Summary
There are two types of horror stories: stories about mad scientists and stories about monstrous beasts.
In some stories about monstrous beasts, the beast symbolizes the psychological disturbance of the protagonist.
In some stories about mad scientists, the author expresses the feeling that science isn’t enough to guide humanity.
Both kinds of stories describe violations of the laws of nature and are intended to produce dread in the reader.

Some stories that describe violations in the laws of nature are also intended to produce dread in the reader.

Some stories that symbolize the protagonist’s psychological disturbances describe violations of the laws of nature.

If the statements above are █████ █████ ███ ██ ███ █████████ █████ ████ ████ ██ ██ █████
a
All descriptions of █████████ ██████ ████████ ██████████ ██ ███ ████ ██ ███████
This could be false. We know that all horror stories that are about monstrous beasts describe violations of the laws of nature; maybe stories with monstrous beasts of other genres don’t describe violations of nature.
b
Any story that █████████ █ █████████ ██ █ ███ ██ ██████ ██ ████████ ██ ██████ █████ ██ ███ ███████
This could be false. We only know about horror stories that describe a violation of nature, not all stories that do so.
c
Horror stories of ███ ████ ███████ ████████ ██████████ ███ ███ ███████████████ ██████████
This could be false. We don’t know that horror stories “of any kind” usually describe characters’ psychological disturbance; we just know that horror stories about monstrous beasts sometimes describe psychological disturbance.
d
Most stories about ███ ██████████ ███████ ███ ████████ ██████████████ ██████
This could be false. We don’t have any indication that authors have antiscientific views; some authors may just believe that science alone isn’t enough to guide human endeavor.
e
Some stories that ██████ █████████ ████████ ██████████ ██ ███ ████ ██ ███████
This must be true. Whether a horror story is about a scientist or a beast, it describes a violation in the laws of nature. Some horror stories about beasts use symbolism, so there is overlap between stories that use symbolism and those about violations of natural laws.
