therefore now the concept of
existence on a higher plane where it comprises within itself stability
as well as change, being as well as development. Arrived at this point
we find that "species and genera in fact the special and the general,
are the simplest forms of differentiation, without which the
constitution of things cannot be grasped."

But this is a means of distinguishing quality and after a discussion
of this part of the subject we proceed "Over against the idea of
species stands the idea of the whole, a homogeneity, as it were, in
which no differentiation of species can longer be found," so we pass
from quality to quantity and this is always "capable of measurement."

Let us compare this "clear analysis of the actual, universal scheme of
things" and its "real, critical standpoint" with the fever-phantasies
of a Hegel. We find that Hegel's "Logic" begins with existence as does
that of Herr Duehring; that existence displays itself as nothing, as
with Herr Duehring; that out of this not-being, a leap is made into
being, and that existence is the result of this, that is a more
complete and higher form of being, as with Herr Duehring. Being leads
to quality, quality to quantity, just as with Herr Duehring. And in
order that no essential shall be lacking Herr Duehring tells us
elsewhere "from the realm of absence of sensation man leaps to that of
sensation in spite of all the quantitative steps with but one
qualitative leap ... from which we can show that he is entirely
differentiated from the mere gradation of one and the same quality."
This is just the Hegelian standard of measurement according to which
mere quantitative expansion or contraction causes a sudden qualitative
change at a given point, as for example with heated or cooled water,
there are points where the spring into a new set of conditions is
fulfilled under normal circumstances, and where therefore quantity
suddenly changes into quality.

Our investigation has likewise sought to penetrate to the deepest
roots, and discovers the rooted Duehring foundations to be the
"fever-phantasies" of a Hegel, the categories of the Hegelian logic,
in the first place, teachings in regard to existence after the antique
Hegelian method, and an ineffective cloak of plagiarism.

And not content with purloining the whole scheme of existence from his
despised predecessors, Herr Duehring after giving the above example of
a change of quantity into quality has the cool
