"It is important to understand that rationalism is not itself rational. Rationalism cannot be derived from the reason. It is an arbitrary dogma. And yet it is upon this dogma that the outlook of the post 17th-century Western world has based itself...That is precisely what the doctrine of rationalism consists of: the illogical and arrogant denial that anything exists outside the material world of the five senses. Has she any rational reason for denying what all tradition tells her to be true? She has not. She merely repeats: 'I have not seen it, so it does not exist.' That is why rationalism is inherently irrational: and, frankly, naughty. A world based on the rationalist denial of higher Reality is like a group of naughty children who have got together to deny what all the grown ups tell them because they have not seen it for themselves and cannot bear that anyone should know better than them."
