Document Summary
Some statements tell us something not about the categories themselves but about the relationship between them (hypothetical). And some statements tell us about a list of possibilities (disjunctive). These two forms of proposition are different from categorical statements in that the components are expressed but not asserted. The disjunction represents the logical term or". The terms on either side of the disjunction are called disjuncts. Unlike with categoricals, it doesn"t matter which side of the disjunction symbol the disjuncts appear on, i. e. , p or q" is the same as q or p". The exclusive disjunction is where one or the other disjunct must be true but not both. The inclusive disjunction is where one or other disjunct must be true and both can also be true. E. g. , would you like to have some coffee or cake? , or over reading week i will go to montreal or i will stay in toronto.
