It is of my opinion that both philosophies are equally valid, yet serve entirely different purposes. We experience, or understand G-d, through the ten constrictions which He passed through in creating the world. These constrictions each respectfully gave way to ten refractions emanating from the source. The first three attributes are the intellectual attributes, and the last seven are the emotive oneness.
Different attributes dominate, however, in different individuals.
In the non-Jewish soul, it is the seven emotive attributes. This is why the number three dominates in so many aspects of Jewish thought. Similarly, the number 7 plays an important factor when studying the non-Jewish role in creation. The number three is a unifying number. When two opinions appear to contradict one another in the Talmud, a third one comes in and reveals a deeper level, demonstrating how indeed the two original opinions did not contradict one another to begin with, there was just something which had been overlooked.
