How does Aristotle justify human superiority?
Humans alone have rationality → can achieve eudaimonia → higher moral status than animals/ecosystems.
Why do only humans have moral worth under Kant?
Humans are rational autonomous beings with moral reasoning → ends in themselves. Animals/ecosystems = instrumental value.
How does classical utilitarianism reinforce human exceptionalism?
It aims to maximize human happiness; animal/ecosystem well-being is secondary in practice.
What was the shared view across Aristotle, Aquinas, Kant, Descartes?
Animals lack rationality/awareness → exist for human use → no intrinsic moral status.
Who is Singer and what is his main ethical basis?
What makes an action ethical under preference utilitarianism?
It satisfies affected beings’ preferences—not maximizes happiness.
How does preference utilitarianism apply in health care?
Honors autonomy; respects patients’ preferences; includes sentient animal preferences (avoid suffering).
Singer’s principle? - equal consideration of interests
idea: Give equal moral weight to similar interests of humans and non-human animals
implication: decisions about animals should not prioritise human needs or desires over animal welfare (animal testing?)
challenge to norms: urges a shift towards a more balanced ethical approach to animal treatment
What is speciesism?
Prioritizing humans solely because they are human; morally comparable to racism/sexism.
Does equal consideration mean identical treatment?
No—only respect interests (e.g., freedom from pain); not same rights as humans.
