“If, as I believe, primary care provides the essential underpinning
for any rationally balanced health service why do so many in positions
of academic power and influence have a negative opinion of general practitioners
and family physicians? In my view, this negativity is because primary
care investigators, as opposed to their biomedical colleagues, have
contributed little fundamental knowledge on the origins and natural
history of disease.”

“When a physician makes observations and records his experience
he not only adds to our body of knowledge, he also increases his self-knowledge.
The experience which he analyzes will never be the same to him as it
was before. The discipline of having to define certain terms and concepts
will mean that these terms and concepts will forever after have a new
and more exact meaning. The discipline of having to make exact and careful
observations will make his observations of all things more exact. The
need to think precisely and logically about a problem will make him
less open to deception, less prey to the fallacies that pervade medicine,
and less liable to self deception.”
