-Señor- respondió Sancho-, que el retirar no es huir, ni el esperar es cordura, cuando el peligro sobrepuja a la esperanza, y de sabios es guardarse … - Miguel de Cervantes

For me alone Don Quixote was born and I for him. His was the power of action, mine of writing. Only we two are at one, despite that fictitious and Tordillescan scribe who has dared, and may dare again, to pen the deeds of my valorous knight with his coarse and ill-trimmed ostrich feather. This is no weight for his shoulders, no task for his frozen intellect; and should you chance to make his acquaintance, you may tell him to leave Don Quixote's weary and mouldering bones to rest in the grave, nor seek, against all the canons of death, to carry him off to Old Castile, or to bring him out of the tomb, where he most certainly lies, stretched at full length and powerless to make a third journey, or to embark on any new expedition. For the two on which he rode out are enough to make a mockery of all the countless forays undertaken by all the countless knights errant, such has been the delight and approval they have won from all to whose notice they have come, both here and abroad. Thus you will comply with your Christian profession by offering good counsel to one who wishes you ill, and I shall be proud and satisfied to have been the first author to enjoy the pleasure of witnessing the full effect of his own writing. For my sole object has been to arouse men's contempt for all fabulous and absurd stories of knight errantry, whose credit this tale of my genuine Don Quixote has already shaken, and which will, without a doubt, soon tumble to the ground. Farewell.

Our greatest foes, and whom we must chiefly combat, are within.

Control your tongue, for from it flow the greatest evils of human life.
