Barfield believed that the imagination plays a very important part in how we know. He rejected the model that science is the only way to truth, to acquiring truth. He felt that the imagination was laid behind even the work of science. It gave meaning to propositions. And so he felt that Lewis was missing out in his whole approach to reality on what made knowledge possible.
I was suddenly compelled to read the Hippolytus of Euripides.
“Oh God, bring me to the sea’s end
To the Hesperides, sisters of evening,
Who sing alone in their islands
Where the golden apples grow,
And the Lord of Oceans guards the way
From all who would sail
Into their night-blue harbors —
Let me escape to the rim of the world
Where the tremendous firmament meets
The earth, and Atlas holds the universe
In his palms.
For there, in the palace of Zeus,
Wells of ambrosia pour through the chambers,
While the sacred earth lavishes life
And Time adds his years
Only to heaven’s happiness”
… I was off once more into the land of longing, my heart at once broken and exalted as it had never been since the old days. I was overwhelmed. I called it Joy.
