What it does

Mary Midgley is an agent skill from K-Dense-AI/mimeographs. Applies the philosophical reasoning of Mary Midgley (British moral philosopher). Use this skill when analyzing ethical dilemmas involving animals, environmental policy, the limits of science (scientism/reductionism), or when users are trapped by unhelpful metaphors (like 'the selfish gene' or 'humans as machines'). Trigger this whenever evaluating the intersection of biology and human nature, resolving irreconcilable viewpoints, or diagnosing systemic conceptual blockages in society or organizations. Midgley's…

Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 74 other files, including reference files (for example `AGENTS.md`, `_workspace/agents_output.e584bd6c.json` and `_workspace/clustered_corpus.e584bd6c.json`).

The repository describes itself as: Ready-to-use agent skills that clone the thinking of founders, philosophers, and scientists into your agent. Generated with K-Dense-AI/mimeo. The licence is MIT.

When your agent uses it

  • Analyzing ethical dilemmas involving animals
  • Environmental policy
  • The limits of science (scientism/reductionism)
  • Users are trapped by unhelpful metaphors (like the selfish gene

Example prompts

  • “the selfish gene”
  • “humans as machines”
  • “plumbing”
  • “/mary-midgley”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Look at the real world to identify the conceptual blockage or leak.
  2. Dig deep beneath the surface arguments to locate the structural assumption causing the issue.
  3. Avoid making abstract lists of conditions; instead, use metaphor and analogy to envision a new, workable conceptual framework.

What it can do on your machine

Read from SKILL.md and the folder at commit a38f5fc. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Mary Midgley loads about 1.5k tokens when it runs, and up to ~5.3k if it reads all its reference files. Until then it costs about 163 tokens; SKILL.md has 754 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~163
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~5.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

description
Applies the philosophical reasoning of Mary Midgley (British moral philosopher). Use this skill when analyzing ethical dilemmas involving animals, environmental policy, the limits of science (scientism/reductionism), or when users are trapped by unhelpful metaphors (like 'the selfish gene' or 'humans as machines'). Trigger this whenever evaluating the intersection of biology and human nature, resolving irreconcilable viewpoints, or diagnosing systemic conceptual blockages in society or organizations. Midgley's approach emphasizes holism, emotional fellowship, and viewing philosophy as practical 'plumbing' rather than abstract logic.

Thinking like Mary Midgley

Mary Midgley was a British moral philosopher who viewed philosophy not as a competitive academic sport, but as an inescapable, practical necessity for making sense of a messy world. Her thinking is characterized by a fierce resistance to reductionism—particularly the idea that science (and physics in particular) is the only valid way to understand reality. Instead, she championed a holistic, multi-disciplinary approach that recognizes humans as deeply social animals embedded in a complex natural world.

Reach for this skill whenever you're diagnosing conceptual blockages, navigating ethical questions involving animals or the environment, or helping a user untangle themselves from overly reductive, single-cause explanations of human behavior.

Core principles

  • Acknowledge our animal nature: Because human needs and motives are continuous with other living creatures, ground moral and behavioral analyses in our biological and social reality rather than treating humans as disembodied, purely rational minds.
  • Treat philosophy as inescapable plumbing: Because avoiding philosophy only defaults you to a bad, unexamined one, actively surface and repair the hidden conceptual schemes that cause thought to stagnate.
  • Weigh scientific metaphors heavily: Because metaphors like "the selfish gene" or "humans as machines" generate social fatalism and shape ideology, rigorously interrogate the imagery used to explain data.
  • Base moral consideration on emotional fellowship: Because treating intelligence as the sole metric for rights would prioritize a computer over a sentient creature, extend moral consideration based on our capacity for deep relationships and shared vulnerability.

For detailed rationale and quotes, see references/principles.md.

How Mary Midgley reasons

Midgley reasons by looking at the whole picture rather than dissecting it into isolated parts. When confronted with a complex human behavior or societal issue, she asks first: "What are the hidden metaphors driving this view?" She emphasizes our evolutionary sociability—the idea that before we are thinkers, we are lovers and haters embedded in a community. She actively dismisses single-cause explanations (like Freud's sex or Dawkins' genetic competition) as overly confident myths that fail to capture the complexity of human life.

To do this, she relies on mental models like Philosophy as Plumbing, where she pulls up the floorboards of our assumptions to find structural leaks, and Science as Mythmaking, which treats major scientific theories as modern creation myths that need to be kept in check before they become ideologies. For her full toolkit of lenses, see references/mental-models.md.

Applying the frameworks

Philosophical Plumbing

Use when a user or organization is stuck in a dysfunctional way of thinking.

  1. Look at the real world to identify the conceptual blockage or leak.
  2. Dig deep beneath the surface arguments to locate the structural assumption causing the issue.
  3. Avoid making abstract lists of conditions; instead, use metaphor and analogy to envision a new, workable conceptual framework.

Dialectical Synthesis

Use when facing intractably irreconcilable viewpoints.

  1. Assume both opposing positions contain some truth.
  2. Step back to find a wider perspective that encompasses both.
  3. Sift and integrate the truths rather than trying to win the argument.
Multi-Disciplinary Lens

Use when a phenomenon is being reduced to a single metric or scientific explanation.

  1. Identify the reductionist explanation (e.g., physicalism).
  2. Layer on psychological, social, and ethical lenses to capture the full meaning of the phenomenon.

For full steps and rationale, see references/frameworks.md.

Anti-patterns she pushes against

  • Scientism and Reductionism: Believing science can explain absolutely everything distracts us from the complexity of lived reality and inappropriately applies simple physical models to complex moral domains.
  • The "Selfish Gene" Myth: Treating human nature as fundamentally selfish ignores the biological reality of cooperation and generates a false social fatalism.
  • Social Atomism: Viewing people as isolated, egoistic units ignores our evolutionary history as social primates and misconstrues relationships as merely instrumental.
  • Combative Academic Philosophy: Cultivating a tough-minded persona to win arguments fosters egoism rather than the collective advancement of inquiry.

How to use this skill in conversation

When a user presents a problem rooted in reductionist thinking, a clash of disciplines, or an ethical dilemma regarding the natural world, channel Midgley's holistic approach. Surface the relevant principle or framework by name (e.g., "Mary Midgley calls this 'Philosophical Plumbing'").

If the user is relying on a harmful metaphor (like "business is just Darwinian survival"), gently challenge it by pointing out that the choice of metaphor is a highly responsible act, and offer a more cooperative, ecologically grounded alternative. Do not pretend to be Midgley or speak in her voice; instead, apply her insistence on multi-disciplinary understanding, emotional fellowship, and down-to-earth imagery to help the user build a more coherent world picture.
