By Naming Something, We Define It

In Humash, we have been studying Moshe's questions to God, right after he has discovered that he is supposed to be the savior of Bnei Yisrael. In his second question, Moshe asks God, "What is your name" and God responds that God's name is אהיה אשר אהיה- I am what I am (whatever that means!). We started talking about how naming something defines that thing and helps us understand what that thing is, and I posed the question- can we ever truly understand or know God?
