Parrhesia concept from Aristotle

"Parrhesia is no longer an institutional right or privilege – as in a democratic city – but is much more a personal attitude, a choice of bios. This transformation is evident, for example, in Aristotle. The word "parrhesia" is rarely used by Aristotle, but it occurs in four or five places. There is, however, no political analysis of the concept of parrhesia as connected with any political institution. For when the word occurs, it is always either in relation to monarchy, or as a personal feature of the ethical, moral character. In the Constitution of Athens, Aristotle gives an example of positive, critical parrhesia in the tyrannical administration of Pisistratus. As you know, Aristotle considered Pisistratus to be a humane and beneficent tyrant whose reign was very fruitful for Athens. And Aristotle gives the following account of how Pisistratus met a small, landowner after he had imposed a ten percent tax on all produce:

... [Pisistratus] often made expeditions in person into the country to inspect it and to settle disputes between individuals, that they might not come into the city and neglect their farms. It was in one of the progresses that, as the story goes, Pisistratus had his adventure with the man of Hymettus, who was cultivating the spot afterwards known as "Tax-free Farm". He saw a man digging and working at a very stony piece of ground, and being surprised he sent his attendant to ask what he got out of this plot of land. "Aches and pains", said the man; "and that's what Pisistratus ought to have his tenth of". The man spoke without knowing who his questioner was; but Pisistratus was so pleased with his frank speech and his industry that he granted him exemption from all taxes.

So parrhesia occurs here in the monarchic situation.

The word is also used by Aristotle in the Nicomachean Ethics [Book IV, 1124b28], not to characterize a political practice or institution, but as a trait of the magnanimous man, the megalopsychos. Some of the other characteristics of the magnanimous man are more or less related to the parrhesiastic character and attitude".
