There are no experts in magic, it’s just that some people have been doing it for longer than others. When we run into people who are speaking (or writing) authoritatively about some aspect of magic, it’s easier to nod wisely rather than saying, “What the hell are you on about?” Or, “Could you explain this in more detail?” Ask people questions, be naïve, seek clarification and don’t hesitate to put your own point of view across.
