# Day 15 of High School in Five Months, conversions, and Adulting Ed.

If we continue to expand the term “adulting” to include equivalencies and understanding how to determine those equivalencies, be they mathematical or rhetorical, we see Adulting Education as an essential part of any democratic educational movement:

Action Items:

1.) How would you explain or define, for someone who has never heard the word, a tautology?

2.) Share your  ideas with us, and

3.) Write a book, story, blog post or tweet that uses one of the ideas, and then, please tell us about it! If you write a book, once it is published please consider donating a copy to your local public library.

1. Tautology means repeating the same statement but in different words, be it one word or a phrase.
Why is this particular word significant (just being a curious cat)?

1. Shavuah Tov, Dear Dolly!
🙂
I’m so glad you asked about this word! 😉
I was interested in the effects of converting one symbol to another, and the logic behind recognizing what is, in effect, an example of circular logic. I wanted to draw a connection between the mathematical tautology, and that of speech, in words used, for example, in a persuasive discussion. I am hoping that it will become obvious that there is a connection between logical or critical thinking in mathematics, and the ability to recognize the equivalence of two statements in an argument, as well. I am wondering if the study of mathematics, even as basic as these mathematics in today’s lesson are, transfer directly to critical thinking in decision-making around other topics, like what to believe when reading assertions on the web, in a video, etc.
The concept of a tautology has come up so often, over the past 4 years, that I was beginning to wish that every US citizen had some training in debate, argumentation, and logic, so as to understand the logical fallacies that have been coming up so much often.

1. Thank you for an explicit explanation, dear Shira. I believe that proficiency in mathmatics does transfer to critical thinking ; unfortunately, most Americans (around 85%, according to some studies), are lacking math skills, thus lacking logic amd critical thinking. I encouter circular thinking quite often in students’ papers and presentations. I confess it sets my teeth on edge.
Big air hugs,

1. You are most welcome, and thank you, Dolly! That thinking not only set my teeth on edge, but had me grinding my teeth when my students did not want to accept their lack of logic! Made me regret having accepted the assignment to teach economic history!
But one hopes that sooner or later, STEM students will at least see the logic, as they go through their required maths courses. It’s the rest of us I worry for, even more, since most, as you point out, have not even the basic maths skills to recognize logic.

In later reviews of Babyon 5, we shall see that there is apparently a feline equivalent on every planet in the known universe! 🙂

2. A tautology is an inherently true statement that does not provide evidence for its conclusion, because its conclusion is a restatement of its claims. I’m not sure if that is exactly a good definition, but it’s something like that. Basically, something with circular logic.

I didn’t realize until googling it just now that it is also used independent of the logic field to refer to repetitive language, but I can see how the two are connected.

1. Exactly.
That is why, in my opinion, a tautology is essentially circular reasoning, and very much part of learning about logic. When discussing any topic, many people fall back on such logical fallacies, apparently without understanding that they are merely restating their initial assumptions as conclusions.
How do we help teach people to see this error?
