Brian Head is a pseudonym.
There was once a cricketer called Brian Brain, of whom a friend said: “Brain by name, Brian by nature”. If the pseudonym needs explaining further to you, adieu.
The creator of this site has several other pseudonyms, but revealing them would be counter-productive. After all, the key function of pseudonyms is anonymity, which becomes ever-more necessary in an online world.
But there is more than privacy to a pseudonym.
A common error in certain strands of critical thinking and public perceptions is called, by some, The Authorial Fallacy. This is the mistake of reading the creator’s personal life into their art. Of course, sometimes artists draw on their personal life for material, but ideas are also lifted from books or something a friend has told them or [etc]. And then all things go through a transformation and come out quite different to any meaning in the original context, to serve the purpose of each artistic work. Something from personal life can be used to say something completely unrelated to the person and, inversely, something completely unrelated to the person can be used to say something quite personal.
It is not the creator but the creation that matters.
