Truth
Fallacies do not cease to be fallacies because they become fashions. (G. K. Chesterton, 19th-20th century British apologist)
The more often we hear something that at first seems strange, the more acceptable it may become. Yet, falsehood doesn’t become truth by its repetition. Some TV commercials are repeated so often that they become commonplace to us, and no matter their validity, they may soon become acceptable to the unwitting observer. Beware!
An honest witness tells the truth, but a false witness tells lies (Proverbs 12:17).
