Hey everyone! I’m new and wanted to gather up some syllogisms from all of Aristotle’s works and let us all try to tear them apart 
I’ll try to get the ball rolling.
From “Generation of Animals” at 716a19-27:
1-Male and female animals have different functions
2-Different functions require different instruments
3-The instruments in animals are body parts
Therefore, male and female animals have different body parts.
This is how I’ve extracted the argument. Have at it everyone.
