Each of the following exercises gives a passage from the U.S. Constitution, followed by another statement. (a) Translate the passage from the Constitution into a statement in symbolic logic. (b) Find a valid conclusion using as premises the passage from the Constitution and the statement that follows it. (c) Illustrate the argument with an Euler diagram. No person shall be a Representative who shall not have attained to the age of twenty-five years, and been seven years a citizen of the United States, and who shall not, when elected, be an inhabitant of that State in which he shall be chosen. (Article 1, Section 2) John Boehner is a Representative.

Key Concepts

Symbolic Logic Translation

This concept involves converting statements expressed in natural language into formal symbolic notation. It requires identifying the underlying logical structure of the sentence, determining the appropriate predicates and quantifiers, and systematically converting the conditions into a form that supports precise inference and analysis.

Deductive Reasoning

Deductive reasoning is the process of drawing logically necessary conclusions from given premises. In this context, it involves starting with the established conditions expressed in formal logic and applying inference rules to determine what conclusions must follow if the premises are true.

Euler Diagrams

Euler diagrams are visual tools used to represent relationships among sets or groups, typically illustrating intersections and exclusions. They help in understanding and explaining logical arguments by visualizing how different conditions or categories overlap and interact, making it easier to assess the validity of the argument.

Transcript

00:01 So for this statement, we're analyzing a passage of the u .s.

00:06 Constitution, which the basic premise states to be a representative.

00:10 You shall have served, you shall be of the age of 25, she'll have been seven years a citizen, and you should be a representative of the state in which you're elected.

00:21 So i've gone ahead and defined a couple variables.

00:23 R being r of x being a representative, a of x being of 25 years of age, s of x being 7 .6 being 7 .000.

00:30 Years a us citizen and i of x being inhabited the state on which you serve.

00:36 So the way that we shall approach this problem is that we know that all us representatives meet those three criteria.

00:43 So when we're using the word all, we go to the universal quantifier for all x and then we're creating a subset of representatives.

00:53 So when we're creating the subset of representatives, we're going to use this r of x.

00:56 So for all x, if you're a representative, so that means that's a conditional statement.

01:05 If you're a representative, then you fulfill all these criteria, and that can just be indicated by a conjoined and statement.

01:13 So we have a of x and s of x and i of x.

01:21 And this is the way to state that in logic.

01:30 So the next thing that we have is we're going to analyze.

01:33 The premises that starting with a representative, so the premises that we have here, and john boner is a representative.

01:44 So what can we say about him? well, he meets, if he isn't representative, then we know that these three things have to be true.

01:54 So john bonner is at least 25 years of age.

01:57 He has been a u .s.

01:59 He has been a u .s.

02:00 Citizen for at least seven years...
