The Twelve Volumes

Thirteen years of a child's life, thirteen volumes of the Quintivium (K + twelve), grouped into five developmental stages. Every volume carries the same spiral argument about the body — read at the depth a child can read it at that age.

Overview · Five Stages

The Arc, at a Glance


K–2

Wonderfully Made

The body as gift and wonder.

3–5

Stewards of the Body

The body as something entrusted.

Human Dignity

The body as imago Dei, philosophically defended.

11–12

Bioethics & Vocation

Christian bioethics, vocation, and the body at the thresholds of life.

A Note from the Curator

Each book of the Quintivium is the same argument read at the right depth for a child at that age. A kindergartner learns that she is “wonderfully made,” that her heart beats while she sleeps, and that God made her good. A high-school senior learns how moral theology applies to end-of-life decisions, how Catholic bioethics frames fertility, and how her vocation fits her body. Same argument; different depth; thirteen books.

From the Book of Proverbs
“Train up a child in the way he should go, and when he is old he will not depart from it.”
Proverbs 22:6 · RSV-CE
From “The Child Is Father to the Man”

The child is father to the man. How can he be? The words are wild. Suck any sense from that who can:   ‘The child is father to the man.’ No; what the poet did write ran, ‘The man is father to the child.’

Gerard Manley Hopkins, SJ · 1883
