Module 11 Notes
This module is devoted to the logical implications of categorical syllogisms. As we previously
learned, a syllogism is an argument with exactly two premises (disjunctive syllogisms and
hypothetical syllogisms were briefly discussed in Modu

Module 2 Notes
We learned that that there are two contrary views about how to interpret the
meaning of universal categorical propositions. Thus far, we have been examining
the view of George Boole, which holds that a type A or a type E proposition is
Module 3 Notes
The formal operations of conversion, obversion and contraposition can be applied to
categorical propositions to yield new, logically equivalent propositions. Two
propositions are said to be logically equivalent if their truth value is neces
Module 4 Notes
Very similar to the contrary relation, type I and O propositions have a subcontrary relationship.
Within Aristotle's system, when we encounter corresponding I and O categorical propositions, at
least one of these statements mus
Module 5 Notes
The operations of Aristotle's traditional square of opposition rely on existential import-that is that the proposition is about something that actually exists. Thus whenever an
inference's conclusion relies on a contrar
Module 6 Notes
As we have seen with the use of the square of opposition, Aristotle's view of logic
interprets the meaning of universal categorical propositions very differently from Boole.
On an Aristotelian account, a universal proposition is making an e
Module 7 Notes
With a standard form proposition, there are only two permissible verbs: "are" and "are not."
Statements that use other types of verbs can be translated into standard form as follows:
Some turkeys will not live pa
Module 8 Notes
Quantifiers are rarely expressed when we use ordinary language. Thus to put these statements into
standard form, we need to decide whether a universal or particular claim is implied.
Elephants are big.Hotel rooms are expensive.
Module 9 Notes
Conditional statements (if.then) that refer to things can often be reexpressed as standard form
propositions. These types of statements are always interpreted as universal propositions.
If it is Monday, the
Module 10 Notes
Statements that use the words "only," "none but," "none except," and the clause
"no.except" are called exclusive propositions. These types of statements are best
translated by first restructuring them as a conditiona
