How does Kant define the relationship between existence and predicates?

Kant believes that existence does not add to the concept of an object itself; rather, it signifies the affirmation that an object is found in reality. He argues that existence is not a predicate that can be added like other qualities or attributes. Thus, when we consider the nature of a concept, existence does not contribute any value to it; the predicates alone contain the conceptual understanding, and adding "exists" does not enhance our comprehension of the concept itself.

In this view, existence functions differently than the other attributes; rather than modifying the concept, it simply indicates whether the concept has a counterpart in the physical world. Therefore, the claim that existence is irrelevant to conceptual understanding aligns with Kant's philosophy, which posits that existence is not a characteristic that can be inherently included in the predicates of a concept.
