One Way to Ward Off Dementia
Spence's book is marvelous scholarship and SO interesting. He explains in great detail the process by which Ricci taught the Manchu elites how to perfect their individual and collective memories using the "memory palace" constructy. A modern manifestation of this same process is Tony Judt's book "The Memory Chalet." He employs the technique in recalling and summing his life as he approached death with Lou Gehrig's disease.
