The first step in the study of the marketing turns out to be the understanding of the needs of the man.
In modern age the thinker who has contributed to the study of the human needs using the theories derived from the psychology is the American psychologist Abraham (Harold) Maslow (April 1, 1908 – June 8, 1970).
Maslow contended that humans have a number of needs that are instinctoid, that is, innate.
These needs are classified as "conative needs," "cognitive needs," and "aesthetic needs." "Neurotic needs" are included in Maslow's theory but do not exist within a hierarchy.
According to Maslow needs and motivations they have the same one exactly meant legacy from a hierarchy of relative overbearingness, cannot therefore be passed to a advanced stage if they have not been satisfied the primary needs.
Maslow postulated that needs are arranged in a hierarchy in terms of their potency.
Although all needs are instinctive, some are more powerful than others.The lower the need is in the pyramid, the more powerful it is.
The higher the need is in the pyramid, the weaker and more distinctly human it is.
The lower, or basic, needs on the pyramid are similar to those possessed by non-human animals, but only humans possess the higher needs.
The first four layers of the pyramid are what Maslow called "deficiency needs" or "D-needs:" the individual does not feel anything if they are met, but feels anxious if they are not met..... Needs beyond the D-needs are "growth needs," "being values," or "B-needs." When fulfilled, they do not go away; rather, they motivate further.
The base of the pyramid is formed by the physiological needs, including the biological requirements for food, water, air, and sleep.
Once the physiological needs are met, an individual can concentrate on the second level, the need for safety and security.
Included here are the needs for structure, order, security, and predictability.
The third level is the need for love and belonging. Included here are the needs for friends and companions, a supportive family, identification with a group, and an intimate relationship.
The fourth level is the esteem needs. This group of needs requires both recognition from other people that results in feelings of prestige, acceptance, and status, and self-esteem that results in feelings of adequacy, competence, and confidence. Lack of satisfaction of the esteem needs results in discouragement and feelings of inferiority.
Finally, self-actualization sits at the apex of the original pyramid.
Returning behind in the history, until ancient Greece, a philosopher it had understood this ideal scale of needs that is be resumption by A. Maslow.
This philosopher is Epicurus (341 BCE, Samos – 270 BCE, Athens) the founder of Epicureanism, a popular school of thought in Hellenistic Philosophy that spanned about 600 years.
Him thinks about needs is”Of desires some are natural and necessary, other natural and not necessary ones, natural neither necessary, but only been born others neither from vain opinion".
Epicuro elaborates one species of catalogue of the needs that if satisfied get eudemonia (literally star with to a good demon, serenity):
• Natural and necessary needs, like as an example drink water for refreshing: these satisfy entire since being it limits to you can completely be overwhelms to you.
• Natural but not necessary needs: like as an example for refreshing drink wine, sure I will not have more silks but I will wish drink more and more wines refines to you and therefore the need will remain in dissatisfied part.
• Natural neither necessary needs neither, like as an example desire of Gloria and riches: these are not natural, they do not have limit and therefore they could not never be satisfied.
From here born the accusation of the Christian fathers of the Church that Epicuro suggested one life style raw and unshonourable material of the man.In Epicuro truth it does not indicate which must be the needs natural and necessary to satisfy since is remitted to the reason of the man to establish which for he are the needs essential, natural to satisfy. For Cesar it can be not influential the need to eat and drink while for he it is truly natural and necessary to satisfy its not eliminating desire of Gloria.
This accusation about this theory survives today too to criticize the think of marketing.
