This document discusses logical arguments and fallacies. It provides examples of different types of arguments including identifying the conclusion, reasons/evidence, and assumptions. It then explains common logical fallacies such as appeals to authority, slippery slopes, strawman arguments, and false causes. The document cautions that correlation does not necessarily imply causation and uses examples to illustrate this point.

Fallacies
There are many different ways our reasoning can be flawed, but some of these mistakes are so common that they have names. This chapter explores fallacies, inhabitants of the often ridiculous but not always obvious world of flawed reasoning.
A fallacy is a type of flawed reasoning, while a fallacious argument is an argument that commits a fallacy. There are two great reasons to study fallacies: to prevent yourself from being fooled by them, and to prevent yourself from committing them unintentionally.
Ground Rules
· Fallacies can be found in both deductive and inductive arguments.
· Fallacies can seem very plausible and, when undetected, are often persuasive.
· The presence of a fallacy doesn't necessarily mean the conclusion is false. It just means that the logic is flawed and so the argument isn't compelling.
Tips for Spotting Fallacies
· Become familiar with the common ones.
· Evaluate assumptions in an argument.
· Find the conclusion, and then ask yourself if the premises are relevant to it.
· Look for things in the argument that distract your attention from the main point.
Common Fallacies
For the rest of the chapter we are going to explore 12 of the most common fallacies.
1. Red herring: fallacy in which the arguer raises an irrelevant side issue to distract the opponent or audience from what is really at stake.
I don't know why you're arguing that working a full day on Saturday drains you and makes you less productive in the work week. You should consider yourself lucky... before there were unions, factory laborers would have to work 14 hours a day for six days a week!
Bringing up the conditions of factory workers in pre-union days is mostly irrelevant to the opponent's main point that a full day of work on Saturday reduces productivity for the following week.
2. Appeal to popularity: fallacy in which the arguer attempts to bolster his or her argument by mentioning that "everybody" (or a large group of people) shares the same belief, preference, or habit.
Diane, getting an iPhone will make your life better. I mean, look around—practically everyone in America has an iPhone by this point!
The fact that millions of people own iPhones is not a logically sound reason to believe that buying one will make Diane's life better.
3. Post hoc ergo propter hoc: fallacy in which the arguer assumes that because there is a correlation between two events (i.e., one preceded the other), then the first must have caused the second. The phrase is Latin for "after this, therefore because of this."
In the years after nutrition facts were added to food packaging, obesity rates in the United States rose higher than ever before. Therefore, listing nutrition facts causes people to get fatter.
Just because the rise in obesity rates happened to coincide with the new practice of listing nutrition facts, no logical reason is offered as to why one might have caused the other.
4. ...
The slides aim to train members of Ateneo Debate Union to detect fallacies in argumentation. It is the hope that this would enhance their case construction skills. The principles used borrows heavily from logic.

Evaluating Moral Arguments
What Is Moral Reasoning?
Moral reasoningis ordinary critical reasoning applied to ethics.
Critical reasoning(also called critical thinking) is the careful, systematic evaluation of statementsand arguments.
Statements
A statement(or claim) is the assertion that something is either true or false. The following are examples of statements:“Murder is wrong.”“1 + 1 = 2”“Shakespeare wrote The Tempest.”
Statements and Arguments –1
When at least one statement attempts to provide reasons for believing another statement, we have an argument—a group of statements, one of which is supposed to be supported by the rest.
Statements and Arguments –2
The supporting statements are called premises.
The statement that is being supported by the others is the conclusion.
Identifying ArgumentsAn argumentis intended to prove something.All arguments share a pattern: at least one premise is required to support a conclusion.A cluster of unsupported claims is not an argument.The most reliable way to identify arguments is to look for the conclusion first.Look for indicator words:terms that often appear in arguments and signal that a premise or conclusion may be nearby.
Some words indicating a conclusion:
Therefore, consequently, hence, it follows that, thus, so, it must be thatSome words indicating a premise:
Because, since, for, given that, due to the fact that, for the reason that, the reason being, assuming that, as indicated by
Two Forms of Argument
A deductive argumentis supposed to give logically conclusivesupport to its conclusion.
An inductive argumentis supposed to offer probablesupport to its conclusion.
Common Deductive Argument FormsValid forms:Denying the antecedentAffirming the consequent Invalid forms:Affirming the antecedent(modus ponens)Denying the consequent(modus tollens)The hypothetical syllogism
Deductive Arguments
A deductive argument isvalidif the premises support the conclusion. That is, the conclusion follows necessarily from the premises. If the premises are true, then the conclusion must be true.
A deductive argument is invalidif the premises do not support the conclusion. That is, the conclusion does not follow necessarily from the premises. If the premises are true, then the conclusion may or may not be true.
A deductive argument is sound if it is valid and all its premises are true.
A deductive argument is unsound if it is invalid and/or any of its premises are false.
Inductive Arguments
An inductive argument is strongif it gives probable support to its conclusion. That is, if its premises are true, its conclusion is also likely to be true.
An inductive argument is weak if it does not give probable support to its conclusion. That is, if its premises are true, its conclusion is not more probable than not to be true.
An inductive argument is cogentif it is strong and all of its premises are true.
An inductive argument is not cogent if it is weakand/or any of.

Faulty Arguments,Logical Fallacies and Poor Re.docxmydrynan
Faulty Arguments,
Logical Fallacies
and
Poor Reasoning
Faulty ArgumentsThis PowerPoint contains some of the common errors people make in reasoning. If you listen, you will hear many of these fallacies in everyday conversation.The “natural” cure and herbal medicine literature is rife with glaring examples of poor argumentation.Study these generic examples and you will be able to spot them in the assigned articles with ease.
Poor Logic
Emotional AppealThis is an attempt to sway the listener by getting him emotionally involved. Emotions shut down reason!Sick or scared people are especially vulnerable.
Ad Hominem/ Personal AttackArguments of this kind focus on the character of the person advancing it; they seek to discredit positions by discrediting those who hold them. They attack the arguers rather than the arguments.Politicians are often subjected to ad hominem attacks
Bandwagon/ Ad PopulumThe difference between the two is that the bandwagon fallacy places an emphasis on current fads and trends, whereas the ad populum suggests that an idea must be true simply because it is widely held.
Appeal to AuthorityFor example, an appeal to authority argument seeks to persuade by citing what someone else, a perceived authority, thinks on the subject, as if that resolves the question. The degree of support that such an appeal lends to a claim varies depending on the particular authority in question, the relevance of their expertise to the claim, and other factors, but in all cases is limited.
Appeal to AuthorityAn appeal to authority argument seeks to persuade by citing what someone else, a perceived authority, thinks on the subject, as if that resolves the question. Celebrity endorsements sell products.Even worse, celebrity endorsements of political figures win votes. Yikes!
Faulty StatisticsMisunderstanding or misusing statistics to shore up a weak argument.Example: “We must fund our schools better! Half our children are below average on their math tests!”People pull bogus statistics out of thin air to sound impressive.
Research by ExegesisResearch by exegesis is using a book as an infallible reference source.Usually it refers to the supposedly infallible Bible, but not always.People cite Bible verses to convince people that being gay is wrong.
Either/Or & Slippery SlopeSlippery slope arguments falsely assume that one thing must lead to another. They begin by suggesting that if we do one thing then that will lead to another, and before we know it we’ll be doing something that we don’t want to do.They conclude that we therefore shouldn’t do the first thing. The problem with these arguments is that it is possible to do the first thing that they mention without going on to do the other things; restraint is possible.
Slippery Slope Example“If you go out with that kind of guy, you will get pregnant and end up dropping out of college.”Either you stay in school or you won’t get a good job.
Red HerringThe red herring ...
With a view to employing logic appropriately we should be aware of logical fallacies we might commit. Some are common and unintentional , others are deliberate .Some are tricks to win an argument, others are simply immoral and should be avoided.

How to Make a Field invisible in Odoo 17Celine George
It is possible to hide or invisible some fields in odoo. Commonly using “invisible” attribute in the field definition to invisible the fields. This slide will show how to make a field invisible in odoo 17.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

In Odoo, the multi-company feature allows you to manage multiple companies within a single Odoo database instance. Each company can have its own configurations while still sharing common resources such as products, customers, and suppliers.
2. What are the parts of an
argument?
Example: I am really healthy now because I lost a lot of
weight.
What is the conclusion? What are the reasons provided?
Conclusion (The what): I am really healthy now
Reasons/evidence (The why): I lost lots of weight.
Assumption: This is the missing, or the invisible part of the
argument that must be true for the argument to make sense.
It links the evidence and the conclusion.
What is the assumption here?
That losing weight is healthy.
3. Example #2
Identify:
Conclusion
Reasons/Evidence
Assumption
Example: Barry Bonds is the greatest player in
baseball history because he hit more homeruns in
his career than anyone else.
4. Logical Fallacies
A fallacy is an incorrect argument based on a flaw in
reasoning. Often the mistake is in the assumption that links
the evidence and the conclusion.
What are the flaws in our previous two arguments.
1. I am really healthy now because I lost a lot
of weight.
2. Barry Bonds is the greatest player in
baseball history because he hit more
homeruns in his career than anyone else.
5. What’s wrong with this?
I used to eat a lot of spicy food and then I got the worst
stomach aches as a result. Turns out I had ulcers in my
stomach. If you keep eating all that spicy food then you’ll get
ulcers too.
First identify the conclusion and reasons and then the
assumption. Once done, try to explain what is wrong with it.
6.
7. Appeal to authority
Appeal to majority
Authority: Using an authority as evidence in your argument
when the authority is not really an authority on the facts
relevant to the argument.
Majority: A claim is accepted to be true simply because most
people are favorably inclined towards the claim
8.
9. Poisoning the well, ad hominem
attack
To prime the audience with adverse
information about the opponent from the
start, in an attempt to make your claim
more acceptable
11. Circular argument, begging the
question
The premises include the claim that the conclusion is true or
assume the conclusion is true.
The premise and conclusion are one in the same
13. Slippery Slope Argument
A person asserts that some event must inevitably follow from
another without any argument for the inevitability of the event
in question. In most cases, there are a series of steps or
gradations between one event and the one in question and
no reason is given as to why the intervening steps or
gradations will simply be bypassed
17. Strawman Argument
When a person simply ignores a person's
actual position and substitutes a distorted,
exaggerated or misrepresented version of
that position
18. Break down the following “argument.”
• What’s the conclusion/message?
• What are the reasons given?
• What is the assumption?
• What’s wrong with this reasoning?
19. Analysis
Conclusion: You should not trust what these experts have to
say on the topic of obesity.
Reason: They are fat.
Assumption: If you are guilty of something you cannot have a
valid opinion on the subject.
23. Appeal to emotion
Trying to use emotional reactions to make your argument
rather than reason. Trying to make someone feel sad, fearful,
or guilty (or other emotion) to make them believe what you
want.
26. What’s the relationship?
Adolf Hitler, Saddam Hussein, and Joseph Stalin all had
mustaches and killed lots of people. If we want to make
people safer, mustaches should be illegal.
Boys who act violently in school often play lots of violent
video games. Video games are the cause of violence.
27. Abortions and violent crime
In a very popular book, Freakonomics, the economists
identified a correlation between the abortion rate and crime.
As the number of abortions increased, the crime rate went
down. They assumed that there was a causal relationship.
They concluded, incorrectly, that babies who were more
likely to be aborted were the ones who were more likely to
grow up to be criminals.
29. Correlation does not equal
causation, False Cause
Two things may be correlated or related but it
does not mean that one thing caused the
other. Sometimes the causality is reversed and
sometimes there is no relationship at all. It is
also possible that the two phenomenon are
caused by a different third cause and
sometimes it is impossible to know the nature
of the relationship.
