Abstract Kant assents to Leibniz’s claim that purely positive concepts cannot contradict each other. Albeit counter-intuitive, this claim is well-grounded in Kant’s views on contradiction and conceptual content. First, according to Kant, a contradiction only occurs if a predicate is affirmed and negated; second, all concepts except of those that pertain to God covertly contain negative marks. Although I shall argue that Kant’s account fails, it is still interesting in that it tackles an overlooked problem, namely how implicit contradictions are possible.

康德论矛盾，概念内容和现实世界

摘要康德同意莱布尼兹的说法，即纯粹积极的概念不能相互矛盾。尽管有悖常理，但这种主张在康德关于矛盾和概念内容的观点中是有充分根据的。首先，根据康德的说法，只有在谓词被肯定和否定的情况下才会发生矛盾。第二，除与上帝有关的概念外，所有概念都暗含负面标记。尽管我会说康德的叙述失败了，但它仍然解决了一个被忽视的问题，即隐含矛盾如何发生，仍然是一个有趣的问题。
