I have just finished reading the section of Plutarch’s De Moralia “On Curiosity.” The Greek word in question is a bit difficult to translate, so you also see “On Being a Busybody” used.
You can read it here: http://penelope.uchicago.edu/Thayer/E/Roman/Texts/Plutarch/Moralia/De_curiositate*.html
The thrust of the essay, is an argument against the sort of curiosity which feeds on knowing the failings of others. The gossipy nature, the uncovering of secrets, etc. So the essay both argues against this, showing how this nature is at the extreme leading to things like adultery; and it offers a therapy to undo these habits.
Plutarch suggests that we not read every bit of graffiti, or signage that we pass. That this little intrigue reduced our ability to study and descent important things, and trains the moral will into insinuating ourselves into things not our business.
He suggests that when we’re walking, we don’t peek in the doors of neighbors. We might also practice not checking out the workspace of our colleagues, and keeping our attention outside of their offices, cubes, or desks where we might work. Turn the gaze inward, to the self, and not to others.
Plutarch suggests that when a letter arrives, we delay opening it for a time. This can be true for email, push notifications for smart phones, and the other ten-thousand digital intruders of the day. We may even block those things into chunks: to check email once or twice a day, turn off the push notifications from Facebook, YouTube, or our favorite Stoic blogger, and instead only give a set amount of time to these things each day.
One of the things which Plutarch mentioned, is that the person who loves to uncover secrets also loves to share it. I suspect that the second part is easier to wrangle than the first. We might adopt an purposeful silence, not sharing the social tidbits which we might uncover. This will lead in time to a reduction in the former.
I suspect that part of the allure of sharing gossip is being perceived as the person “in the know.” Restricting such speech, then, will immediately curtail this feedback.
Plutarch remarks that the very people who seek out such knowledge are the ones we hide it from, and so the work of the gossip is twice as hard.
While not a Stoic work per se, this fits nearly into many philosophical settings. It’s short, and I recommend it to your reading.
It is important to remember how we train the moral will, and what small things lead to greater.
