"Osler became a 'despairing optimist' after World War I, in which he lost his son. He closed his last public address, given in May 1919 on “The Old Humanities and the New Science,” with the hope that through the Hippocratic combination of philanthropia (love of humanity) and philotechnia (love of science and technology), humankind might somehow find the wisdom (philosophia) to survive and flourish. Those words became his valedictory, as he died later that year from complications of pneumonia" (Charles S. Bryan).
