In Charles Darwin’s, On the Origin of Species By Natural Selection, it states; “…a plant on the edge of a desert is said to struggle for life against the drought, though more properly it should be said to be dependent on the moisture.” This quote is explaining the different perspectives when looking at life. Some would say a desert plant struggles for life in a drought while others would say that desert plants are dependent on moisture. This quote reminded me of Catherine and Heathcliff’s relationship in the novel Wuthering Heights by Emily Bronte. In a way, Catherine can be compared to the plant Darwin talks about in the quote stated prior. Without Heathcliff in her life she is like a desert plant, struggling against the drought. Like a plant is dependent on receiving moisture to stay alive, Catherine is dependent on Heathcliff’s love to keep her alive. There is one point in the novel when Catherine is talking to Nelly about Heathcliff and she says “Nelly, I am Heathcliff! He’s always, always in my mind: not as a pleasure, any more than I am always a pleasure to myself, but as my own being.” No matter how hard Catherine tries not to be depend on Heathcliff he is such a big part of her life that it’s almost like she needs him in order to survive in this world. This is also true for Heathcliff as we see how much Catherine’s death affected Heathcliff as a person. After Catherine died, a piece of Heathcliff died along with her. It wasn’t until Heathcliff’s own death that he was finally able to be at piece again, knowing that he would be reunited with his love Catherine.
