Tolkien himself had a different point of view. In his opinion, if suspension of disbelief becomes necessary, it's a sign that the writer has failed. He preferred "secondary belief" instead. The idea was that the reader should remain immersed in the fictional world, confident that the world works consistently according to its internal logic. That the logic is there, even if the reader doesn't know it, and that the writer doesn't break it for their own convenience.
