  2. Definition • The set of conditions necessary for any given proposition p to be true is known as the truth conditions of p. • Truth conditions are often also called entailments. • If a proposition p is true, then all truth conditions must be satisfied, i.e. all entailments of p must be true. Note: If an entailment of p is false, then p is false.

  3. Example Consider the proposition expressed by the sentence The child pinched an elephant. • False if nothing was done to any elephant. • False if the act upon any particular elephant by the child was not pinching. Some truth conditions: • Something was done to an elephant. • The elephant was pinched.

  4. Sentences & Propositions • Truth conditions apply to propositions, not sentences. • Propositions are often expressed in sentences, but needn’t be. The man in yellow is blowing bubbles.

  5. Sentences & Propositions A sentence may contain numerous propositions, while itself being a proposition. The child tickled the elephant and the elephant ran away. Proposition 1: The child tickled the elephant. Proposition 2: The elephant ran away. Proposition 3: Conjunction of Proposition 1 & Proposition 2.
