Garrett Hardin argues for a very harsh thesis: we simply should not provide aid to people in poor countries. His argument is consequentialist: he claims that the net result of doing so would be negative -- would in fact be courting large-scale disaster. One of the things that we will notice about Hardin's essay, however, is that whether he is right or wrong, he paints with a very broad brush. This makes it a good essay for the honing of your philosophical skills; you should notice that there are many places where the reasoning procees with less than total care.
Hardin begins with metaphors. He points out that while the metaphor of earth as a grand spaceship has a certain popularity (or did 23 years ago) it is a flawed metaphor nonetheless. A spaceship has a captain, and couldn't survive without one. The earth has nothng vaguely resembling a captain, the United Natins in particular being a "toothless tiger."
Whatever we may make of the metaphor, we shold note what it was meant to support. By Hardin's own account, it was a way of bolstering the following proposition:
...no single person or instituion has the right to destroy, waste or use more than a fair share of its resources.
The correctness of this view would hardly seem to depend on whether the earth has a captain. But Hardin's reply would no doubt be that if we ae in a situation in which allowing everyone a "fair share" will lead to disaster, then this seemingly innocuous moral principle is dangerous.
In any case, Hardin prefers a different metaphor. Rich nations can be seen as lifeboats. The seas around them are filled with poor people who would like to get in the lifeboat or at least get a shae of the walth. Should we let them in?
