Since the OP’s been answered I’ll ponder, ‘Why did I think Stephen Hawking had died this past year?’ I’d have almost sworn to it.
This sentence from the article about his refusal is a bit ironic (bolding and other emphasis mine):
I can understand disliking hereditary nobility titles such as Duke or Marquis, but a dubbing- just as a Ph.D.- being earned, I wonder what his problem is.
Albert Finney was asked about his refusal of a knighting on an interview show a few years ago- went off about it.
Just a WAG: Some people don’t like titles at all – even ones that have been earned – because it implies the Titled person has greater ‘value’ than the Untitled person.
Compare someone that has their PhD in Physics with someone else that is a few months away from attaining the same PhD. The title implies the first person is a greater Physicist, however, their accomplishments might reflect the opposite.
Likewise compare someone with a PhD in Physics with someone else equally accomplished in a different field – but a field that does not use titles. Again the title implies greater accomplishment.
I have no idea if this is Hawking’s logic; just an example of one type of reasoning. Obviously, the more you have earned a title of distinction, the less you need it. Perhaps it is just as simple as that.
Well, that’s not him referring to himself as professor, but the journalist. However, there is a big difference between titles like Professor and titles like Sir; the former depends on many years of high-level study, lecturing and research (only a few university lecturers are professors in the UK - the title’s not applied to any old PhD who works in a university), while the latter can be given to someone just for knowing the right people in business or singing a couple of successful songs.
Some possibilities, he may not support the monarchy itself (as a mechanism within a democratic system), also he may support the monarchy in principle but not want to support a system that has at its powerful head the House of Lords – an unelected chamber.
More commonplace, and likely imo, is that he may view it as political in so much as the Queen heads a societal system in which privilege creates inequality, a system that perpetuates and furthers a class system in which one group benefits greatly at the expense of others – ‘expense’ in the sense of life opportunity and other advantage.
Some might argue that a society that uses capitalism merely as a tool to generate wealth – not even a society like the USA in which ‘capitalism’ is effectively the purpose of the society – creates enough advantage without the need for the Head of State to contribute still further. But to do so does, of course, allow that Head of State to further ingrain within the pillars of that society by the mere fact of bestowing honours.
