Translation of 立方固奇，而立论甚正 I want to translate 立方固奇，而立论甚正.
It is a metaphor used in a taoist context.
I think I caught the drift but I am seeking confirmation by a sinologist or a Chinese person.
In my opinion, a possible translation would be :

"Some things look odd, yet they work well".

(Translation of  立方固奇，而立论甚正: "Cubes may look odd, yet they are upright."...)
Thanks in advance for your input !
This is a criticism from 金以谋 to 陈士铎, both are doctor of traditional Chinese medicine.
