dissolution into the differences of being as the transition into nothingness; and of Nothingness as
the transition into being。 The immediate disappearance of these differences into individuality is the
present as now; which is itself only this disappearance of being into nothingness; and of
nothingness into being。
(1) The finite present is differentiated from the infinite in that the finite is the moment now and
hence as its abstract moments; as past and future; which is different from the infinite as from the
concrete unity。 Eternity as concept; h r; contains these moments in itself and its concrete unity is
therefore not the moment now; because it is motionless identity; concrete being as universal; and
not that which is disappearing into nothingness; as becoming。…Furthermore in nature; where time is
now; there does not occur the subsisting difference of these dimensions; they are necessarily only
in subjective representation; in memory; fear; or hope。 The abstract past; however; and future of
time is space; as the suspended space is at first the point and time。
(2) There is no science of time in opposition to the finite science of space; geometry; because the
differences of time do not have the indifference of being outside of itself which constitutes the
immediate determinacy of space; and therefore they can not be expressed as spatial
configurations。 The principle of time only reaches this ability when the understanding has paralysed
it and reduced its negativity to the unit。 This motionless unit; as the sheer carnality of thought; can
be used to form external combinations; and these; the numbers of arithmetic; can themselves be
brought under the categories of the truth as intuition or as understanding merely for itself because
the latter is only abstract; whereas the former is concrete。 This dead unit; now the highest
externality of thought; can be used to form external combinations; and these combinations; the
figures of arithmetic; can in turn be organised by the determination of the understanding in terms of
equality and inequality; identity and difference。 The science which has unity as its principle is
therefore constituted in opposition to geometry。
(3) The name of mathematics has moreover been used for the philosophical observation of space
and time; because it lies close to this observation; despite the fact that mathematics; as noted;
considers strictly the determinations of magnitude of its objects and not time itself but only the unit
in its configurations and connections。 To be sure; time becomes in the theory of movement an
object of science; but applied mathematics is generally not an immanent science; precisely because
it involves the application of pure mathematics to a given material and its determinations as derived
from experience。
(4) One could still; however; conceive the thought of a philosophical mathematics; namely; as a
science which would recognise those concepts which constitute what the conventional
mathematical science of the understanding derives from its presupposed determinations; and
according to the method of the understanding; without concepts。 However; since mathematics is
the science of the finite determinations of magnitude; which remain fixed in their finitude and valid;
and should not change in transit; thus it is essentially a science of the understanding。 And since it
has the ability to express spatial figures and numbers; which gives it an advantage over other
sciences of this kind; it ought to retain this ability for itself and to avoid contamination by either
concepts; like time; which are heterogeneous to it; or empirical purposes。 It therefore remains
open for the concept to establish a more fundamental consciousness than has hitherto been shown;
both in terms of the leading principles of the understanding and in terms of order and its necessity
in arithmetical operations; as well as in the theses of geometry。…If one wanted to treat the forms of
space and the unit philosophically; they would lose on these grounds their particular significance; a
philosophy of them would become a matter of logic; or would even assume the character of
another concrete philosophical science; according to the ways one imparted a more concrete
significance to the concepts。…
It would; however; be a superfluous and thankless task to try to use such an unmanageable and
inadequate medium as spatial figures and numbers for the expression of thoughts; and to treat them
violently for this purpose。 For the specific concept would always be related only externally to
them。 The simple elementary figures and numbers can in any case be used as symbols; which;
however; are a subordinate and poor expression for thoughts。 The first attempts of pure thought
took recourse to such aids: the Pythagorean system of numbers is the famous example of this。 But
with richer concepts these means became completely unsatisfactory; since their external
juxtaposition and contingent combination are not at all appropriate to the nature of the concept;
and make it altogether ambiguous which of the many possible relationships in complex numbers
and figures should be adhered to。 Besides; the fluid character of the concept is dissipated in such
an external medium; in which each determination falls into the indifferent being outside the others。
This ambiguity could only be removed by an explanation。 The essential expression of the thought is
in that case this explanation; and this symbolising is an empty superfluity。
Other mathematical determinations; such as infinity and its relationships; the infinitesimal; factors;
powers; and so ' on; have their true concepts in philosophy itself。 It is awkward to want to take
and derive these from mathematics; where they are employed in a nonconceptual; often
meaningless way; rather; they must await their justification and significance from philosophy。 The
truly philosophical science of mathematics as theory of magnitude would be the science of
measures; but this already presupposes the real particularity of things; which is only at hand in
concrete nature。
§ 203。
(5) Space and time constitute the idea in and for itself; with space the real or immediately
objective side and time the purely subjective side。 Space is in itself the contradiction of indifferent
being outside of others and undifferentiated continuity; and thereby the pure negativity of itself and
the transition into time。 Space converts into the individuality of the place。 Time is; equally; since its
moments held together in unity suspend themselves immediately; the immediate convergence into
indifference; into undifferentiated being apart from one another; or into space; so that its place is
precisely in that way immediate as sheer indifferent spatiality。 This disappearance and regeneration
of space in time and of time in space is motion;…a becoming; which; however; is itself just as much
immediately the identically existing unity of both; or matter。
The transition from ideality to reality; from abstraction to concrete existence; in this case from
space and time to reality; which appears as matter; is incomprehensible to the understanding; and
always converts therefore externally for the understanding; and as a given entity。 The usual
conception is to take space and time as empty and to be filled with matter from the outside。 In this
way material things are; on the one hand; to be taken as indifferent to space and time; and on the
other hand to be taken at the same time as essentially spatial and temporal。
What is usually said of matter is: (a) that it is composite; this refers to its identity with space。
Insofar as abstractions are made from time and from all form generally; it is asserted that matter is
eternal and immutable。 In fact; this follows immediately; but such a matter is also only an untrue
abstraction。 (b) It is said that matter is impenetrable and offers resistance; is tangible; visible; and
so on。 These predicates mean nothing else than that matter exists; partly for specific forms of
perception; in general for an other; but partly just as much for itself Both of these are
