《老子》思想源自《周易》古经吗?

Was the ideology of Lao-zi originated from the ancient Text or Zhouyi?

《老子》五千言的思想源自殷易《坤乾》（即《归藏》，不是源自《周易》。理由有三：一、《老子》书 中不见首乾次坤的思想，倒是首坤的思想明显居多；二《老子》的辩证思维模式属于与《周易》古经不同的 另一类；三、关于宇宙生成问题，《老子》的主张也与《周易》古经不是一路。

This paper points out that the ideology of Lao-zi was originated from Guicang but not from Zhouyi. The author states three evidences for his viewpoints: at first, there are more aspects putting the hexagram of Kun (《坤》) in the first Place while Putting Qian (《乾》) in the second place (which follows the order of hexagrams' order of Guicang) in Lao-zi, but not in turn (which is in conformity with the hexagrams' order in Zhouyi). Secondly, Lao-zi's dialectical thinking mode-belongs to a mode different from that of the ancient Text of Thouyi. And thirdly, Lao-zi's view on the universe's generating & producing differs from that of Zhouyi's ancient Text too.
