Part 3/8:
Second, Hume emphasized that causation is not something we perceive directly in the same manner that we perceive colors or sounds. While we can observe the breaking of a window when a ball hits it, we cannot perceive the intrinsic necessity that one event must cause another. Hume suggested that this notion of necessity is a mental construct we impose on the world. For example, when observing a baseball hurtling toward a window, one develops an expectation that the window will break. This expectation is born from experience and habit rather than an inherent property of the events themselves.
