The demand can become relentless
Impartial prevention may leave too little room for personal projects, special relationships and limits on moral exhaustion.
Contemporary philosophy · 1946–
Peter Singer
Singer presses impartial concern into everyday life, asking whether distance, species and ordinary spending habits are morally relevant differences.
Peter Singer is an Australian philosopher known for work in practical ethics. His arguments about animal suffering, global poverty and effective giving press readers to extend equal consideration beyond familiar moral boundaries.

The question he enters
The question Peter Singer enters
If you can prevent something very bad at a modest cost, what excuses doing nothing?
The central move
Strip away the comfortable distance
Singer's practical arguments ask which differences genuinely affect moral consideration. Sentience makes suffering morally important across species; physical distance does not by itself erase a preventable need. His famous cases deliberately connect abstract impartiality to ordinary choices about food, money and rescue.
Key ideas
Terms that carry the argument.
- Equal consideration of interests
- Like interests deserve comparable weight even when the beings who possess them differ.
- Sentience
- The capacity for suffering or enjoyment as a central basis for moral consideration.
- Speciesism
- Discounting interests merely because a being belongs to another species.
- Preventable suffering
- The claim that distance and custom do not cancel a strong duty to prevent severe harm at modest cost.
Where the view strains
Objections and limits.
Aggregation can threaten protection
A utilitarian framework must explain how individuals are secured against sacrifice for a larger total benefit.
