Do you really choose?
If the brain is a physical system and physical systems are governed by laws, then every choice is also a chain of causes — which raises the question of what was really left to choose.
Choice is structural illusion — every event is fixed by the prior state.
On this view, the future is fixed by the present, and the observer is a recipient of causes rather than an originator of them. The sense of choosing is real — but what is being chosen is itself a consequence of brain states that were …
Roads not taken The future is open and you are a genuine origin of it. (69%) · Choice is real within a determined order — agency and determinism aren’t opposites. (9%) · Even if the universe is undetermined, you are not the chooser. (6%)

Are addicts responsible for their addiction?
Addiction looks from one angle like the textbook case of agency failing — a person doing what they don't, in any meaningful sense, want to do. From another angle it looks like agency at work in hard conditions. Which it is depends on what agency is.
The addict's behaviour is the outcome of causes; 'responsibility' is a useful fiction, not a metaphysical fact.
On this view, the addict's brain state, history, genetics, and circumstances jointly produce the behaviour, and there is nothing inside the person that could have produced anything else. Calling the addict responsible is at best a social tool — useful for the deterrent and rehabilitative …
Roads not taken The addict could have chosen otherwise — that's why recovery is real. (69%) · The addict is genuinely responsible within a determined order. (9%) · Even if the universe is undetermined, the addict isn't the chooser. (6%)

Should we hold AI systems responsible for what they do?
When an autonomous AI takes an action that harms someone, the question of who or what is responsible — the developer, the operator, the model itself — turns on whether the model is the kind of thing that can be a responsible agent.
An AI's behaviour is fully determined by training and input; 'responsibility' applies if at all to its makers.
On this view, the AI's output is a function of its training data, its architecture, and the input it received. There is no extra fact about the AI that could ground its responsibility, because there is no extra fact about the AI that could have …
Roads not taken An AI without a free will is not the kind of thing that can be responsible. (69%) · The AI can be a genuine agent within determined conditions — and therefore genuinely responsible. (9%) · Neither AIs nor anyone else are the locus of free agency; the question is the wrong one. (6%)

Is the universe running out of usable energy?
The heat death of the universe — entropy maxed out, no further work possible — is among the more sobering implications of mainstream physics. Whether it is structurally inescapable depends on what kind of finitude the cosmos has.
Both time and matter are unbounded; 'running out' is misframed.
On this view, the cosmos has neither a temporal horizon nor a material exhaustion point. The framing of running out presupposes bounds that the cosmos doesn't have. Energy gradients perpetuate; new configurations emerge; the categories that make heat-death scary don't apply at the cosmic scale.
Roads not taken Time is unbounded but matter is finite; usable energy can fail without time failing. (47%) · Time both has and lacks bounds depending on the level you ask at; finitude is conventional. (26%) · The cosmos has bounds; heat death is a real horizon. (12%)
Distinctive · only 15% of schools agree (31/202)
Are natural resources fundamentally finite, or only practically so?
Whether we can grow our way out of resource constraints — or whether the cosmos sets limits the economy ultimately must obey — depends on what kind of finitude matter has.
Resources are practically inexhaustible on cosmic scales; terrestrial limits are engineering.
On this view, matter and time are both unbounded at the largest scales. Terrestrial resource limits are real engineering and political constraints but not metaphysical ones; the cosmos can in principle support whatever expansion intelligence is capable of.
Roads not taken Time goes on but matter is bounded; we are eventually constrained even with infinite time. (47%) · The finitude question is level-dependent; resource ethics happens at the level that constrains us. (26%) · Resources are finite in the strict sense; living well requires accepting the limit. (12%)

Could we owe future generations more than is materially possible to provide? Both time and matter are unbounded; we cannot in principle owe more than is possible. 15% How much weight do future people deserve? Future people are as real as you are — and their interests count for as much. 47% Is regret rational? The past is as real as the present; regret is a real attitude toward a real thing. 47% Do we owe extinct species something we cannot give them? Extinct species are as real as we are; they have standing. 47%
Matter · 7 dilemmas, all mainstream
Is the world created from nothing? Yes — matter was created and is conserved as a real substance. 55% Is the physical world fully real? Yes — the physical world is fully real, mind-independent, persisting. 55% Does matter have intrinsic moral standing? Matter is morally considerable insofar as it is created or conserved good. 55% What is money? Money is a real institution with intrinsic features. 54% What is a nation? A nation is a real moral community with intrinsic character. 54% What makes someone male or female? Sex is a real biological kind with given content. 54% Should we edit the human germline? Human nature is a real biological kind given by reproductive biology or by creation; editing the germline transgresses what is given. 54%

Is environmental damage ever truly permanent?
Extinction is forever; soil erosion takes centuries to repair; the carbon we emit will warm the climate for millennia. But whether 'forever' or 'millennia' means what they say depends on what kind of process the universe is.
What appears irreversible is reversible by the right action.
On this view, the appearance of permanence is a function of limits we have not yet exceeded. Divine action, sufficiently advanced technology, intentional restoration practice can in principle reverse what now appears irreversible. The lost is not gone for good; it is gone for now.
Roads not taken Damage is real and permanent on the relevant timescales. There is no recovery; there is only limitation. (66%) · Loss is part of cycles; what disappears returns in another form. (17%) · From the standpoint of the One, the categories of permanence and loss are conventional. (8%)

Can a civilization recover from collapse?
Rome fell; Maya cities emptied; Bronze Age trade networks collapsed in a single generation. Whether what was lost can be recovered — or whether collapse is structurally final — depends on what kind of process civilization is.
Civilization is the kind of order that can in principle be restored.
On this view, the order that constitutes civilization — information, practices, institutions, ethics — is not destroyed by collapse, only dispersed. Given the right work, by humans, divine action, or both, it can be reconstituted. The historical pattern of recovery and renewal is partial evidence; …
Roads not taken Civilizational complexity is hard to build and easy to lose; recovery is at best partial. (66%) · Civilization rises and falls in cycles; recovery is structural to history. (17%) · From the One's vantage, civilizational categories are themselves conventional. (8%)
Distinctive · only 5% of schools agree (11/202)
Does the second law of thermodynamics mean something morally?
The universe trends from order to disorder. Whether that physical pattern carries moral weight — making the preservation of order, beauty, complexity a kind of cosmic duty — depends on whether time has the kind of structure morality could lean on.
Apparent entropy is reversible in principle; the moral category is restoration.
On this view, the second law describes local pattern rather than cosmic destiny. What is broken can be repaired — by divine action, by human work, by energetic intervention. The moral weight of restoration is real and not borrowed from the physics. The cosmos is …
Roads not taken Entropy is what time is. The moral weight, if any, is the weight of working against the current. (66%) · Local entropy increase is part of a cycle; the moral category is participation in the cycle. (17%) · From the One's vantage, the second law is itself a feature of the conventional, not the ultimate. (8%)

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.
Subject to a real natural order we did not make.
On these views, nature is a real, ordered, mind-independent reality that we are inside of but did not construct. Our fundamental posture toward it is one of observation, discovery, and humility before laws that are not ours to make. Stewardship and conservation are real obligations, …
Roads not taken Active in a real nature — we cultivate, steward, transform. (48%) · Nature is partly what we make of it — concepts, practices, and minds shape the world. (15%) · Embedded in a web — partners with the more-than-human world. (15%)

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.
Nature includes its limits; colonisation is bounded by what the cosmos allows.
On these views, humans operate within a given natural order whose laws and limits set the terms. Space colonisation is fine to the extent that it is actually possible — radiation, gravity wells, biological tolerances — and folly to the extent that it requires denying …
Roads not taken Cultivating worlds beyond Earth is the next form of stewardship. (48%) · The 'space frontier' is partly what we make of it. (15%) · Colonisation continues the work that ended the wisdom of seven-generation thinking. (15%)
