Asking questions a "childish" way to learn, to teach? In modern world it's often regarded as "poor" if asking questions. "What, you don't know?", others would fast lower others, yet forgeting that they have been given before as well.

It is also the subtil fear to be obligated, fall into debt, that people "force" not to ask or on wrong places, wrong people and so the tendency goes in direction "steal" thinking not causing debts.

The times of google and more or lesser anonymos exchange places make it even more common that people seek, if even, for places to gain, where they believe not to accumulate debts.

It's not seldom, out of this, that "asking questions" is estimated as childish, the way "unwise" and "poor", "people of less skill" come to gain Dhamma.

What do you think, is there an adult way that replaces questioning? Is asking questions, asking for things childish?

(A maybe useful reflection that might make some parts understandable for answering the question: Giving, taking and the "new" world - "Labour makes (you) free!?")

Is asking questions, asking for things childish?

Asking question is something that children do, but adults can do it too.

If I'm working with someone and (for example because I have worked there longer) if I know more about our work than they do, or if I know something about our work that they don't know but should know, then I want them to ask me questions. I want them to have good judgement (skill) too, in deciding how much to ask and how often, I expect us to weigh and find a balance between their spending too long (too much of their own time) trying to figure everything out for themselves, when instead I could have told them easily; or on the other extreme, their asking me too many questions (taking too much of my time), instead of reading the answers for themselves.

I am not a formal teacher, teaching someone else would be a part-time job for me, and the subject (which is, knowledge of the software that I might develop with co-workers) doesn't have a specific curriculum. But in general it's good if someone asks me questions: it's easier for me (and better for everyone) if they tell me they don't know something, than for me to have to supervise them and for me to have to try to guess at what they don't know. Also I distinguish between things they ought to know already compared with things they couldn't know already.

Anyway for these kinds of reasons (i.e. my experience at work) I think it's normal for adults to ask questions.

Children do sometimes ask questions to avoid work (for example, asking questions instead of putting on their shoes to go to school). It's a bit irksome when an adult asks insincere or unnecessary, unhelpful questions ...
On this site I'm grateful that people are willing to reply to my questions. I usually try not to waste their time, and try to only ask questions which will help to me, and whose answers I can't easily discover by a little work of my own (research and reading already-existing text).
The purpose of this site isn't to be a question-factory, keeping people busy  answering endless unbeneficial questions.

What do you think, is there an adult way that replaces questioning?

At university we had lectures, with hundreds of students in the room. The lecturer would talk, students couldn't ask questions, we had books to read ... and some individual tutors/tuition, perhaps an hour a week, to talk about home-work.

Or sometimes there's learning by following (emulating) other people; or waiting to be told.



Comments on the paper you referenced in the OP.

So there was a neighbour who was hardly ever able to accept a gift, for example some fruits from the garden.

In the society I live in now I've never known anyone refuse such a (small) gift.

The benefactor, "the mother", is little by little devoured

Apparently that can happen in abusive (so-called codependent) relationships.

Everything is easier nowadays

People have been saying this kind of thing since ancient Greek and Roman times, at least: especially, saying that the younger generation is lacking in courtesy.

We cringe, usually, when we hear someone say "Labour makes (you) free"

I was amazed to read "Arbeit macht frei" as the title of the page. Because of the phrase's historical usage I consider it a phrase which "no longer means what you think it means" i.e. it has (historical) "meaning" that's not evident from its overt form. It's not the plain meaning I cringe from but the association with Auschwitz et. al., which makes it difficult for me to even consider the phrase, which evokes horror (or pity for the victims, to whom the phrase was a lie) as soon as I read it.



Anyway this was kind of a vague answer, I'm not sure whether it answered your question (because I don't understand the intent or motive behind your question).

If you refer to the suttas you can see that it's full of questions and answers: students asking question (which teachers answer), and teachers asking Socratic questions.
