Dimension-by-Dimension Evidence
What each persona's writings reveal about their stance on each of the six dimensions.
Time
Peter Singer
Standard linear physical time; ethics is forward-looking, oriented to consequences.
Space
Peter Singer
Standard substantival space; global obligations span the entire surface of the Earth.
Matter
Peter Singer
Standard substantival matter; sentient beings (human and non-human animal) are the ethically relevant subjects.
Observer
Peter Singer
Plural sentient observers, with their preferences as the ethically primary data. No metaphysical agency.
Energy
Peter Singer
Standard physics.
Information
Peter Singer
No personal afterlife in the framework.
Internal Tensions
Where each persona's working synthesis strains against itself.
Singer's positions on infanticide of severely disabled newborns, voluntary euthanasia, and the moral status of fetuses generated sustained protest from disability-rights groups and Catholic philosophers; his 1999 appointment at Princeton was accompanied by major protests. The effective-altruism movement he co-founded has had its own internal crises (the FTX-SBF collapse most visibly). Singer's methodological consistency — follow the premises wherever they lead — is his strength and the source of most of the controversies.
