| 2.5.2  | OTHER DERIVATIVE CATENAS | 
 From  a catena like the strongness or strength catena  we
 can  directly  derive  the strongness-moreness or 'strongerness'
 catena. But besides the derivations stronger or more
 strong, weaker or less strong and equally strong
 or equally weak we also know derivations like strengthening and
 weakening. There thus exists a strengthening catena as well.  In other
 systems we will find an honoring catena, betterment catena, heating catena,
 and so on. All these comparative catenas are increase catenas as
 explicit triads or differentiation catenas as quasi-duads.
 Differentiation  stands to  difference or otherness and different
 or other as strengthening  stands to  strongness and
 stronger, and as increase stands to moreness and more. 
 Also differentiation or increase catenas  can  be subdivided  into
 positivity differentiation and neutrality differentiation  catenas
 (or any other type dependent on the aspectual value taken).
 And, analogously to the case of difference catenas, the increase
 catena of an explicit triad is a positivity increase catena, and
 the increase catena of a bipolarity catena a neutrality increase
 catena.  These similarities  are  obvious.  They  hold for every
 increase or differentiation catena  and  the corresponding moreness
 or difference catena.
 Roughly speaking, the
 difference-catenary approach is primarily
 nontemporal,  whereas the differentiation-catenary approach is primarily
 temporal, at least on the assumption that every comparatively
 catenal thing exists over a period of
 time.
 Differentiation,  increase  or  decrease  can  be active or
 passive.
 For example, active positivity differentiation means
 making less or more positive(ly catenal) and passive
 positivity differentiation becoming or growing less
 or more positive(ly catenal).
 Active neutrality increase is making-more-neutral(ly catenal), and passive
 neutrality increase, becoming- or
 growing-more-neutral(ly catenal).
 (Literally speaking, one cannot make something positive or neutral,
 or become positive or neutral. A primary predicate just is or is not
 positive or neutral, while it is a nonpredicative primary thing which
 can or cannot be made or become positively or neutrally catenal.)
 Each differentiation catena is, as it were, the common denominator
 of two catenas: an active (transitive) and a passive (intransitive)
 one. Both catenas are each other's isorelative but --as already
 explained in 2.3.3-- the passive variant
 consists of pseudo-attributes only.
 The fact  that  a catena  is  a difference or differentiation
 catena, whether active or passive, says almost nothing about its
 position in the total derivation system, except that it is not a
 basic catena.  Only  if  the original catena  is basic is  the
 comparative catena a catena of the first level of derivation. In
 general, it is of the (n+1)-st level, if the original catena is
 of the n-th level. (Basic catenas  are  of  the  0-level  of
 derivation.)
 Catenas of the same basis are interchangeable. For example,
 the longitude, latitude and altitude catenas are interchangeable
 in that  the spatial co-ordinate which is regarded as longitude
 could also be latitude or altitude instead, and vice versa.
 Catenas derived from two interchangeable catenas in the same way
 are  interchangeable  themselves.  Interchangeable  catenas  are
 always equidimensional,  but equidimensional catenas need not be
 interchangeable.  The difference and differentiation catenas  of
 the longitude catena,  for instance,  are  equidimensional to it
 but  not  interchangeable  with  it  (with the exception of the
 monovariant positivity difference catena for which c=0, which is
 identical to it).  Monocatenal and bicatenal difference catenas
 are also equidimensional, but not interchangeable either: the
 length of an object,  for instance, or its shortness catenality,
 is  something else  than  the distance  between this object  and
 another object, or its closeness catenality.
 Unlike  difference  and differentiation  catenas,  which  are
 equidimensional to  the original  catena  from  which  they  are
 derived, differential catenas have their own dimension. 
 Consider, for example, velocity.
 If v represents an object's velocity, then v=∂s/∂t (with
 ∂s as the distance traveled and ∂t as the time spent); v is
 therefore s-differentiated-to-time, and its dimension is m/sec.
 On the basis of a terminological
 analogy  between  value collections and catena extensionalities,
 we may say  that one can derive the motion catena by differentiating
 the longitude catena, or a catena interchangeable with it,
 to time.
 Hence, we shall call the motion catena, the quasi-duad corresponding to
 velocity, "a time-differential catena".
 The term velocity  is also used in the more general sense of
 rate of occurrence or action.
 In that case it corresponds to any time-differential catena, not just the
 one in the derivation system of the longitude catena.
 The differential catenas  to time  of the longitude, latitude
 and altitude catenas  are  mutually interchangeable.  It  may be
 said  that  each  of  the three time-differential catenas  is  a
 motion catena; it may also be said  that the motion catena is
 the common denominator of these and similar catenas.
 This is not a fundamental issue.
 Starting from  a differential catena  which is derived from a
 basic catena,  we  can  in turn  derive  a difference  or  other
 comparative catena from it.  For example, in the physical system
 of the longitude catena, the slowness catena is a modulus catena
 of such a differential catena. The dimension of this modulus catena
 is  the same as  the one of the differential catena, namely
 m/sec.  But also  when  we now comparatively derive a new catena
 from the slowness catena, for example, the bivariant differentiation
 catena with extreme aspectual value, the dimension remains
 the same.  Thus the dimension of this retardation catena is also
 m/sec. On the other hand, deceleration (and also acceleration)
 has the dimension m/sec2 in physics.
 The catena to which this deceleration belongs, however, is not the
 differentiation catena of the slowness or speed catena, but the
 time-differential catena of the speed catena.
 Just as  a derivative and a first derivative are  the same in
 mathematics,  so  a differential catena is  the same as a first
 differential catena.
 (In the theory of catenas a derivative need not be a differential catena
 tho.)
 A second differential catena is, then, the differential catena of a
 differential catena  with respect to the same form of catenality or
 quantity.
 The deceleration catena is no such second differential catena:
 it is the first differential catena of the modulus catena of the
 first differential catena  of  the longitude catena  or a catena
 with which it is interchangeable.
 In traditional mathematics  the differentials ∂v or
 DELTAv and ∂t or DELTAt are evaluated
 positive, if the new v or t value is closer to the positive extreme than
 the old one. The aspectual value is on this account supX or
 +INFIN.  Now  this view is typically  that
 from  the  perspective  of  positivity moreness,  based  on  the
 positivity increases of v and t.  What underlies this conception
 is  positivity differentiation.  The  differential  catena  thus
 derived is a positivity-differential catena.
 It  is  not possible  to make  a mathematical differentiation
 universally comparative, because the aspectual value will always
 determine  the value  of the derivative function.  On  the other
 hand,  we are just as justified of looking at DELTAv and
 DELTAt from the perspective of neutrality moreness,  and  to
 evaluate DELTAv and DELTAt positive if the
 new v or t is closer to zero  than the old one, and negative if it is
 farther away from it. The catena thus derived is a
 neutrality-differential catena.
 If û1 is the catena value of the original
 catena, and
 f+(û1)
 the value of the positivity differential catena, the value of the
 neutrality-differential catena is
 û2 =
 f0(û1) =
 ( | f(û1) | ×
       û1 ×
     f+(û1))
 ÷
 ( | û1| ×
     f(û1))
 for û1¹0 and
 f(û1)¹0 .
 If û1 ¹ 0 and
 f(û1) = 0, then
 f0(û1) = 0
 regardless of the value of
 f+(û1).
 (This is because we choose a point on the curve which
 is  a point  on  the tangent  midway  between the lower  and the
 higher triangular points.) If û1 = 0  and
 either f(û1)¹0
 or
 f+(û1)¹0,
 then f is indefinite; and if û1 = 0
 and both f(û1)¹0
 and
 f+(û1)¹0,
 f0 is infinite (even if
 f+ is finite).
 If  A is the difference catena of B,  then B may be called "a
 sum catena of A". Similarly, if C is the differential catena of
 D, D may be called "an integral catena of C". For example, the
 quasi-monad of energy  can be conceived of as an integral catena
 of the physical force catena  with respect to the length catena.
 Differential and integral catenas  have to be distinguished from
 the related quotient and product catenas.  The product catena of
 the physical force catena  and  the length catena  would be  the
 physical moment catena, while the integral catena is an energy
 catena.  Nevertheless,  differential and quotient  catenas,  and
 also  integral and product  catenas,  have  the same  dimension,
 granted that the original catenas are the same.
 As the kinds of
 catenical derivations are closely related
 to the kinds of mathematical operation, it is worth our while to briefly
 consider the position of the simplest mathematical operations.
 The first pair  of operations  is,  then,  that  of
 addition (a + b = c) and substraction (a - b = c).  There is  no repetition
 involved in these operations.  In the theory of catenas  it
 is  the derivation  of  a comparative and equidimensional catena
 which  is  the analog  of  the mathematical sort of operation on
 this zero-level of reiteration.
 (All mathematical operations or functions may also be employed, however,
 to express logically contingent relationships between catena values,
 something that is not our concern here.)
 The prototypical mathematical operation on the first level
 of reiteration is multiplication (a × b = c). This is in the
 first instance nothing else than a form of reiterative adding-up:
 b × a = a + a + ... + a , or  
 b × a = SUM(i=1, b) ai
 (ai=a for every i).
 Its correlative is division (a ÷ b=c). The derivations of
 nonequidimensional differential and integral catenas, and of quotient
 and product catenas,  are  the catenical analogs of mathematical
 operations on this level.
 The prototypical mathematical operation on the second level
 of reiteration is  involution  or the raising of a quantity to
 power (ab = c or a××b = c).  This is in the first
 instance nothing else than a form of reiterative multiplication:
 a ×× b = a × a × ... × a , or
 a  × b =  PRODUCT(i=1,b) ai
 (ai=a for every i).
 The correlative of this second-level operation is evolution, the
 extraction  of a mathematical root ( b ROOT a=c ). In  their original shape
 the numbers were what mathematicians traditionally call "natural".
 It would be naive  to take it for granted now that the number
 of  sorts  of  mathematical operation  is  thus  exhausted.  For
 we can continue ad infinitum  by  repeating  the operation  on
 the previous level of reiteration. On the third level this would
 involve  reiterative involution with its related forms of operation.
 But on this and higher levels ordinary, and also mathematical,
 language  just lack  the terminology to express ourselves,
 even if we would  like to.  Nevertheless,  it is  possible to
 develop a universal notational system for reiterative operations
 of all levels by means of novel mathematical symbols. Suffice it
 here to recognize  that  there are not only other catenas on the
 first level of reiteration besides differential catenas but also
 catenas  on  higher operational levels of reiteration.
 They are catenas of
 primary predicates for which there is
 even no name in scientific or technical noncatenical discourse.
