Utopianism's main flaw is its obsession with perfection.

乌托邦主义的主要缺陷是它对完美的痴迷。

Utopianism is the ism of utopias.

乌托邦主义是乌托邦主义。

Though the open-source movement has its roots in the post-hippy utopianism of 1980s California, it is nevertheless going strong today in part because its ethos is not entirely altruistic.

尽管开源运动起源于 20 世纪 80 年代加利福尼亚州的后嬉皮士乌托邦主义，但它如今依然蓬勃发展， 部分原因是它的精神并非完全是利他主义的。

Perhaps this is why much discussion of the topic is now confined to utopianism's dark side - dystopianism, a way of describing worlds, real or imaginary, in entirely negative terms.

也许这就是为什么现在很多关于这个话题的讨论都局限于乌托邦主义的阴暗面——反乌托邦主义，一种以完全消极的方式描述世界的方式，无论是真实的还是想象的。
