典籍中关于老子的职官,有“守藏史”、“柱下史”二说。实际上它们的内涵并不一致。“柱下史”为柱下御史的省称,乃秦汉御史属官,其主要职掌为纠察监督,并非守藏档案图书。由于后人忽略了柱下御史的沿革,并将其与东方朔所说的“柱下”、王莽设置的“柱下史”相混淆,以及汉代官制变动等原因,遂误解老子为“柱下史”。老子的职官应为“守藏史”。 The classics about Lao Tzu’s officials, there are “Shou Tibetan history ”, “column history ” two said. In fact, their connotation is not the same. “Column under the history ” for the column under the province of Censor province said, is the Qin and Han censor belongs to the officer, the main job for the picket supervision, not keeping files archive. Because later generations overlooked the history of the Censor, and confused it with Dongfang Shuo’s “Pillars” and Wang Mang’s “History of the Pillar”, as well as changes in the official system in the Han Dynasty, they misunderstood Lao Tzu For the “column history”. The officials of Lao Tzu should be “keep history”.
