Explanation:

Maslow has shown that an individual has a hierarchy of needs that shape his reaction to any particular situation. Maslow advanced the following important propositions about human behavior:

• The man is a wanting being: Man, always wants and he wants more. But what he wants depends upon what he already has. As soon as one of the man’s needs is satiated, another appears in the place. This process is unending and continuous from birth to death.
• A satisfied need is not a motivator: A satisfied need is not a motivator of human behavior. Only the unsatisfied needs motivate behavior.
• A Need can be arranged in a number of levels: When a need can be arranged in a number of levels a hierarchy is formed. The satisfaction of lower level needs demands the fulfillment of the next level. That is, human needs move in an ascending order, from the lowest to the highest levels.
