If he was taught speech by his parents, that means that the parents were educated by a society somewhere.
Leaving that point, we consider the fact that he was successfully "brought to the city" and that if someone was to be assigned to "outfit" him, then he was brought to the city willingly.
So i ask if the people who discovered him were able to communicate with him effectively, so that he wasn't dragged out of his home. This can be a possibility because he was taught to speak. We can only assume that the language of the discoverers or one of the discoverers was the same as his because he was coaxed to come with them sans violence.
Assuming that the previous assumption is true and considering the first point about the parents gaining the knowledge of speech from some society, i question why the man was shown to be without worldly skills to begin with. Speech carries with it symbolism of elements and values from society. If he were taught to speak the same tongue as his discoverers then he should also have roughly a basic understanding of the values of that particular society.
And if he was taught all those things including those you enumerated, it means that he interacted with his parents very much. thus these values were passed on to him.
You might say his parents died when he was really young, thus those values weren't fully transferred. But it was noted that he had "hygiene" which is only appreciated at later stages of life. And it was said that he isn't a savage... thus, he had inklings of civilization.
Now let's talk about the city.
For sure, he would be placed in a city where his language is widely spoken... or at least where his parents are thought to have originated from. If he spoke Filipino, then he would have been brought to the Philippines and not Norway, right? Unless, the discoverers will use him as an experiment, which i think goes against a lot of international humanitarian laws.
Okay... now let's paint a picture of this 24 yo man.
1. He speaks the language and can interact with people to a certain extent.
2. He is in a place where his language is the vernacular which in turn has the same cultural and value sets as his.
3. He is non violent
4. He can survive on his own
Just from there, he seems to me as a "normal human being" and the fact that he doesn't have skills like city folk, does not mean he is not normal. That'd be like saying that if you're not of a certain social status, or have a certain level of education, or have physical in-capabilities then you are not normal. Also, it's like saying that if you have antisocial preferences or have Asperger's and thus be perceived as not sociable then you are not normal.
I guess to answer your question, i'd tell him in the tongue we both speak (since, if they chose me to outfit him then that must be because we understand each other), that he is normal and not listen to people who say otherwise. Then i'll take him to a rural place, and allow him to immerse himself in rural culture because putting him in a city is pretty weird considering the assumptions laid upon him. I'd hang with him and just let him do what he wants. and introduce him to people in that area... what i would have done then is allow him to use his old practices of hygiene, and food gathering, cookery, reasoning and such, while slowly being exposed to a society with more or less the same level of skills. His practices would slowly be corrected and adjusted not because he was taught so, but because he saw other people and he organically decides that their way is better. This is basically societalization... but the society being taken over is that of the man... and his begins to be part of a whole other society. And we can have this go on and on until he is societalized into the big city society. But only if, he allows himself to be assimilated further. It is up to him.
I will help him reach his preferred social potential but not dictate how it should be.
Again he is normal to begin with anyway...
my cheap two cents.
