Physical pain is only a manifestation of passion. There are many other ways to exemplify how animals experience passion.
I too do not think that you need a great intellect to come up with works of art, but you need an intellect of some kind. One far superior to that of most brutes.
Indeed, there are many highly intelligent ESs, for the present day applied typology this point is moot. As regardless of what type you are, you are in the position to use your faculties of abstract thought with relative ease.
The point was that of pure typology, of philosophy of mind and not of applied typology and or psychology.
The argument is Intution, Thinking and Introversion have evolved from Sensation, Extroversion and Feeling. At the present day being an Extrovert, Sensor and an Extrovert still gives you ample access to the intellectual faculties of Introversion, Intuition and Thinking as we really have come a long way up the path of evolution. In other words, because we are already highly evolved, all of us, irrespectively of natural predilections have a high potential to further our intellectual faculties.
For this reason it is possible and many of us may have observed this happen, for the ESs to surpass the INs in intellect.
Most of the bickering in this thread here resulted due to a confusion of pure typology for applied typology.
