Introverted feeling strives for an inner intensity that is unrelated to any external object. It devalues objective reality and is rarely displayed openly. When it does appear on the surface, it generally seems negative or indifferent. The focus of such feeling is upon inner processes and latent, primordial images. At its extreme, it may develop into mystical ecstasy.
The introverted feeling type is brooding and inaccessible, although may also hide behind a childish mask. Such a person aims to be inconspicuous, makes little attempt to impress and generally fails to respond to the feelings of others. The outer, surface appearance is often neutral, cold and dismissive. Inwardly, however, feelings are deep, passionately intense, and may accompany secret religious or poetic tendencies. The effect of all this on other people can be stifling and oppressive.
vs.
Extraverted sensation strives for intensity of experience derived from concrete objects and physical activities. Consciousness is therefore directed outward to those objects and activities that may be expected to arouse the strongest sensations.
The extraverted sensation type is a realist who seeks to experience as many concrete sensations as possible - preferably, but not necessarily, ones that are pleasurable. These experiences are seen as ends in themselves and are rarely utilized for any other purpose.If normal, such persons are sensualists or aesthetes who are attracted by the physical characteristics of objects and people.
They dress, eat and entertain well, and can be very good company. Not at all reflective nor introspective, they have no ideals except sensory enjoyment. They generally mistrust inner psychological processes and prefer to account for such things in terms of external events (e.g., they may blame their moods on the weather).
If extreme, they are often crudely sensual and may exploit situations or others in order to increase their own personal pleasure.
I've highlighted the parts that seem especially contradictory to me. But I sum it up as basically "I must do what is right" vs. "If it feels good, do it." It's like constantly shooting at a target, where sometimes a forcefield stops the shot, and sometimes it gets through.
