Key passages
“All the perceptions of the human mind resolve themselves into two distinct kinds, which I shall call IMPRESSIONS and IDEAS.”
Every mental content is either an impression (a vivid sensation or feeling) or an idea (a faint copy of an impression).
This foundational distinction sets the stage for empiricism.
“There is a secret tie or union among particular ideas, which makes the mind associate them together in a certain manner.”
Ideas are connected by hidden principles that lead the mind to move from one to another.
Introduces the association of ideas as a core mechanism.
