it is not surprising that someone who loves something ugly and then does not do so in anything else has happened nor in someone who has been naturally inclined to prefer something inferior but in someone who used to look with the eye of truth and then a passing passion overcame him after a long period of remaining in the wilderness and turned him away from what his soul had known a turning that became his nature and his first nature went away while he knew the superiority of what he had been upon at first so when he returns to himself he finds that it refuses anything but the inferior so he is amazed at this strong overcoming and great domination. he is more truthful in love truly than someone who is adorned with the characteristics of a people he is not from and claims an instinct that does not accept him so he claims that he chooses whom he loves. but if the lover occupied his insight and overthrew his thought and wronged his discrimination it would stand between him and choosing and seeking. and in that i say a poem from him 
وليس من العجب فيمن أحب قبيحا ثم لم يصحبه ذلك في سواه فقد وقع من ذلك، ولا في من طبع مذ كان على تفضيل الأدنى، ولكن في من كان ينظر بعين الحقيقة ثم غلب عليه هوى عارض بعد طول بقائه في الجمام فأحاله عما عهدته نفسه حوالة صارت له طبعا، وذهب طبعه الأول وهو يعرف فضل ما كان عليه أولا، فإذا رجع إلى نفسه وجدها تأبى إلا الأدنى، فأعجب لهذا التغلب الشديد والتسلط العظيم. وهو أصدق في المحبة حقا ممن يتحلى بشيم قوم ليس منهم، ويدعي غريزة لا تقبله ، فيزعم أنه يتخير من يحب. أما لو شغل المحب بصيرته، وأطاح فكرته، وأجحف بتمييزه، لحال بينه وبين التخير والارتياد. وفي ذلك أقول شعرا منه
