Successive or Resolative divisions.

Class has for its conjugate to classify: genus, to generalize, but in a different sense: species again to specify but in a sense different from both.

In relation to the names employed for the designation of the aggregates of different dimensions, which are regularly the results of the successive divisions performed in a system of logical subalternation, what is to be wished is - that in the instance of which intimation should be given, 1. in the first place of the number of nests or ranks of aggregates contained in the system, 2. of the rank occupied by the aggregate of which the word in question is the name.

In such a system the most capacious of all the aggregates, viz. that in which all the others are contained, will occupy the first rank; those which constitute the result of the first act of division to which it is subjected, the second rank; those which are the result of the division to which the results of the first division are subjected, the 3 d. rank.

The number of nests or ranks will be one more than the number of the acts of division, to which the aggregate, which occupies the most capacious, highest, and first rank, has been subjected.
