A post-graduate student equipped with honors and diplomas went to Agassiz to receive the final and finishing touches. The great man offered him a small fish and told him to describe it.
Post-Graduate Student: "That's only a sunfish."
Agassiz: "I know that. Write a description of it."
After a few minutes the student returned with the description of the Ichthus Heliodiplodokus, or whatever term is used to conceal the common sunfish from vulgar knowledge, family of Heliichtherinkus, etc., as found in textbooks of the subject.
Agassiz again told the student to describe the fish.
The student produced a four-page essay. Agassiz then told him to look at the fish. At the end of three weeks the fish was in an advanced state of decomposition, but the student knew something about it.
Pound contrasts this empiricism against knowledge gained through increasingly abstract definitions.
Parable of the Sunfish
"The Parable of the Sunfish" is an anecdote with which Ezra Pound opens ABC of Reading, a 1934 work of literary criticism. Pound uses this anecdote to emphasize an empirical approach for learning about art, in contrast to relying on commentary rooted in abstraction. While the parable is based on students' recollections of Louis Agassiz's teaching style, Pound's retelling diverges from these sources in several respects. The parable has been used to illustrate the benefits of scientific thinking, but more recent literary criticism has split on whether the parable accurately reflects the scientific process and calls into question Pound's empirical approach to literature.

ABC of Reading
ABC of Reading[1] is a book by the 20th-century Imagist poet Ezra Pound published in 1934. In it, Pound sets out an approach by which one may come to appreciate and understand literature (focusing primarily on poetry).
Despite its title the text can be considered as a guide to writing poetry. The work begins with the "Parable of the sunfish", features a collection of English poetry that Pound called Exhibits and several notable quotations.
