In each table the number twelve arises from, firstly, an initial division into two: the Mathematical and the Dynamical; a second division of each of these headings into a further two: Quantity and Quality, and Relation and Modality respectively; and, thirdly, each of these then divides into a further three subheadings as follows.
The branches of science, also referred to as sciences, scientific fields or scientific disciplines, are commonly divided into three major groups: .

They held that only monophyletic groups should be accepted as formal ranks in a classification and that – while this approach had been impractical previously (necessitating "literally dozens of eukaryotic 'kingdoms '") – it had now become possible to divide the eukaryotes into "just a few major groups that are probably all monophyletic".
