Maslow's hierarchy of needs is a theory in psychology, proposed by Abraham Maslow in one of his writings titled "A Theory of Human Motivation." Maslow includes his observations on innate human needs. The hierarchy of Maslow's primary innate human needs is as follows: physiological, safety, social, esteem and self-actualization.
Physiological needs are obvious, basic requirements for continued existence. These needs include: food, water, air, shelter, breathing, sexual activity and homeostasis.
Individuals desire predictable, consistent, reasonable and orderly life full of justice. This would be a place where safety and protection reign. Some examples of these needs are: health insurance, medical insurance, personal security (a secure job), financial security (savings account) and good health.
All humans would like to feel as if they belong to something. Some social needs include emotionally-based relationships such as: friendships, marriages and a supportive family. In the absence of these needs loneliness and depression may arise.
Esteem characterizes the normal human need and desire to be accepted by others. Individuals must engage themselves to gain recognition and participate in activities that allow them to contribute. This will allow them to feel accepted and a sense of self-worth. Inner competence is key.
This level of need refers to a person realizing their full potential and acting on it. Maslow describes this need as the one that will allow individuals to become who they are capable of being.
