Unfortunately for ethical egoism, the claim that we will all be better off if every one of us does what is in his or her own interest is incorrect. This is shown by what are known as "prisoner's dilemma" situations, which are playing an increasingly important role in discussions of ethical theory... At least on the collective level, therefore, egoism is self-defeating - a conclusion well brought out by Parfit in his aforementioned Reasons and Persons.
Interpretation
Ethical egoism suggests that individuals acting in their own interest will benefit everyone, but this is flawed, as shown by the prisoner's dilemma.
The quote by Peter Singer critiques the ethical theory of egoism, which posits that individuals should act in their own self-interest for the betterment of society. However, he points out that this approach can lead to collective harm, particularly in scenarios like the prisoner's dilemma, where mutual cooperation yields better outcomes than self-serving actions. Essentially, Singer emphasizes that pursuing one's own interests can be self-defeating when it comes to societal welfare.
In practice
In a debate on ethical theories, one might use this quote to illustrate the flaws of selfishness in decision-making.
The belief that the animals exist because God created them - and that he created them so we can better meet our needs - is contrary to our scientific understanding of evolution and, of course, to the fossil record, which shows the existence of non-human primates and other animals millions of years before there were any human beings at all.
Pain and suffering are in themselves bad and should be prevented or minimized, irrespective of the race, sex, or species of the being that suffers. How bad a pain is depends on how intense it is and how long it lasts, but pain of the same intensity and duration are equally bad, whether felt by humans or animals.
What is faith? If you believe something because you have evidence for it, or rational argument, that is not faith. So faith seems to be believing something despite the absence of evidence or rational argument for it.
Almost everybody accepts that some people can be killed. 'The concept of 'brain death' - the belief that people on respirators can legitimately be killed - shows that.
If we all think only of our own interests, we are headed for collective disaster - just look at what we are doing to our planet's climate.
Even in the era of AIDS, sex raises no unique moral issues at all. Decisions about sex may involve considerations about honesty, concern for others, prudence, and so on, but there is nothing special about sex in this respect, for the same could be said of decisions about driving a car. (In fact, the moral issues raised by driving a car, both from an environmental and from a safety point of view, are much more serious than those raised by sex.)
When we were kids we always used to say, ‘Okay, whoever dies first, get a message through.’ When John died, I thought, ‘Well, maybe we’ll get a message,’ because I know he knew the deal. I haven’t had a message from John.
There is nothing so secular that it cannot be sacred, and that is one of the deepest messages of the Incarnation.
June suns, you cannot store them To warm the winter's cold, The lad that hopes for heaven Shall fill his mouth with mould.
I wasn't the biggest Captain America fan, but increasingly, I see him as a great character. Winter Soldier really got into what it meant to actually represent America.
I know that what you call 'God' really exists, but not in the form you think; God is primal cosmic energy, the love in your body, your integrity, and your perception of the nature in you and outside of you.
Many might go to Heaven with half the labor they go to hell.
