You broach a truly fascinating topic, one I'd enjoy exploring in a separate thread.
Psychological character and temperament was my first fascination, the one that got me started in the field.
Of the three foundational philosophical bases -- ontological, epistemological and utilitarian -- I have noticed a connection between utilitarianism and Jung, Myers-Briggs, Keirsey psychological character and temperament psychology's "sensing perceptive" Dionysian temperament.
These live-in-the-moment playful people, along with their complement, "sensing judging" Epimetheans who are grounded-in-the-past responsible people, comprise, as Keirsey estimates, around 85 percent of the world's population, split roughly equally between the two.
Dionysians are for the most part respectful of the rights of others, but they are the most susceptible, when suffering relative emotional immaturity, to the violation of the rights of others, and Dionysians greatly comprise the largest percentage of prison inmates.
The Dionysian temperament is indeed at play in the fun, free child, and, in an adult world that can sometimes be stressful and dour, there is a great compensatory attraction to Dionysian-like pleasurable activities.
With regard to the psychological character and temperaments, there are even places in the brain where cerebrally localized activity reflects character and temperament.
This is all fascinating stuff, but I digress from the topic of this thread.
Start another thread on the relationship of psychological character-temperament and philosophy to U.S. political position on the issues, and I'm there, time allowing.
