"From inability to let well alone;
from too much zeal for the new and contempt for what is old;
from putting knowledge before wisdom, science before art, and
cleverness before common sense;
from treating patients as cases;
and from making the cure of the disease more grievous than the
endurance of the same, Good Lord, deliver us."

Sir Robert Hutchison, (1871-1960).
