Quote examples
Saint-John Perse
French Diplomat
In truth, every creation of the mind is first of all 'poetic' in the proper sense of the word; and inasmuch as there exists an equivalence between the modes of sensibility and intellect, it is the same function that is exercised initially in the enterprises of the poet and the scientist.
