XII. Design In Nature.

_Reader._ Everything in nature speaks of God; but you, doctor, seem quite

insensible to the eloquence of creation.

_Büchner._ I deny the eloquence of creation. Indeed, “design in nature has

ever been, and is still, one of the chief arguments in favor of the theory

which ascribes the origin and preservation of the world to a ruling and

organizing creative power. Every flower which unfolds its blossoms, every

gust of wind which agitates the air, every star which shines by night,

every wound which heals, every sound, everything in nature, affords to the

believing teleologist an opportunity for admiring the unfathomable wisdom

of that higher power. Modern science has pretty much emancipated itself

from such empty notions, and abandons these innocent studies to such as

delight in contemplating nature rather with the eyes of the feeling than

with those of the intellect” (p. 89).

_Reader._ This is no reason why you should blind yourself to the evidence

of the facts. Every one knows that Masonic science hates teleology. No

wonder at that. This science emancipates itself, not from empty notions,

as you say, but from the very laws of reasoning. Free thought would cease

to be free, if it did not emancipate itself from logic. Yet, since free‐

thinkers “abandon to us the innocent study” of teleology, would it not be

prudent in them to avoid talking on what they are unwilling to study? How

can they know that we contemplate nature “rather with the eyes of the

feeling than with those of the intellect”? Do they suppose that order and

design are objects of the feeling rather than of the intellect?

_Büchner._ I will tell you what our conviction is. “The combination of

natural materials and forces must, in giving rise to the variety of

existing forms, have at the same time become mutually limited and

determined, and must have produced corresponding contrivances, which,

superficially considered, appear to have been caused by an external

power.” Our reflecting reason is the sole cause of this apparent design,

which is nothing but the necessary consequence of the combination of

natural materials and forces. Thus, as Kant says, “our intellect admires a

wonder which it has created itself” (p. 90).

_Reader._ Beware of blunders, doctor! You have just said that our notion

of design in nature was caused by our feeling, not by our intellect; but

you now say that the sole cause of that notion is our reflecting reason,

and maintain, on Kant’s authority, that the same notion is a creation of

our intellect. Can contradiction be more evident?

Again, if our reflecting reason is the sole cause of our perception of

design in nature, surely we are right in admitting that there is design in

nature, and you are wrong in denying it. For, if the design were only

_apparent_, as you pretend, imagination might be fascinated by it, but

“reflecting reason” would never cause us to perceive it. On the other

hand, if you distrust “reflecting reason,” what else will you trust in its

stead?

Moreover, how did you not observe that Kant’s proposition, “Our intellect

admires a wonder which it has created itself,” contains a false

supposition? The intellect cannot create to itself any notion of design;

it can only perceive it in the things themselves: and it would never

affirm the existence of design in nature, unless it perceived its

objective reality. Hence our intellect admires a wonder which it

perceives, not a wonder which it creates.

Furthermore, you wish us to believe that what we term design “is nothing

but a necessary consequence of some combinations.” But why did you omit

that all such combinations presuppose definite conditions, and that these

conditions originally depend on the will of the Creator? Your book on

_Force and Matter_ is nothing but a necessary consequence of a combination

of types, ink, and paper. Does it follow that the book is not the work of

a designing doctor? You see how defective your reasoning is. You have

nearly succeeded in proving the contrary of what you intended.

_Büchner._ But “how can we speak of design, knowing the objects only in

one form and shape, and having no idea how they would appear to us in any

other? What natural contrivance is there which might not be imagined to be

rendered more perfect in design? We admire natural objects without

considering what an infinite variety of other contrivances and forms has

slumbered, and is still dormant, in the lap of nature. It depends on an

accident whether or not they will enter into existence” (p. 90).

_Reader._ I apprehend, doctor, that your notion of design is neither clear

nor correct. The “form and shape” of the objects is not what _we_ call

design. Design, in nature, is _the ordination of all things to an end_. It

is therefore the natural aptitude of things to a definite end, and not

their form or shape, that reveals the existence of design in nature. It is

not even the absolute perfection of a thing that reveals design: it is

only its relative perfection, that is, its proportion to the end for which

it is created. Hence we have the right to admire natural objects for their

adaptation to certain ends, without considering the infinite variety of

other contrivances slumbering in the lap of nature. For, if the existing

contrivances are proportionate to their ends, there is design, whatever we

may say of the possibility of other contrivances, and even of other words.

_Büchner._ “Numbers of arrangements in nature, apparently full of design,

are nothing but the result of the influence of external natural

conditions” (p. 90).

_Reader._ Yes; but these natural conditions are themselves the result of

design, since they are all controlled by a superior mind.

_Büchner._ “Animals inhabiting the north have a thicker fur than those of

the south; and likewise the hair and feathers of animals become thicker in

winter and fall out in summer. Is it not more natural to consider these

phenomena as the effect of changes in the temperature, than to imagine a

heavenly tailor who takes care of the summer and winter wardrobes of the

various animals? The stag was not endowed with long legs to enable him to

run fast, but he runs fast because his legs are long” (p. 91).

_Reader._ These remarks are puerile, doctor, and I might dispense with

answering them; yet I observe that, as cold does not foster vegetation, it

is not in the north, but in the south, that the fur of animals should grow

thicker. At any rate, the “heavenly tailor,” who clothes the lilies of the

field, does not forget the wardrobe of animals, whether in the north or in

the south, in summer or in winter; for his is the world, and from his hand

the needs of every creature are supplied. As to the stag, you are likewise

mistaken. “He runs fast because his legs are long”; but how does it follow

from this that he was not endowed with long legs to enable him to run

fast? Does the one exclude the other? Would you say that your works are

known because they have been published, and therefore they have not been

published to make them known? Your blunder is evident.

_Büchner._ “Things are just as they are, and we should not have found them

less full of design had they been different” (p. 91).

_Reader._ This, if true, would prove that our “reflecting reason” cannot

exclude design from creation. If things had been different, the design

would have been different. Even conflicting arrangements may be full of

design; even the destruction of the best works of nature may be full of

design: for the Author of nature is at liberty to do with it as he

pleases. If, for instance, all the new‐born babies were hereafter to be

males, we could not escape the consequence that the Author of nature

designed to put an end to human generation. Whatever may be the order of

things, we cannot deny design without insulting the wisdom of our Maker

and Lord.

This consideration suffices to answer all your queries and objections.

“Nature,” you say, “has produced a number of beings and contrivances in

which no design can be detected” (p. 94). What of that? Can you deny that

men act with some design, only because you cannot detect it? There are

beings, you add, “which are frequently more apt to disturb than to promote

the natural order of things” (_ibid._) This merely shows that the natural

order of things is changeable—a truth which you had the courage to deny

when speaking of miracles.

“The existence of dangerous animals has ever been a thorn in the side of

theologians, and the most comical arguments have been used to justify

their existence” (_ibid._) This is not true. No theologian has ever denied

that dangerous animals fulfil some design in nature. And as to “comical

arguments,” I think, doctor, that it is in your pages that we can best

find them. “We know, on the other hand, that very innocent, or even

useful, animals have become extinct, without nature taking any means to

preserve their existence” (p. 95). This proves nothing at all. If God’s

design could be fulfilled with their extinction, why should they have been

preserved? “For what purpose are the hosts of diseases and of physical

evils in general? Why that mass of cruelties and horrors which nature

daily and hourly practises on her creatures? Could a being acting from

goodness and benevolence endow the cat, the spider, and man with a nature

capable of these horrors and cruelties?” (p. 96). This is the dark side of

the picture; and yet there is design in all this. If I wished to make a

“comical argument,” I might say that “the hosts of diseases” are, after

all, very profitable to the M.D., who cannot live without them. But the

true answer is, that the present order of things, as even the pagan

philosophers recognized, is designed as a period of probation preparatory

to a better life. We now live on a field of battle, amid trials calculated

to stir up our energies and to mend or improve our character. We sow in

tears, that we may reap in joy. Such is the design of a Being “acting from

goodness and benevolence.” You do not understand this; but such is the

truth. As to cats and spiders, you must bear in mind that they are not

worse than the wolf, the tiger, or other animals providing for their own

subsistence by the destruction of other living beings. If this be

“cruelty,” how can you countenance it yourself by allowing the appearance

at your table of killed animals?

Your other remarks are scarcely worthy of being quoted, as they prove

nothing but your impertinence and presumption. You seem to put to God the

dilemma: “Either let Büchner know all the secrets of your providence, or

he will rebel against you, and even deny your existence.” You ask, Why

this and why that? And because your weak brain fails to suggest the

answer, you immediately conclude that things happen to be what they are,

without a superior mind controlling their course. This is nice logic

indeed! “Why should the vertebral column of man terminate in an appendage

perfectly useless to him?” “Why should certain animals possess the organs

of both sexes?” “Why are certain other animals so prolific that in a few

years they might fill the seas and cover the earth, and find no more space

or materials for their offspring?” “Why does nature produce monsters?”

These questions may or may not be answered; but our ignorance is not the

measure of things, and the existence of design in nature remains an

unquestionable fact. Is not the very structure of our own bodies a

masterpiece of design? A physician, like you, cannot plead ignorance on

the subject.

_Büchner._ Yet nature cannot have a design in producing monstrosities. “I

saw in a veterinary cabinet a goat fully developed in every part, but born

without a head. Can we imagine anything more absurd than the development

of an animal the existence of which is impossible from the beginning?

Prof. Lotze of Göttingen surpasses himself in the following remarks on

monstrosities: ‘If the fœtus is without a brain, it would be but

judicious, in a force having a free choice, to suspend its action, as this

deficiency cannot be compensated. But, inasmuch as the formative forces

continue their action, that such a miserable and purposeless creature may

exist for a time, appears to us strikingly to prove that the final result

always depends upon the disposition of purely mechanical definite forces,

which, once set in motion, proceed straight on, according to the law of

inertia, until they meet with an obstruction.’ This is plain language” (p.

99). Again, monstrosities “may be produced artificially by injuries done

to the fœtus or to the ovum. Nature has no means of remedying such an

injury. The impulse once given is, on the contrary, followed in a false

direction, and in due time a monstrosity is produced. The purely

mechanical process, in such cases, can be easily recognized. Can the idea

of a conscious power acting with design be reconciled with such a result?

And is it possible that the hand of the Creator should thus be bound by

the arbitrary act of man?” (pp. 101, 102).

_Reader._ That nature “cannot have a design in producing monstrosities” is

a groundless assertion, as nature tends always to produce perfect beings,

though sometimes its work is marred by obstacles which it has no power to

remove. You saw “a goat fully developed in every part, but born without a

head.” Here the design is evident. Nature wished to produce a perfect goat

as usual, but failed. “If the fœtus is without a brain, it would be

judicious, in a force having a free choice, to suspend its action.” This

is another groundless assertion; for, if by _force_ you mean the forces of

matter, they have no free choice, and cannot suspend their action; and if

by _force_ you mean God, you presume too much, as you do not know his

design. A fœtus without a brain, like a goat without a head, proclaims the

imperfection of natural causes; and this very imperfection proclaims their

contingency and the existence of a Creator. Thus, a fœtus without a brain

may be the work of design; for God’s design is not to raise nature above

all deficiencies, but to show his infinite perfection in the works of an

imperfect nature. That “the hand of the Creator should be bound by the

arbitrary act of men” is a third groundless assertion. Man may injure the

fœtus, and God can restore it to a healthy condition; but nothing obliges

him to do so. If he did it, it would be a miracle; and miracles are not in

the order of nature. It follows that, when monstrosities are produced,

they are not merely the result of mechanical forces, but also of God’s

action, without which no causation is possible.

But you ask, “Can the idea of a conscious power acting with design be

reconciled with such a result?” I answer that it can be reconciled very

well. In fact, those effects which proceed directly from God alone, must

indeed be perfect according to their own kind, inasmuch as God’s working

is never exposed to failure; but those effects which do not proceed

directly from God alone, but are produced by creatures with God’s

assistance, may be imperfect, ugly, and monstrous. You may have a

beautiful hand; but, if you write with a bad pen, your writing will not be

beautiful. You may be a great pianist; but, if your instrument is out of

tune, your music will be detestable. Whenever two causes, of which the one

is instrumental to the other, concur to the production of the same effect,

the imperfection of the instrumental cause naturally entails the

imperfection of the effect. God’s action is perfect; but the action of his

instruments may be imperfect; and it is owing to such an imperfection that

the result may be a monstrosity.

But, to complete this explanation, it is necessary to add that, in the

production of their natural effects, creatures are more than instrumental.

The primary cause, God, and the secondary causes, creatures, are both

_principal_ causes of natural effects; though the latter are subordinate

to the influence of the former. Both God and the creature are total

causes; that is, the effect entirely depends on the secondary, as it

entirely depends on the primary cause, though in a different manner; for

the influx of the primary cause is general, while that of the secondary

cause is particular. Hence these two causes bear to the effect produced by

them the same relation as two premises bear to their conclusion. God’s

influence is to the effect produced what a general principle or a major

proposition is to the conclusion; whilst the creature’s influence is to

the same effect what a minor proposition or the application of the general

principle is to the conclusion. Take, for instance, the general truth,

“Virtue is a rational good,” as a major proposition. This general truth

may be applied in different manners, and lead to different conclusions,

good or bad, according as the application is right or wrong. If you

subsume, “Temperance is a virtue,” you will immediately obtain the good

conclusion that “Temperance is a rational good.” But, if you subsume,

“Pride is a virtue,” you will reach the monstrous conclusion that “Pride

is a rational good.” Now, this conclusion, however monstrous, could not be

drawn without the general principle; and yet its monstrosity does not

arise from the general principle, but only from its wrong application.

Thus the general principle remains good and true in spite of the bad and

false conclusion. And in the same manner the influence of the first cause

on natural effects remains good and perfect, though the effects

themselves, owing to the influence of the secondary causes, are imperfect

and monstrous.

You now understand, I hope, how the exceptional production of

monstrosities can be reconciled with the idea of a conscious power acting

with design.
