When I read about how most of our thoughts are repetitive, I wondered if it would be possible for us to have a thought that is completely new or original by will. Is there some way we can have unique thoughts whenever we wish to?
Please note that this question does not focus on our brain's mental capacity or free will to be able to think of something original. You could think of it something like asking you to paint something original; I am not asking if you are even able to paint in the first place, but instead how you would paint it if you could.
Also you should ideally be able to think of something new completely by your own in your consciously aware and normal self, without relying on external factors like taking inspiration from your surroundings or words from a recent/ongoing conversations, looking at the content open in your device, using any drugs or consumables, being affected by strong emotions etc.
Edit: Elaboration in last paragraph
I think that is a linguistic question ultimately. You could take potentially utter a new sentence never before uttered even with the top 10 most used words in a language.
That is one of the most significant things about the human being. Actually I am quite surprised when people come with definitions for human nature eg. fundamentally good, fundamentally evil, homo sapiens, homo faber, etc. that the linguistic potential to turn a small set of things into infinity is often ignored. No other animal can think and speak like we do.
Not necessarily, note that I wrote, "expressed in existing ways" and not, "spoken/written in existing ways". Expression itself has a greater breadth than language alone, e.g. movement, drawing/painting, instrumental music arrangements, etc.
It includes language, absolutely, but it is not limited to language, which makes for a more challenging question imo. If not expressed in existing ways, it would meet the criteria of entirely new and unthought of, presumably, but it would also likely fail to be recognized as an expression at all.
Fair point but I think then it just expands the consideration from linguistic (which is already more than spoken or written, it also covers signed, whistled, drummed, danced, in one case I heard about -- eye movement) to semiotic.
