science and technology Writing Medicine By jamanetwork.com Published On :: Tue, 05 May 2020 00:00:00 GMT My first glimpse into the craft of physician-writers did not come through Anton Chekhov, Walker Percy, or William Carlos Williams, whose works I only came to after medical school. As a schoolboy, I loved W. Somerset Maugham, although he never practiced medicine, and his craft had little to do with his medical degree. My introduction to physicians as writers came through my textbooks. Boyd’s Pathology made me aware of literary voice, the ability of authors to place themselves in the text, let their personality come through, and subtly become a character in the reading experience. On the topic of defining the moment of death, Boyd in his single-author text wrote, “It was the author of the book of Ecclesiastes who said, ‘There is a time to be born, and a time to die.’ Fortunately it is the clinician, not the pathologist, who has to make this difficult decision. Sometimes, however, the kindly doctor may find himself murmuring those moving lines from the last act of King Lear: O let him pass! He hates him/That would upon the rack of this tough world/Stretch him out longer.” Full Article

science and technology For the Peace of Your Mind By jamanetwork.com Published On :: Tue, 05 May 2020 00:00:00 GMT We hasten to assure our readers that a piece of my mind...is not intended as a sounding board for peevish gripes, nit-picking beefs, or sundry assortments of righteous indignation, which are usually prefaced by an angry “let me give you a piece of my mind.” Nor is this section of The Journal meant to be a podium for pompous preachments and ex cathedra pronouncements. Nor again is it designed to be a forum for half-baked speculations and warmed-over hypotheses. Least of all is a piece of my mind envisaged as a jamboree of jokes and a shivaree of limericks.
