Final answer:
The speaker in 'A Psalm of Life' views that people should live with purpose, taking responsible actions and contributing positively to society, while also respecting and living in harmony with nature.
Step-by-step explanation:
The speaker in A Psalm of Life believes that people should act in life with a sense of duty and action, striving for moral rectitude and social responsibility. This view advocates for living in accord with one's values and contributing positively to the world, which aligns with the lessons conveyed by various figures and philosophies.
Such as King David's depiction as a just ruler, Emerson's emphasis on modesty and moral life, and the realization that a good life involves a commitment to action as found in the representation of the Eightfold Path. The notion is summed up by the idea that life should be lived actively, with every action reflecting a commitment to truth, and societal well-being, much like the Christological interpretations of the Psalms.
