## Key lines

> The great and fundamental article of the system (of the Persian theology) was the celebrated doctrine of the two principles; a bold and injudicious attempt of Eastern philosophy to reconcile the existence of moral and physical evil with the attributes of a beneficent Creator and governor of the world.

The core of Persian theology was the doctrine of two opposing principles, an ambitious but flawed effort to explain evil in a world created by a good God.

_This summarizes Gibbon's description of Zoroastrian dualism._

> Fasting and celibacy, the common means of purchasing the divine favor, he condemns with abhorrence, as a criminal rejection of the best gifts of Providence.

Zoroaster strongly rejected fasting and celibacy, viewing them as a sinful denial of God's blessings.

_This reflects Zoroaster's legislative concern for public happiness._

> There is a great variety of suggestions as to the proper reading here. There is evidently some corruption in the text.

Scholars have proposed many different readings, as the original text is clearly corrupted.

_This is a common textual note in the endnotes._
