This is supported by the work of French scholar M Fumaroli (see ref somewhere below in the entry). In addition what I wrote helps explain the link between prayer and oration in the Jesuit frame of mind, and also shows that the Ratio was used for a long time indeed ( I myself was partly taught by it!). Hope you will not mass destruct the paragraph (and by the way I also have one, even two, PhDs and am a rationalist).
