The Conjectural Agnostic is a poetic narrative concerning someone's character, originating in The Fallacious Nightwing of Ridges. The rules of the form are applied by poets to produce individual poems which can be recited. The poem is a single couplet. A form of parallelism is common throughout the poem, in that certain lines use the same placement of allusions. The second line of the couplet presents a different view of the subject of the first line. The first line is intended to make an assertion. It has four feet with a syllable weight pattern of short-long (quantitative iambic tetrameter). The second line is intended to undercut the previous assertion. It must make use of alliteration. It has six feet with a syllable weight pattern of long-short (quantitative trochaic hexameter).
