“老子”公案自古至今，到二十世纪初“古史辨”派再度为此引发了数十年的激烈争辩。七十年代帛书《老子》、九十年代竹简《老子》的发现，令汉语学界一片兴奋，　皆以为“老子”公案可以就此了结。本文经过冷静的分析与检讨，得出了不同的结论，即，　就我们现有的材料，尚不足以了结“老子”公案。因此我们还需要等待新的发现、新的证据。 Since ancient times, the “Lao Tzu” case has caused intense debates over the past decades by the “ancient history discrimination” school in the early twentieth century. The discovery of the silk book “Lao Tzu” in the 1970s and “Lao Tzu” in the bamboo slips of the 1990s brought an excitement to the Chinese academic community, all of whom considered the “Lao Tzu” case to come to an end. After a calm analysis and review, this article draws a different conclusion that, with our existing materials, it is not enough to conclude the “Lao Zi” case. So we also need to wait for new discoveries, new evidence.
