Q: Is asking questions good or bad?
A: Neither: it depends on the reason for asking.
Are we questioning from belief, or from skepticism?
But in mainstream public discourse nowadays, most question-asking is skeptical, and it is bad - because it is motivated by pride.
The skeptical self is unquestioned: to question is to hold others to account.
Modern skeptical questioning has become a lifestyle - people get locked-into a stance of going through the world, assuming their own rightness, holding to account other people and different ideas; and this state may persist for decades, for their whole lives...
And it is all-but impossible to escape-from or eradicate this state, once fully-established.
A habit of skepticism applied to the non-self becomes the structuring principle of life.
This is the supreme, invincible arrogance of modernity.
As C.S Lewis pointed-out, modern skeptical atheism is incorrigable precisely because it put God in the dock and judges God by the standard of modern man - naturally, intrinsically, inevitably then God will be and is found deficient: He fails to provide satisfactory answers on interrogation.
I can perceive that the skeptical and questioning stance is a reaction to the amount of nonsense and dishonesty in the world; but it is the wrong answer.
What we should do about nonsense and dishonesty is ignore them (or, if possible, detect, denounce and suppress them) - but not question them!
Why should we be concerned by the answers of idiots and liars?
The proper motivation for questioning is not from skepticism but from belief.
The essence of proper questioning happens when we question authorities that we trust, to discover more concerning that which we believe.
Ideally we should question only those whom we trust; otherwise the answers are more likely to harm than help us.
