الأوليات هي قضايا يجزم العقل فيها بمجرد الالتفات والتصور، ولا يحتاج إلى واسطة
First principles are propositions on which the intellect makes a firm judgment simply by attending to and conceiving them, without requiring an intermediary proof.
Conception here means adequately understanding the subject, predicate, and their relation. Once the meanings are grasped, assent follows directly.
A claim is not a first principle merely because someone quickly or strongly believes it. The point is that the relation becomes evident through the concepts themselves, without a separate middle term.
