So because a man sees a big bridge he can just go and build it?

Because he is an engineer just without the ability to catagorize, approach, recognize, or apply engineering?

You must have those abilities in order to utilize the train of thought and as such it is exactly that; trained thought. Not inherent. Man is curious yes and yes we do ask questions. but one needs to be taught how to effectively ask and answer those questions or all you are left with is a bunch of poppycock.

The concepts need to be actualized by that exact categorization, recognition, and application.

For if one does not have the knowledge to apply said knowledge do they in fact EVEN have said knowledge? No. Of course not.

Like I tried to say earlier but was pretty much disregarded. I have had this discussion with Theologists who would take the bible and thump you heavily upon the head IF you were to even attempt to correlate philosophy to theology. Of course they would appreciate the debate but they would smile and tell you in no uncertain words how both are completely different trains of thought.

The smartest theologist I discussed this with was a Catholic. He was devout to a "T" but accepted exterior discussions and differing ideals in the name of debate because it helped him to test his faith. Which is what he pretty much explained Theology as; a test for the enlightened. A way to further your understanding of god and how he effects your life. He also stated that the Catholics have schools exactly for the reason to teach theology to the young because it needs to be taught.
Just as philosophy needs to be taught. Just as mathematics needs to be taught. Just as any subject which educates NEEDS to be taught. Else we would all be illiterate bumpkins eking out a living farming and mumbling prayers to the sun god for good crops.
