وَمِنْهَا بَدِيهِيَّاتٌ وَقَدْ تَقَعُ فِيهَا اخْتِلَافَاتٌ
Among these are self-evident judgments in which disagreements may arise.
The skeptic objects that even claims presented as self-evident are disputed, sometimes requiring subtle arguments to resolve objections. How, then, can they be called immediate and certain?
Two preliminary questions are important. Are the disputants affirming and denying the very same proposition in the same respect? And is their disagreement about the basic judgment itself, or about the wording, an additional premise, or a derived implication?
Calling a proposition “self-evident” is an assertion about its status, not a demonstration that it possesses that status. The actual content and grounds of the claim must be examined.
