The document discusses Maslow's hierarchy of needs which ranks human needs in order of importance. It separates needs into physiological needs like food and water, safety needs like security and shelter, love and belonging needs like friendship, esteem needs like confidence and achievement, and self-actualization needs like personal growth. The hierarchy suggests that lower level needs must be satisfied before higher level needs can be pursued. The document also distinguishes between needs which are essential for survival and wants which are desires but not required for basic living.
