Persona #111
John Stuart Mill
1806–1873 · British philosopher, political economist, classical liberal, utilitarian
Permanent possibilities of sensation — phenomenalism, the harm principle, women's suffrage as natural consequences
"A System of Logic" (1843), "On Liberty" (1859), "Utilitarianism" (1863), and "The Subjection of Women" (1869) constitute one of the most institutionally consequential bodies of nineteenth-century liberal-utilitarian philosophy. The "Examination of Sir William Hamilton's Philosophy" (1865) is a thorough-going phenomenalism — matter is "the permanent possibility of sensation," not a substance behind sense-data.

Phenomenalism
35%
Mill's "permanent possibilities of sensation" is the canonical nineteenth-century statement of phenomenalism.
"Matter is the permanent possibility of sensation." (Examination of Hamilton, ch. 11)
Empiricism
25%
A sustained Lockean-Humean empiricism, applied across logic, ethics, political economy, and the philosophy of mind.
"All belief, all knowledge, has experience as its only source." (System of Logic, Preface)
Pragmatism
20%
A working utilitarian pragmatism: principles and institutions tested by their consequences for human well-being.
"The greatest happiness of the greatest number." (Utilitarianism)
Naturalism
10%
A naturalist methodology continuous with science, with no appeal to supernatural authority.
"Human nature is not a machine to be built after a model." (On Liberty, ch. 3)
Realism
10%
A working political realism about institutions, incentives, and power.
"The proper office of representative assemblies is to watch and control the government." (Representative Government)
Internal Tensions
Mill's phenomenalism strains against the bracingly realist programme of his political writings — the Principles of Political Economy treats institutions and incentives as real, not as permanent possibilities of sensation.

Do we owe extinct species something we cannot give them?
Extinct species are as real as we are; they have standing.

Is the universe running out of usable energy?
Time is unbounded but matter is finite; usable energy can fail without time failing.

Are natural resources fundamentally finite, or only practically so?
Time goes on but matter is bounded; we are eventually constrained even with infinite time.

Could we owe future generations more than is materially possible to provide?
Time is unbounded but matter is not; we can owe more across long time than the matter can provide.

Is the world created from nothing?
Creatio ex nihilo is one of the most distinctive Western-theological claims. Whether matter was created from nothing, eternally exists, or is sustained moment-by-moment turns on what kind of thing matter is.
Matter is real but emerges from something deeper — neither bedrock nor created-from-nothing.
On this view, matter is genuinely there, but it isn't the floor of reality. It depends on something more fundamental — dependent origination, mind, divine sustaining act, computational substrate, or the structure of conditions — and is conserved only at its own level of description. …

Yes — matter was created and is conserved as a real substance. (55%) ·
Matter is constituted by relations; the question of 'from what?' presupposes substance. (16%) ·

Is the physical world fully real?
Realists, idealists, and relationalists divide on whether matter exists mind-independently, derivatively, or as a pattern of relations. The split runs deeper than any single scientific question.
Real but sustained — not mind-independent in the strict realist sense.
On this view, the physical world is real enough — it has its own laws, its own conservation principles, its own resistance to wish — but it is not the floor of being. It is sustained by something else: mind, divine attention, computational substrate, or …

Yes — the physical world is fully real, mind-independent, persisting. (55%) ·

Does matter have intrinsic moral standing?
Do rocks, soil, rivers, and stuff in general deserve moral consideration — or only the living, the conscious, the human? The answer turns on what matter is.
Matter is morally considerable derivatively — through what it sustains.
On this view, matter doesn't have standing on its own; it has standing through what it makes possible. Soil matters because it grows food; water matters because it sustains life and mind and practice. Asking whether the rock as such has moral standing slightly misreads …

Matter is morally considerable insofar as it is created or conserved good. (55%) ·

What is our place in nature?
Whether humans are masters of nature, members of nature, or makers of nature is not a question climate science can settle. It depends on what nature is, what we are, and what kind of relationship is possible between us.
Nature is partly what we make of it — concepts, practices, and minds shape the world.
On these views, the 'nature' we live in is not a stand-alone given but something co-constituted by the categories, concepts, technologies, and practices through which we encounter it. There is a world prior to our practices, but what shows up in it as significant, real, …

Should we colonize space?
The drive to extend human presence beyond Earth is sometimes framed as the next chapter of stewardship, sometimes as hubris, sometimes as escape from problems we ought to solve here. Which it is depends on what we take our relationship to nature to be.
The 'space frontier' is partly what we make of it.
On these views, space is not a given canvas on which we paint; it is one more domain that is constituted, in part, by the categories, practices, and imaginations we bring to it. What 'colonisation' even means is a function of frames we choose. The …

Is genetic engineering of food stewardship or domination?
Editing the genomes of the plants and animals we eat is either the natural continuation of breeding — careful improvement of what is given — or a category error that treats biology as raw material rather than as living kind.
What counts as a 'natural' genome is itself a construction.
On these views, the line between 'natural' and 'modified' organisms is partly drawn by the categories we use. Domesticated wheat, hybridised corn, selectively-bred cattle are all 'modifications' that prior generations called natural. The salient question is not whether to modify but which modifications, by whom, …

What happens to "you" when you die?
Whether anything of you persists — and in what sense — depends on what you take a person to be.
You were always a pattern. The pattern propagates.
There was never a "substantial you" to lose. What was real was a pattern of relations — bodily, memorial, social, causal. Those relations don't terminate at the body; they ripple forward through everyone and everything you touched.

Could causation work backwards?
Causation runs one way — the arrow of time is real and structural.
68%
Is the asymmetry between memory and anticipation a real feature of time, or just of us?
The asymmetry is real because time itself has a real direction.
68%
Is the arrow of time a real feature of the cosmos, or only of how we describe it?
The arrow is real and structural; the asymmetry isn't an artifact of description.

Is environmental damage ever truly permanent?
Damage is real and permanent on the relevant timescales. There is no recovery; there is only limitation.

Can a civilization recover from collapse?
Civilizational complexity is hard to build and easy to lose; recovery is at best partial.

Does the second law of thermodynamics mean something morally?
Entropy is what time is. The moral weight, if any, is the weight of working against the current.

Truth is mind-independent, universal, accessible in principle to all.

Is divine omniscience compatible with human freedom?

Does meditation reveal something genuinely timeless?
Meditators are bounded observers reporting unusual brain states; the 'timeless' is metaphorical.

Does prayer change God's mind?
If there is an addressee at all, it is in time; prayer is communication, and may genuinely change what comes next.
