No sensible person will deny that the works of Nature are in the highest degree simple, necessary and as economical as possible. Therefore machines devised by mankind will doubtlessly likewise attain most success if they are as far as possible modelled on works of Nature.
任何明智的人都不会否认，大自然的杰作在最大程度上是简单的、必要的，而且是尽可能经济实惠的。因此，如果人类设计的机器尽可能地模仿自然，它们无疑也会获得最大的成功。
