"I have been further enlightened by the conversation and correspondence of some illustrious Italians, whom I would gladly name, were I not afraid of exposing them to danger"

This quote by Edmond About speaks with the power of discussion and correspondence in enlightening one's understanding. It recommends that About has actually had meaningful conversations and exchanges with some Italians, which have helped him to get a much deeper understanding of particular subjects. He is reluctant to call these people, however, as he is concerned that doing so could put them in threat. This implies that the conversations and correspondence were of a delicate nature, which the people included might have been at danger of persecution or retribution for their views. It is a testament to the power of interaction and exchange of ideas, and the nerve of those who participate in it, even in the face of danger.
