[edit] Factual Accuracy Dispute
This article has the definitions for "cogent" and "strong" backwards. A strong argument is one in which the premises, if true, would make the conclusion probable. A cogent argument is one that is strong and has all true premises. When compared with a deductive argument, "cogency" is analogous to "soundness." I'm a bit busy right now to make the necessary changes, but will revisit the article tomorrow if no one does it first.Simoes 02:37, 2 November 2005 (UTC)
- Since the Wikipedia article on Inductive logic does not specify, I would be interested to see a source on this. --Jdz 04:52, 28 December 2005 (UTC)

- I finally got around to making the changes. I googled for sources and came up with a page from Carnegie Mellon University's philosophy department website [1]. --Simoes 21:27, 28 December 2005 (UTC)
[edit] Begging the Question
1. Water freezes at 0 degrees Celsius 2. Therefore, water freezes at 0 degrees Celsius
"is a sound argument, because it is a valid argument, all of its premises are true, and it has a true conclusion, but it isn't good, because it doesn't prove anything and is a case of begging the question."
How is this "begging the question"? It's just a tautology (A implies A). --Jdz 04:52, 28 December 2005 (UTC)

- I nixed this material because question begging is a feature of a deductive argument, not an inductive one. However, the fallacy of begging the question is where an argument contains in its premises the conclusion. This, of course, involves a tautology.--Simoes 22:22, 30 December 2005 (UTC)
"question begging is a feature of a deductive argument, not an inductive one" this is probably not true.
