would cause the degradation of society.

There is a reason for the variations of personality type, and it is an evolutionary one.

Various types, during the evolution of man, played certain roles in culture. An NT would most

likely be a shaman or witch doctor in primitive times, an SP a craftsman, etc. But a society does

not need as many shamans as it does craftsmen and hunters, thus, NTs are found in smaller

percentages. A similar occurrence with intelligence is found. Higher intelligence tends to lead to

deviation from the norm, but human cultures require conformity. Thus, we find certain personality

types and intelligences existing in small percentages. This being so, it is dangerous to apply quality

of happiness to any cost/benefit analysis, as all types rely on each other for survival.

Mill was an INTP and very intelligent, but in his formulation of Utilitarianism he has

assumed that all are (or have the potential) capable of viewing view the world as he does. Mill,

however was wrong. While happiness may be objective, what brings about this happiness varies

from type to type. Therefore, since different types value different forms of happiness, Mill can not

apply quantity and quality to his cost benefit analysis, for his moral judges are most likely to be

NTs and not SPs, and are therefore going to apply a different guideline of quality than the SP. This

being so, we are forced to criticize Mill's Utilitarianism for being insufficient in acknowledging

that while the desire for happiness may be universal, happiness itself is not and thus can't be used

as a grounding for Utilitarianism.


Personality plays a major role in creating the philosophies of Kant and Mill. Without either

philosophers being aware that there are naturally occurring differences in personality types, they

automatically have assumed that their personality type (whether or not consciously so) is the

standard. Both Kant and Mill, because of their similar personality type, highly value certain

personality/temperament types (NTs of all the temperaments) and a well-developed intelligence.

Kant and Mill value intelligence as all with their similar personality type do. By understanding this

perspective, not of the culture, but of the individual, we can understand the reasoning behind Kant

and Mill's philosophy. Not only will we necessarily have a better understanding of a philosopher's
