Introduction to Logic is actually highly recommended. Or you can find a free introduction, called ForallX.

What kinds of deductive reasoning? I'd recommend practice and study of a specific application of deduction over reading about it in general.

I've played several games that require deduction:

  • Flow Free: Android iOS
  • Hashi: Android iOS
  • Slitherlink: Android iOS
  • Paint By Numbers/Hanjie: Web (can be printed for pencil and paper), Web
  • Electric Box: Web, requires Flash

    Other examples are Logic grids, Sudoku, and many others.

    I find that deduction is a skill that's easy to develop in a particular domain (like any of the above games), but hard to generalize. Playing the above games for fun, I've developed a better understanding of how to use proof by contradiction, but not much else.

    Those kinds of high-level ideas are probably best learned from a logic textbook like Introduction to Logic, but the abstract knowledge may not translate to practical skills without domain-specific practice and study.

>Your rule says that the exception shouldn't happen, period. If it does, then the rule needs heavy revision.
Ron Paul hired Amway spokesperson and author Doug Wead to serve as senior campaign adviser for $8,000 a month. Wead continues to run similar schemes to this very day with other members of Ron Paul's family, and Rand Paul himself recently hired Doug Wead as senior adviser as well.

No it doesn't. I don't subscribe to a philosophy that advocates for a utopian society. You throw up straw men like nothing I've ever seen before. Also, why are you so obsessed with Amway?

>Irrelevant. People are also voluntary voting for Donald Trump, in far higher number than they are for Rand.

Not irrelevant. You said that people can become billionaires by selling a product that 99% of people think is bullshit. Which is still completely false and you've yet to back up that claim. Also, Donald Trump has nothing to do with this argument. Please focus on defending the claim that a billionaire can make a product that 99% of people think are bullshit and still be a billionaire.

>Bernie Madoff.

He's serving 150 years in a federal prison. Let's keep it to billionaires that played within the law because in a free market economy he would still be rotting in prison.

>Estimated minimum wage effects on employment from a meta-study of 64 studies showed insignificant employment effect (both practically and statistically) from the minimum-wage raises supporting the Keynesian model. The most precise estimates were heavily clustered at or near zero employment effects (elasticity = 0).
47% of respected economics professors agree with the following statement, vs. only 14% who disagree: "The distortionary costs of raising the federal minimum wage to $9 per hour and indexing it to inflation are sufficiently small compared with the benefits to low-skilled workers who can find employment that this would be a desirable policy."
Mind you, 14% is the number of professors who claim that the costs outweigh the benefits. The number of professors who claim zero benefits in the first place is going to be far less than that.
And before you claim bias: This economic survey was conducted by the Chicago school, which is the most libertarian branch of economics out of the ones that use actual math.

I said the minimum wage causes unemployment, which you "disproved" in your first wikipedia article (with studies that showed absolutely no details regarding how the study was done) then you sent me the second article that has the majority of economists saying the exact opposite of what you first posted. The one's who disagree seem to be focusing on the word "noticeably" because a 9$ increase in minimum wage (as opposed to $7.25, now) would cause subtle increases in unemployment.

Regarding the "benefits of raising minimum wage" article. I never made a claim that it provided no benefits and I never made a claim about a $9 an hour minimum wage. All throughout history there have been slight increases in the minimum wage with fairly unnoticeable distortionary effects, but there are distortionary effects none the less including an increase in unemployment which you proved in your second article.

Again, more straw men.

>My argument is that you can be a billionaire even if 99% of the population thinks your product is bull shit. I've presented examples of this happening.

No you've said "amway" over, and over, and over again. Evil, Capitalist Amway provides over 21,000 people with decent enough paying jobs and sells nutritional supplements and different types of personal health care products. They don't "steal" money. Bernie Madoff is sitting in prison right now. Keep trying.

>I'm citing actual data and empirical examples. Meanwhile, you're claiming something that less than 14% of economics professors believe as a universal truth in economics circles, and you want to accuse me of living in an echo chamber.

I made no such claim. I made a claim that the minimum wage increases unemployment, which as you proved with your second article that it does.

Please stay on topic.

Also, read this when you get the chance and maybe we can keep this discussion from drifting off into 90 different directions with straw men whenever you can't prove a point you made.

Get a basic background in logic and statistics and their respective fallacies. This will give you the knowledge and tools you need to think critically of 99% of what you find in news media and websites. A good introduction to logic is Harry Gensler's Introduction to Logic textbook. A good guide to statistical fallacies and how to spot them is [The Black Swan by Nassim Taleb] (http://www.amazon.com/Black-Swan-Impact-Highly-Improbable-ebook/dp/B00139XTG4/ref=sr_1_1?s=books&ie=UTF8&qid=1421288487&sr=1-1&keywords=the+black+swan+taleb).

u/mavnorman · 1 pointr/TrueAtheism

It depends. But I'm glad you asked, for the following suggestions might also be helpful to others.

If I understand you correctly, you seem to think that pointing out fallacies is an efficient way to "fight the good fight". At least, that's my impression. Please correct me when I'm wrong.

Unfortunately, almost all the evidence points to a different direction: It's usually not very effective, because those committing the fallacy usually don't care much about a logical analysis of the situation, anyway. This does also apply to non-believers. Assuming all humans process information in two ways (see Kahneman's System 1 and 2), even atheists often seem to ignore their own system 2, because it actually takes effort to use it.

However, if you're looking for resources about fallacies, any good book on logic will help. One of the best one, I've been told, is "Introduction to logic" by Gensler. You may only need the first 5 chapters, because it becomes quite technical after that. Maybe, Amazon can help find a less technical book.

If, however, you're looking to persuade people, that's a completely different story.

Here, a very common recommendation is Cialdini's "Influence". You can research its contents easily online, so there's no need to buy it. Cialdini emphasizes six common areas to get people to agree with you.

I've looked at your comment history, so here's a short overview what you may want to change to be more effective:

  • Liking: People say yes to people they like. Being offensive to believers is thus unlikely to help you make your point.
  • Scarcity: People often want they don't think is hard to get. It's thus okay to say that we as atheists may indeed by the exception. It might help to say, you understand if your opponent is unable to understand your position.
  • Authority: It helps to have bookmarks, or notes, from authorities who believers respect (typically other believers).
  • Social Proof: It helps to have notes and bookmarks about being a non-believer is on the rise, generally speaking.
  • Reciprocity: People tend to return a favor. This is hard to apply online, but it may help offline.
  • Commitment: If people commit, verbally or in writing, to an idea or goal, they are more likely to honor that commitment. It's thus worth trying to get your opponents to agree to a certain set of principles. For instance, the fight about gay marriage was won by appealing to one of the most common principles among Americans: Freedom. A simple change of words (from the "right to marry" to the "freedom to marry") made a big difference.

    Hope this helps.

> Your idea of injustice is just what everyone else calls LIFE.

how cute

>Taxes pay for military bases and hardware. By your rationale, I should either be able to take the nearest nuclear sub out for a ride or I should get money for not being able to do that.

not for riding but you ought to be able to opt out of something like a nuclear weapon program. this is called direct democracy and it has been proven to work.

>The reason you shouldn't continue is not because I'm picking words. You shouldn't continue because you have a horseshit argument that you clearly cannot back up

i have backed up all my arguments.

you on the other hand is not making much sense

I suggest you read this book

> I told you I believe in an objective morality.

So you say.

> In your mind does the First Amendment consist of special
> exceptions provided for a group of offensive talkers?
> Protections for gun owners apply to everyone, the fact that you
> don't own a gun doesn't make you not protected for the same
> reason that you not saying things that are offensive doesn't mean
> that the first amendment doesn't apply to you.

See this is the problem, you think we are talking about the constitution.

This is about a bill that will hopefully prevent the extinction of elephants. But only if people can keep their eye on the ball. Only if every little special interest group doesn't get to put in their little ammendment to make it "better".

> Prove right now objectively that the golden rule is true.

Here's an introductory text book on logic which contains a proof of the golden rule. I'm sure this is better than anything I could come up with:

> I can easily prove that it is faulty and subjective. I like to be cut, therefore I can cut other people.

How smart you are. Its difficult to believe that so many people over so many years of human history couldn't come up with your simple yet irrefutable proof.

> Name some regulations that have been removed due to being ineffective.

The prohibition act of 1919 comes to mind.

>> Surely the people that have written this bill have spent more time thinking about what might work than the NRA minions of reddit

> Why would you assume this? Because you agree with it?

No, because it makes more sense that bill takes longer to write than it does to write a reddit response. Although this thread may yet prove me wrong.

u/InterstellarBlue · 1 pointr/learnmath

Check out Harry Gensler's Introduction to Logic. He is a really good writer - and everything is very clear.

u/simism66 · 1 pointr/askphilosophy

I really really like Gensler's book. The proof system he uses is extremely intuitive and easy.

u/JustinVx2 · 0 pointsr/worldnews

It doesn't and I didn't. I would recommend you to read this.

u/Namsaknoi4eve · 0 pointsr/worldnews

Here let me show you how a conversation works.

Person 1: This is that way

Person 2: No, this appears to be that way, but you're very statement contradicted what you said in the first place:

Person 1: Okay I'll show you why it's not a contradiction (OR) hmm maybe I was wrong.

You stated that Iran is an Islamic state that implements Sharia.

You said "Iran has executed women for attacking their rapist why can't you admit that Islam if not encourages but influences these actions"

I said: This can't be true, because the woman would not be able to attack her rapist if the Sharia was implemented, because the rapist would already be dead!

At this point you either: admit that Iran isn't practicing the Sharia properly, or you point to evidence that the rapist was put to death and thus never assaulted.

You're just jumping from topic to topic. How do you expect a conversation to ever end then?

Ok, so you just chose not to count all those previous CPUs, and built your argument on top of that.

You need one of these.
