11 This reply to your letter, my most loving brothers, I have dictated in all haste; and, overcoming my scruples, I have taken up my pen against a man whose ability I once eulogized. I would sooner, indeed, risk my reputation than my faith. My friends have placed me in the awkward dilemma that if I say nothing I shall be held guilty, and if I offer a defence I shall be accounted an enemy. Both alternatives are hard; but of the two I will choose that which is the least so. A quarrel can be made up, but blasphemy can find no forgiveness. I leave to your judgment to discover how much labour I have expended in translating the books On First Principles; for on the one hand if one alters anything from the Greek the work becomes less a version than a perversion; and on the other hand a literal adherence to the original by no means tends to preserve the charm of its eloquence.
