What is characterized as a 'paradox'?

A paradox is a statement that seems to contradict itself or lead to a self-contradictory conclusion yet may still hold some truth or insight upon closer examination. This complexity is what distinguishes a paradox from straightforward statements or figures of speech. For example, the phrase "less is more" is a classic paradox; it suggests that simplicity can enhance an experience or understanding, even though it appears contradictory at first glance. The nature of a paradox often provokes deeper thinking and discussions, revealing layers of meaning that challenge conventional wisdom.

In contrast, the other choices describe elements that lack the complexity and depth inherent in a paradox. A simple and clear statement does not contain the self-contradictory properties associated with paradoxes, while a true statement, by definition, cannot contradict itself. Similarly, a figure of speech with no complexity cannot embody the nuanced and intricate nature that a paradox does.
