Thank you very much, Mr. Chairman.
Thank you to the witnesses for coming today.
As I was listening to your opening remarks, I was thinking of you, especially, Mr. Russell. I studied physics up to university and the most interesting anecdote I remember is that Heisenberg's uncertainty principle, with respect to quantum physics, was the subject of a vote in the Solvay Congress of 1927. The great Albert Einstein was on the losing side.
When we're talking about how we represent and how we understand the world, it may not always be easy to decide from a physics perspective, and no doubt that is even truer for medicine and psychology, as you stated. One should expect certain interpretations, and certain established diagnoses, to evolve, would you agree?
