7. Dr Smith, who is a well-known doctor, says that abortion is not immoral.
8. Therefore, abortion is likely not immoral.



This is an argument from authority fallacy. Being a well-known doctor doesn't make you an expert on the morality of abortion. Thus, appealing to the authority of Dr Smith as a reason to accept the conclusion is an error. But this error depends on whether or not Dr Smith is actually an expert on the topic, which does depend on the meaning of the constituent terms in the argument - hence making the error not a formal, but informal error (for instance, some appeals to authority are not errors at all).

I'm not sure what point you are making by switching the order of the premises in the example in my previous post. You are using these terms in non-standard ways from my own experience in logic.
I really don't understand why you make a post not only affirming my opinions, but acting like you are somehow original in doing so.

Jeez, thanks for explaining what I meant back to me.

A big one that you seem to be missing. Big clue: I didn't switch premises. I switched a premise for an argument.

You are using these terms in non-standard ways from my own experience in logic.
Please relate your own experience in logic.

You made this claim:

I have been arguing that this definition is incorrect. The meaning you claim here for "fallacy" is only true of formal fallacies, but not of informal fallacies. I demonstrate this by providing a counterexample - providing an ad hominem argument that would generally be considered fallacious, but where the conclusion still follows from the "precepts." Thus, either the argument I presented isn't fallacious, it isn't valid, or your definition of "fallacy" is incorrect.

If I've misunderstood your position, and you actually agree with me, good.

Ok - you are obviously more knowledgeable than I on this topic, so I am inclined to defer to your views rather than stubbornly stick with mine, but I don't understand how in one breath you can say "a fallacy is an error in reasoning" and in the next offer an example where the *reasoning* is entirely valid?

I think your view is more charitable than the majority of atheist posters in this forum. Based on the types of antagonism expressed towards and about religion and religious adherents, it would seem that searching itself is perceived negatively by that population.

Quote:
For instance, I think none of the philosophical defenses of morality I'm aware of rise above plausibility. So I would hesitate to say that I believed that, say, consequentialism is true. But I do think of morality as forced - inaction is itself a morally significant act in most systems of morality. Thus, I might say that I am a consequentialist as a matter of moral commitment, without really thinking that I know enough to say I believe it to be true.
This is where I would start to lean in a bit to try to discuss something like "behaving as if X is true." This is different from some sort of mere abstract assent to consequentialism, in which you assert a belief but it has no practical application in how actually analyze your decisions. So if you take action X intending/expecting a positive outcome, but in reality the outcome is negative, your ability to intellectually/emotionally reckon that event as being a moral ill because your consequentialist commitment (instead of another analysis that takes into account all of the good things you had hoped would happen as a result of your action) would then stand as a way to measure your commitment to the belief.

This is a little bit of a stretch for a philosophical commitment of this type, as it's merely an analytic framework. But if you were to assent to something additional, such as a desire to make morally good decisions, then one might have a more robust way of measuring your philosophical commitment by also comparing your actual decisions with the abstract analysis.

Quote:
I can understand someone being a Christian in this commitment sense (e.g. Christian existentialism), but I don't see how the contingencies of human decision-making make a difference in whether a god actually exists. Thus, this seems to have little to do with the truth of the matter.
You might be correct under the view of human behaviors as merely being based on outcomes. The assessment becomes far less clear if you also view human behaviors in light of motivations and truth.

For example, you can take two identical situations of one person treating another person well. One might be doing it from a place of genuine care and concern for the other, and the other may be doing it with the future intention of doing something exploitative.

I agree that in the consequentialist perspective, these are the same as long as the point of future manipulation doesn't happen because the fact would be that the other person was only treated well.

But if one peels back that first layer and can see intent, it becomes less clear
that we should actually view these behaviors as being the same.

With regards to "truth" I would argue that motivations that are grounded in truth should fare generally better than those that are not. And if (for example) it is true that people are made in God's image and that a consequence of this is that people should be treated well, then it makes a moral difference between treating people well for that reason or treating them well because you intend to exploit the relationship in the future.

In this way, I would say that a purely consequentialist perspective is unnecessarily limiting in the same way that a goddidit explanation is unnecessarily limiting. It doesn't necessarily make the position right or wrong (or true or false) to adopt that position, but there are consequences to it.

Quote:
I view rationality as a tool. Thus, I would rather say that rationality is a function of a goal than a starting place. This means that if we talk about rational beliefs, we can do so only within the context of specific goals for having beliefs. I mostly keep to the goal of believing what is true and not believing what is false. For that goal, believing in the existence of the gods of religion seems irrational. However, I recognize that other people have different goals for belief, and that these other goals can rationally lead to a belief in god and religion. Nonetheless, I still reject these other goals as worthy of guiding belief.
In mathematical terms, it's possible to get entirely different universes of conclusions based on different assumptions, even if the general goals are the same. The classic example is Euclidean and Non-Euclidean geometry. You can have your goal as "understand the properties of triangles" in both situations and end up with two different sets of beliefs about triangles by just changing the assumptions and not changing the motivation.

So I don't reject that motivation matters (because the types of things you would end up believing would depend on the types of questions that motivate the pursuit), but it seems to me that assumptions matter more because these are the things that actually separate distinct belief systems from each other.

Probably, your question is grounded in the assumption that the purpose of prayer is to get God to change something. This would be a far too narrow understanding of Christian prayer.

Deductive validity refers to only one aspect of reasoning - that relating to the logical form of deductive arguments. When we make an error of reasoning in deductive logic, we are making an invalid argument. However, deductive logic is not the only kind of reasoning we do. We also make inductive arguments, scientific arguments, etc. The errors we make with these arguments are not typically that they are deductively invalid (eg it is typically not a useful criticism of a scientific theory that the conclusion doesn't follow necessary from its premises). The informal fallacies list some of the typical errors of reasoning human make that are not just a matter of the logical form of deductive arguments. So when you say that "fallacy" means that the conclusion doesn't necessarily follow from the premises, you are defining the broader term "fallacy" by the meaning of a subset of, "formal fallacy."

Because it would mean that all religions that postulated things happened because God decided to do something are erroneous. Yet it would also make it erroneous to say that deism is essentially the same as atheism.

Because if people believed deism plus afterlife they would spend more time making sure they do the right thing and less time taking comfort from the thought that they can do wrong and then confess their way out of it.

I sort of get where you're coming from, but I'm getting a bit lost in the verbiage.

I am looking at this as follows:

1. We have premise (or premises)
2. We have some logical thought/argument
3. We have a conclusion

An example might look like this:

1. All fronds are green
2. Spink is a frond
3. Spink is green

This is formally valid.

Another example might look like this:

1. All fronds are green
2. Spink is green.
3. Spink is a frond.

This is formally invalid.

I'm hoping we agree up to this point. Now for some more interesting examples.

1. All fronds are green
2. Spink claims to be a frond
3. Spink is green

Your view?

1. Spink claims to be a frond
2. All fronds are green
3. Spink is green

Your view?

I suspect this is where you are getting confused. The right way to put this is:

We have premises
We have a conclusion.

We also use rules of inference to see if the conclusion follows validly from the premises, but the rules of inference are not themselves part of the argument. You can expand on what you mean by "Logical thought/argument," but it looks confused to me. Validity (which is what is generally meant by "logical") is a property of arguments, not statements/thoughts/propositions. An argument, by definition, requires at least two statements (even if they are identical). So in none of the following examples is (2) a "logical thought/argument" - instead, in all these arguments (2) is a premise.

These are both identical invalid arguments. The order of the premises (i.e. (1) and (2)) doesn't affect the logic of the argument. This argument is invalid because it can be true that Spink claims to be a frond while not actually being a frond.

My guess is that you were at some point taught Aristotle's syllogistic logic. Aristotle developed a theory of logical inference which applies to certain specific kinds of arguments involving categorical statements with what he called "major" and "minor" terms (and correspondingly a major and minor premise). There is a convention about how to order these premises, but this order has no bearing on the logic of the argument itself. However, Aristotle's syllogistic is mostly just a historical curiosity today (except in Catholic schools).

I've criticized you for making up facts, being bad at recalling the trajectory of the conversation, presenting bad arguments, being a hypocrite, willful misrepresentation of others, failing at identifying a true Scotsman fallacy, coming up with random objections, conflating language, being unwilling to admit error, being delusional, and several other things... but I'm pretty sure I haven't criticized your tone. I could be wrong. There's a lot to criticize.

Edit: Not knowing what words mean, being anti-science when it doesn't conform to your beliefs...

Quite the cacophony of criticisms, there.

Ironically, the only thing I regret in my interactions with you in this thread is tone.

Thank you - having read through this, I now understand where I was thinking about things incorrectly. You are quite right that (2) in my examples is not an argument, and, looking back at it, I have no idea why I ever thought it was. In fact, looking back in that light, my whole previous post is quite idiotic.

There's no irony there. Since you are so nonchalant when do things like reject scientific literature, misrepresent others, and make literally false statements, it should really be no surprise to anyone to discover that the location of your head is adjacent to the sigmoid colon.

Aaron, back on the topic of religiosity and logic, here is a quote from newly elected Montana congressman Greg Gianforte, who has been in the news recently due to his proclivity for body-slamming reporters.

Quote:
There’s nothing in the Bible that talks about retirement. And yet it’s been an accepted concept in our culture today. Nowhere does it say, ‘Well, he was a good and faithful servant, so he went to the beach.’ It doesn’t say that anywhere.

The example I think of is Noah. How old was Noah when he built the ark? Six hundred. He wasn’t like, cashing Social Security checks, he wasn’t hanging out, he was working. So, I think we have an obligation to work. The role we have in work may change over time, but the concept of retirement is not biblical.
Oh yeah, he is a YEC as well.

Now, the fact that he just got elected, means that some significant % of people in Montana would read the above and think that it is a reasonable view to hold. Are these people being reasonable or logical in your view?
