What indeed is originality.............?
Is it the same as creativity?
Is it the ability to think of something that no one has ever thought before?
I think that originality is not thinking or doing de novo things....
That is creativity.
Originality is the ability to reach a conclusion.....which might be pre-discovered or pre-invented or pre-recognized, all by yourself.
It is reaching to such conclusions independently (without help). So I may read a book where I find the proof of an equation...but only if I myself am able to follow the same route of of reasoning and reach the expected destination all by myself then and only then I will call my thinking pattern original.
