“There [is] no little vigour and force added to words, when they are delivered in a neat and fine way, and somewhat out of the ordinary road, common and dull language relishing more of the clown than the gentleman. But herein also affectation must be avoided; it being better for a man by a native and clear eloquence to express himself, than by those words which may smell either of the lamp or inkhorn.”

Context: There are many seeming contradictions and even obscurities in the innumerable writings of the church fathers. Our respect for their authority should not stand in the way of an effort on our part to come at the truth. The obscurity and contradictions in ancient writings may be explained upon many grounds, and may be discussed without impugning the good faith and insight of the fathers. A writer may use different terms to mean the same thing, in order to avoid a monotonous repetition of the same word. Common, vague words may be employed in order that the common people may understand; and sometimes a writer sacrifices perfect accuracy in the interest of a clear general statement. Poetical, figurative language is often obscure and vague.
Not infrequently apocryphal works are attributed to the saints. Then, even the best authors often introduce the erroneous views of others and leave the reader to distinguish between the true and the false. Sometimes, as Augustine confesses in his own case, the fathers ventured to rely upon the opinions of others.

Context: What is it that we humans depend on? We depend on our words... Our task is to communicate experience and ideas to others. We must strive continually to extend the scope of our description, but in such a way that our messages do not thereby lose their objective or unambiguous character … We are suspended in language in such a way that we cannot say what is up and what is down. The word "reality" is also a word, a word which we must learn to use correctly.

Context: To be quite candid — and what I am going to say now is something I have never said before, and I hope that it provokes a salutary chill — I know more than I can express in words, and the little I can express would not have been expressed, had I not known more.

Context: The English language may hold a more disagreeable combination of words than "The doctor will see you now." I am willing to concede something to the phrase "Have you anything to say before the current is turned on?" That may be worse for the moment, but it doesn't last so long. For continued, unmitigating depression, I know nothing to equal "The doctor will see you now." But I'm not narrow-minded about it. I'm willing to consider other possibilities.
