adj.无拇指的
"One can believe in the necessity of the opposable thumb for the development of intelligence without doubting a human capacity for thumbless thought. “人们在相信可对捏的拇指对于智能发展的必要性的同时，也不怀疑人类有进行没有拇指的思考能力。”
When we lie on our backs in an alpine meadow tucked on the perch of high mountains, or wade into the mucky waters of a tidal marsh, we are encountering the "thumbless thoughts" of nature. 当我们躺在隐于高山山梁的草甸上，或涉入潮沼肮脏的水中，就遭遇了大自然的“无拇指思想”。
