Publilius Syrus (fl. 85–43 BC), was a Latin writer, best known for his sententiae. He was a Syrian who was brought as a slave to Roman Italy. By his wit and talent, Syrus won the favour of his master, who granted him manumission and educated him. He became a member of the Publilia gens. Publilius' name, due to the palatalization of 'l' between two 'i's in the Early Middle Ages, is often presented by manuscripts (and some printed editions) in corrupt form as 'Publius', Publius being a very common Roman praenomen.

Fear sometimes stops you from doing stupid things. But it can also stop you from doing creative or exciting or experimental things. It can cloud your judgment of others, and lead to all kinds of evil. The control and understanding of our personal fears is one of the most important undertakings in our life.
