The scientific observer of the realm of nature is in a sense naturally and inevitably disinterested. At least, nothing in the natural scene can arouse his bias. Furthermore, he stands completely outside of the natural so that his mind, whatever his limitations, approximates pure mind. The observer of the realm of history cannot be disinterested in the same way, for two reasons: first, he must look at history from some locus in history; secondly, he is to a certain degree engaged in its ideological conflicts.
Reinhold NiebuhrA wise architect observed that you could break the laws of architec75tural art provided you had mastered them first. That would apply to religion as well as to art. Ignorance of the past does not guarantee freedom from its imperfections.
