The Illumanati

I have two sets of the "Illuminati Trilogy" appropriately, by two different authors, describing 3 peoples quests, quite independently of one another, to find out "What's Really Going On", and who's in charge of it.

In one of these six books, is a quote that I've come to appreciate over the years, that runs along the lines of this:

There exists a hierarchy of jobs one can get that involve the talents of accurate observation and recording of facts to reach a conclusion. At the top of this list must be things like "research scientist", or if you have the talent, but not the advanced degree, try "police detective". If you have no talent for this sort of thing at all, but like that sort of work, there's always journalism.

Day after day I keep seeing the great truth of this, but I can't find the original source of the quote.

How about you?
