Seneca · On sophistical argumentation

Letters 45.1

You complain that in your part of the world there is a scant supply of books. But it is quality, rather than quantity, that matters; a limited list of reading benefits; a varied assortment serves only for delight. He who would arrive at the appointed end must follow a single road and not wander through many ways. What you suggest is not travelling; it is mere tramping.
