What interests me most about this is that even now we are so lacking in our understanding of the function and dysfunction of the human mind that there are not even good words, robust descriptions, or any scientific metrics or diagnostics for what is going on. Words like engagement and violence get thrown around without quantification and a parade of categories are fitted and later abandoned much like Jani's imaginary friends. It is important for us to understand what the mind is and how it is evoked from brain function, but now we are mostly helpless.
