I couldn't disagree more. Reality is. You can see it if you want to. But you must be objective.We do not know what reality is because we do not see the actual world we see what our limited sensory organs translate into chemical and electrical impulses that our brains give us an interpretation of.
Reality is nothing but shades of gray and human behavior is nothing but more shades of gray.
We don't really know how the brain works anymore than we know the universe and all we understand about the universe is about 5% of all the matter and energy in it.
