But Bonaventure himself will tell us best the proper dispositions for reading him with profit. At the beginning of his Incendium amoris, wherein he teaches the three ways, purgative, illuminative, and unitive, which lead to true wisdom, he says: "I offer this book not to philosophers, not to the worldly-wise, not to great theologians perplexed with endless questions, but to the simple and ignorant who strive rather to love God than to know much. It is not by disputing, but by activity, that we learn to love. As to these men full of questions, superior in every science, but inferior in the love of Christ, I consider them incapable of understanding the contents of this book; unless putting away all vain show of learning, they strive, by humble self-renunciation, prayer, and meditation, to kindle within them the divine spark, which, inflaming their hearts and dispelling all darkness, will lead them beyond the concerns of time even to the throne of peace. Indeed by the very fact of their knowing more, they are better disposed to love, or at least they would be, if they truly despised themselves and could rejoice to be despised by others (Incend. amoris Prologus)."
