Assent can also be immediate: once the terms are properly understood, the truth of the relation is recognized without an extended chain of inference.
The text's examples are:
الكل أعظم من الجزء
The whole is greater than the part.
والاثنان نصف الأربعة
And two is half of four.
Once the concepts and suitable quantitative relation are grasped, the judgment becomes clear. The whole–part example concerns a quantitative whole and a proper part.
This is assent because a relation is affirmed, not merely because words have been repeated.
