>PRESENTATION:
“I embarked on research rather late in life, obtaining my PhD at the age of 45. Since then I have published work on the joint measurement problem, Bohmian mechanics, Contextuality, Probability, and SIC-POVMs. I earn my living as a high school teacher. I am a senior visiting fellow at Queen Mary, University of London.”

In the first part of the talk I will argue that the Bayesian point of view is correct in so far as a probability should be seen as a logical construct, not a physically real entity. In particular, the quantum state should be seen as a logical construct, not a physically real entity.
In the second part of the talk I will criticize the position of most Bayesians, that a probability represents a state of belief.
My tentative conclusion will be that a probability is neither a physical entity out there in the world, nor a subjective entity inside one's head.
