 Acknowledging the truth of a categorical statement meant verifying it, and this could only be done by taking that statement as the conclusion of a syllogism and then constructing the syllogism that would conclude it. There being three terms in a syllogism, two of which, the minor and the major, are present in the conclusion, the syllogism that leads to that conclusion can be constructed only if one figures out or guesses correctly what the middle term is that explains the connection between the two extreme terms. In other words, if we seek to verify the statement “A is C,” we must look for a suitable B to construct a syllogism of the form, “A is B, B is C, therefore A is C.” The significance of the middle term is discussed in the Posterior Analytics (I.34), where Aristotle further specifies, “Acumen is a talent for hitting upon (eustochia) the middle term in an imperceptible time” (Barnes 1994 transl.). Avicenna picked up on the very concept of the talent for hitting upon the middle term, literally translated in the Arabic version as ḥads (guessing correctly, hitting correctly upon the answer), and made it the cornerstone of his epistemology (Gutas 2001). This theory made the core of syllogistic verification by means of hitting upon the middle term the one indispensable element of all certain intellectual knowledge, and it explained why people differ in their ability to apply this syllogistic method by presupposing that they possess a varying talent for it, as with all human faculties.
