I really like these 20 lessons for the 20th century, especially defend institutions, beware of one-party states, investigate, make eye contact, and corporeal politics. But these two are my favs:

• Be kind to our language. Avoid pronouncing the phrases everyone else does. Think up your own way of speaking, even if only to convey that thing you think everyone is saying. Make an effort to separate yourself from the internet. Read books.
• Believe in truth. To abandon facts is to abandon freedom. If nothing is true, then no one can criticize power, because there is no basis upon which to do so. If nothing is true, then all is spectacle. The biggest wallet pays for the most blinding lights.

All in all, these are great lessons from a smart man who has studied tyranny and democracy for many years.
