There are two kinds of horror stories: those that describe a mad scientist's experiments and those that describe a monstrous beast. In some horror stories about monstrous beasts, the monster symbolizes a psychological disturbance in the protagonist. Horror stories about mad scientists, on the other hand, typically express the author's feeling that scientific knowledge alone is not enough to guide human endeavor. However, despite these differences, both kinds of horror stories share two features: they describe violations of the laws of nature and they are intended to produce dread in the reader.
