Needs and medicine.

It is argued that human needs are not facts (properties, states, processes, relations) about people, but are values. The reasons presented for this position are (1) that needs are goal oriented and goals are things people value, (2) that 'need' functions as a basic motivational term, and (3) that disagreements about what people need are disagreements in attitude toward, and emotional attachment to, things variously considered to be valuable. If human needs are not facts, then, of course, health or medical needs are not. Viewing health or medical needs as discoverable facts, rather than values, engenders certain difficulties in the following areas of concern: (a) Deciding when surgery is necessary and when unnecessary; (b) Defining the concepts of health and disease; (c) Evaluating some consequences of the development of medical science and technology; and (d) Understanding the alleged conflict between patients' health needs and their human rights.
