In his article “Famine, Affluence and Morality” Peter Singer gives a seemingly devastating critique of our ordinary ways of thinking about famine relief, charity, and morality in general. In spite of that very few people have accepted, or at any rate acted on, the conclusions he reaches.

He observes, in the world today, there are many people suffering a lot, leading miserable lives, on the margin, prone to calamity whenever natural disasters or wars or other cataclysmic events strike. Many millions of people live on an income equivalent to one dollar a day or less. What, if anything, does morality say one should do about this?

Consider the Strong Singer Principle. He explains that “by without sacrificing anything of comparable
