what does "to go nonlinear on me" mean?
2) what does "to take a walk on the wild side" mean? not be on the right track?
3) pls explain this sentence: "it is not intellectual justifications of my own authority".
"To take a walk on the wild side" means to do something completely out of character. For example, if you're usually a non-drinker, your friend might invite you to "take a walk on the wild side" and go to the bar (or pub) with him and have a beer or two.
