Logical Fallacies
The Question That Begs Itself is - Am I using Fallacies ?
A logical fallacy is an error in reasoning that renders an argument invalid. Also called a fallacy, an informal logical fallacy, and an informal fallacy.
I have the honor of being in a college English class studying these and find them enlightening for my own sake let alone share with the world and my students.
The question that begs itself is...
Am I using these Logical Fallacies to prove my point, and if I am then indeed my point is invalid because I have used them.

15 Logical Fallacies
Ad Hominem Fallacy
Ad Hominem Fallacy
When people think of “arguments,” often their first thought is of shouting matches riddled with personal attacks. Ironically, personal attacks run contrary to rational arguments. In logic and rhetoric, personal attacks are called ad hominems. Ad hominem is Latin for “against the man.” Instead of advancing good sound reasoning, ad hominemsreplace logical argumentation with attack-language unrelated to the truth of the matter.
Straw Man
Straw Man
It’s much easier to defeat your opponent’s argument when it’s made of straw. The Strawman fallacy is aptly named after a harmless, lifeless, scarecrow. In the straw man fallacy, someone attacks a position the opponent doesn’t really hold. Instead of contending with the actual argument, he or she instead attacks the equivalent of a lifeless bundle of straw, an easily defeated effigy, which the opponent never intended upon defending anyway.
Appeal to Ignorance (argumentum ad ignorantiam)
Appeal to Ignorance (argumentum ad ignorantiam)
Any time ignorance is used as a major premise in support of an argument, it’s liable to be a fallacious appeal to ignorance. Naturally, we are all ignorant of many things, but it is cheap and manipulative to allow this unfortunate aspect of the human condition to do most of our heavy lifting in an argument
False Dilemma/False Dichotomy
False Dilemma/False Dichotomy
This fallacy has a few other names: “black-and-white fallacy,” “either-or fallacy,” “false dichotomy,” and “bifurcation fallacy.” This line of reasoning fails by limiting the options to two when there are in fact more options to choose from. Sometimes the choices are between one thing, the other thing, or both things together (they don’t exclude each other). Sometimes there are a whole range of options, three, four, five, or a hundred and forty-five. However it may happen, the false dichotomy fallacy errs by oversimplifying the range of options.
Slippery Slope
Slippery Slope
You may have used this fallacy on your parents as a teenager: “But, you have to let me go to the party! If I don’t go to the party, I’ll be a loser with no friends. Next thing you know I’ll end up alone and jobless living in your basement when I’m 30!” The slippery slope fallacy works by moving from a seemingly benign premise or starting point and working through a number of small steps to an improbable extreme.
Circular Argument (petitio principii)
Circular Argument (petitio principii)
When a person’s argument is just repeating what they already assumed beforehand, it’s not arriving at any new conclusion. We call this a circular argument or circular reasoning. If someone says, “the Bible is true because the Bible says it’s true"—that’s a circular argument. One is assuming that the Bible only speaks truth, and so they trust it to truthfully report that it speaks the truth. Another example of circular reasoning is, "According to my brain, my brain is reliable.” Well, yes, of course we would think our brains are in fact reliable if our brains are the one’s telling us that our brains are reliable.
Hasty Generalization
Hasty Generalization
Hasty generalizations are general statements without sufficient evidence to support them. They are general claims too hastily made, hence they commit some sort of illicit assumption, stereotyping, unwarranted conclusion, overstatement, or exaggeration.
Normally we generalize without any problem. We make general statements all the time: “I like going to the park,” "Democrats disagree with Republicans,” "It’s faster to drive to work than to walk," or "Everyone mourned the loss of Harambe, the Gorilla.”
Red Herring (ignoratio elenchi)
Red Herring (ignoratio elenchi)
A “red herring” is a distraction from the argument typically with some sentiment that seems to be relevant but isn’t really on-topic. Typically, the distraction sounds relevant but isn’t quite on-topic. This tactic is common when someone doesn’t like the current topic and wants to detour into something else instead, something easier or safer to address. Red herrings are typically related to the issue in question but aren’t quite relevant enough to be helpful. Instead of clarifying and focusing they confuse and distract.
Tu Quoque Fallacy
Tu Quoque Fallacy
The “tu quoque,” Latin for “you too,” is also called the “appeal to hypocrisy” because it distracts from the argument by pointing out hypocrisy in the opponent. This tactic doesn’t solve the problem, or prove one’s point, because even hypocrites can tell the truth. Focusing on the other person’s hypocrisy is a diversionary tactic. In this way, the tu quoque typically deflects criticism away from one’s self by accusing the other person of the same problem or something comparable. If Jack says, “Maybe I committed a little adultery, but so did you Jason!” Jack is trying to diminish his responsibility or defend his actions by distributing blame to other people. But no one else’s guilt excuses his own guilt. No matter who else is guilty, Jack is still an adulterer.
Causal Fallacy
Causal Fallacy
The Causal Fallacy is any logical breakdown when identifying a cause. You can think of the Causal Fallacy as a parent category for several different fallacies about unproven causes.
One causal fallacy is the False Cause or non causa pro causa ("not the-cause for a cause") fallacy, which is when you conclude about a cause without enough evidence to do so. Consider, for example, “Since your parents named you ‘Harvest,’ they must be farmers.” It’s possible that the parents are farmers, but that name alone is not enough evidence to draw that conclusion. That name doesn’t tell us much of anything about the parents. This claim commits the False Cause Fallacy.
cum hoc ergo propter hoc (Lat., “with this therefore because of this").
Fallacy of Sunk Costs
Fallacy of Sunk Costs
Sometimes we invest ourselves so thoroughly in a project that we’re reluctant to ever abandon it, even when it turns out to be fruitless and futile. It’s natural, and usually not a fallacy to want to carry on with something we find important, not least because of all the resources we’ve put into it. However, this kind of thinking becomes a fallacy when we start to think that we should continue with a task or project because of all that we’ve put into it, without considering the future costs we’re likely to incur by doing so. There may be a sense of accomplishment when finishing, and the project might have other values, but it’s not enough to justify the cost invested in it.
Appeal to Authority (argumentum ad verecundiam)
Appeal to Authority (argumentum ad verecundiam)
This fallacy happens when we misuse an authority. This misuse of authority can occur in a number of ways. We can cite only authorities — steering conveniently away from other testable and concrete evidence as if expert opinion is always correct. Or we can cite irrelevant authorities, poor authorities, or false authorities.
Equivocation (ambiguity)
Equivocation (ambiguity)
Equivocation happens when a word, phrase, or sentence is used deliberately to confuse, deceive, or mislead by sounding like it’s saying one thing but actually saying something else. Equivocation comes from the roots “equal” and “voice” and refers to two-voices; a single word can “say” two different things. Another word for this is ambiguity.
Appeal to Pity (argumentum ad misericordiam)
Appeal to Pity (argumentum ad misericordiam)
Argumentum ad misericordiam is Latin for “argument to compassion". Like the ad hominem fallacy above, it is a fallacy of relevance. Personal attacks, and emotional appeals, aren’t strictly relevant to whether something is true or false. In this case, the fallacy appeals to the compassion and emotional sensitivity of others when these factors are not strictly relevant to the argument. Appeals to pity often appear as emotional manipulation. For example,
Bandwagon Fallacy
Bandwagon Fallacy
The bandwagon fallacy assumes something is true (or right, or good) because other people agree with it. A couple different fallacies can be included under this label, since they are often indistinguishable in practice. The ad populum fallacy (Lat., “to the populous/popularity") is when something is accepted because it’s popular. The concensus gentium (Lat., “consensus of the people") is when something is accepted because the relevant authorities or people all agree on it. And the status appeal fallacy is when something is considered true, right, or good because it has the reputation of lending status, making you look "popular,” "important," or “successful.”

Recognizing Logical Fallacies
When you write arguments in college, you follow certain rules that ensure fairness. Not everyone who writes arguments is fair or thorough, however. Sometimes you will encounter arguments in which writers attack the opposition’s intelligence or patriotism and base their arguments on questionable (or even false) assumptions. As convincing as these arguments can sometimes seem, they are not valid because they contain fallacies —errors in reasoning that undermine the logic of an argument. Familiarizing yourself with the most common logical fallacies can help you to evaluate the arguments of others and to construct better, more effective arguments of your own.
Begging the Question
Begging the Question
The fallacy of begging the question assumes that a statement is self-evident (or true) when it actually requires proof. A conclusion based on such assumptions cannot be valid. For example, someone who is very religious could structure an argument the following way:
Circular Reasoning
Circular Reasoning
Closely related to begging the question, circular reasoning occurs when someone supports a statement by restating it in different terms
Weak Analogy
Weak Analogy
An analogy is a comparison between two items (or concepts)—one familiar and one unfamiliar. When you make an analogy, you explain the unfamiliar item by comparing it to the familiar item.
Although analogies can be effective in arguments, they have limitations.
Either/Or Fallacy (False Dilemma)
Either/Or Fallacy (False Dilemma)
The either/or fallacy (also called a false dilemma) occurs when a person says that there are just two choices when there are actually more. In many cases, the person committing this fallacy tries to force a conclusion by presenting just two choices, one of which is clearly more desirable than the other. (Parents do this with young children all the time: “Eat your carrots, or go to bed.”)
Politicians frequently engage in this fallacy. For example, according to some politicians, you are either pro-life or pro-choice, pro-gun control or anti-gun control, pro-stem-cell research or anti-stem-cell research. Many people, however, are actually somewhere in the middle, taking a much more nuanced approach to complicated issues.
You Also (Tu Quoque)
You Also (Tu Quoque)
The you also fallacy asserts that a statement is false because it is inconsistent with what the speaker has said or done. In other words, a person is attacked for doing what he or she is arguing against. Parents often encounter this fallacy when they argue with their teenage children. By introducing an irrelevant point—“You did it too”—the children attempt to distract parents and put them on the defensive:
Misuse of Statistics
Misuse of Statistics
The misuse of statistics occurs when data are misrepresented. Statistics can be used persuasively in an argument, but sometimes they are distorted—intentionally or unintentionally—to make a point. For example, a classic ad for toothpaste claims that four out of five dentists recommend Crest toothpaste. What the ad neglects to mention is the number of dentists who were questioned. If the company surveyed several thousand dentists, then this statistic would be meaningful. If the company surveyed only ten, however, it would not be.
Post Hoc, Ergo Propter Hoc (After This, Therefore Because of This)
Post Hoc, Ergo Propter Hoc (After This, Therefore Because of This)
The post hoc fallacy asserts that because two events occur closely in time, one event must cause the other. Professional athletes commit the post hoc fallacy all the time. For example, one major league pitcher wears the same shirt every time he has an important game. Because he has won several big games while wearing this shirt, he believes it brings him luck.
Non Sequitur (It Does Not Follow)
Non Sequitur (It Does Not Follow)
The non sequitur fallacy occurs when a conclusion does not follow from the premises. Frequently, the conclusion is supported by weak or irrelevant evidence—or by no evidence at all. Consider the following statement:
