# Integers and Proportion

In Measure & Rule it was stated that Science, as part of its general empirical approach, presents quantitative information as if it were neutrally derived, on the basis of a hypothetical 1:1 relationship between the units of measurement and the object measured. This is the basis of scientific objectivity – the units of measurement are understood to be qualitatively neutral. The mechanical understanding of natural phenomena inevitably involves some attention to qualitative criteria, and to assessments and descriptions frequently involving the use of figurative language. This unavoidably entails a degree of subjective interpretation; however, we can resolve the uncertainty implicit in qualitative description so long as the units by which we measure natural phenomena remain proportionally invariant. Proportional invariance in quantitative assessment is guaranteed if numbers can be relied upon to function as indices of absolute value. Hence the importance of the concept of numbers as *integers*, where value appears as an intrinsic, self-contained ('integral') property – having no bearing or influence upon, and likewise being uninfluenced by, other adjacent or proximate values.

In the title page of this section, I have outlined a technical critique of this received definition of integers, based upon the *relative frequency* of individual digits with respect to the limited range of digits available within any particular numerical radix. Relative frequency is a property that must be determined *extrinsically*, i.e., *between* integers, based upon the group characteristics of the governing radix, where the principle of variance is that of the restrictive array of available digits through which values may be represented (0-9 in decimal, 0-7 in octal, for instance). For instance, a '1' (or a '0') in binary notation exhibits a higher relative frequency than its corresponding instance in decimal, or in any other radix, even though the corresponding values are quantitatively equal. Similar relative comparisons can of course be made between other available digits in any combination of radices. The case of binary is exemplary as it opens up the possibility of interpreting the either/or relationship of '1/0' in terms of the 'true/false', or 'positive/negative' distinction; hence, a distinction based upon *qualitative* criteria (in their simplest forms), rather than strictly quantitative ones. If this tendency towards qualitative potential is extrapolated *in principle* from the binary example, with respect to the variable relative frequency of digits when transposed across a diversity of radices, then we have an analytical basis for understanding the qualitative potential of 'integers' (if indeed we are content to continue with that designation, with its overtones of 'intrinsicness'), and a justification for rethinking their conventional interpretation as bearers of integral, or absolute, values.

Does the issue of relative frequency exhaust this critique? There may in addition be a meaningful epistemological critique of proportional invariance (or 'rational proportionality'), which considers the nature of integers primarily as symbolic constructs (rather than as phenomenal objects in their own right), and their rootedness in the requirement for the cognitive organisation of concrete categories of objects – suggesting thereby their association with customary expectations of *use* and *scale* with respect to those individual object categories. Hence, in terms of our everyday requirement for numbers to assist in the counting, possessing, and exchanging of objects in various categories, those numbers will always in practice bear some qualitative relationship to the categories of objects they organise and measure. The principle of rational proportionality eschews such qualitative dependencies, based as it is upon the idea of integers as abstract formal entities with self-contained values, whose objectivity transcends their application to any specific instance of quantity. Therefore, while an insistence upon absolute proportional invariance may satisfy the discourses of mathematics and the empirical sciences, and may also constitute a mercantile advantage to the extent that it gives vent to the smooth liquidity of exchange mechanisms, when applied to the measurement and quantification of tangible real-world objects, the abstract formality of the units of measurement is antithetical to the common purpose of maintaining adequate categorial distinctions, based upon customary expectations of use and scale.

There is a further aspect to the 'technical' critique referred to above, but which concerns the issue of an integer's relative *position*, rather than its frequency. The conventional definition asserts integers as stable entities of fixed intrinsic value, so that the movement between each integer and the next is a series of rational 'jumps' in value, each equal to the unit '1'. This permits individual expressions of value to be considered as discrete wholes, whose values are unaffected by adjacent or proximate values. If however we consider the simple reciting of numbers in sequence (or the sequential counting of a series of objects), this implies a cognitive process, rather than a purely mechanical one. Each progressive counting instance entails an awareness of the preceding value (by memory), and of the succeeding value (by projection); so that a counting instance of, say, '5', involves a mental *oscillation* between each of the adjacent values '4' and '6'. In this sense our instance of '5' loses its rational stability as a fixed index of value, and emerges as a *dispositional effect* of each of its adjacent values. In these terms it should not be discounted that it perhaps also makes an important difference, in terms of its dispositional properties, or its relative potential, whether a '5' is the maximal available integer (as in the case of *senary* – base-6), or whether it occupies a near median position, as in the case of decimal. Furthermore, and independently of any excercise of consecutive counting, we might also wish to consider the dispositional effects of *non-consecutive* adjacent values within any sequence of digits.

It ought to be clear that these features of numerical behaviour cannot be explained in terms of *unbounded* rational principles – only by acknowledging that rationality operates within formally circumscribed limits – the ratios that hold between the integers in a decimal notation, while internally consistent, cannot be assumed to be proportionally consistent with those between the same values expressed in any alternative radical notation, as the ratios between decimal values must be strictly determined by the rules governing their expression within decimal notation. We are accustomed, for most quantitative purposes, to working within the decimal rational schema; but we misconstrue the conditions of proportionality operating restrictively within the decimal schema if we assume that those conditions operate universally across diverse numerical radices; or, as a correlative to that assumption, that rational proportionality is somehow *given* in the very act of measuring.

This should not perhaps be too surprising to us when we consider that numbers are primarily tools of the human understanding, deriving originally from the need to quantify and manage objects having at least notional concrete existence, and which therefore entail qualitative dependencies. Numbers do not possess any phenomenal properties in their own right – they are derivations under the general *concept* of number, and are therefore bound by intuitive as well as rational processes. What makes the idea seem at first strange and esoteric is the legacy of nearly 400 years of modern scientific attempts to reduce Nature to a set of objective mechanical principles, and the requirement of an absolute system of measurement in order to achieve this. The twin imperatives of measurement and calculation predisposed Enlightenment Science and its descendents to caricature the qualitative determinants of numbers as superstitious, fanciful, and archaic.

## Precision Points, or Intervals?

We are accustomed to the practice of representing a sequence of consecutive integers as fixed points on a linear scale (such as in the numerical divisions that populate the axes in a graph showing a mathematical equation). Positions on the axes lying between fixed points would therefore indicate fractional values of integers – suggesting the integers here are serving merely as 'gatekeepers' for the (more unruly) rational and real numbers. This describes a typical *linear* distribution. However, the precise alignment of integers with discrete points on a linear scale emphasises the role of integers as abstract entities, and is incompatible with some of the ways in which we commonly represent the natural numbers (a major sub-set of the integers). For instance, to accommodate certain roles of the natural numbers in describing the (not strictly linear) apportionment of numeric value corresponding to familiar divisions in space and time, we would need to identify those numbers, not with precise fixed points on the scale but with the *whole interval lying between two fixed points*.

In identifying certain periods of time, or regions in space, we are accustomed to using whole numbers to represent entire periods or regions (the word 'zone' covers both uses). We may speak of 'week-1' to cover any point in time in a particular 7-day duration, for instance; or use a numeric description for concentric zones in space, such as in the London Underground map, where 'zone-2' describes any point between the lines of concentric division separating it from zones 1 & 3 (stations occurring precisely on the line are understood to occupy both adjacent zones simultaneously). In these examples the number applies to a whole interval in time or region in space, and there is no meaningful place for the idea of a fractional part of any integer. This suggests that integers may be variously employed in ways that are either *inclusive or exclusive* with respect to the rational and real numbers.

The observation that points lying exactly on the line dividing two adjacent zones occupy both zones simultaneously suggests a partial analogy with the description of sequential counting given above, where '5' was described as involving a mental oscillation between '4' and '6'. To explore this 'wave' analogy further – in physics, for instance, we might wish to consider a continuous sine wave in terms of its discrete single iterations, and thereby to identify them consecutively as iterations 1, 2, 3, etc., and so to dissociate the numeric notation from any particular point of amplitude of the sine wave. Such dissociation would be impossible for any precise positional point on the horizontal axis, so that in this exercise integers would also need to be associated with the entire parabolic interval of the sine wave. By exploring these kinds of 'periodic' or 'zonal' features in certain ways of using integers it may help to illuminate for us why it is that the received definition of the integers as discrete entities with transcendental properties is so clearly inadequate at explaining the varied roles and functions that integers perform for us.

## Logarithms – The Imperative of Calculation

Logarithms were first developed as late as the 17th century by John Napier (1614), and later by Leonard Euler.^{1} The inspiration for this development was the desire to make complex numerical calculations simpler and more manageable, i.e., by reducing *geometrical* math progressions (number series based upon multiplication or division) to *arithmetic* progressions (those based upon addition or subtraction). In the absence of electronic aids to calculation, this made it possible to systemise handwritten complex calculations (and especially, for instance, financial calculations of compound interest) by reference to logarithmic tables. So, where one needs to perform complex calculations involving large integers, large differences between values of *x* may be expressed as much smaller differences in terms of Log(*x*).

The function relies on the principle that numerical differences can be reduced or 'crunched' according to a set of essential ratios. The most useful of these ratios are *common logarithms* (log_{10}), *binary logarithms* (log_{2}), and *natural logarithms* (log_{e}) – *e* being the 'irrational' mathematical constant developed by Euler, defined as the *"asymptotic quadrature of the hyperbola"*, and which is approximately equal to 2.71828 (log_{e}*x* is the inverse of the exponential function: *e*^{x}). The logarithmic roots of diverse number bases (log_{b}) are understood to be perfectly derivable from 'common' (decimal) logarithms, according to the formula: log_{b}*x*=log_{10}*x*/log_{10}*b*.

The function of logarithms is perhaps best illustrated through the idea of *scaling invariance*, and the application of this principle to the observation of *self-similarity* in the repetition of natural forms in ascending or descending scales, i.e., as *fractals*. As a fractal replicates, or cascades, its entire global structure throughout the distribution of its parts, logarithms may be used to express the proportional identities relating successive magnifications of the fractal – for example, in the ratios of scale between the segmented chambers of the *Nautilus* shell. Nature may indeed exhibit such regularities of proportion across scale in the physical properties of natural forms organically and inorganically. However, such features are characteristics of the structural and developmental properties of natural *physical* forms, which may be observed empirically. On the other hand, the derivation of radical logarithmic values from common (decimal) logarithmic ones according to the above formula implies that the resulting radical ratios are perfectly consistent with those in decimal – an assumption of proportional invariance that does not result from any empirical observation, but rather from the exercise of a metaphysical tendency. That is to say, it is not so much a reflection of proportional invariance, but an *enforcement* of it. After all, integers, which represent the form and the method of that enforcement, are but the reified characters of modern abstract arithmetic notation, having as it were 'forgotten their roots' as symbolic constructs, formed out of the requirement to organise qualitative categories of objects with respect to intuitive criteria of use and scale. Hence, proportional invariance asserts qualitative indifference *a priori*, essentially in a manner that promotes all objects ruthlessly towards the system of their exchange.

## The Historical Context

Napier's development of the logarithmic principle was the result of his having spent most of the last twenty years of his life calculating:

*N* = 10^{7}(1−10^{-7})^{L}

for values of *N* between 5 and 10 million, in order to reveal *L* as a ratio, which he called the 'artificial number', and later 'logarithm' (literally meaning 'proportional number'). So, the logarithmic principle, and the later development of Euler's constant that it engendered, entailed from the beginning the (exclusive) employment of the *seventh* power of ten, and its inverse: 10^{-7} (Napier later went on to employ 10^{-5} also). Of course, within the decimal rational schema, each successive power of 10 *is* proportionally consistent with each other exponential of 10, and the logarithmic difference of each exponential step is equal to 1. However, according to the analysis that the ratios of proportion found within the decimal schema are unique to decimal, there is no guarantee that the ratios between the 7th power of ten and other powers of ten will be consistent with the ratios between their corresponding values when expressed in any alternative numerical radix – after all those ratios must be determined uniquely according to the restrictive character-set of the governing radix, and not according to some external arbitrary principle.

It should be noted that the historical development of Napier's method occurred at a time of revolutionary changes in terms of mathematical and of philosophical understanding. In seeking to enhance the mechanical understanding of Nature and the Universe, Enlightenment scientists sought an antidote to centuries of Classical (Aristotelian) philosophical thinking, in which certain knowledge of natural forms and processes depended essentially upon the exercise of the intuition. In Classical understanding, knowledge derived from sense data was incomplete without the addition of deductive reasoning involving intuitive, or universal, principles. Empirical science, from the 17th century onwards, sought to disgorge this dependency by establishing new paths to certainty based upon an atomistic approach to knowledge – the progressive measurement and tabulation of inexhaustible raw empirical data. This required a complete revision in methodology, involving a severing of the connection between knowledge and intuition. Reliable, mechanical knowledge of cause and effect in Nature should only now be acquired through the painstaking enumeration of every conceivable experimental instance of a known phenomenon, to arrive at certain knowledge of its principle causes by inductive elimination. Hence, the inductive methodology established by Francis Bacon sought to establish a *tabula rasa* for scientific knowledge through the method of observational parsimony, eschewing teleology and the acquired habits of syllogistic reasoning – in fact, an attempt to eschew any input from the mind save for its clinical ability to observe and record the data provided from direct sense impressions.^{2}

In this context, a theory which acknowledged an intuitive dimension to the understanding of numerical quantity would have been regarded as archaic or superstitious – as counter-revolutionary, and an unnecessary hangover from the dark ages. Such a theory would have detracted from the primary instrumental function of numbers in facilitating progressive measurement and quantification, and the establishment of empirical certainty over the mechanics of true causes and effects.

In view of this enthusiastic revisionism in the development of early modern science, we can understand the urgency, and the temptation, of the reductions to scalar identities through which logarithms seem to facilitate the rational understanding of Nature, and of numbers. However, we should understand this not only as a revelation of new knowledge previously inhibited by the habits of thought instilled in philosophical doctrine (Bacon's *"idols of the mind"*^{3}), but also as the forging, by force of will, of a new kind of *indifference*, through the subordination of qualitative relations and the dominance of quantitative ones. A consequence of this indifference is that it precipitates a radical shift – a fault line – between the 'human' and the 'scientific'; between the mechanical-physical and the philosophical-ethical-spiritual; between the rational and the intuitive; and which will henceforth render these as incompatible discourses.
