“I believe the ability to think is blessed.
If you can think about a situation, you can deal with it.
The big struggle is to keep your head clear enough to think.”

“Headology” is a word used in Terry Pratchett’s Discworld novels.
It is similar to psychology, but sort of more… practical….
“The power of Headology is not to be underestimated. Clearly, the way a person sees himself and the surrounding world forms the person's reality. If this view is changed effectively through the use of Headology then this person's reality changes. This allows witches to make people think they are frogs, for example. Witches generally think that Headology is a more powerful style of magic than any of the fancy stuff wizards use. Headology is what witching is all about. A witch needs a very powerful, focused, and trained mind to use Headology. Granny Weatherwax is the foremost practitioner of Headology on Discworld.”
