Compound Claims and Conditional Claims

Compound claims are single claims made up of multiple claims. A compound claim, regardless of how many claims it consists of, is viewed as a single claim. For instance, consider a child breaking a lamp by playing ball in the house. Both of his parents are angry at him, but are undecided on who would punish him. So, either the father will punish him, or the mother will. As you can see, regardless of which premise happens (punishment from father or punishment from mother), the child will be punished for his behavior.

As stated by Epstein, "a claim is conditional if it can be rewritten as an 'if...then..." claim that must have the same truth value. In other words, something will only happen if a previous action occurs before. For example, Lisa will only go on a date with Jim if he pays for everything. This is considered conditional because if Jim were not to pay for everything, then Lisa would not go on a date with him.
