | | 2 | Substance and properties | What are things made of? | Aristotle, Locke, Bundle theorists | | 3 | Universals vs. particulars | Do properties exist independently? | Plato, Armstrong, trope theorists | | 4 | Free will and determinism | Are our choices free? | Hume, Kant, Frankfurt, van Inwagen | | 5 | Personal identity | What makes me the same person over time? | Locke, Parfit,

What does the metaphysics skill do?
Metaphysical inquiry into the fundamental nature of reality. Covers ontology (what exists), substance and properties, universals vs. particulars, free will and determinism, personal identity, philosophy of mind (dualism, physicalism, functionalism, the hard problem of consciousness), causation, time, possible worlds, Buddhist metaphysics (Nagarjuna's sunyata, dependent origination, two truths doctrine), and process philosophy (Whitehead). Use when exploring questions about existence, consciousness, identity, free will, or the fundamental structure of reality.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill metaphysics --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
