    人类的智慧与大自然的智慧相比实在是相形见绌。无论是令人厌恶的苍蝇蚊子，还是美丽可人的鲜花绿草；无论是高深莫测的星空，还是不值一提的灰尘，都是大自然精巧绝伦的艺术品，展示出大自然深邃、高超的智慧。大自然用“死”的物质创造了这样丰富多彩的生命，而人类却不能制造出一个哪怕是最简单的生物。就目前所知，人本身就是自然智慧的最高体现，是她最杰出的作品之一。人体共有一万多亿个细胞，这么多的细胞不仅能够相互协调，而且不同细胞都有着与众不同的特殊分工，都有其特定的工作，绝对不会混淆，从而使整个人体处于高度有序的状态。在近百年的时间中，人体细胞尽管更替许多次，但这种秩序并不会改变。最不可思议的恐怕要数我们的大脑了，它使人有喜怒哀乐，能够思维，能够理解、想象。大自然也很“懂得”美学原则，在创造各种物质以至人体的时候运用了各种美的规律，比如对称性、协调性等等，使人体、花朵等表现出难以形容的美。要造出这样的一个人来，让一万亿个细胞协调工作，是人类的智慧所不能胜任的。
