Causality refers to the way our minds interpret and organize events to understand their relationships and significance. It helps to create a coherent narrative from seemingly random occurrences, allowing us to grasp the reasons behind actions and outcomes. This mental framework is essential for making sense of complex situations and historical developments.

In Walter Isaacson's "Kissinger: A Biography," the author illustrates how this concept applies to Henry Kissinger's life and career. By analyzing the connections between his decisions and global events, we see how causality shapes our perceptions of his legacy and the world around us.
