  12. Necessary and Sufficient Conditions • These terms refer to relations between facts.

  13. Necessary Conditions • A condition q is necessary for p if it is impossible for something to be p without being q.

  15. Necessary Conditions Example: Being an animal is a necessary condition for being a mammal. Being married is a necessary condition for getting a divorce.

  16. A Diagram of Necessary Conditions Everything inside the large circle is an animal; nothing outside the large circle is an animal. Animals Mammals

  17. A Diagram of Necessary Conditions Everything inside the large circle is an animal; nothing outside the large circle is an animal. Everything inside the small orange circle is a mammal; nothing outside the small circle is an animal. Animals Mammals

  18. A Diagram of Necessary Conditions Everything inside the large circle is an animal; nothing outside the large circle is an animal. Everything inside the small orange circle is a mammal; nothing outside the small circle is an animal. Since the small circle is entirely enclosed within the large one, you can say that it has to be animal if it is a mammal. Animals Mammals

  19. A Diagram of Necessary Conditions Everything inside the large circle is an animal; nothing outside the large circle is an animal. Everything inside the small orange circle is a mammal; nothing outside the small circle is an animal.

  21. Example of sufficient condition • Being a mammalis a sufficient condition for being an animal, because it is impossible for something to be a mammal and not be an animal.

  22. Example of sufficient condition • . Put slightly different, if you know p is a mammal, that’s enough to know that p is an animal. Animals Mammals

  23. Example of sufficient condition • . Put slightly different, if you know p is a mammal, that’s enough to know that p is an animal. Animals Mammals
