Final answer:
The speaker of the provided quote cannot be identified with certainty from the given excerpts. The quote discusses themes of servitude and authority and aligns with concepts of the divine right of kings or natural political order, but the exact source is not provided.
Step-by-step explanation:
The speaker of the quote "Unjustly thou deprav'st it with the name / Of servitude to serve whom God ordains, / Or Nature; God and Nature bid the same, / When he who rules is worthiest, and excels / Them whom he governs." is not directly identifiable from the provided excerpts alone. This quote appears to present an argument about the natural order of leadership and service, suggesting a view that servitude to a worthy ruler, as ordained by God or Nature, is not an injustice. This perspective is in line with arguments regarding authority and governance, which can be found within the realms of philosophy and literature concerning monarchical rule or the divine right of kings.
Without additional context or a recognizable source, we cannot definitively name the speaker of the specific quote. The sentiments echo themes from philosophical discourses on political authority, such as those by John Locke or arguments relating to monarchy and divine right. The quote might be from a literary source exploring these philosophical elements, but the provided texts from Locke and others do not contain the quote.
