Is this logic proof "good enough"?
Hello. I am trying to get a logic proof done for an imperative statement I am trying to make but am not a logician and thus asked chatGPT to do the proof for me (I am currently studying logic, however, and only just beginning) and wanted to see if someone could tell me if the proof is "good enough" to stand as true. Please see the extended explanation section for the proof that ChatGPT gave me. [more inside]
What Is The Name Of This Book?... For Dummies
I've just started working through Raymond Smullyan's classic text of logic puzzles What is The Name Of This Book? with offspring #2 and they, not trusting my explanations of such things, have asked if there's an answer-sheet with breakdowns of the solutions for it anywhere, as the book doesn't answer the questions it poses. Can anyone point me to one?
I want to have FUN with math and logic
Over a period of years, I've wrestled myself out of a liberal arts path into a math-and-logic-y career (software engineering). I know intellectually that I am smart enough to do this job, but on bad days I still feel like I'm weak at math and logic, and all of my hobbies involve liberal arts, community and culture. Are there games/puzzles I could add into my leisure rotation that would build math, reasoning and engineering skills? Bonus if they are not in front of a screen. [more inside]
"Necessary if Sufficient" !?
Is the phrase "necessary if sufficient" a term of art in logic or philosophy? If so, what does it mean? [more inside]
Is there such a thing as "sound" ethics a la "sound logic"?
If not, how close can one get to proving something ethically "true" or not?
Part of the reason I am asking this question is because I want to see what would be necessary for creating a "calculator" which could be used to replace representational government (since itʻs absurd that we are still subjecting ourselves to the whims and opinions of "legislators" like Joe Manchin to make decisions on behalf of humanityʻs future).
Music/logic apps?
Fairly early in the smartphone era, I had a phone game that was a logic game or puzzle using simple geometry and also ?harmony?, represented by something like fluid dynamics. It was pleasant to listen to and got difficult pretty quickly. I think it started in black and white and developed colors. The name was vaguely portentous, and maybe started with R. Do you remember such a thing? [more inside]
How can I get the smart tempo function to work in Logic Pro
Does anyone other there use Logic Pro's smart tempo? I can't seem to get it to work properly. [more inside]
How did you logically convince yourself not to worry?
I would like to eliminate some existential dread from my life, where it is sensible to do so. [more inside]
What is the name of this logical fallacy
"If a system is working in my favor, then the system works. If the same system (under the same conditions as the original) is not working in my favor, then the system must be flawed.
Puzzles for the mathematician
My husband loves these types of puzzles. He is a mathematician and solves even the toughest ones pretty easily. Looking for suggestions on tough puzzle or logic toys/games that will challenge him.
More games like this
I really enjoy the text-based "logic puzzles" on Sporcle (e.g. Carmen Sandiago puzzle). There's only a handful of them on Sporcle. Googling "logic puzzle" yields different logic games, not the specific type I'm looking for. Do these have another name I could search for?
I don't blame MetaFilter but…
"I don't condone this behaviour but the way MPs behave, they must take a certain amount of blame." Is this a logical fallacy? [more inside]
Making Sense
I seem to remember, as I was growing up, that people talked of the "Theory of Gravity." Between then and now, I believe it has become the "Law of Gravity." I'm thinking about things that should be incontrovertible logic. Looking at the political turmoil, the vaccination debates and conspiracy theories, I wonder if there are people who simply do not agree with principles like 1+1=2 or A follows B. [more inside]
Favorite Source for Logic Puzzles
We have a sudden mania for logic puzzles in our house! What are your favorite sources for logic puzzles? (Online, print, whatever.) I would double extra love a site with a "logic puzzle of the day" (or even week) that I could put in my RSS reader. A range of difficulties would be great.
Looking for the logic in anatomy
I'm looking for a specific kind of anatomy resource (book, online course, etc.). There are numerous resources that will tell me the location of muscles, their origin/insertion/action/etc. I want one that emphasizes patterns, comparisons, and the reasons why things are the way they are.

Rhetorical figure / argumentative strategy: Classical term needed
Any rhetoricians here? How is the following rhetorical figure called: Person A asks a difficult and complicated question and hopes to obtain a well-founded answer. Person B answers in an even more complicated and longish manner, obfuscating the fact that he / she is not able to comply with A’s expectation. Now, "obfuscation" is not the word I’m looking for, nor is "obscuration" or "overcomplication" (what comes closest to the strategy itself). What I need should be classical technical term like "reductio ad absurdum". Shouldn’t such a terminus exist, given the tradition (and the ongoing prevalence) of this figure?
Self-refential quiz
Looking for a self-referential multiple-choice quiz that I saw in... 2003? 2001? It is similar in content to the James Propp Self-Referential Aptitude Test that is all over google search results but is categorically not that one. [more inside]
ISO: puzzle game, PC, late 80s, early 90s, logic, computation
I remember this game had many different puzzles presented with a very relaxing, sort of new-agey, graphical aesthetic. The first set of puzzles was a square grid of mostly blue cells and I don't remember what it was about but you had to conserve some resource in solving the puzzle, roughly analogous to memory management in a computer. At the time I played it, I thought it was pretty hard. More vague, likely spurious details within. [more inside]

Can p → q |- ¬p ∨ q in intuitionistic logic?
Can you prove p → q |- ¬p ∨ q without using the law of the excluded middle or its equivalent? I'm going through a logic book (introductory) and I have an intuition that proving this isn't possible constructively, but I'd like a confirmation.
Philosophy Training
I am looking into founding a training company to offer critical thinking / logical analysis / other philosophy related skills to businesses.
This is not something we really know how to do.
Have you either hired training for a company or been involved in doing it?

No True English Teacher Would Ask This Sort of Question
I've recently discovered that I'm supposed to be teaching logical fallacies and argumentation to a couple classes of second year high school returnee students. I'm looking for solid ideas or examples for use in teaching students how to recognize and avoid using fallacies. However, there've been some snags. [more inside]
Easiest Way to Create an Interactive, "Multi-Factor" Game/Exercise?
Programming-challenged foodie here, trying to create a cooking activity for a staff event: From a list, you choose ingredient A as a starting point. Then you choose other ingredients to add to A (D and W, say), and see the result: A+D+W—a dish you can make at home. How can I create something (digital, paper, or otherwise) that allows people to choose any ingredient, add any others, and see a possible resulting dish? [more inside]
Thinking Critically
What puzzles, games or new activities can I do to keep improving my critical thinking, analytical, and logical abilities? AKA "Continuing Ed" for liberal arts graduates who have a hard time with "2 + 2" (when they're intoxicated, anyway...). [more inside]
Making an old MacBook Pro work for a single purpose
I have a pretty old MacBook pro (probably 7-8 years old) that's very sluggish and glitchy. I'd like to relegate it for the single purpose of running Logic Pro. It currently runs Logic but very slowly and crashes often. Can I like wipe the whole thing somehow and make it do nothing but run Logic well? [more inside]
Challenges, Puzzles and Courses in Maths, Logic and Computing
I'm looking for challenges, puzzles and "teach yourself" courses that involve maths and logic, probably related to computing. Ideally I'd like a curated source (mailing list or regularly updated website), but perhaps the best we can do is collect them here. Inside I will give examples of what I mean by "challenges, puzzles and courses". [more inside]
looking for Work Plan/ Work Breakdown Structure and Logic Model Template
Hi Hive Mind
I would like to create a work plan and a logic model for a project, and I am looking for resources/templates for a Work Plan/ Project Plan/ Work Breakdown Structure as well as a Logic Model.
I am looking for something that is clean, easy and simple. I would prefer a Word doc over Excel.
Would you have any templates that you have found useful in the past?
I found this example, which I attached, and have been trying to tweak. Metahives do you have anything?
Thanks!
Examples of book-length arguments?
In my last question I asked how to structure long, intricate arguments. Now I'm specifically asking for book-length examples that make the argument explicit. [more inside]
Start making sense
I’m looking for suspenseful, edge-of-your-seat movies (horror, mystery, thriller, action) that are reasonably realistic and have a conclusive, unambiguous ending. When watching movies, I’m always willing to suspend some disbelief, but only up to a point. I’m turned off by gaping holes in the plot line, implausible twists, and puzzling endings. [more inside]
How to Math
I'm a computer science major in college. I'm not a freakin' genius, but I do well-- get A's in my classes, good with abstraction (e.g. pointers), etc. However, I seem to have missed... my entire high school pre-Calculus math curriculum? I don't know. [more inside]
Physical Computational Thinking
What are some fun physical games and activities that can be used to teach computational thinking? Good topics would be algorithmic processes, graph and network theory, cryptography, boolean logic, computational problem solving, etc. These would be for beginners, but examples at any level (elementary, primary, college) are welcome.
More self-confidence for approaching games and puzzles
I've reached the proverbial straw moment where I'm realizing that, approaching any sort of numbers/critical thinking game or challenge that is meant to be fun, is instead filling me with absolute dread. I find myself becoming incredibly tense and anxious, and very often preemptively angry at myself for OF COURSE being too stupid to pick it up, which means that often I don't even try to pick it up, which then becomes an inescapable feedback loop. I need to change this, please tell me how! [more inside]
Mapping a midi keyboard by frequency?
I would like to use some software (preferably Logic Pro, but would be open to a different software if necessary) to map a midi controller using specific frequencies, as opposed to pitches or other sounds. Basically, I'd like to be able to compose music with a midi keyboard where each key gives me a sine wave (or perhaps other wave of my choosing) of some frequency(ies) I select. [more inside]
Theories of the Ontology of Logic and Reason?
I have recently become interested in the question of what sort of existence or "being" logical laws, reason, mathematical truths, rationality have. That is, what is the ontological basis of logic? Where does the a priori reside? Is it part of the universe or if it is somehow "absolute" then "where" do these truths reside? Who has theorised about this, can you give pointers of philosophers, and books that have tackled this issue? Did Russell or Frege talk about this? Plato's realm of Ideas seems one approach to the problem but what are contemporary theories?
Name That Logical Fallacy-Filter
Quick 'n dirty: is there a name (in either classical logic/reasoning OR a newly-coined term) for the belief that "if you hold a different opinion on a topic than I, it must be due to a deficiency in information/experience/intelligence on YOUR part" (in other words - "anyone sufficiently smart/experienced/informed, when presented with this issue, would inevitably draw the same conclusion as I"). E.g. "You're a [member of political party] NOW, but that's only because you haven't [something] yet!", or "Wow, you believe in [thing]... maybe you should DO SOME RESEARCH and see if you don't change your tune!"
Puzzle me this
I'm organising a competition in which groups of people have to work together to solve a series of puzzles. I'm looking for puzzles along the lines of that hoary old favourite about the Farmer trying to cross the river with a Fox, a Chicken and Bag of Grain or the one involving the Two Guards, one of whom only tells lies and the other who only tells the truth. [more inside]
Cheat like a fox.
I have always been really bad at really simple games, like the ones where there are generally sound mathematical strategies for playing the optimal game. I'd like to compile a little mental rolodex of simple games and their solutions so I can feel smugly superior to any small children who seek to challenge me. [more inside]
Learning Logic
I would like to take a college course on logic. I am not currently enrolled in any college. And, I have missed registration for the fall semester for most community colleges and adult ed centers. I bought a book on logic but I am having trouble learning from it. Would prefer to use a book in conjunction with lectures. How should I proceed?
Typically this type of course is offered in the philosophy department. My main interest is in dissecting arguments to find logical structures.
I am open to taking an online course or even listening to a set of lectures on logic, especially if a workbook is required.
thank you.
Clever, low-stress, RSI-friendly, eyecandy puzzle-adventure type games?
Need moar gamez, plz hope! (for Mac or iPad.) I love Myst-type, atmospheric, "wander around beautifully illustrated worlds and solve puzzles" type games, especially with at least a little narrative quality, and want to avoid timed segments (do this within a timed period or fail), explicit / realistic violence (I don't really want to be killing things or wandering around bloody rooms, etc.), or games where advancement hinges on say, physically jumping from one thing to another thing in just the right way, at the right speed, etc. Specifically, I don't want to have to do much or any repetitive clicking/tapping movements, because ouch.

Teaching critical thinking?

What's a good analogy for prioritizing work process tasks?
At my company customers place orders online. Orders get selected for fraud screening and need to be worked in the most efficient way possible. Some orders take priority (customer pays for rush shipping and order needs to be screened today, so the warehouse can get it out the door). Currently orders are split into separate reports based on priority and workers are assigned to one report at a time. I want to combine them all into one report and assign all workers to that report.

Did Charles Babbage ever read Leibniz on logic?
Charles Babbage was a prominent member of the Analytical Society, and was at the very least intimately familiar with Leibniz's formulation of calculus. But did he ever read Leibniz's writings on logic? Did the Ars Combinatoria, or any of his writings on the "universal characteristic" or "calculus ratiocinator" influence Babbage's thinking about computation?
Podcasts that Persuade
Please recommend specific episodes of podcasts that make a clear, logical, and sustained argument. I'm looking for podcasts in the This American Life, Radiolab, and 99% Invisible genre that attempt to persuade, rather than just inform. Thanks! [more inside]
