I was experimenting with RACE, and don't understand the results I get
below, specifically Subset 3 and Subset 6
I can understand that "something" is acting as a name for a constant but
when Something = Mary how do I express
the idea that the substitution is under the constraint of being male ?
*Axioms*: Every man is a human. Every woman is a human. Mary is a woman.
John is a man. Fido is a dog. No dog is a human. John is a male. Fido is a
male.
*Theorems*: Something is a male.
*Parameters*:
The following minimal subsets of the axioms entail the theorems:
- Subset 1
- 7: John is a male.
- Substitution: something = Fido
- Subset 2
- 7: John is a male.
- Substitution: something = John
- Subset 3
- 7: John is a male.
- Substitution: something = Mary
- Subset 4
- 8: Fido is a male.
- Substitution: something = Fido
- Subset 5
- 8: Fido is a male.
- Substitution: something = John
- Subset 6
- 8: Fido is a male.
- Substitution: something = Mary
overall time: 1.75 sec; RACE time: 0.16 sec
