The qualia in “Tintern Abbey” serve as a vehicle that helps Wordsworth remember a childhood account. The entire experience of revisiting the Banks of Wye makes him triggers the joyful memory of his past visit when he was younger and the impact of that visit.
The entire account allowed Wordsworth to look back upon and take pleasure in a childhood memory that he found particularly enjoyable and that triggered the emotion of happiness. He experienced mixed feeling when expressing the memory about his reaction to the sounds of the cataract. He describes that experience as
The sounding cataract
Haunted me like a passion: the tall rock,
The mountain, and the deep and gloomy wood,
Their colours and their forms, were then to me
An appetite; a feeling and a love (Wordsworth 76-80)
With regard to the “sounding cataract,” he seems to experience a quale that produces a rather negative feeling. The poem says it “haunted me,” but it also says that there is a kind a passion and it provides “a feeling and a love.” Based on this description, it seems as if despite the negativity of the haunting effect of the sounds of the cataract, the overall experience is much more positive, overriding the negative haunting of the sound.
However, overall the experience he remembered projected how much he allowed nature to lead his life, how much nature was a part of it and how much he loved nature. As it says in the poem “wherever nature led”, he was letting nature choose his course (Wordsworth 70).
The qualia are of great enjoyment and happiness during his revisit. In addition, the quale of the revisit opened the doors for him to appreciate, remember and recall the wonders and joyfulness he used to experience at the Banks of Wye with the vehicle of qualia acting as the means to access these emotions and trigger them to be remembered.
