Seneca · On the dangers of association with our fellow-men

Letters 103.4

And what may you attain by living such a life? Not necessarily freedom from harm at their hands, but at least freedom from deceit. In so far, however, as you are able, take refuge with philosophy: she will cherish you in her bosom, and in her sanctuary you shall be safe, or, at any rate, safer than before. People collide only when they are travelling the same path.

Seneca, Letters to Lucilius 103.4, translated by Richard Mott Gummere
