I found this argument in the I Tyrant AD&D supplement and decided to try it out in symbolic form just because I could. Beholders are both seekers of knowledge and power and are also paranoids.
It is necessary to acquire knowledge at any cost. I have knowledge others do not; some of these ignorant creatures are of the ideal breed; therefore, others of the ideal breed are out to get me.
Paraphrasing:
- For everyone and for all knowledge these don't have, then it is necessary to acquire it
- For everyone and for all knowledge If I have it and it has to be acquired by them, then they are out to get me
- There's knowledge I have and there are members of the ideal breed who don't have it
Therefore, there's a member of the ideal breed who's out to get me
Symbolizing:
Me=m

∀x(∀y(Ky˄Hmy˄Axy)→Gxm)

Premise (enthymeme)

∃y(Ky˄Hmy˄∃x(Bx˄~Hxy))
|
Premise

∴

∃x(Bx˄Gxm)

Conclusion

Alternate:
- For everyone and for all knowledge they don't have, then it is necessary to acquire it from anyone
- For everyone and for all knowledge, If it has to be acquired from anyone then they are out to get those
- There's knowledge I have and there are members of the ideal breed who don't
Therefore, there's a member of the ideal breed who's out to get me
