Peter Singer is a contemporary Australian philosopher best known for his work in bioethics and his advocacy for animal rights and utilitarian ethics. His influential ideas challenge traditional views on morality, particularly regarding the treatment of animals, the environment, and issues surrounding healthcare and reproductive ethics.
Utilitarianism: An ethical theory that advocates for actions that maximize happiness and well-being for the majority, often associated with the principle of 'the greatest good for the greatest number.'
Speciesism: The discrimination against beings based solely on their species, leading to unequal consideration of interests among different species, often criticized by Singer in his animal rights advocacy.
Effective Altruism: A philosophical and social movement that uses evidence and reason to determine the most effective ways to improve the world, closely tied to Singer's ideas on philanthropy and moral responsibility.
