Identify the author who stated the following lines-There is, first, the literature of knowledge, and, secondly, the Ilterature of power. The function of the first is to teach; the function of the second is...to move: the first is a rudder; the second an oar or a sall."

The correct option is Thomas de Quincey (written as Thomas de Quincy in the options).

This famous distinction between the "literature of knowledge" and the "literature of power" was formulated by the English essayist, literary critic, and writer Thomas de Quincey.
He first introduced this concept in his essay "Letters to a Young Man whose Education has been Neglected" (1823) and later expanded upon it in his critical essay on "Alexander Pope" (1848).

De Quincey explained the difference between the two types of literature as follows:
1. Literature of Knowledge: The primary function of this literature is to teach, instruct, and communicate facts or information. It appeals to the discursive understanding or intellect. An example would be a scientific treatise or an encyclopedia. As de Quincey wrote, its symbol or function is like a "rudder" because it directs or guides.
2. Literature of Power: The primary function of this literature is to move, inspire, and appeal to human emotions, feelings, and the imagination. It communicates power and raises the reader's state of mind. Examples include poetry, drama, and creative novels. Its symbol is an "oar" or a "sail" because it provides the visual and emotional drive that propels us forward.

Therefore, the authorship of this celebrated quote belongs to Thomas de Quincey.
