“The infidelity that springs from the heart is not to be reached by a course of lectures on the evidences of Christianity; argument did not cause, and argument will not remove it.”

A similar statement apparently derived from this version has become widely attributed to Herbert Spencer, but there are no records of Spencer ever saying or writing it, the first known attributions to him occurring in 1922 as the epigraph to Le Roy Campbell's The True Function of Relaxation in Piano Playing: A Treatise on the Psycho-Physical Aspect of Piano Playing, With Exercises for Acquiring Relaxation: https://books.google.com/books?id=gjMuAAAAYAAJ&printsec=frontcover&source=gbs_ge_summary_r&cad=0#v=onepage&q&f=false "There is a principle which is a bar against all information, which is proof against all argument and which cannot fail to keep a man in everlasting ignorance! That principle is condemnation before investigation".
Variant: There is a principle which is a bar against all information, which is proof against all argument, and which cannot fail to keep a man in everlasting ignorance. This principle is, contempt prior to examination.

Tlön, Uqbar, Orbis Tertius (1940)
Context: Hume noted for all time that Berkeley's arguments did not admit the slightest refutation nor did they cause the slightest conviction. This dictum is entirely correct in its application to the earth, but entirely false in Tlön. The nations of this planet are congenitally idealist. Their language and the derivations of their language — religion, letters, metaphysics — all presuppose idealism. The world for them is not a concourse of objects in space; it is a heterogeneous series of independent acts. It is successive and temporal, not spatial.

Ode interview (2009)
Context: A lot of the arguments about religion going on at the moment spring from a rather inept understanding of religious truth … Our notion changed during the early modern period when we became convinced that the only path to any kind of truth was reason. That works beautifully for science but doesn't work so well for the humanities. Religion is really an art form and a struggle to find value and meaning amid the ghastly tragedy of human life.

A Poets View (1984)
Context: Acknowledgement, and celebration, of mystery probably constitutes the most consistent theme of my poetry from its very beginnings. Because it is a matter of which I am conscious, it is possible, however imprecisely, to call it an intellectual position; but it is one which emphasizes the incapacity of reason alone (much though I delight in elegant logic) to comprehend experience, and considers Imagination the chief of human faculties. It must therefore be by the exercise of that faculty that one moves toward faith, and possibly by its failure that one rejects it as delusion. Poems present their testimony as circumstantial evidences, not as closing argument. Where Wallace Stevens says, "God and the imagination are one," I would say that the imagination, which synergizes intellect, emotion and instinct, is the perceptive organ through which it is possible, though not inevitable, to experience God.
