“Our own attitude to intercourse with "spirits" must be determined not by the authority of great teachers of the 13th or any other century, but by our examination in the light of the best secular knowledge of our time of the revelation of spiritual truth given by Christ.”

Context: Of late years the thoughts of men have been turned, by virtue of modern discoveries, as the result of countless influences, to an investigation of the foundation of orthodox religion. Other religions were put in the crucible of criticism, and nothing was found but dross. At last it occurred to the intelligent to examine our own religion, and this examination has excited great interest and great comment. People want to hear, and they want to hear because they have already about concluded themselves that the creeds are founded in error.

Introduction "On The Sources of Knowledge and of Ignorance" Section XVII, p. 30 Variant translation: I believe it is worthwhile trying to discover more about the world, even if this only teaches us how little we know. It might do us good to remember from time to time that, while differing widely in the various little bits we know, in our infinite ignorance we are all equal.
If we thus admit that there is no authority beyond the reach of criticism to be found within the whole province of our knowledge, however far we may have penetrated into the unknown, then we can retain, without risk of dogmatism, the idea that truth itself is beyond all human authority. Indeed, we are not only able to retain this idea, we must retain it. For without it there can be no objective standards of scientific inquiry, no criticism of our conjectured solutions, no groping for the unknown, and no quest for knowledge.
