why say it?
A thought-terminating cliché is a commonly used phrase, sometimes passing as folk wisdom, used to quell cognitive dissonance. Though the phrase in and of itself may be valid in certain contexts, its application as a means of dismissing dissention or justifying fallacious logic is what makes it thought-terminating.
In George Orwell’s novel Nineteen Eighty-Four, the fictional constructed language Newspeak is designed to reduce language entirely to a set of thought-terminating clichés. Aldous Huxley’s Brave New World society uses thought-terminating clichés in a more conventional manner, most notably in regard to the drug soma as well as modified versions of real-life platitudes, such as, “A doctor a day keeps the jim-jams away.” (from Wikipedia)
