For a few years I have been fascinated by the attempt of certain thinkers to create an 'ars combinatoria' or combinatory art, the purpose of which is to combine all the disciplines of knowledge into one overarching system which would basically explain everything there is to know in the universe, while also giving the student the ability to see how all the sciences are ultimately interconnected. One may be tempted to pass this off as an erratic fancy if there wasn't such a formidable host of Catholic authors who have attempted this very project with great seriousness. The three that come to mind are Blessed Raymond Lull, a 14th century Franciscan; Pico della Mirandola, the great Italian humanist; and Athanasius Kircher, a polyglot and polymath 17th century Jesuit. All three shared a vision of a science above every other science...all three were also steadfast Catholics, with one even allowed a cult by Pius IX (?). But their works seem to have been picked up more by alchemists than Catholic thinkers. My question is this: is such a science even desirable? And if so, is it feasible? I'm also curious to know if anyone can think of anybody else, either ancient, medieval, or modern, who has tried to take on a similar project?
