The ancient Greeks understood that there is a deep connection between truth and beauty.  From that insight one can see that trying towards truth is like a Mozartian symphony where every member of the orchestra plays his or her part. But each one needs to play his part alone --and know his place. The violinist ought not to play the part of the cello or piano. That would be as if in an army, the  person standing watch would desert his post and try to fulfill the part of a general. Even if he might be a good general in other circumstances, but still he has deserted his post [and by that cause the city to fall.]. Even on a religious scale we can see how there should be an awareness of this point. Torah has a good point --monotheism. Christians have a good point about kindness. The Torah is also right about law. Where things go wrong is when the violinist goes over to the French horn section and decides that he can play the French horn better that  those in the wind section. Or things can go wrong when one is not following the score. Or people on the outside imply try to interrupt or play music of the dark side [as most music is nowadays.] 

And in the search for truth enlightenment philosophers also played an important role. While on one hand the middle ages were aware of the need for both reason and faith, still the development of both was needed.  Even though Plato Aristotle and Plotinus had gone far in the realm of reason, still a lot was missed and there needed to be Kant to begin to resolve the mind body problem,
