Abstract: Using “The Fantasy Trilogy”, Diaboliad, The Fatal Eggs, and The Heart of a Dog, the three novellas written by the great Russian novelist Mikhail Bulgakov, as the primary sources, this article tries to probe into the scientific ethical consciousness reflected in his literary works. The short novels by Bulgakov are characteristic not only for his superb art of satire, but also for his serious ethical warning. What is uniquely inspiring in Bulgakov’s works is a great stress on the oneness between the scientific spirit and the idea of morality. Scientific activities must stand up to the close supervision and scrutiny of the morality; scientific and technical experiments, as well as the relevant scientific studies, must follow the guidelines of scientific ethics. With the rapid progress of society and the development of sciences, scientific selection is inevitable. However, without the constraint of the scientific ethics, “ethical violations” would be hard to avoid. Through various specific examples, such as biological tests and the transplantation of organs, Bulgakov offers us a stern warning that the humankind would inevitably suffer a great deal of disasters if the research in sciences and the application of technologies were conducted without the constraint of scientific ethics. Obviously, such a warning has a profound significance in his works.

Key words: Mikhail Bulgakov, "The Fantasy Trilogy", scientific ethics, scientific selection
