Final answer:
The question focuses on English literature, examining themes of love, mortality, and the complexities of human emotions through literary devices and natural imagery in poetry and plays.
Step-by-step explanation:
The passages presented in the question evoke complex themes and utilize literary devices common in English literature, particularly poetry and plays. The use of paradox, such as 'O brawling love, O loving hate' and 'Feather of lead', exemplifies the contradiction often found in the human experience of love.
Moreover, the exploration of mortality and the notion that 'Love is better than Life' speaks to the universal contemplation of love's power over the human condition. The references to natural imagery, the transient nature of life, and the enigma of death and separation, as seen in expressions like 'the sobbing liquid of life' and 'ever the trestles of death', suggest a deep reflection on the emotional spectrum that accompanies human relationships and the inevitable parting that comes with death.
The subjects covered in these quotes mainly come from a collection of renowned works by various authors, including William Shakespeare and Edgar Allan Poe, and touch upon themes of love, mortality, and the bittersweet nature of human existence.
