可道，非常道；名，可名，非常名。 无 名天地之始；有，名万物之母。 常无，欲以观其妙 常有，欲以观其徼。 此两者 同出而异名 同谓之玄，玄之又玄，众妙之门。 -辜正坤、任继愈
英译评析 道可道，非常道；名可名，非常名。 The Tao that can be trodden, is not the enduring and unchanging Tao. The name that can be named, is not the enduring and unchanging name. tread(trod,trodden):walk 可道”≠can be trodden;应是：can be utterable/said/told 常，恒久；长久不变[constant,fixed;invariable;eternal;unvarying]
无名，天地之始；有名，万物之母。 (Conceived of as)having no name,it is the Originator of heaven and earth; (conceived of as)having a name,it is the Mother of all things. 辜正坤： 无，名天地之始；有，名万物之母 The Nothingness is the name of the beginning of heaven and earth; The Being is the name of the mother of all things
故常无欲，以观其妙；常有欲，以观其徼。 Always without desire we must be found, If its deep mystery we would sound; But if desire always within us be, Its outer fringe is all that we shall see. 英译虽然朗朗上口，但意义难明！ 问题(1)“有欲”、“无欲”与整个文义不合 (2)“以”：用？“其”：指代？ 辜正坤 故常无，欲以观其妙；常有，欲以观其徼。 Hence one should gain a insight into the beginning of the Tao by constantly observing the Nothingness; And should perceived the end of the Tao by constantly observing the Being
此两者同，出而异名。 同谓之玄，玄之又玄，众妙之门。 Under these two aspects,it is really the same; but as development takes place,it receives the different names. Together we call them the Mystery. Where the Mystery is the deepest is the gate of all that is subtle and wonderful. 玄：神妙难捉摸，深奥[mystic;profound;abstruse] 问题：“常有”、“常无”怎么会“同”？
