I am working on a fictional book which would be similar to that of Winnie-the-Pooh in terms of its format and ability to be read, but I want there to be philosophical meaning to what goes on in the book. My problem is that I will be using some fairly unique, -- or at least attributable -- ideas from philosophers.
One such example is one of the characters having "bad faith". I wouldn't include direct quotes from Sartre, but the idea of "bad faith" will be quite thinly veiled. Anyone who would read it that knows about Sartre would probably see some pretty clear connections. My question is whether I need to cite my sources for the idea of bad faith or not, since I'm not going to include any quotes from him.
The reason I don't want to cite the source of using his philosophy would be that I think it would take away from the story for you if you were reading and then all of the sudden see a parenthetical citation or footnote. Would it best to just include his name in acknowledgements or in some other type of recognition after or before the book itself?
