"That is really what philosophy started being about and has been about for most of 2000 years.
"Pooh addresses the same thing, but the way that the Poohisms are, they are a lot more accessible than reading ancient philosophers.
"Somehow AA Milne really managed to encapsulate the thoughts of great philosophers in really simple, direct language that people can access and understand."
Dr McCall believes the language given by Milne to his characters allow children and adults to explore complex ideas as they are reading.
"There's one [Poohism] I think is absolutely amazing, and it's so simple: 'People say nothing is impossible, but I do nothing every day," she said.
"As soon as you hear that you think about what 'nothing' means, because there are four or five meanings of 'nothing' in that little sentence, and you're thinking, 'what does impossible mean', and 'what does nothing is impossible' mean. Immediately you are thinking philosophically, whatever age you are."
Dr McCall believes the 2000-year-old ideas explored in Pooh are still vital today. "I think they will always be relevant to human beings as long as we are human, because they are deeply to do with the human condition," she said.
"Every generation needs to discover for itself how to live the good life. We think that things like technology and modern items change life dramatically, but the really important things about being human don't really change."
