"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.

== The Parable ==

The text of the parable below is excerpted from Pound's ABC of Reading.

== Context ==

=== ABC of Reading ===
Pound opens ABC of Reading with the following pronouncement:

The proper METHOD for studying poetry and good letters is the method of contemporary biologists, that is careful first-hand examination of the matter, and continual COMPARISON of one 'slide' or specimen with another. No man is equipped for modern thinking until he has understood the anecdote of Agassiz and the sunfish.

In the parable, a graduate student is sent to noted biologist Louis Agassiz to complete his education, and Agassiz asks the student three times to describe a sunfish specimen. The student replies with, in turn, the common name of the fish, a brief summary of the species, and a four-page essay on the species. Agassiz finally tells the student to "look at the fish" and "[a]t the end of three weeks the fish was in an advanced state of decomposition, but the student knew something about it." The text of the parable itself spans 131 words over sixteen lines and is often reproduced in full when cited.
Pound contrasts this empiricism against knowledge gained through increasingly abstract definitions. As an example, Pound relates what might happen if a European is asked to define "red". After the initial response that red is a color, Pound imagines asking for a definition of color and having it described in terms of vibration, with vibration then defined in terms of energy, and that successive abstractions eventually reach a level where language has lost its power. Returning to empiricism, Pound reminds the reader that the progress of science increased rapidly once "Bacon had suggested the direct examination of phenomena, and after Galileo and others had stopped discussing things so much, and had begun really to look at them". Pound provides several other examples of the same contrasting ideas throughout the first chapter, ranging over topics as diverse as chemistry, Chinese writing, and Stravinsky. At the end of the chapter he summarizes his argument by claiming abstraction does not expand knowledge.

=== Literary essays ===
Pound subsequently refers to the parable in two essays: "The Teacher's Mission" and "Mr Housman at Little Bethel". Both were republished in The Literary Essays of Ezra Pound and reference Agassiz without including details of the parable. "The Teacher's Mission" in particular provides a straightforward explanation of how Pound wished the parable to be interpreted.

==== "Mr Housman at Little Bethel" ====
In January 1934, Pound published a critique of A. E. Housman's The Name and Nature of Poetry in the Criterion. As part of the critique, Pound offers an emendation to Housman's claim that "the intelligence" of the eighteenth century involved "some repressing and silencing of poetry". Pound replies that the root cause was the tendency towards abstract statements, which came about in part because eighteenth century authors "hadn't heard about Professor Agassiz's fish."

==== "The Teacher's Mission" ====
Also in 1934, Pound published an essay critiquing existing methods for teaching literature in general and university-level instruction methods in particular.  He identifies the root of the problem as abstraction and uses the word "liberty" as an example of a term where a specific, concrete meaning has been lost. Pound finds this situation "inexcusable AFTER the era of 'Agassiz and the fish'" and demands an approach to general education that "parallels ... biological study based on EXAMINATION and COMPARISON of particular specimens."

== Sources ==
Louis Agassiz was a Swiss-born scientist at Harvard University who, by 1896, had established a reputation for "lock[ing] a student up in a room full of turtle-shells, or lobster-shells, or oyster-shells, without a book or a word to help him, and not let[ting] him out till he had discovered all the truths which the objects contained." Several students of Agassiz who went on to prominence recorded this rite of passage, including Henry Blake, David Starr Jordan, Addison Emery Verrill, and Burt Green Wilder. American literary critic Robert Scholes traces the parable's source to two narratives in particular: those of former students Nathaniel Southgate Shaler and Samuel Hubbard Scudder. Their anecdotes were reprinted in Lane Cooper's Louis Agassiz as a Teacher: Illustrative Extracts on his Method of Instruction. Their separate accounts differ markedly from Pound's: both students provide oral reports with a wealth of detail after being initially forbidden from consulting outside sources.

=== Shaler's Autobiography ===

Nathaniel Shaler left his humanist studies and joined Agassiz's lab at Harvard University, having already read Agassiz's introductory essay on classification. His autobiography details his initial interactions with Agassiz. With regard to his first assignment, Shaler recorded that Agassiz brought him a small fish to study with the stipulation that Shaler not discuss it with anyone or read anything on the topic until Agassiz had given him permission. When Shaler asked Agassiz for more explicit instructions, Agassiz replied that he could not be more explicit than saying "[f]ind out what you can without damaging the specimen". After the first hours, Shaler thought he had "compassed that fish," but despite Agassiz always being "within call" he was not asked to present his conclusions. During the course of the following week, Shaler recorded the details of "how the scales went in series, their shape, the form and placement of the teeth, etc."
