托马斯·马尔萨斯《人口论》· An Essay on the Principle of Population · 投资
As the necessity of sleep seems rather to depend upon the body than the mind, it does not appear how the improvement of the mind can tend very greatly to supersede this 'conspicuous infirmity'. A man who by great excitements on his mind is able to pass two or three nights without sleep, proportionably exhausts the vigour of his body, and this diminution of health and strength will soon disturb the operations of his understanding, so that by these great efforts he appears to have made no real progress whatever in superseding the necessity of this species of rest.

白话
睡眠的必要性主要来自身体而非心灵,所以靠提升心智来取代睡眠这种“明显弱点”恐怕行不通。一个人若因精神高度兴奋而连续两三夜不睡,身体精力就会相应透支;健康与力量下降后,理解力也会很快受干扰。结果,他这些巨大努力看似没有真正推进“免去睡眠”这件事。换句话说,心智活动再强,也不能替代身体休息;硬撑只会让身心一起受损。可执行的做法是:别把少睡当成本事,把睡眠当作维持心智效率的基础条件,优先保证规律休息。
上下文
马尔萨斯《人口论》讨论人口与自然限制,此处借睡眠说明身体条件对心智的约束。
今日一问
我是否曾把熬夜硬撑误当成效率,而忽略了身体对心智的支撑?
