Letter 40 — On the Proper Style for a Philosopher’s Discourse (§4)

“Besides, speech that deals with the truth should be unadorned and plain. This popular style has nothing to do with the truth; its aim is to impress the common herd, to ravish heedless ears by its speed; it does not offer itself for discussion, but snatches itself away from discussion. But how can that speech govern others which cannot itself be governed? May I not also remark that all speech which is employed for the purpose of healing our minds, ought to sink into us? Remedies do not avail unless they remain in the system.”
