Problems concerned with recognizing, identifying, analyzing or assessing human needs are investigated by many authors in various approaches. The needs are seen as a problem of social sciences (considering human needs as something that is inextricably linked with the human existence and action). The needs are considered in economy (as one of key engine of market development). The needs are also important factor of engineering activities. The ideas like "Assessment of Needs" are also seen in medical publications (needs of patients). Since a time when I try to implement to scientific debate the idea of "Engineering of Needs", the question concerning the ethical dimension of needs is - on one hand - seen as really important, but - on the other hand - still open.
