When we look for propaganda, we have the obvious job of asking what messages are being propagated.

The liar wants to be believed, but lying undermines the foundation for credibility.

Since the time of Plato and Aristotle philosophers have had an interest in taking note of common fallacies in reasoning.

Exposure as a propagandist is fatal to the would-be persuader.

The special harm attaching to prior restraint is that the government can keep materials from reaching the public, so there can be no accountability, no judgment by the people that the power to suppress was wrongly exercised.

Any restrictions to freedom of expression will always open the door to possible others, because analogical reasoning can mount arguments showing why this or that class of objects is closely similar to those for which exceptions have been made.

In a general way, a major goal of the propagandist is to seek some kind of authoritative backing for the belief he or she is propagating.
