This video discusses Proper Names by John Searle. My reason for posting this is to ask the question should SF or science fiction be considered a proper name?

Searle's Theory

1. Names can be a single word, or a cluster of words, that define the name

2. When descriptive names no longer describe the original thing they're still valid

3. Names don't have to be statements, or necessarily true; they're contingent facts

4. Names have a unique and plausible use within language

5. Names can describe non-existent objects or persons

6. Objects or persons can have more than one name and be the same object or person

TL;DW:  Or in this case, does the name science fiction make science fiction, science fiction?
