ב. “Now since these three represent three different genera, the subjects and the two-fold opposite, there must be a higher genus over each of them which takes the first place, since the genus comes before its subordinate kinds. If the universal is taken away, so is the kind; on the other hand, if the kind, not the genus, for the former depends on the latter, but not the contrary way.” (_αα_) “The Pythagoreans have declared the one to be the highest genus of what is considered as in and for itself” (of subjects in their diversity); this is, properly speaking, nothing more than translating the determinations of the Notion into numbers. (_ββ_) “What is in opposition has, they say, as its genus the like and the unlike; rest is the like, for it is capable of nothing more and nothing less; but movement is the unlike. Thus what is according to nature is like itself; it is a point which is not capable of being intensified (_ἀνεπίτατος_); what is opposed to it is unlike. Health is like, sickness is unlike. (_γγ_) The genus of that which is in an indifferent relationship is excess and want, the more and the less;” in this we have the quantitative relation just as we formerly had the qualitative. ג. We now come for the first time to the two opposites: “These three genera of what is for itself, in opposition and in relationship, must now come under”—yet simpler, higher—“genera,” _i.e._ thought-determinations. “Similarity reduces itself to the determination of unity.” The genus of the subjects is the very being on its own account. “Dissimilarity, however, consists of excess and want, but both of these come under undetermined duality;” they are the undetermined opposition, opposition generally. “Thus from all these relationships the first unity and the undetermined duality proceed;” the Pythagoreans said that such are found to be the universal modes of things. “From these, there first comes the ‘one’ of numbers and the ‘two’ of numbers; from the first unity, the one; from the unity and the undetermined duality the two; for twice the one is two. The other numbers take their origin in a similar way, for the unity over moves forward, and the undetermined duality generates the two.” This transition of qualitative into quantitative opposition is not clear. “Hence underlying these principles, unity is the active principle” or form, “but the two is the passive matter; and just as they make numbers arise from them, so do they make the system of the world and that which is contained in it.” The nature of these determinations is to be found in transition and in movement. The deeper significance of this reflection rests in the connection of universal thought-determinations with arithmetic numbers—in subordinating these and making the universal genus first.
