  point。 (b) The negation as negation; however; is itself spatial; and the relation of the point to space
  is the line; the first otherness of the point。 (c) The truth of the otherness is; however; the negation
  of the negation。 The line; therefore; passes over into the plane; which on the one hand is a
  determinacy opposed to line and point; and thus is plane in general; but on the other hand is the
  suspended negation of space; and thus the re…establishment of spatial totality; which; however;
  now contains the negative moment within itself an enclosing surface; which splits off an individual;
  whole space。
  That the line does not consist of points; nor the plane of lines; follows from their concepts; for the
  line is the point existing outside of itself relating itself to space; and suspending itself and the plane
  is just as much the suspended line existing outside of itself。…Here the point is represented as the
  first and positive entity; and taken as the starting point。 The converse; though; is also true: in as far
  as space is positive; the plane is the first negation and the line is the second; which; however; is in
  its truth the negation relating self to self the point。 The necessity of the transition is the same。…
  The other configurations of space considered by geometry are further qualitative limitations of a
  spatial abstraction; of the plane; or of a limited spatial whole。 Here there occur a few necessary
  moments; for example; that the triangle is the first rectilinear figure; that all other figures must; to be
  determined; be reduced to it or to the square; and so on。…The principle of these figures is the
  identity of the understanding; which determines the figurations as regular; and in this way grounds
  the relationships and sets them in place; which it now becomes the purpose of science to know。
  It may be noted in passing that it was an extraordinary notion of Kant's to claim that the definition
  of the straight line as the shortest distance between two points is a synthetic proposition; for my
  concept of straightness contains nothing of size; but only a quality。 In this sense every definition is a
  synthetic proposition。 What is defined; the straight line; is in the first place the intuition or
  representation; and the determination that it is the shortest distance between two points constitutes
  in the first place the concept (namely; as it appears in such definitions; cf。 § 110)。 That the
  concept is not already given by the intuition constitutes precisely the difference between the two;
  and is what calls for a definition。 That something seems to the representation to be a quality;
  though its specificity rests on a quantitative determination; is something very simple; and also the
  case for example with the right angle; the straight line; and so on。
  § 200。
  (2) Negativity; which as point relates itself to space and in space develops its determinations as
  line and plane; is; however; in the sphere of self…externality equally for itself and appearing
  indifferent to the motionless coexistence of space。 Negativity; thus posited for itself is time。
  § 201。
  Time; as the negative unity of being outside of itself; is just as thoroughly abstract; ideal being:
  being which; since it is; is not; and since it is not; is。
  Tune; like space; is a pure form of sensuousness; or intuition; but; as with space; the difference
  between objectivity and a contrastingly subjective consciousness does not matter to time。 If these
  determinations are applied to space and time; then space is abstract objectivity; whereas time is
  abstract subjectivity。 Time is the same principle as the I = I of pure self…consciousness; but the
  same principle or the simple concept still in its entire externality; intuited mere becoming; pure
  being in itself as sheer coming out of itself。 Time is just as continuous as space; for it is abstract
  negativity relating itself to itself and in this abstraction there is as yet no real difference。
  In time; it is said; everything arises and passes away; or rather; there appears precisely the
  abstraction of arising and falling away。 If abstractions are made from everything; namely; from the
  fullness of time just as much as from the fullness of space; then there remains both empty time and
  empty space left over; that is; there are then posited these abstractions of exteriority。…But time
  itself is this becoming; this existing abstraction; the Chronos who gives birth to everything and
  destroys his offspring。…That which is real; however; is just as identical to as distinct from time。
  Everything is transitory that is temporal; that is; exists only in time or; like the concept; is not in
  itself pure negativity。 To be sure; this negativity is in everything as its immanent; universal essence;
  but the temporal is not adequate to this essence; and therefore relates to this negativity in terms of
  its power。 Time itself is eternal; for it is neither just any time; nor the moment now; but time as time
  is its concept。 The concept; however; in its identity with itself I= 1; is in and for itself absolute
  negativity and freedom。 Time; is not; therefore; the power of the concept; nor is the concept in
  time and temporal; on the contrary; the concept is the power of time; which is only this negativity
  as externality。…The natural is therefore subordinate to time; insofar as it is finite; that which is true;
  by contrast; the idea; the spirit; is eternal。 Thus the concept of eternity must not be grasped as if it
  were suspended time; or in any case not in the sense that eternity would come after time; for this
  would turn eternity into the future; in other words into a moment of time。 And the concept of
  eternity must also not be understood in the sense of a negation of time; so that it would be merely
  an abstraction of time。 For time in its concept is; like the concept itself generally; eternal; and
  therefore also absolute presence。
  § 202。
  The dimensions of time; the present; future; and past; are only that which is becoming and its
  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 determ
