Todorov's greatest contribution to literary theory was his defining of the fantastic, the fantastic uncanny, and the fantastic marvelous. Todorov defines the fantastic as being any event that happens in our world that seems to be supernatural. Upon the occurrence of the event, we must decide if the event was an illusion or whether it is real and has actually taken place. Todorov uses Alvaro from Cazotte's Le Diable Amoureux as an example of a fantastic event. Alvaro must decide whether the woman he is in love with is truly a woman or if she is the devil.
Upon choosing whether the event was real or imaginary, Todorov says that we enter into the genres of uncanny and marvelous. In the fantastic uncanny, the event that occurs is actually an illusion of some sort. The "laws of reality" remain intact and also provide a rational explanation for the fantastic event. Todorov gives examples of dreams, drugs, illusions of the senses, madness, etc. as things that could explain a fantastic/supernatural event. In the fantastic marvelous, the supernatural event that occurs has actually taken place and therefore the "laws of reality" have to be changed to explain the event. Only if the implied reader cannot opt for one or the other possibility, the text is purely fantastic.
Aside from his work in literary theory, Todorov also dabbled in philosophy a bit. He wrote Frail Happiness about the writings of Jean-Jacques Rousseau. He focuses on Rousseau's ideas of attaining human happiness and how we can live in 'modern' times.
