Can Reason Really Discern Complex Realities?

I know I need to turn back to giving a few assessments of the recent SVTQ issue, but I hope you will pardon the last post and this one as well.  I stumbled across this article recently:

As one who has been granted the opportunity to teach information ethics the last several semesters (though the adjunct work ends after this semester 🙁 )  I have begun paying a little more attention to the history of technology (in addition to church and religious history).  I must say, for as amazing as computer technology has been from the 1970s onward, I am the most amazed at older mechanical calculators and this ancient device is, I think, downright astounding!  Here we have an astronomic calculator on par with the mechanical clocks developed a thousand years later.  I find that very intriguing.

It also brought to mind just how vitally important reason is within Christianity.  If reason can be used to discern complex realities, then reason must be employed within theological discourse.  I am aware that Orthodoxy teaches we cannot fully know God.  I am also quite aware that God is “being,” is not part of the created order, and therefore cannot be analyzed by the scientific method.  Yet, I also know that reason must play a vital role in how we love God, for Jesus said to love God with all our minds as well, not just our hearts and souls.  And that is where reason plays a role.  Reason can be employed to help us discern God’s actions within the world, through the world.  Reason can help us in our explanations and defense of the faith.  Reason can help us determine how to relate to fellow Orthodox Christians, fellow Christians, and non-Christians of all sorts.  Reason is, to put it simply, amazing, when it is turned in the right directions (for if misguided, it can lead to things such as atheism, bigotry, and holocaust–which is not to claim that these three are always found together).  I think when reason works correctly, it is even hard to tell where faith ends and reason begins.
