From a Navy News article:
"Professionals from all fields must maintain their level of knowledge and development to preserve their social trust", said Cook.
"When you go to a doctor, you expect them to be reading medical journals; when you go to a lawyer, you expect them to be keeping current on the state of their profession," said Cook.
"The same is expected from military leaders."
"For most Navy people this is a relatively new concept, they don't really think of themselves in these terms. They use the term professional, but that usually means that they are competent," he added.
During her remarks, RADM Peg Klein underscored Cook's point.
Dr. Cook must be thinking about some other Navy. I don't believe the Sailors I served with thought that "professional" meant you were merely competent. I must be missing his context. I don't know many in the Navy who believe that they don't have to keep current on the state of their profession. Dr. Cook may need to get back out to the Fleet.
