logic

I've been thinking about how (hypothetically) I might introduce the topic of skepticism to young people, and thought a good starting point would be to describe the thought process when a skeptic evaluates a claim. Speaking for myself, I usually ask a few questions: 1. Do I care whether the...

In the thread There is no evidence for God, poster case#46cw39 used the terms "inductive" and "deductive" in a manner I thought to be incorrect, so I challenged him. He responded, and yy2bggggs chimed in on my side. For the record, SumDood also challenged case#46cw39's definition, but on...

If you're not familiar with the Liars Paradox (which I will refer to as "LP" in this thread), a quick read on google should make it clear. The paradox is as follows: "this statement is false". This is linguistically interesting, since it leads to an eternal regression where the statement ends...

Since my last thread on this didn't go as well as I hoped, I thought I would just make another one and type directly what a logic major replied to me with. I sent him the standard illogical and contradicting attributes of God. His reply (with mine in quotes): I think this is an error like the...

Lately, I've encountered much opposition towards Richard Dawkins, but the suprising thing about this is that it's mostly coming from atheists. Even my good friend who is probably the most hardcore atheist I know said that he cannot stand the illogic and weak arguments of Dawkins and just wishes...

"Proving Einstien wrong" - or: "alternative" ideas and observation Hi, this is more of a "hypothetical" problem i've encountered. The question is: with the amount of knowledge about the world available today, can anyone seriously still make a claim of having "disproved" general relativity, or...

Is there any valid logical disproof of the tri omni God? I know that there isn't a logical proof of one, but I want to hear arguments that try to disprove a God logically. Btw, I'm an atheist.

Some excellent debunking over at cosmicvariance today Check it out here - don't worry about the URL title, it should crush the hope of out any person susceptible to reasoned argument who is still hoping that science has left the woo a little wiggle room, especially if they think that invoking...

So at my workplace about a month ago they had me calculate an hourly read to see if we were either ahead, even, or behind in total sales. So one day my manager wanted me to calculate the hourly read since no one bothered to do it and we were about halfway through the new hour. She also asked me...

We have two possibilities; 1. Man is contributing to Global warming. 2. Man is not contributing to Global warming (or there is none.) We have two courses of action; 1. Reduce greenhouse emissions. 2. Burn, baby, burn! And four outcomes; 1. If we are not contributing to it, and we...

Can you prove the rules of logic somehow? If there is no proof for logic, how can one be so sure in it?

I am multi-cultural, trilingual, and consider myself to be a person of slightly above average intelligence (115 IQ, nothing special). My whole life I have always felt as if the education system was letting me down; I was never challenged and easily lost interest in my classes even through honors...

Check me on this, because I want to make sure I have the right line of thinking. Conspiracy theorists blame the NWO, or the government, or who knows what mysterious organization for crimes against the population. They cite previous examples of prior planning like the PNAC document, military...

I was browsing some of my archived files and ran across the following. I have no idea where I got it or who wrote it, but it's amazing how many of these I've seen used here:

I'm reading Dawkins' "The Ancestor Tale". In the prologue, he notes - I'm a little fuzzy on the how and why of his reasoning. Any help?

From the Dawkin's Thread Ah, the age old question, "Where is fancy bred? In the heart, or in the head?" --Willy Wonka and apologies to Shakespeare's Merchant of Venice but I prefer Wonka's version. Is logic not possible without a soul (homunculus) or at least some other force or something else...

Creationists always use examples from nature where everything works "perfect" (like, ray fishes, which are almost ideally adopted to live in conditions they do) as an evidence for God: "look, how perfect it is! it's definitely the work of Higher Force!". But when somewhere something goes not...

Articulett started this in the Atracttive thread... "Suppose you're on a game show, and you're given the choice of three doors. Behind one door is a car, behind the others, goats. You pick a door, say number 1, and the host, who knows what's behind the doors, opens another door, say number 3...

6/6/06 could be a devil of a day — or not Everyone knows that the rapture will NOT occur today because Jesus said no one knows that it WILL occur today? :confused:

Amazing!!! My former teacher of Astrology,Master Joseph Yu of Torobnto,who has a degree in maths, said that he once wanted to prove astrology is superstition, but after doing some charts he concluded that «astrology is logical». He then became a master.No comment!!:p

This is a logic question, not a scientific one hence I put it on this board. I found it interesting, and I'm sorting through it-- looking for some :) "wholesome" :) feedback. The argument is presented by Alvin Plantiga and can be found at length here...

Logic The branch of philosophy that deals with the formal properties of arguments and the philosophical problems associated with them. The use of critical thinking, particularly binary yes/no thinking and inductive/deductive reasoning, as a means of testing ideas and debate. Reason In...

Look at this website on Christian logic: http://www.christianlogic.com/forums/index.html Here's their rules: This discussion forum is designed primarily for evangelical Christians and the board as a whole subscribes to Aristotle’s formalization of logic. If you are not an evangelical...

Remind you of anyone you've seen on here?

I was asked the question: I have a feeling that says NO, but am I right?

Satan has a very complex plan. I will call this plan the plan of Damnation which is the opposite of God's plan of Salvation. The plan of Damnation: First, Satan makes your mind think a certain way. In today's world we see a revolution in rationalism. We see people are getting more and more...

In a book I am reading is the following: "Mathematical proofs are merely matters of form, with the question of meaning put aside....axioms are strings of uninterpreted symbols....any interpretations of the symbols play no role at all in deducing theorems." My question is not a challenge of...

Logic is a subject area and an important ingredient in any logical subject area. What are some actual tasks, projects, assignments, exercises, problems, or activities that are related to logic? I am not looking to see what sorts of problems are assigned to credit-seeking students by...

Is chess, more than other board games, a game of logic? It seems to me that chess is simply an extremely complicated and dynamic game based on a very simple set of rules. In other words, it is a game of rules rather than a game of logic. Are there principles of logic that can be well...

Under what circumstances is logic the correct tool to use to make a decision? When is emotion more correct to use to make a decision? Under what circumstances are "appeals to emotion" the correct argument? IndigoRose
