To what extent can an idea be unique?
Are all ideas just the combination of known principles or trial and error? Examples and peronal experiences are good as well as just opinions. This question could be expanded to any thought at all, not just ideas. If there is a thought that is almost entirely unique, there can't be any previous oppposite idea. What I mean is if an idea is the exact opposite of another it isn't really original. It just stated the opposite. If an entirely original idea can be made, how will it be formed?
I have some opinions currently, but I'm sure they'll change after your comments. Please ask me to expand or clarify if needed.
