It is not [...] to wonder if the memory of the Achaemenids has completely disappeared from the minds of the people who did not know them and did not … - Italo Pizzi

The morality taught by the 'Avesta', beyond and above its theological, dogmatic, ritual precepts, is still a very high and pure morality that rightly places Zoroastrianism among the most elected religions in the world. The same threefold precept of never sinning in thoughts, in works, in words, which is also among the precepts of Christianity, encloses in its rigidity and summarizes every other precept that is intended to guide man down here. The greatest virtues that, moreover, were recommended not also by the <nowiki>'</nowiki>Avesta', but also by the law and custom common to all the Iranians, were justice, charity, generosity, piety, the horror of lying.

We, long bred in the ideas of classical culture, because we know that the Greeks defeated the Persians at Marathon, at Thermopylae, at Salamis, we also aged ourselves to consider these people as a bunch of cowards taken to the slaughter by the ambition of a tyrant, while it is also known that they, in those battles, fought as va Herodotus himself makes it, with praise, beautiful and open testimony, nor, bear in mind that, they were all Persians or Iranians the soldiers that Darius and Xerxes were then with them; he was, on the other hand, an infinite bevy, ill-ordered, of distant and very different people. Alexander, it is true, took the kingdom from Dario Codomanno, but and Darius and his people, while yielding, yielded as valiant; and the Arabs who in the seventh century of our Era invaded Iran and destroyed the ancient empire in 650, certainly did not enter without a blow injuring the rich and glorious country, even if the kingdom was torn.

Whatever it may, it is a well-ordered and engineered system of religion that, like Mosaism, Christianity and Islamism, proceeds from the preaching and fruitful work of one person.
