 his affirmation of the origin of the body is inherent in him and his neglect of its form and name is like his neglect of the place of smell which are two appendages in the front of the brain similar to the nipples of the breast. for every human being knows that he perceives smell with his body but the place of perception is not formed for him and is not specified even though he perceives that it is closer to the head than to the heel and from the head itself to the inside of the nose is closer than to the inside of the ear. likewise a human being feels himself and knows that his identity by which he is sustained is closer to his heart and chest than to his leg so he estimates himself to remain without the leg but is not able to estimate himself to remain without the heart. so what they mentioned that he sometimes neglects the body and sometimes does not neglect it is not like that.
فإثباته لأصل الجسم ملازم له وغفلته عن شكله واسمه كغفلته عن محل الشم وإنهما زائدتان في مقدم الدماغ شبيهتين بحلمتي الثدي، فإن كل إنسان يعلم أنه يدرك الرائحة بجسمه ولكن محل الإدراك لا يتشكل له ولا يتعين وإن كان يدرك أنه إلى الرأس أقرب منه إلى العقب ومن جملة الرأس إلى داخل الأنف أقرب منه إلى داخل الأذن. فكذلك يشعر الإنسان بنفسه ويعلم أن هويته التي بها قوامه إلى قلبه وصدره أقرب منه إلى رجله فإنه يقدر نفسه باقيا مع عدم الرجل ولا يقدر على تقدير نفسه باقيا مع عدم القلب، فما ذكروه من أنه يغفل عن الجسم تارة وتارة لا يغفل عنه ليس كذلك.
