CHAPTER XIII.

THE PHILOSOPHY OF NATURE AND IDEALISM.

What is meant by a 'philosophy of Nature'? 'To philosophise on Nature,'

says Schelling, 'means to lift it up out of the dead mechanism in

which it appears immersed,--to inspire it, so to speak, with liberty,

and to set it in free process of evolution: it means, in other words,

to tear ourselves away from the vulgar view which sees in Nature only

occurrences, or at the best sees the action _as a fact, not the action

itself_ in the action[1].' There is in short a process in nature

parallel in character to what Fichte had exhibited for consciousness.

The natural world is no longer subordinated, but to appearance

co-ordinate: and evolution or development, exhibited under the logical

title of a 'deduction,' is the common law of both. The real order and

the ideal order of the world are equally the work of an infinite and

unconditioned activity, 'which never quite exhausts itself in any

finite product, and of which everything individual is only as it were a

particular expression.' The nature which we see broken up in groups and

masses, and individual objects, is to be explained as a series of steps

in a process of development: the steps in a single continuous product

which has been arrested at several stages,--which presents distinct

epochs, but nevertheless all approximations, with divergences, to a

single original ideal.

In Nature, as in Mind, the most typical phenomenon is an original

heterogeneity, duplicity, or difference, which, however, points

back to a still more fundamental homogeneity, unity, or identity.

This primary unity or ground of unification does not indeed appear

to sight; the 'soul of Nature,' the _anima mundi,_ nowhere presents

itself as such in its undivided simplicity; but only as the perpetually

recurring re-union of what has been divided. But though unapparent,

the absolute identity is the necessary presupposition of all life

and existence, as of all knowledge and action. It is the link or

'copula' which perpetually reduces the antithesis to unity, and the

heterogeneity to homogeneity, and the different to redintegration. To

this fact of antithesis, presupposing and continually reverting to an

original unity, Schelling gives the name 'Polarity,' 'It is impossible

to construe the main physical phenomena without such a conflict of

opposite principles. But this conflict only exists at the instant

of the phenomenon itself. Each natural force _awakes_ its opposite.

But that force has no independent existence: it only exists in this

contest, and it is only this contest which gives it for the moment a

separate existence. As soon as this contest ceases, the force vanishes,

by retreating into the sphere of homogeneous forces[2].' Polarity,

therefore, is a general law of the cosmos.

A ceaseless, limitless activity, therefore, as the basis or groundwork

of all, for ever crossing, arresting, and limiting itself: an eternal

war, which, however, is always being led back to peace,--a process

of differentiation which rests upon, is the product of, and is for

ever forced back to integration, is the perpetual rhythm of the

natural universe. It is a process in which can be traced three grades,

stages, or 'powers' (first, second, and third, &c.). By its more

generally descriptive name it is called Organisation. 'Organism,'

says Schelling, 'is the principle of things. It is not a property

of single natural objects; but, on the contrary, single natural

objects are so many limitations, or single modes of apprehending the

universal organism[3].' 'The world is an organisation; and a universal

organism itself is the condition (and to that extent the positive)

of mechanism[4].' 'Mechanism is to be explained from organism: not

organism from mechanism.' 'The _essential_ of all things is _life_: the

_accidental_ is only the _kind_ of their life: and even the dead in

Nature is not utterly dead,--it is only extinct life.'

But if the conception of an organism be thus the adequate or

complete idea of Nature as a whole, that idea is only realised as

a third 'power' supervening on, and by means of two subordinate or

inferior ranges or 'powers.' The first stage is that occupied by the

mathematical and mechanical conception of the world,--the bare skeleton

or framework which has to be clothed upon and informed with life and

growth. This first 'power' in the world-process of antithetical forces,

under the control of, and on the basis supplied by, the original

thetic unity which synthetises them, is Matter. In Matter we have the

equilibrium and statical indifference of two opposing forces--one

centrifugal, accelerating, repulsive, the other contripetal, retarding,

attractive--which, working under the synthetising unity supplied by the

force of universal gravitation, build up in their momentary arrests

or epochs the various material forms. In this first 'power' we have

as it were the scheme or machinery through which organisation will

work: the outward and 'abstract, organism. And the essential feature

of this 'construction' or 'deduction' of matter is that it does not

take material atoms and build them into a world, but 'deduces' the

properties of matter as issuing from the play of opposing forces, and

as due to the temporary syntheses resulting from the presence of unity

making itself felt in the opposites.

A second and higher 'power' is seen in the physical universe as it

presents, itself to the sciences of electricity, magnetism, and

chemistry. If the former briefly be denominated the mechanical,

this is the chemical world. The law of polarity is here especially

prominent: the neutrality or indifference of parts is replaced by an

intenser antithesis and affinity: and the return from heterogeneity

to homogeneity takes place with more striking and even sudden effect.

Here, matter, even as inorganised, has a certain _simulacrum_ of life

and sensibility: there is in it the trace of a spirit which emerges

above the mere contiguity and juxtaposition of mechanical atoms. The

atomic theory shows itself less and less adequate as an attempt to

represent the whole phenomena of inanimate matter, and the material

universe is already charged with sympathies and antipathies which are

full of the promise and the potency of the organic world.

The mechanical theory of the universe, in the ordinary sense, which

deals with the mathematical formulation of the laws of planetary

movement, had been the work of the seventeenth century. The eighteenth

century had seen attempts to explain the _status quo_ of the

planetary system as a resultant from the evolution of an elementary

molecular state of the cosmic mass. With the close of the eighteenth

century there appeared a group of new sciences dealing with subtler

energies of matter,--with electricity, galvanism, and above all with

the connexions of chemical, electric, and magnetic science. The

ideas thus suggested--embraced with some generality under the title

Polarity--threw light backward upon the old mechanical conceptions,

and gave them a decidedly dynamic character. Even the tranquil rest

of geometrical figures came to be explained as a meeting point and

transition moment of opposite forces. But these ideas produced an even

greater effect on biology. Here, too, the need of a special 'vital

force' to explain life and organisation disappeared: organism was

but a higher stage, a completer truth of mechanism: and both found

their explanation in the antithesis and synthesis of forces, or in

differentiation and integration of what has recently been termed an

'idée-force.' In this direction, so far as Schelling was concerned,

the obvious stimulus came from the programme sketched by Kielmeyer at

Stuttgart in 1793, in a lecture 'on the proportions of organic forces,'

According to Kielmeyer there are three types of force in the animal

organisation, sensibility, irritability and reproduction[5]. The last

of these is the basic force which builds up and propagates the animal

system. With irritability, or contraction in response to external

stimuli--material adaptation to environment--a higher level of animal

life is reached. But the highest of all forces in the living being is

sensibility. In this same order may we reasonably conceive that the

'plan of nature' proceeds. Her first products show little beyond that

reproductive power which makes broad and high the pyramid of life. But

as the creature acquires increasing heterogeneity and a comparatively

independent position, it plays the part of a re-agent against stimuli,

and a source of movements. Lastly, it not merely responds to, but

assimilates and appropriates the impression into a sensation: it

internalises the external, and carries within itself by means of the

sensibility an ever-increasing picture of the world around it.

The idea of Evolution or Development, thus introduced by Schelling into

philosophy as a governing principle in the study of matter and of mind,

is not to be confused either with the older use of these terms or with

their current applications to-day[6]. By evolution (or development)

and involution (or envelopment) the earlier speculation on biology had

denoted the view that the organic germ contained _in parvo_ all that

the matured organism showed in large. As the mature bulb of the healthy

hyacinth shows, when cut open, to the naked eye, the stem and flowers

that will issue from it next spring; so in general the seed can be

treated as a miniature organism needing only an increase of bulk to

make it fully visible in details. Growth is thus not accretion, but

explication and enlargement of a microscopic organism subsisting in the

germ.

Evolution, in the present time, and especially since Darwin, means

something more than this. It implies a theory of descent of the variety

of existing organisms from other organisms of a previous age, less

individualised in forms and functions. From comparatively simple and

homogeneous creatures there have issued in the course of ages creatures

of more complex, more highly differentiated structure; and this process

of gradual differentiation may be conceived as going on through an all

but infinite period. At one end we may conceive matter, just endowed

with the faculties of life and organisation, but in a minimal degree;

at the other end of the developmental process, creatures which have

organised within themselves powers, maximal both in range and variety.

The result (so far as we at present go) is a genealogy of organism

which, to quote Darwin, pictures before us a 'great tree of life which

fills with its dead and broken branches the crust of the earth and

covers the surface with its ever branching and beautiful ramifications.'

Even Bugon, seeing how naturally he could regard 'the wolf, the fox,

and the jackal' as 'degenerate species of a single family,' concluded

we could not go wrong in supposing that 'nature could have with

time drawn from a single being all other organised beings.' Erasmus

Darwin (1794) had insisted on the power of 'appetency' in the organs

of a living creature to create and acquire new structures which it

handed down to its posterity. G. R. Treviranus[7] in his _Biology_

(1802-5) had noted the influence of environment, and Jean Lamarck in

his _Philosophie Zoologique_ (1809) had--after assuming that 'nature

created none but the lowest organisms'--maintained that need and use

(or disuse) can so effectively modify a creature that it may even

produce new organs, and give rise by imperceptible degrees to a variety

of creatures as widely divergent as they now appear. E. g. 'The giraffe

owes its long neck to its continued habit of browsing upon trees.' And

gradually it had become recognised by speculators on this subject that,

as Mr. H. Spencer wrote in 1852, 'by small increments of modification

any amount of modification may in time be generated.' Finally, in 1859,

Darwin, with an ample resource of illustrative examples, enforced the

doctrine that the existing fauna and flora of the earth represent the

result of a struggle for existence, protracted during vast ages, in

which those creature's have been preserved (selected to live) which,

among all the variously-endowed offspring of any kind, were best fitted

to appropriate the means of subsistence in the circumstances in which

they for the time found themselves placed. The circumstances of life

on the globe are perpetually varying from place to place and time to

time: progeny never exactly reproduce their parents, and diverge widely

from each other: hence each form of life is perpetually sliding on from

phase to phase, and only those survive which are best adapted to the

new conditions of life.

So far as Darwinism is an attempt to show that the classes of plants

and animals are not a mere juxtaposition and aggregation, but are to be

explained by reference to a single genetic principle, it is in harmony

with the Evolution taught by Schelling and Hegel. Both alike overthrow

the hard and fast lines of division which semi-popular science insists

upon, and restore the continuity of existence. Both regard Nature as

an organic realm, developing by action and re-action within itself,

living a common life in thorough sympathy and solidarity, and not a

mere machine in which the several parts retain without change the

features and functions impressed upon them at creation by some supernal

architect. But they differ in other points. Ordinary Darwinism,

at least, talks as if circumstances and organism were independent

originally, and only brought as it were, incidentally, in contact

and correlation. It fails to keep hold of the fact--of which it is

abstractly aware--that the two act upon and modify each other because

they are members of a larger organism. It forgets, in short, what

Schelling so thoroughly realised, that the organic and inorganic,

ordinarily so called, are both in a wider sense organic. It wants the

courage of recognising its own tacit presuppositions.

But the characteristic difference between the evolution theory of

to-day and that meant by the philosophers is different from this,

though connected with it. 'The assertion,' says Schelling, 'that

the various organisms have formed themselves by gradual development

from one another, is a misconception of an Idea which really lies in

reason[8].' And Hegel no less decidedly asserts that 'Metamorphosis'

(as the term was then applied, e. g. by Goethe, to what we now call

Evolution) really _exists_ as a fact only in the case of the living

individual,--not in the supposed or theoretical continuity of the

species. 'It is an awkward way both ancient and modern speculative

biology have had of presenting the development and transition of one

physical form and sphere into a higher one as an outwardly-actual

production,--which, however, in order to make it clearer, has been

thrown back into the darkness of the past.'[9] Yet notwithstanding

these and even later protests, there is a great charm for many minds in

the evolutionist picture, e. g., of the horse of to-day as the literal

descendant through nearly fifty great stages (called species) from

some creature of the eocene age, which gradually transformed itself in

consequence of innate instability or variability of construction and in

obedience to changes in its environment. But whatever value there may

be in these as yet hypothetical aids to the imagination in grasping and

unifying the variety of organic life, they run on another line from the

philosophical evolution. That evolution is in the _Idea_, the _Notion._

It is the 'fluidity' of terms of thought that is here sought, not

of the kinds of things,--except in a secondary way. And above all,

philosophy does not deal with a problem in time, with a mere sequence;

if it deals with a history of nature, the agents of that history are

powers and forces--and powers which are ideal no less than real.

A nearer approach to the philosophic conception is to be found in the

views which modern physiology takes of the nature of organic structure

and function[10]. In the simplest phases of protoplasm, the apparently

homogeneous mass is really undergoing a series of changes, and indeed

only exists as such, because it is the ever-renewed resultant of

two correlated processes,--a movement up (anabolic change) by which

dead matter is assimilated and built into it, and a movement down

(katabolic changes) by which its composing elements are disintegrated

and left behind, with accompanying liberation of energy. Protoplasm or

'living matter' is the incessantly formed and re-formed thin line on

which these two currents for the moment converge,-a temporary crest

of white foam, as it were, raising itself on the Heraclitean wave of

vicissitude, where all things flow on and nothing abides. But wherever

protoplasm arises and maintains itself on this borderline of ascending

and descending states, it exhibits the three well-known properties of

assimilation, contractility, and sensitiveness. Protoplasm, placed

as it were in the mean between these two processes, is or has the

synthetic power which governs them and keeps them in one. It is no

mere chemical substance, undergoing composition and decomposition,

but rather, if looked at from the somewhat speculative standpoint of

molecular physics, a kind of intricate movement or dance of particles,

a shape or 'form' instinct with the power of producing and reproducing

itself, and, ultimately, in some highly differentiated phases

(nerve-system), with a power of producing and reproducing a world of

imagination.

A philosophy of Nature is only half a philosophy. Its purport is

to set free the spirit in nature, to release intelligence from its

imprisonment in material encasements which hide it from the ordinary

view, and to gather together the _disjecta membra_ of the divine into

the outlines of one continuous organisation. It seeks to spiritualise

nature, i. e. to present the inner idea, unity, and genetic

interdependence of all its phenomena: to delineate _natura formaliter

spectata_ not as a logical skeleton of abstract categories, but in its

organisation and continuous life. There remains the problem of what

Schelling calls 'Transcendental Idealism':--called 'transcendental'

to avoid confusion with the vulgar idealism which supposes the world

to be what it calls a mere 'idea' or phantom of the mind. Schelling's

is on the contrary an 'Ideal-Realism': it 'materialises the laws of

intelligence to laws of nature[11].'

We need not in details consider the genesis of Reality from the action

of the Ego. Substantially it is the same as that given by Fichte.

An activity, which is at once self-limiting and superior to all

limit, rises through stage to stage, from sensation and intuition,

to reflection and intelligence, till it becomes the consciousness of

a world of ob; ective reality. 'Give me,' says the transcendental

philosopher, 'a nature with opposing activities, of which the one

goes to infinity, and the other endeavours to behold itself in this

infinity,--and from that I will show you intelligence arising with the

whole system of its ideas[12].' In the first phase the 'ideal-real'

world arises by the synthetic action of the 'productive intuition,'

Ideas, as it were, live and move: they grow and build up: causality

is neither a category nor a schema, but an intelligent 'form' which

is also a force--an 'idée-force,' They are (in the Hegelian sense)

'Ideas,' i.e. neither merely objective nor merely subjective, but both

at once. But such an ideal world is outside and beyond consciousness:

it belongs to the same region as that higher Ego where there is no

distinction between the Ego I am and the Ego I know. To follow the

movement in this region needs a combination of mental vision and visual

intellect, which Schelling has called the 'Intellectual Intuition.'

It is a power which rising above the materialism of sense yet retains

its realism; which, while intellectual, is free from abstractness.

It is synthetic, and widely different from mere logical analysis.

It is, in short, analogous to the artistic genius: it creates a

quasi-objectivity, an ideal-reality, without which the mere words of

the speculator are meaningless. By means of this 'organ,' philosophy

can 'freely imitate and repeat the original series of actions in which

the one "act" of self-consciousness is evolved[13].

But the 'productive intuition' is, as Kant would say, blind: it is

unconscious in its operation: and it is only after an arrest, a Sabbath

when it surveys and judges its work, that it begins to realise itself

through a process of analysis and reflection which elicits and fixes

the categories that have been operative in it. By this abstraction

intelligence rises out of mere production to intelligent and conscious

production, i.e. to volition, where it has an ideal and realises it.

With volition and voluntary action, objectivity is to appearance

further certified and fortified. It is as active, i. e. as free, and

even moral, agents, that we set forward categorically the reality of

the world. So, too, Fichte had declared. But, as Schelling reminds

us, with this intensified assertion of a law and an ideal to which

the real must and shall correspond,--with the declaration that the

realm of absolute consistency and ideal truth of reason is the true

and real for ever and ever--we come across the fundamental antithesis

of the 'Is' and the 'Ought,5 of the objective and subjective, of

unconscious necessity and self-conscious freedom. With an attempt to

get a philosophy of history,--i. e. of man and mind as the culminating

truth of things, we see ourselves confronted with the opposition of

fatalism and chance. On one hand history is only possible for beings

who have an ideal in view,--one persistent aim and principle which

their work and will is the means of realising. And yet it is an ideal

which only the series of generations, only the whole race, can realise.

Man's license to do or to refrain rests upon a larger, latent, divine

necessity which constrains it. What human agents by their free choice

determine and carry out, is carried out, in the long run, by the force

of an everlasting and unchanging order, to which their wills seem but

a mere plaything. But that man's free agency should thus harmonise

with the constrained uniformities of nature is only possible on the

assumption that both are phenomena of a common ground, or basis of

identity, of an 'absolute identity, in which there is no duplication,

and which for that reason, because the condition of all consciousness

is duplication, can never reach consciousness. This ever-Unconscious,

which, as it were the everlasting Sun in the spirit-kingdom, is hidden

in its own undimmed light, and which, though it is never an object,

still impresses its identity on all free objects, is simultaneously

the same for all intelligences, the invisible "root" of which all

intelligences are only the "powers," and the everlasting mediator

between the self-determining subjective in us and the objective or

percipient,--simultaneously the ground of the uniformity in freedom,

and of the freedom in uniformity of the objective[14].' To rise to the

sense of this Absolute Identity, as common basis of harmony between the

'Ought' and the 'Is,' is to recognise Providence: it is Religion.

But this 'Absolute' is never in history completely revealed--we cannot

_see_ free action coincide with predetermination. Thus if History as

a whole be> conceived as a 'continuous and gradual self-revelation;

of the Absolute,' 'God never _is,_ if _is_ means exhibition; in the

objective world: _if God were, we_ should not be[15].' Nor is the

Absolute so revealed in Nature. Yet, even as the apparent contingency

of human action throws us back on an everlasting necessity which is

yet freedom, so the apparent uniformity of natural order shows us in

organic life the traces of a free self-regulating development. To

apprehend the truth at which both seem to point we want an organ of

intelligence which shall unite in itself the conscious activity of

free production with the unconscious instinct of natural creation.

Such an organ is found in they aesthetic power of genius, in the

Artist. The artistic product is the work of two intimately-conjoined

principles:--of the art (in the narrower sense) which can be taught

and learned, and is exercised consciously and with reflection, and of

that 'poesy in Art,' the unconscious grace of genius which can neither

be handed down nor acquired, but can only be inborn by free gift of

nature. In the work thus brought to birth there is something definite,

precise, and capable of exposition in finite formulae: there is also

something which no 'prose' can ever explicate, something which tells us

of the infinite and eternal, which ever reveals and yet conceals the

Absolute and Perfect. Art, thus springing from 'imagination, the one

sole power by which we can think and conjoin even the contradictory,'

gives objectivity and outward shape to that 'intellectual intuition' by

which the philosopher subjectively (in his own consciousness) sought to

realise to himself the unity of thought and existence.

'To the philosopher,' Schelling concludes, 'Art is supreme, because it

as it were opens to him the Holy of Holies, where in everlasting and

original unity there burns, as it were in one flame, what is parted

asunder in nature and history, and what in life and conduct, no less

than in thinking, must for ever flee apart. The view the philosopher

artificially makes for himself of nature is for Art the original and

natural. What we call nature is a poem which is locked up in strange

and secret characters. Yet could the riddle be disclosed, we should

recognise in it the Odyssey of the mind, which, strangely deceived, in

seeking itself, flees from itself: for through the sense-world there

is a glimpse, only as through words of the meaning, only as through

half-transparent mist of the land %of imagination, after which we

yearn. That splendid picture emerges, as it were, by the removal of the

invisible partition-wall which sunders the actual and the ideal world,

and is only the opening by which those figures and regions of the world

of imagination, that but imperfectly glimmer through the actual, come

forward in all their fulness. Nature is to the artist no more than

it is to the philosopher, viz. the ideal world as it appears under

constant limitations, or only the imperfect reflex of a world which

does not exist outside him, but within him.'

'If it is Art alone, then, which can succeed in making objective

and universally accepted what the philosopher can only exhibit

subjectively, it may also be expected that philosophy, as it was in

the infancy of science born and nourished by poetry, and with it

all those sciences which were by it carried on towards perfection,

will after their completion flow back as so many single streams into

the universal ocean of poetry from which they issued. Nor is it in

general hard to say what will be the means for the return of science

to poetry: for such a means has existed in mythology before this, as

it now seems, irrevocable separation took place. But as to how a new

mythology,--which cannot be the invention of the single poet, but of

a new generation, as it were representing only a single poet,--can

itself arise, is a problem, the solution of which is to be expected

only from the future destinies of the world and the further course of

history[16].'
