What does Catherine mean by saying "I am Heathcliff. He is always in my mind, not as a pleaure any more than I am always a pleasure to myself..."
Catherine's quote, "I am Heathcliff" in Wuthering Heights by Emily Bronte is used to define not only the relationship of the characters, but also the relationship's effect on Catherine. Catherine is making a claim that is less about Heathcliff and more about herself.
By claiming this, Catherine is saying that Heathcliff is ever-present in her thoughts and feelings. He is a part of her in that she has inadvertently given part of her own existence over to him because of the power her feelings toward him have over her. It is a testament to the strength and depth of their relationship.
"I am Heathcliff. He is always in my mind, not as a pleaure any more than I am always a pleasure to myself..."
What Catherine is trying to say is that Heathcliff and herself are one soul, one person, they basically are on of each other. The way she thinks of Heathcliff is not the same way if someone thought about a loved one and they're great qualities. For Catherine it is more like the thought of Heathcliff is no different than if she were to compliment to herself. We all know how self absorbed Catherine can be so her saying something like this means that she loves Heathcliff as much as she loves herself which is a lot haha.
