AUTOBIOGRAPHY-Chesterton

conviction that there is one key which can unlock all doors brings back to me
the first glimpse of the glorious gift of the senses; and the sensational
experience of sensation. And there starts up again before me, standing sharp
and clear in shape as of old, the figure of a man who crosses a bridge and
carries a key; as I saw him when I first looked into fairyland through the
window of my father’s peep-show. But I know that he who is called Pontifex,
the Builder of the Bridge, is called also Claviger, the Bearer of the Key; and
that such keys were given him to bind and loose when he was a poor fisher in
a far province, beside a small and almost secret sea.
