On the other side are some ethologists who seem to be more generous-minded, who see no compelling reasons to doubt that animals in general are quite capable of real thinking and do quite a lot of it -- thinking that isn't as dense as human thinking, that is sparser because of the lack of language and the resultant lack of metaphors to help the thought along, but thinking nonetheless.

在另一方面是些显然有更宽广的胸襟的比较动物学者，他们明白没有强迫的理由怀疑总的来说动物是相当有能力真正地思考并且做许多事情－－虽然思考不是像人类思考那样密集，而且由于语言的缺乏和因此缺乏隐喻来帮助思考因而是薄弱的，但不管怎样思考着。
