Now with what flight you ought to flee men, sister Florentina, judge for yourself, if you will so carefully avoid the women of the world. Let any man, if he be holy, hold no familiarity with you; lest by the frequency of seeing one another the holiness of both be either defamed or destroyed. For she who has offered an occasion of perpetrating an evil deed will fall from the charity of God; and she who, though she does no evil, yet by report nourishes a most evil reputation, will fall from the charity of her neighbor. For a different sex placed together is titillated by the same instinct whereby it is born; and the natural flame is stirred, if anything aptly fitted touches it. Who has bound fire in his bosom and shall not be burned? Fire and tow, each contrary to the other, when brought together feed the flames.
