Work Classification Layer
Compare Works
Pick two or more works to set their attribute fingerprints, dimension-by-dimension passages, and shared school embodiments side by side. Especially useful for author-stage comparisons (Wittgenstein early vs late) and for setting a single tradition's foundational texts against each other.
Practical Ethics
Singer's 1979 systematic textbook of preference-utilitarian applied ethics

Dimension-by-Dimension Evidence
What each work's passages reveal about its stance on each of the six dimensions.
Time
Practical Ethics
The 1979 first-edition moment; the broader 1979-2011 multi-edition arc.
Space
Practical Ethics
The contemporary-Anglophone analytic-applied-ethics setting.
Matter
Practical Ethics
The contemporary ethical-political subjects (animals, abortion, poverty, etc.).
Observer
Practical Ethics
Singer as proper utilitarian-applied-ethics theorist.
Energy
Practical Ethics
The systematic-ethical-philosophical energies.
Information
Practical Ethics
The systematic content across applied-ethical topics.
Internal Tensions
Where each work's argument pulls against itself.
Practical Ethics has been variously assessed — defenders see foundational applied-ethics achievement, deontological-virtue-ethics critics maintain rival positions on specific applied questions.
