  Yet on further reflection we may begin to doubt whether such a categorical separation between needs and wants is feasible.  This relates back to the first set of concerns already mentioned in 2.1.1. We might observe that some things we once considered to be more aptly described as preferences, desires or wants have widely come to be thought of as needs. Examples of this phenomenon might include access to computers, the Internet, television sets, refrigeration, and central heating, which are widely thought of as among the necessities of modern life. Given these changes over time concerning what is regarded as a need, the suspicion may arise that a need is nothing more than a desire whose satisfaction has become socially expected, and therefore lacks the special moral force that its defenders claim for it.
