This letter responds to criticism that its content is 'dry' and perhaps even boring, but defends its validity against a slanderous campaign waged by the media. The author criticizes impatience and hasty judgments of failure, emphasizing that successes achieved through power, violence, and lies are only temporary. He bases this on the idea that truth not only always prevails, but that its defeats are only temporary and 'as if defeats,' because it cannot be definitively defeated. Conversely, enemies of truth settle into the provisional, which explains their neurotic reactions. The author compares the struggle for truth to a war where defeats in individual battles are a condition for ultimate victory. He stresses the necessity of not using unclean means or tactics, even if it seems to give opponents an advantage, as exemplified by the disinformation about Charter 77 signatories in the GDR.
