The positive use of philosophy, biblically speaking,
according to Colossians chapter 2, verse 8: Beware lest any man cheat you by philosophy and vain deceit: according to the tradition of men according to the elements of the world and not according to Christ.
It seems not to be within the realm said philosopher's considerations.
The Bible does speak to the matter of why it is not open to abuse by those who seek in the absence of profitable faith.
It is the glory of God to conceal the word, and the glory of kings to search out the speech.
King - as those who seek to rule their emotions per the following passage.
And we know that in all things God works for the good of those who love Him, who have been called according to His purpose.
An deepened study of the Bible gives a different answer that differs in some areas of what most Christians are willing to admit,
including how all humans became sinners.
But it was well taught by some early Church Fathers, such as Origen,
who believed in reincarnation, and that eventually it is the blood of Jesus by which all things will be redeemed.
The biblical proper use of intellect to achieve universal understanding
would be that God, again and again attempts to show how it is our own vain devices of ego, rather than the proper use of ego once facing one's own vanity and conditions of such vanity having darkened one's heart.
The proper use of human intellect would be convicted of one's guilt and repent and accept the holy spirit as that which can properly teach all things.
Ecclesiastes 7:29 (7:30)
Only this I have found, that God made man right, and he hath entangled himself with an infinity of questions.
Who is as the wise man? And who had known the resolution of the word?
The resolution begins with a renewed heart but is not completed until one matures from being a baby Christian, on the milk, to an grown with renewed mind.
For every one that is a partaker of milk is unskilful in the word of justice: for he is a little child. But strong meat is for the perfect: for them who by custom have their senses exercised to the discerning of good and evil.
Ahh, matured believers with the renewed mind tho - how rare such may be.
In my own view of present humanity, as far as I can tell,
I don't think I have come across any.
