The Poll-Parrot stage is the one in which learning by heart is easy and, on the whole, pleasurable; whereas reasoning is difficult and, on the whole, little relished. At this age, one readily memorizes the shapes and appearances of things; one likes to recite the number-plates of cars; one rejoices in the chanting of rhymes and the rumble and thunder of unintelligible polysyllables; one enjoys the mere accumulation of things.

The Pert age, which follows upon this (and, naturally, overlaps it to some extent), is characterized by contradicting, answering back, liking to “catch people out” (especially one’s elders); and by the propounding of conundrums. Its nuisance-value is extremely high. It usually sets in about the Fourth Form.

The Poetic age is popularly known as the “difficult” age. It is self-centered; it yearns to express itself; it rather specializes in being misunderstood; it is restless and tries to achieve independence; and, with good luck and good guidance, it should show the beginnings of creativeness; a reaching out towards a synthesis of what it already knows, and a deliberate eagerness to know and do some one thing in preference to all others. Now it seems to me that the layout of the Trivium adapts itself with a singular appropriateness to these three ages: Grammar to the Poll-Parrot, Dialectic to the Pert, and Rhetoric to the Poetic age…

It is difficult to say at what age, precisely, we should pass from the first to the second part of the Trivium. Generally speaking, the answer is: so soon as the pupil shows himself disposed to pertness and interminable argument. For as, in the first part, the master faculties are Observation and Memory, so, in the second, the master faculty is the Discursive Reason. In the first, the exercise to which the rest of the material was, as it were, keyed, was the Latin grammar; in the second, the key- exercise will be Formal Logic. It is here that our curriculum shows its first sharp divergence from modern standards.
