All speech, written or spoken, is a dead language, until it finds a willing and prepared hearer.
— Robert Louis Stevenson

But be doers of the word, and not hearers only, deceiving yourselves. James 1:22
Bible hearers quote

To suppress free speech is a double wrong. It violates the rights of the hearer as well as those of the speaker.
— Frederick Douglass

The poets aim is either to profit or to please, or to blend in one the delightful and the useful. Whatever the lesson you would convey, be brief, that your hearers may catch quickly what is said and faithfully retain it. Every superfluous word is spilled from the too-full memory.
— Horace

The art of reasoning becomes of first importance. In this line antiquity has left us the finest models for imitation; I should consider the speeches of Livy, Sallust, and Tacitus, as pre-eminent specimens of logic, taste, and that sententious brevity which, using not a word to spare, leaves not a moment for inattention to the hearer. Amplification is the vice of modern oratory.
— hearers quotation by Thomas Jefferson
