“The unknown
Is life to love, religion, poetry.”

Translations, From the French

R. S. Thomas : Priest and Poet, BBC TV (2 April 1972)
Context: Any form of orthodoxy is just not part of a poet's province … A poet must be able to claim … freedom to follow the vision of poetry, the imaginative vision of poetry … And in any case, poetry is religion, religion is poetry. The message of the New Testament is poetry. Christ was a poet, the New Testament is metaphor, the Resurrection is a metaphor; and I feel perfectly within my rights in approaching my whole vocation as priest and preacher as one who is to present poetry; and when I preach poetry I am preaching Christianity, and when one discusses Christianity one is discussing poetry in its imaginative aspects. … My work as a poet has to deal with the presentation of imaginative truth.

Context: If what distinguishes the greatest poets is their powerful and profound application of ideas to life, which surely no good critic will deny, then to prefix to the word ideas here the term moral makes hardly any difference, because human life itself is in so preponderating a degree moral.
It is important, therefore, to hold fast to this: that poetry is at bottom a criticism of life; that the greatness of a poet lies in his powerful and beautiful application of ideas to life — to the question, How to live. Morals are often treated in a narrow and false fashion, they are bound up with systems of thought and belief which have had their day, they are fallen into the hands of pedants and professional dealers, they grow tiresome to some of us. We find attraction, at times, even in a poetry of revolt against them; in a poetry which might take for its motto Omar Khayam's words: "Let us make up in the tavern for the time which we have wasted in the mosque." Or we find attractions in a poetry indifferent to them, in a poetry where the contents may be what they will, but where the form is studied and exquisite. We delude ourselves in either case; and the best cure for our delusion is to let our minds rest upon that great and inexhaustible word life, until we learn to enter into its meaning. A poetry of revolt against moral ideas is a poetry of revolt against life; a poetry of indifference towards moral ideas is a poetry of indifference towards life.
