17. There's only one standard for what constitutes a "valid" logical inference

Wed Sep 19, 2012, 06:24 PM

Sep 2012

A logical inference is "valid" if and only if it necessarily follows from the premises, in the sense that if the premises are true then the conclusion cannot be false. An argument is "sound" if the inference is valid and the premises are actually true. An argument is considered to be fallacious if it is either invalid or unsound (or both), and it isn't necessary to put a name to the fallacy involved.

You claim that Scott Peterson was convicted of murder "largely" because he acted in a guilty manner. If anyone is convicted of murder based solely on invalid logic, then I would suggest that I am not the one applying an inapplicable standard of proof, sir.
