Final answer:
It is not possible to determine Leah's attitude towards her father with the provided information. More details are required from the book to understand her feelings. For the universal emotions, 'melancholy' is not one of the seven as listed by researchers.
Step-by-step explanation:
Without additional context about the book and Leah's relationship with her father at the start, it is difficult to conclude which attitude Leah specifically has toward her father. The sentence provided, 'he could not entirely forget it, and unconsciously manifested, in his intercourse with his son, some of the poor man's deference toward the wealthy and well-born,' suggests there might be a dynamic of respect or perhaps a self-conscious deference from the father's side, but it does not directly indicate Leah's feelings. To accurately answer the question about Leah's attitude toward her father, more information about their interactions or Leah's thoughts and feelings at the beginning of the book is needed.
In regard to the second part of your question about the seven universal emotions, based on psychological research, the emotion of 'melancholy' is not listed as one of the seven universal emotions. The universal emotions typically referenced include happiness, sadness, fear, disgust, anger, surprise, and contempt.
