Deductive Arguments and Logical Form

One of the essential features of a successful deductive argument is that the logical form of the argument is valid. This text introduces the concept of logical form, and uses Venn diagrams and the logical symbol for sufficient condition to illustrate how the logical form of a deductive argument determines whether the argument is valid or invalid.
