Sound reasoning is essentially a valid argument/claim with evidence to back it up. The argument needs to be written based on true premises and logical fallacies shouldn't be present. A sound argument typically requires an explanation to back up a clear message. A mix of ethos, pathos, and logos are present in a sound argument.
