Divinatio in Q. Caecilium

Those things which I am speaking of are very important, believe me. Do not you despise this either; everything must be related, and demonstrated, and explained; the cause must be not merely stated, but it must also be gravely and copiously dilated on. You must cause, if you wish really to do and to effect anything, men not only to hear you, but also to hear you willingly and eagerly. And if nature kind been bountiful to you in such qualities, and if from your childhood you had studied the best arts and systems, and worked hard at them;—if you had learnt Greek literature at Athens, not at Lilybaeum, and Latin literature at Rome, and not in Sicily; still it would be a great undertaking to approach so important a cause, and one about which there is such great expectation, and having approached it, to follow it up with the requisite diligence; to have all the particulars always fresh in your memory; to discuss it properly in your speech, and to support it adequately with your voice and your faculties.
