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.
