Kind of an interesting question to ask. Last time I checked, our minds are the same as we are, which means the question should be: how do I keep from plagiarizing?
Well, that’s simple, do not use someone else’s work as your own. I try to link of use the share button for what I use here. It’s that’s not available..then I post the writer’s name along with the article. That lets everyone know that I’m not trying to pass off someone’s work as one of my own. Now, when writing fiction it tends to be a bit more difficult.
As a lot of people have said before, ideas aren’t protected. Now, how you go about expressing that idea..now that’s a different story. The best way around the issue is to not do it in the first place.
