For thirty years now I have been studying my fellowmen. I do not know very much about them.

三十年来，我一直研究我人类同胞，但至今了解不多。

A large number of our fellowmen, who have grown heartily sick of the performance in which they are expected to join daily and all their lives long, are only kept from flight by one or two considerations.

我们许多同胞已经厌倦了他们被期望每和终生参演，只是出于一两个考虑才没有逃跑。
