We reflect to solve problems. To solve the problem, you have to know what the problem really is. But to know what the problem is, you have to know what questioning is. A question is a system of ideas that is trying to fix a problem in its own structure. Questioning clarifies the problem to figure out how to solve it. Once the system of ideas is as complete as we can make it, we can construct theories. The more complete the system, the more the solution is better, easier, and faster. Wording the question well is part of the process of answering it.
Very few can or do truly think. Many minds wander from the subject in hopeless reverie or they just get bored. They can't think about ideas. They may be tired or distracted or just not interested. Or they may be over-emotional. They might be insane, or just plain wierd. These things we pass by. They distort and disrupt by breaking in from the outside.They have an importance, and some thinking is at the mercy of those factors.
But thinking can can never surrender itself completely to the control of the subject-matter and it can be objectively logical, even though it can be influenced by instincts, desires, and feelings. If that were not the case, one could not know that fact, much less state it. If all thinking is governed by non-logical factors, then that statement itself is also governed by those non-logical factors, and that statement has no more claim on our acceptance than any other non-logical factor. If we can't solve a problem, it's because of a lack of knowledge or lack of creativity or the will to inquire.
