    What Should We Do About Future Generations?Yew-Kwang Ng - 1989 - Economics and Philosophy 5 (2):235.
    Parfit's requirements for an ideal Theory X cannot be fully met since the Mere Addition Principle and Non-Antiegalitarianism imply the Repugnant Conclusion: Theory X does not exist. However, since the Repugnant Conclusion is really compelling, the Impersonal Total Principle should be adopted for impartial comparisons concerning future generations. Nevertheless, where our own interests are affected, we may yet choose to be partial, trading off our concern for future goodness with our self-interests. Theory X' meets all Parfit's requirements except the Mere (...)

  2. Towards Welfare Biology: Evolutionary Economics of Animal Consciousness and Suffering. [REVIEW]Yew-Kwang Ng - 1995 - Biology and Philosophy 10 (3):255-285.
    Welfare biology is the study of living things and their environment with respect to their welfare. Despite difficulties of ascertaining and measuring welfare and relevancy to normative issues, welfare biology is a positive science. Evolutionary economics and population dynamics are used to help answer basic questions in welfare biology : Which species are affective sentients capable of welfare? Do they enjoy positive or negative welfare? Can their welfare be dramatically increased? Under plausible axioms, all conscious species are plastic and all (...)

  3. Welfarism and Utilitarianism: A Rehabilitation*: Yew-Kwang Ng.Yew-Kwang Ng - 1990 - Utilitas 2 (2):171-193.
    Utilitarianism seems to be going out of fashion, amidst increasing concerns for issues of freedom, equality, and justice. At least, anti-utilitarian and non-utilitarian moral philosophers have been very active. This paper is a very modest attempt to defend utilitarianism in particular and welfarism in general. Section I provides an axiomatic defence of welfarism and utilitarianism. Section II discusses the divergences between individual preferences and individual welfares and argues in favour of welfare utilitarianism. Section III criticizes some non-utilitarian principles, including knowledge (...)

    Does Suffering Dominate Enjoyment in the Animal Kingdom? An Update to Welfare Biology.Zach Groff & Yew-Kwang Ng - 2019 - Biology and Philosophy 34 (4):40.
    Ng :255–285, 1995. https://doi.org/10.1007/bf00852469) models the evolutionary dynamics underlying the existence of suffering and enjoyment and concludes that there is likely to be more suffering than enjoyment in nature. In this paper, we find an error in Ng’s model that, when fixed, negates the original conclusion. Instead, the model offers only ambiguity as to whether suffering or enjoyment predominates in nature. We illustrate the dynamics around suffering and enjoyment with the most plausible parameters. In our illustration, we find surprising results: (...)

    Intergenerational Impartiality: Replacing Discounting by Probability Weighting. [REVIEW]Yew-Kwang Ng - 2005 - Journal of Agricultural and Environmental Ethics 18 (3):237-257.
    Intergenerational impartiality requires putting the welfare of future generations at par with that of our own. However, rational choice requires weighting all welfare values by the respective probabilities of realization. As the risk of non-survival of mankind is strictly positive for all time periods and as the probability of non-survival is cumulative, the probability weights operate like discount factors, though justified on a morally justifiable and completely different ground. Impartial intertemporal welfare maximization is acceptable, though the welfare of people in (...)

    Ng and Singer on Utilitarianism: A Reply.Yew-Kwang Ng & Peter Singer - 1983 - Canadian Journal of Philosophy 13 (2):241 - 242.
    Ng and singer derive the principle of utility from the fact of finite sensibility and another principle, weak majority preference: "for a community of n individuals choosing between two possibilities, x and y, if no individual prefers y to x, and at least n/2 individuals prefer x to y, then x increases social welfare and is preferable." this derivation is regarded as incorrect in a comment. this reply explains why the derivation is valid and shows that the comment is based (...)

    An Argument for Utilitarianism.Yew-Kwang Ng & Peter Singer - 1981 - Canadian Journal of Philosophy 11 (2):229 - 239.
    Many utilitarians accept Bentham's view that to argue for the principle of utility is as ‘impossible as it is needless'. They take utilitarianism as a first principle which one either accepts or does not. They do, of course, defend utilitarianism against objections, and make objections to other ethical positions; but the principle of utility itself, they hold, must stand on its own merits. In this article we use a different approach. We introduce a principle, which we call ‘Weak Majority Preference', (...)

    From Separability to Unweighted Sum: A Case for Utilitarianism. [REVIEW]Yew-Kwang Ng - 2000 - Theory and Decision 49 (4):299-312.
    After reviewing the compelling case for separability (`social welfare is a separable function of individual utilities'), an argument is advanced for utilitarianism (defined as `social welfare is the unweighted sum of individual utilities'). Basically, a compelling individualism-type axiom leads us to (social welfare as an) unweighted sum (of individual utilities), given separability.

  14. Markets and Morals: Justifying Kidney Sales and Legalizing Prostitution.Yew-Kwang Ng - 2019 - Cambridge University Press.
    Considering efficiency, equality, and morality, this book argues for qualified market expansion, particularly in legalizing kidney sales and prostitution. Legalizing prostitution will benefit both men and women, as argued in a chapter jointly written with Yan Wang. Blood donation without monetary compensation can still result in adequate blood supply if schools educate children that blood donation can actually benefit a donor's health. As a society becomes more advanced, with higher incomes and a better educated populace, more activities can be subject (...)
