false reasoning, false arguments fallacious and deceptive reasoning and, by implication, based on evil intentions It may be difficult in some languages to speak of ‘false arguments,’ especially if the equivalent of ‘arguments’ is a verb meaning ‘to argue’ or ‘to discuss against someone.‘ One can, however, express the semantic content of ‘false arguments’ (as reflected in λογισμός[b]) by translating as ‘what people say when they argue, but their words are not true’ or ‘they argue with words that are not true.’
