There is no exercise of the intellect which is not, in the final analysis, useless. A philosophical doctrine begins as a plausible description of the universe; with the passage of years it becomes a mere chapter—if not a paragraph or a name—in the history of philosophy.
Thinking, analyzing, inventing are not anomalous acts; they are the normal respiration of the intelligence.
Every man should be capable of all ideas.
—Jorge Luis Borges, “Pierre Menard”
没有智力的锻炼，从根本上说，它是没有用的。哲学学说开始于对宇宙的似是而非的描述；随着岁月的流逝，在哲学史上，如果不是一段或一个名字，它就变成了一个简单的篇章。
思维、分析、发明并不是反常行为，它们是智力的正常呼吸。
每个人都应该有各种思想的能力。
- Jorge Luis Borges，“Pierre Menard”
