| * If a large majority in a particular reference group G accepts A as true (false), then there exists a defeasible presumption in favor of (against) A * A large majority accepts A as true (false). * Therefore, there exists a presumption in favor of (against) A This form of the argument might use polls or statistics meant to measure public opinion. This argument may or may not accurately reflect a real world state, but the fact that so many people commit to it, gives it a presumption that it does accurately reflect a real world state. (Walton, Reed, Macagno. 125) Critical Questions regarding the argument scheme. 1. Is it really the case that a large majority of the particular reference group accepts A as true? 2. Is there any other available evidence that would support the assumption that A is false? 3. What reason is there for thinking that the view of this large majority is likely to be right? |
On the left is a picture of a type of argument diagram. Douglas N. Walton uses the araucaria program, but I don't use it as much as I use this type of form mixed with flowcharting conventions by hand. I use the software sometimes, but I mostly do diagrams using the tools I already know. Here are a couple of links to PDF Documents by Walton explaining what diagramming arguments is good for.

| Depending on preferred classification style, it can be a subcategory of Ad Populum or a subcategory of Source-based Arguments. Ad Populum arguments are inherently weak and prone to exploit prejudice. They are typically categorized as fallacies but in many instances they can be reasonable arguments and the best kind of evidence available to make a rational decision (Walton, Reed, Macagno. 121). |
| Major Premise: a person a is in a position to know about things in the domain of a subject which contains proposition P. Minor Premise: a asserts that P is true (or false). Conclusion: P is true (or false). Critical Questions about the argument 1. Is a in a position to know whether P is true (or false)? 2. Is a an honest (trustworthy, reliable) source? 3. Did a assert that P is true (or false)? Reference for this example in the book Argumentation Schemes Douglas Walton, Legal Argumentation and Evidence.

Explanation Information that is supposed to indicate the origin, cause, meaning, or significance of an event or other phenomenon.
Example: "She's the best tennis player on the team because she has had better coaching, is in better shape, and practices a lot more than anyone else"
Argument Information that is supposed to establish that a proposition is true or otherwise worthy of belief or acceptance.
Example: "She consistently defeats all her teammates, so she's the best tennis player on the team."

IT IS because the Catholic Church opposes embryonic stem cell research that xenotransplantation remains the only option for many researchers and sufferers of serious diseases (Letters, 12/12).
Such research offers the potential to one day be able to grow tissue to replace diseased organs, hence curing many of these diseases and significantly reducing the number of animals killed for medical research.
We can only hope that eventually religious organisations will stop using their interpretations of ancient texts to hold back new forms of scientific research. In the meantime, the suffering of human and animals continues unabated.

Father Federico Lombardi, the pope's spokesman, said it's not realistic to think the Vatican can ensure 100% security for the pontiff because he is regularly surrounded by tens of thousands of people for his weekly audiences, services, papal greetings and other events.
"It seems that they intervened at the earliest possible moment in a situation in which 'zero risk' cannot be achieved," he said of Vatican security officials. They will nonetheless review the episode and "try to learn from experience," Lombardi said.

The sacrifices of the Bible were offered not only to atone for sins but also as free will offerings to celebrate some joyous event, and as holiday offerings for the three biblical pilgrim festivals of Passover, Shavuot (Pentecost) and Sukkot (Tabernacles). Each of these three holidays was called, in Hebrew, a hag. The Muslim pilgrimage to Mecca called the Haj takes it name from this word.

Some theologians consider such animal sacrifices spiritually primitive and in general, I, along with every single animal, agree with them. Although animal sacrifice is arguably the oldest religious ritual on earth, it's based upon a very dubious belief--that the death of an animal can correct your own moral failings.
...
The rabbis introduced a daring change in Jewish worship - replacing every sacrifice with a prayer from a newly created prayer book. The prayer times were the same times as the sacrifice times, but no blood was spilled.
...
This change was made necessary by historical events but had enormous impact on Judaism and the newly emerging religion of Christianity. Surrogate atonement through animal sacrifice was basically abandoned in favor of the direct and ethically superior command of confession and personal apology to anyone you had hurt. Sins were human acts that needed to be fixed by human actions, inspired, of course, by God's commands to love our neighbors as we love ourselves.

Give this problem a shot before you keep reading, but don't feel badly if you get it wrong.
Bob is in a bar, looking at Susan. But she is looking at Pablo. Bob is married. Pablo is not.
Is a married person looking at an unmarried person? The answer could be (a) yes, (b) no or (c) cannot be determined.
Roughly 80 per cent of people choose (c), but it is not the correct answer, says Keith Stanovich, a professor of human development and applied psychology at the University of Toronto.
He studies why smart people do stupid things - or, in more scientific terms, how intelligence is distinct from rationality. His work offers insight into important cognitive abilities that are not measured by IQ tests. It also suggests that deficits in real-world reasoning can be corrected, whether in adults or in children.
He says most people get the Bob-Susan-Pablo problem wrong because they tend to be "cognitive misers" - they put as little mental effort as possible into solving a problem. In this case, they quickly jump to the conclusion that they don't have enough information rather than making the effort to see if they do.

The findings may illuminate reasons why some people form false beliefs about the pros and cons of health-care reform or regarding President Obama's citizenship, for example.
The study, "There Must Be a Reason: Osama, Saddam and Inferred Justification" calls such unsubstantiated beliefs "a serious challenge to democratic theory and practice" and considers how and why it was maintained by so many voters for so long in the absence of supporting evidence.
Co-author Steven Hoffman, Ph.D., visiting assistant professor of sociology at the University at Buffalo, says, "Our data shows substantial support for a cognitive theory known as 'motivated reasoning,' which suggests that rather than search rationally for information that either confirms or disconfirms a particular belief, people actually seek out information that confirms what they already believe.
"In fact," he says, "for the most part people completely ignore contrary information".

The results of this study, according to the authors, advance the understanding of brain cell mechanisms that underlie decision making by coupling for the first time the mechanisms that lead to decision formation and the establishment of a degree of confidence in that decision.
"Our findings suggest that when the brain embraces truth, it does so in a graded way so that even a binary [yes/no, true/false, left/right] choice leaves in its wake a quantity that represents a degree of belief. The neural mechanism of decision making doesn't flip into a fixed point, but instead approximates a probability distribution."
