"Calumny is only the noise of madmen"

Diogenes of Sinope was a Greek thinker who lived in the 4th century BC. He was understood for his wit and knowledge, and this quote is a perfect example of his insight. In this quote, Diogenes is saying that calumny, or harmful gossip, is absolutely nothing more than the ridiculous ranting of those who are not in their best minds. He is recommending that calumny is not to be taken seriously, as it is not based upon any reality or factor.

Diogenes' quote is a suggestion that we must not be swayed by the opinions of others, especially those who are not in their right minds. We need to rather concentrate on our own ideas and opinions, and not be affected by the words of those who are not in a position to make sound judgments. It is important to remember that calumny is absolutely nothing more than the noise of madmen, and need to not be taken seriously.
