  In John Buridan's masterpiece of the mid-fourteenth century,  the Summulae de Dialectica, we can find all three of the  conceptions outlined in   Section 1.1  above. He distinguishes explicitly between divisions, definitions and demonstrations, corresponding to decompositional, interpretive and  regressive analysis, respectively. Here, in particular, we have  anticipations of modern analytic philosophy as much as reworkings of  ancient philosophy. Unfortunately, however, these clearer forms of  analysis became overshadowed during the Renaissance, despite—or perhaps because of—the growing interest in the original Greek  sources. As far as understanding analytic methodologies was  concerned, the humanist repudiation of scholastic logic muddied the  waters.
