follies

the follies of youth.

青年人傻事。

regretted the follies of his youth.

为他年轻时愚蠢行为而后悔

the follies and whim-whams of the metropolis.

大都市荒唐事和怪念头。

My reconcilement to the kind in general might not be so difficult, if they would be content with those vices and follies only which nature has entitled them to.

如果“野猢”这个种族满足于大自然赋予他们那些罪恶与愚蠢，我同它们和解就不会太困难。
