Quotethe whole fabric must be ill-shaped, declining, hanging over, leaning and irregular, so that some parts will seem ready to fall and tumble down, because the whole was at first disordered by false principles.
In accord with the frequent pattern of using repetition for emphasis, I think that last passage I quoted in the post above is probably a mirror of this passage, and this one too should be read as sweeping in effect, something like:
"So the whole structure of our life will necessarily be ill-shaped, declining, hanging over, leaning, and irregular, so that some parts will seem ready to fall and tumble down, if we erect the structure of our life in a disorderly manner based on a false understanding of the way our canonical faculties work."
