Explanation of Logical Propositions
The following notes on logical propositions come from a little book by Abne Eisenberg and Joseph Ilardo called Argument: An Alternative to Violence, first published in 1972 by Prentice-Hall.
Definition of a proposition: “a proposition is a statement growing out of and providing focus for a controversy; properly worded, a proposition calls for some change in belief, action, or both, thereby placing the burden of proof on its supporters and giving the presumption to its opponents” (p. 26).
Definition of issues: the “inherent” and “crucial” questions that must be answered in presenting your argument (p. 31).
Definition of stock issues: “generalized formulations, abstractions that must be applied in every specific instance” (p. 33).
Propositions come in three flavors: fact, value, and policy. A proposition of fact asks the audience to change belief about something that can be objectively verified. A proposition of value asks the audience to accept the belief that one thing is better than another. A proposition of policy asks the audience to take some action.
In supporting your argument for a proposition of policy, you must address four stock issues:
Is there a need for the proposed change?
Will the proposed change bring about a substantial improvement in the present situation?
Will the proposed change bring about these improvements without creating new and more serious problems?
Is the proposed change workable and practical?
(P. 33)
