Philosophical fiction in the context of "I Heart Huckabees"

Slipstream is a literary genre or category of speculative fiction that blends together science fiction, fantasy, and literary fiction, or otherwise does not remain within conventional boundaries of genre and narrative. It directly extends from the experimentation of the New Wave science fiction movement while also borrowing from fantasy, psychological fiction, philosophical fiction and other genres or styles of literature.

Historical examples of the genre were partially codified in Feeling Very Strange: The Slipstream Anthology; contemporary examples include Peaces by Helen Oyeyemi, The Dangers of Smoking in Bed by Mariana Enríquez, and The Butterfly Lampshade by Aimee Bender.

Thus Spoke Zarathustra: A Book for All and None (German: Also sprach Zarathustra: Ein Buch für Alle und Keinen), also translated as Thus Spake Zarathustra, is a work of philosophical fiction written by German philosopher Friedrich Nietzsche and published in four volumes between 1883 and 1885. The protagonist is nominally the historical Zarathustra, more commonly called Zoroaster in the West.

Much of the book consists of discourses by Zarathustra on a wide variety of subjects, most of which end with the refrain "thus spoke Zarathustra". The character of Zarathustra first appeared in Nietzsche's earlier book The Gay Science (at §342, which closely resembles §1 of "Zarathustra's Prologue" in Thus Spoke Zarathustra).

The Brothers Karamazov (Russian: Братья Карамазовы, romanized: Brat'ya Karamazovy, IPA: [ˈbratʲjə kərɐˈmazəvɨ]), also translated as The Karamazov Brothers, is the eighth and final novel by Russian author Fyodor Dostoevsky. Dostoevsky spent nearly two years writing The Brothers Karamazov, which was published as a serial in The Russian Messenger from January 1879 to November 1880. Dostoevsky died less than four months after its publication. It has been acclaimed as one of the supreme achievements in world literature.

Set in 19th-century Russia, The Brothers Karamazov is a passionate philosophical novel that discusses questions of God, free will, and morality. It has also been described as a theological drama dealing with problems of faith, doubt, and reason in the context of a modernizing Russia, with a plot that revolves around the subject of patricide. Dostoevsky composed much of the novel in Staraya Russa, which inspired the main setting.

The Picture of Dorian Gray is an 1890 philosophical fiction and Gothic horror novel by Irish writer Oscar Wilde. A shorter novella-length version was published in the July 1890 issue of the American periodical Lippincott's Monthly Magazine, while the novel-length version was published in April 1891. Wilde's only novel, it is widely regarded as a classic of both Gothic and English literature, having been adapted many times for films, stage, plays, and other forms of art performances, in addition to inspiring the Dorian Awards since 2009.

The work was originally commissioned by J. M. Stoddart, the managing editor of Lippincott's Monthly Magazine, as a novella in 1889, but after facing public backlash for its perceived immorality, Wilde revised the story. He added a new preface which outlined his aesthetic philosophy and also expanded the initial narrative with six additional chapters. It was this expanded version which eventually became the novel. Critics have also noted that an earlier story written by Wilde, titled The Portrait of Mr. W. H. and published in 1889, has several of the themes and styles seen in this novel. The story itself originated from a conversation Wilde had with his friend, artist Basil Ward, who was an early version of the character Basil Hallward.
