Kairosis is the literary affect of fulfillment in time. This affect is normally associated with the epic/novel genre of literature. This affect can be understood by the ratio "as catharsis is to the dramatic, so kenosis is to the lyric, so kairosis is to the epic/novel."

Kairosis is the feeling of integration experienced by the reader of the novel or epic form. Kairosis is experienced by the reader as the central protagonist's character and characterisation faces crisis and resolves itself into an explored and integrated personality. This typically occurs by challenging unique and interesting characters with typical and stereotyped actions that are generally applicable to all people.

In the novel Emma, kairosis is developed when an individualistic young woman attempts to play match-maker to the world. As her personality is challenged by the stereotypical activity of courtship and matchmaking in a young woman's life, she experiences a crisis in her character as contradictions within her personality become increasingly antagonistic. When Emma integrates these conflicts, by performing the stereotyped action of completing a successful match, the reader experiences kairosis as Emma's character reaches a moment of synthesis that embodies the previous dialectical contradictions.

Emma's problem was not to gain a social status of marriage: we are always aware that she will be married by the end of the novel and there is no catharsis experienced as an unexpected climactic action. Rather, we do not know if Emma is worth marrying. This kind of moral-psychological question is at the heart of Austin's work, and the modern novel. Kairosis is experienced by the reader of the modern novel when the character reaches a moment of psychological integration in time.
