Thinking you have a choice and making a choice are interesting notions to hold. Knowing is a different game all together. It is very nebulous around whether it is an illusion, or whether we can actively influence things.

We can all ideate things, or use the argument that I might say "purple monkey dishwasher" to the person who asks me "how am I going" today, but that isn't necessarily me expressing my free will.

I need to find a bloody definition of free will before I am totally convinced if it exists or it doesn't. The reason the topic is so important to me is I'm trying to write a fictional story about it at the moment, and I can't entirely and exactly articulate what I want the theme or the learning of it to be.

Impasse, perhaps?
