托马斯·马尔萨斯《人口论》· An Essay on the Principle of Population · 投资

But to make the argument more general and less interrupted by the partial views of emigration, let us take the whole earth, instead of one spot, and suppose that the restraints to population were universally removed. If the subsistence for man that the earth affords was to be increased every twenty-five years by a quantity equal to what the whole world at present produces, this would allow the power of production in the earth to be absolutely unlimited, and its ratio of increase much greater than we can conceive that any possible exertions of mankind could make it.

白话

马尔萨斯为了更普遍地论证,把视野从局部移民扩大到整个地球,假设人口限制被完全取消。如果地球能供养人的生活资料每二十五年增加的量等于目前全世界的总产量,那就等于说地球的生产力绝对无限,增长率远超人类努力所能达到的程度。核心是:即使假设土地生产力无限增长,人口增长仍会更快。这提醒我们,不要幻想技术能一劳永逸解决资源问题,要同时管理人口和消费。

上下文

马尔萨斯在《人口论》中构建思想实验,反驳无限增长的可能性。

今日一问

如果技术能让粮食每25年翻倍,人口增长会不会仍然超过它?
