Every organism has needs, some basic some complex. And the more complex the organism the more those needs affect that organisms chances of survival.
– from “Psychology - The Search for Understanding” by Janet A. Simons, Donald B. Irwin and Beverly A. Drinnien
Maslow has set up a hierarchy of five levels of basic needs. Beyond these needs, higher levels of needs exist. These include needs for understanding, esthetic appreciation and purely spiritual needs. In the levels of the five basic needs, the person does not feel the second need until the demands of the first have been satisfied, nor the third until the second has been satisfied, and so on. Maslow's basic needs are as follows: physiological, safety, belongingness, esteem and self-actualization.
1. Physiological Needs
These are biological needs. They consist of needs for oxygen, food, water, and a relatively constant body temperature. They are the strongest needs because if a person were deprived of all needs, the physiological ones would come first in the person's search for satisfaction.
2. Safety Needs
When all physiological needs are satisfied and are no longer controlling thoughts and behaviors, the needs for security can become active. Adults have little awareness of their security needs except in times of emergency or periods of disorganization in the social structure (such as widespread rioting). Children often display the signs of insecurity and the need to be safe.
3. Needs of Love, Affection and BelongingnessFor our purposes we only usually need to discuss these 3 groups. In a cataclysmic situation where the Safety Needs and above are out the window folks will naturally revert to taking care of their physical needs first.Its just in our nature. With that being said, further posts will usually concern one or more of the major topics addressed in Physiological Needs: Food, Water, Shelter, Sleep Along with the additional Safety needs of Security, Stability, and Order.
When the needs for safety and for physiological well-being are satisfied, the next class of needs for love, affection and belongingness can emerge. Maslow states that people seek to overcome feelings of loneliness and alienation. This involves both giving and receiving love, affection and the sense of belonging.
Without our basic needs met and a little order things can go downhill rapidly.
