 after we shall begin by looking up the opposites involved in it, and which are to be united. Again, all our syntheses are to be involved in the highest synthesis, just shown up, and to be developed out of it. Hence, it will be our task to look up in the Ego and Non-Ego, which that synthesis unites, some opposite characteristics, which have not been united; and to unite these opposites through a new ground of relation, which, again, must be involved in the highest ground of relation; next, it will be our task to look up new opposites in the opposites united by this second synthesis, and to unite them in a third synthesis; and to continue this course until we arrive at opposites which can no longer be perfectly united, whereby we shall then be forced to enter the practical part of our science.

As antithesis is not possible without synthesis, and vice versa, so neither is possible without a thesis; that is, without an absolute positing, whereby a certain A (the Ego) is posited, not as the equal of any other, nor as the opposite of any other, but is absolutely posited. This, when applied to our system, gives it completeness and surety. It must be a system and one system; the opposites must be united so long as opposites still exist, and until the absolute unity is produced; which absolute unity, as will be shown hereafter, can, however, only be produced by a completed approach to the infinite, that is to say, never in time.

The necessity to opposit and unite in the above determined manner, rests immediately on our third
