The more you get to know, the more you realise that you know very little, I have found ! But now my mind is open to all ideas, I find learning a real pleasure !
My mind is not so open that my brain fell out, so I Fact Check, check the sources and Authorities of Scholars who are referenced, even if I am studying a seemingly good Paper or Book, that is presented as Academics do, I found a Paper a while ago, it looked very learned and seemed to make some sense, but the "Authorities" appealed to all turned out to be of the same "school" of thought, suspicious that ! Academic Books do that too.
So be careful, use Critical Thinking skills, and the above checks, and a wealth of knowledge that is trustworthy is out there !
