Abstract
If options cannot be defended, then there is a general requirement to promote the good. Appropriate political and social structures have an important place in seeing to it that this requirement is met, and in somewhat reducing the nature of the sacrifices that may be required in meeting it; but there is no getting around the fact that morality can demand a significant overall sacrifice of one's interests. However, moral agents are free, and we are required to use this freedom to change ourselves so as to better meet the demands of morality.
