Chapter 3: The Liaison of Ideas It is obvious that there is a principle of connection between the various thoughts or ideas of the human heart, and that they lead to each other in a certain order and rule when they appear in memory or imagination. This is most easily seen in our more serious thoughts or talk, so that if any particular thought breaks into the regular path or chain of ideas, it is immediately noticed and rejected. It seems to me that there are only three principles of connection between ideas, namely, Re-semblance, ContiguityinTimeorPlace, and Cause or Effect.
