Physiological & Psychological Needs

Physiology pertains to the physical, the human body. The physical needs of man are the most basic, according to psychologist Abraham Maslow in his Theory of Motivation (1943). These physiological needs - breathing, food, sleep, sex/reproduction, water, homeostasis, excretion, warmth & other bodily needs - provide the base for the pyramid of needs that start at the physiological and taper/peak at the abstract/psychological because in order for man to survive, the physiological needs must be met first. Without food, water, and shelter for instance, death will occur. The physiological points at the necessity to survive, the most basic challenge at life all living things face. The rest of the planet's flora & fauna face this challenge as a reality in making it to the next epoch. Since time immemorial many a species have gone extinct due to their inability to meet the needs of their physiology from their immediate environment. Some species adopt (the wholly mammoth during the ice age), some evolve (man from Australopithecus to Neanderthals to Homo Sapiens) and some die out (like the dodo & the dinosaurs).

Today's human beings have tamed much of the planet and climbed at the top of the food chain, ruling the planet and going beyond the boundaries of Earth into Space to discover the small part of the universe due to their unique nature that have allowed them the facility to rule the planet as they wished - they are sentient, they have the ability to learn, enquire & understand. Human beings of today are so far removed from their ancestors. While the Ice Age man did live in social groups, our world is the result of the thousands of years of evolution from where civilizations & cultures taught man to overcome the challenges of the physiological & took us to another level in terms of self-actualization: psychological needs. When the physiological needs of man are met, then the psychological follows - they are tied to the physiological as the physiological needs, when met without question bring about the human phenomenon of 'being'; Philosopher Rene Descartes during the enlightenment argued that the ability to think, to be is due to human thought and to question, to think allows for a state of 'being'. Maslow proposes that when the physiological is met, man starts to work at providing security and safety to himself which in today's society is manifested by employment to secure resources to continually provide the physiological. Here security of one's body, health, family, morality & property is worked at and when met, allows for the individual to move to secure the next level of need, that of love, belonging & intimacy, ...
