"Science offers no alternative framework. The best it can offer is wealth in a wide sense of the term, that is to say, the satisfaction of a wide variety of desires. It cannot conceive of any means of achieving that escape from desires we call "contentment" otherwise than through the satisfaction of those desires; it has not yet learnt that there is no limit to the multiplication of desires, nor that, since different people's desires are often mutually incompatible, an indefinite multiplication of desires increases conflict as well as discontent."
