Maslow’s hierarchy of need or “the theory of human motivation” (Maslow 1946, cited by Hoffman, 1996) shows, a sequence of five human needs in ascending stages, from the most basic physiological need, through the needs of safety, love and belonging, self-esteem and self-actualization. Once a person’s need is accomplished, the motivation for a need of a higher level arises. Nevertheless “All needs are interrelated and interdependent, ... a hierarchy of relative prepotency” (Maslow 1946, cited by Hoffman, 1996), therefore different aspects of these needs could be accomplished depending on the motivation arisen, during the constant process of the person's development. Maslow believed that the unaccomplished need could be positively transformed into the motivation for self-improvement. Learning to love and to be loved, having self-respect and self-fulfillment, are only possible to achieve once the most basic needs, such as physiological and safety needs been fulfilled.
