Thomas Cranmer was the Archbishop of Canterbury during Henry the VIII's reign. He saw a lot of craziness from the king of his time but he also saw a lot of craziness from the schism in the Church that has come to be called the "Reformation."
Ever a student of his surroundings, Cranmer noted much about the human condition that recent Psychology and Behavioral Economics has come to ratify. Cranmer's anthropology is perhaps best summed up by the Cranmer specialist, Ashley Null, who stated it this way: “What the heart loves, the will chooses, and the mind justifies.”
As products of the "enlightenment" we like to think that we make rational decisions and that our decisions are guided by reason and understanding the facts of the matter. We hang our hat on the idea that if we could just get the other side to see the facts and use their reason, they too would see as we see. If only liberals could see the silliness of their desire for a greater national government! If only conservatives could see the irrationality of their position!
Cranmer understood that our mind is not doing the choosing. It is our heart and our gut. We use our mind to only justify our already desired choice. Much of our desire to "learn the issues" is the work to discover the "flaw" in the others position and to reinforce our previously held position. Open your heart and you will see where your decisions will take you. Perhaps more importantly, look at the heart of another and see that they too are just like you, just trying to choose and justify the longing of their heart.
Go easy on one another.
