The true essence of who we are is our unique ability to be sensible and solve problems. Two people who have carbon copy beliefs can see things in a completely different way. But, if their beliefs lead to virtue, goodness, and peace then I find that astonishing since we as human beings have struggled with this since beginning times. I'm just putting in to context how that specific ability of ours is like a God in that it can help us to become the best person we can
There are animals that use tools and solve problems. Animals certainly can be sensible. So far you've not told me what the essence of who we are is. What if a person can't solve problems and is insensible? Do they have no essence? Your comments on beliefs and essence have nothing tying them together.
