I have a question about the course of this morning, indeed, at a time Pr.camus speaks of the singular dimension of the meeting with the patient (which is a notion that is ca). However, I have not quite understood what he meant by that ... 

Can you explain this notion and give examples illustrating this concept please! 

Any help will be apprecited.

I didn't find the right solution from the Internet.
