Petrarch's brother Gherardo takes the steep direct ridge while Petrarch keeps searching for gentler routes that turn out to lead downward, forcing him to climb back and lose time repeatedly. The detour costs more effort than the hard route would have, because avoiding difficulty only postpones it and adds distance.
Petrarch reads his stumbling ascent as an exact figure for the soul's journey toward the blessed life: the goal is high, the path narrow, and the desire is real, but the will keeps sliding toward the low, comfortable ways. Treating a bodily ordeal as an allegory lets concrete fatigue and wrong turns become evidence about inner habits.
At the top, Petrarch opens the Confessions at random and lands on the line rebuking people who marvel at mountains, seas, and stars but neglect themselves. He falls silent and turns his attention from the panorama to his own soul, so the moment of greatest outward view becomes the moment of inward turning.
Nothing is admirable except the mind, compared to whose greatness nothing else is great, and so marveling at external nature while ignoring oneself inverts the true order of attention. The height worth reaching is an inner elevation over base desires, not a physical summit.
Petrarch confesses that he now loves what he once loved, but less, and more against his will, and with some shame. Moral change is a gradual, contested transition in which old attachments persist alongside new ones, and honest self-accounting means tracking that partial, reluctant shift rather than claiming a clean conversion.
On the mountain Petrarch measures time: it is the tenth year since he left his studies in Bologna, and he reviews how his character has shifted across that span and projects forward another decade. Marking a fixed interval and auditing one's inner changes across it turns vague self-reflection into a concrete ledger of progress and backsliding.
