وَاعْلَمْ أَنَّ الاسْتِثْنائِيَّ مُؤَلَّفٌ مِنْ مُقَدِّمَتَيْنِ: إِحْداهُما شَرْطِيَّةٌ وَتُسَمَّى كُبْرَى، وَالأُخْرَى اسْتِثْنائِيَّةٌ وَتُسَمَّى صُغْرَى، وَلِذٰلِكَ يُسَمَّى بِاسْمَيْنِ … فَالأَوَّلُ هُوَ الاسْتِثْنائِيُّ لِاشْتِمالِهِ عَلَى الاسْتِثْنائِيَّةِ، وَالثّانِي هُوَ الشَّرْطِيُّ لِاشْتِمالِهِ عَلَى الشَّرْطِيَّةِ.
Know that the exceptive syllogism is composed of two premises: one conditional, called the major, and the other exceptive, called the minor. That is why it has two names … The first, “exceptive”, because it contains the exceptive premise; the second, “conditional”, because it contains the conditional.

فَإِذا قُلْتَ مَثَلًا: إِمّا أَنْ يَكُونَ هٰذا الجِسْمُ أَبْيَضَ وَإِمّا أَنْ يَكُونَ أَسْوَدَ، لٰكِنَّهُ أَبْيَضُ، أَنْتَجَ أَنَّهُ لَيْسَ بِأَسْوَدَ … وَقَوْلُهُ دُونَ عَكْسٍ، أَيْ لِأَنَّهُ لا يَمْتَنِعُ ارْتِفاعُهُما، فَلا يُنْتِجُ رَفْعُ أَحَدِهِما وَضْعَ الآخَرِ، فَلَوْ قُلْتَ فِي المِثالِ المَذْكُورِ: لٰكِنَّهُ لَيْسَ بِأَبْيَضَ، لَمْ يُنْتِجْ أَنَّهُ أَسْوَدُ.
If you say, for instance, “This body is either white or black; but it is white”, it follows that it is not black … His words “not the reverse”: because both may be absent, denying one does not yield affirming the other; if in that example you said “but it is not white”, it would not follow that it is black.

درس
The Sullam treats the : a with a second premise that affirms or denies one of its sides, introduced by “but” (lākin). Al-Bājūrī explains its two names. It has two premises, a conditional one, called the , and an exceptive one, called the ; it is called exceptive after the second and conditional after the first.
With a (“if it is a human, it is an animal”), affirming the yields the and denying the consequent yields the denial of the antecedent. With a real disjunction (“the number is even or odd”), affirming either side yields the denial of the other and denying either yields the other.
With a disjunction that only bars joining, al-Bājūrī's example: “this body is either white or black; but it is white” yields “it is not black”. But not the reverse: since a body may be neither, “but it is not white” does not yield “it is black”.

پرسش 1
Why does the exceptive syllogism have two names, according to al-Bājūrī?
“The first, exceptive, because it contains the exceptive premise; the second, conditional, because it contains the conditional.”
پرسش 2
“This body is either white or black; but it is not white.” What follows?
The disjunction only bars joining; since both may be absent, denying one does not yield the other.
