A '''hierarchy''' is an ordering of persons, ideas, or constructs from less to greater importance, in a tiered organizational structure.  Organizations may have a hierarchy, both formally and informally: for example, the [[Senate]] formally has no internal hierarchy, but informally, senior Senators may "rank" above junior Senators.

Intellectually, intangible ideas may be expressed in a hierarchical form.  An idea common in [[philosophy]] is the "hierarchy of needs," a theory proposed by Abraham Maslow, who argued that each individual must meet different needs in ascending order before attaining [[self-actualization]], the pinnacle of human self-awareness.<ref>http://honolulu.hawaii.edu/intranet/committees/FacDevCom/guidebk/teachtip/maslow.htm</ref>
