[Edmund Burke] fought, as you know, against the ideas of the French Revolution, and his most effective weapon was his analysis of that irrational power which we call 'tradition'. I mention Burke because I think he has never been properly answered by rationalists. Instead rationalists tended to ignore his criticism and to persevere in their anti-traditionalists attitude without taking up the challenge. Undoubtedly there is a traditional hostility between rationalism and traditionalism. Rationalists are inclined to adopt the attitude: 'I am not interested in tradition. I want to judge everything on its merits and demerits, and I want to do this quite independently of any tradition. I want to judge it with my own brain, and not with the brains of other people who lived long ago.'I see confusion here. The right attitude is to judge ideas on their merits and demerits, but to do so with the aid of both reason and traditional knowledge. This is perhaps clearer to see if one renames "traditional knowledge" to "existing knowledge". Existing knowledge is good, and shouldn't be disregarded even by people with a very high opinion of reason and individual judgment.
That the matter is not quite so simple as this attitude assumes emerges from the fact that the rationalist who says such things is himself very much bound by a rationalist tradition which traditionally says them. This shows the weakness of certain traditional attitudes towawrds the problem of tradition.
Existing knowledge should be used whenever doing so seems unproblematic, and improved when it seems problematic. It should be respected as something valuable, but not something beyond criticism. I think this attitude harnesses the good points of both the rationalists and traditionalists and also demonstrates they are not fundamentally in conflict.
