I don&#x27;t think that&#x27;s a meaningful question.  One could go back a couple of centuries, before germ and virus theory was developed, and ask the same thing about physical illnesses.<p>It would be more accurate IMO to say that we&#x27;re getting a better understanding of traits and characteristics of the human mind, some of which we currently have reason to believe are disorders, and are getting better at detecting those traits&#x2F;characteristics.
