Atheism: Logic & Fallacies

Atheism: Logic & Fallacies
[ Español / Spanish ] Introduction There is a lot of debate on the net. Unfortunately, much of it is of very low quality. The aim of this document is to explain the basics of logical reasoning, and hopefully improve the overall quality of debate. The Concise Oxford English Dictionary defines logic as "the science of reasoning, proof, thinking, or inference." There are many kinds of logic, such as fuzzy logic and constructive logic; they have different rules, and different strengths and weaknesses. What logic isn't It's worth mentioning a couple of things which logic is not. First, logical reasoning is not an absolute law which governs the universe. Second, logic is not a set of rules which govern human behavior. John wishes to speak to whoever is in charge. Unfortunately, John may have a conflicting goal of avoiding Steve, meaning that the reasoned answer may be inapplicable to real life. Arguments Many types of argument exist; we will discuss the deductive argument . valid or invalid Propositions

The NESS » How To Argue updated: June 2011 by Steven Novella, MD Arguing is one of those things most people do but few people do well. Many do not understand what a logical argument even is or how to do it correctly. Yet arguing is an essential skill of critical thinking. How we argue reflects how we think, how we evaluate our own conclusions, and how we challenge the beliefs of others. Even the very purpose of arguing is often misunderstood. The beauty of a logical argument is that it is, well… logical. Likewise, if two people have come to different conclusions about a factual claim, then one or both must be wrong. Keep in mind, this only works if the arguments are about factual claims, not subjective feelings or value judgments. An excellent example of this is the abortion debate. Structure of a Logical Argument Whether we are consciously aware of it or not, our arguments all follow a certain basic structure. Examine your Premises There are three types of potential problems with premises. Logical Fallacies

Why Physicist Michio Kaku Is Wrong About U.S. Science Students: It’s the Incentives, Stupid – Mike the Mad Biologist While physicist Michio Kaku is correct when he suggests that immigration has been an incredible boon for U.S. science, he's dead wrong when he claims that U.S. students are bad at science: The information revolution has a weakness, and the weakness is precisely the educational system. The United States has the worst educational system known to science. When I first came across Kaku's statement, I said to myself, "Crap. I part company with Kaku when he asserts that American students can't do science (or that there aren't enough of them - I'm not sure which he's arguing). It might be that many Americans don't go into science not because they are incapable (or lazy or damaged by their education), but because they're smart. I agree. But many students, even at supposedly elite institutions, lack this passion, and instead stumble into a career path that is convenient and lucrative: When my father finished Harvard Law School in 1948, he went to work at one of the best law firms in New York.

What is a logical fallacy? A "fallacy" is a mistake, and a "logical" fallacy is a mistake in reasoning. There are, of course, other types of mistake than mistakes in reasoning. For instance, factual mistakes are sometimes referred to as "fallacies". However, The Fallacy Files is specifically concerned with logical errors, not factual ones. A logical error is a mistake in an argument, that is, a mistake in an instance of reasoning formulated in language. There are two types of mistake that can occur in arguments: A factual error in the premisses. In logic, the term "fallacy" is used in two related, but distinct ways. "Argumentum ad Hominem is a fallacy." In 1, what is called a "fallacy" is a type of argument, so that a "fallacy" in this sense is a type of mistaken reasoning. Clearly, these two senses are related: in 2, the argument may be called a "fallacy" because it is an instance of Argumentum ad Hominem, or some other type of fallacy. History Sources: Why study fallacies?

A Review of B. F. Skinner's Verbal Behavior Preface Rereading this review after eight years, I find little of substance that I would change if I were to write it today. I am not aware of any theoretical or experimental work that challenges its conclusions; nor, so far as I know, has there been any attempt to meet the criticisms that are raised in the review or to show that they are erroneous or ill-founded. I had intended this review not specifically as a criticism of Skinner's speculations regarding language, but rather as a more general critique of behaviorist (I would now prefer to say "empiricist") speculation as to the nature of higher mental processes. My reason for discussing Skinner's book in such detail was that it was the most careful and thoroughgoing presentation of such speculations, an evaluation that I feel is still accurate.

Fallacies Dr. Michael C. Labossiere, the author of a Macintosh tutorial named Fallacy Tutorial Pro 3.0, has kindly agreed to allow the text of his work to appear on the Nizkor site, as a Nizkor Feature. It remains © Copyright 1995 Michael C. Other sites that list and explain fallacies include: Constructing a Logical Argument Description of Fallacies In order to understand what a fallacy is, one must understand what an argument is. There are two main types of arguments: deductive and inductive. A fallacy is, very generally, an error in reasoning.

Logical Fallacies How to Disagree March 2008 The web is turning writing into a conversation. Twenty years ago, writers wrote and readers read. The web lets readers respond, and increasingly they do—in comment threads, on forums, and in their own blog posts. Many who respond to something disagree with it. The result is there's a lot more disagreeing going on, especially measured by the word. If we're all going to be disagreeing more, we should be careful to do it well. DH0. This is the lowest form of disagreement, and probably also the most common. u r a fag!!!!!!!!!! But it's important to realize that more articulate name-calling has just as little weight. The author is a self-important dilettante. is really nothing more than a pretentious version of "u r a fag." DH1. An ad hominem attack is not quite as weak as mere name-calling. Of course he would say that. This wouldn't refute the author's argument, but it may at least be relevant to the case. DH2. DH3. This is often combined with DH2 statements, as in: DH4. DH5. DH6.

Logical Paradoxes Fallacy List 1. FAULTY CAUSE: (post hoc ergo propter hoc) mistakes correlation or association for causation, by assuming that because one thing follows another it was caused by the other. example: A black cat crossed Babbs' path yesterday and, sure enough, she was involved in an automobile accident later that same afternoon. example: The introduction of sex education courses at the high school level has resulted in increased promiscuity among teens. A recent study revealed that the number of reported cases of STDs (sexually transmitted diseases) was significantly higher for high schools that offered courses in sex education than for high schools that did not. 2. SWEEPING GENERALIZATION: (dicto simpliciter) assumes that what is true of the whole will also be true of the part, or that what is true in most instances will be true in all instances. example: Muffin must be rich or have rich parents, because she belongs to ZXQ, and ZXQ is the richest sorority on campus. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13.
