It easier to copy someone s work and pass it of as yours. I agree with  Maurice Isserman

“Plagiarism is a form of fraud. You plagiarize if you present other writers’ words or ideas as your own.”

but when is it considered plagiarism, is it when the professors use the textbooks, or when a musician writes a verse, did someone else at some point use it. Academically speaking plagiarism is a big no-no, it can be avoided but at the same time, there are excerpt from articles, books, newspapers that explain what we are trying yo say. Is it plagiarism if you don’t get caught.
