Since the time when the foregoing remarks were written I have been

more than once among the spirits, at their own invitation. They do

not improve on acquaintance. Surely no baser delusion ever obtained

dominance over the weak mind of man.

I. REFLECTIONS ON PRAYER AND NATURAL LAW.

1861.

AMID the apparent confusion and caprice of natural phenomena, which

roused emotions hostile to calm investigation, it must for ages have

seemed hopeless to seek for law or orderly relation; and before the

thought of law dawned upon the unfolding human mind these otherwise

inexplicable effects were referred to personal agency. In the fall of

a cataract the savage saw the leap of a spirit, and the echoed

thunder-peal was to him the hammer-clang of an exasperated god.

Propitiation of these terrible powers was the consequence, and

sacrifice was offered to the demons of earth and air.

But observation tends to chasten the emotions and to check those

structural efforts of the intellect which have emotion for their base.

One by one natural phenomena came to be associated with their

proximate causes; the idea of direct personal volition mixing itself

with the economy of nature retreating more and more. Many of us fear

this change. Our religious feelings are dear to us, and we look with

suspicion and dislike on any philosophy, the apparent tendency of

which is to dry them up. Probably every change from ancient savagery

to our present enlightenment has excited, in a greater or less degree,

fears of this kind. But the fact is, that we have not yet determined

whether its present form is necessary to the life and warmth of

religious feeling. We may err in linking the imperishable with the

transitory, and confound the living plant with the decaying pole to

which it clings. My object, however, at present is not to argue, but

to mark a tendency. We have ceased to propitiate the powers of

nature--ceased even to pray for things in manifest contradiction to

natural laws. In Protestant countries, at least, I think it is

conceded that the age of miracles is past.

At an auberge near the foot of the Rhone glacier, I met, in the summer

of 1858, an athletic young priest, who, after a solid breakfast,

including a bottle of wine, informed me that he had come up to 'bless

the mountains.' This was the annual custom of the place. Year by year

the Highest was entreated, by official intercessors, to make such

meteorological arrangements as should ensure food and shelter for the

flocks and herds of the Valaisians. A diversion of the Rhone, or a

deepening of the river's bed, would, at the time I now mention, have

been of incalculable benefit to the inhabitants of the valley. But

the priest would have shrunk from the idea of asking the Omnipotent to

open a new channel for the river, or to cause a portion of it to flow

over the Grimsel pass, and down the valley of Oberhasli to Brientz.

This he would have deemed a miracle, and he did not come to ask the

Creator to perform miracles, but to do something which he manifestly

thought lay quite within the bounds of the natural and non-miraculous.

A Protestant gentleman who was present at the time smiled at this

recital. He had no faith in the priest's blessing; still, he deemed

his prayer different in kind from a request to open a new river-cut,

or to cause the water to flow up-hill.

In a similar manner the same Protestant gentleman would doubtless

smile at the honest Tyrolese priest, who, when he feared the bursting

of a glacier dam, offered the sacrifice of the Mass upon the ice as a

means of averting the calamity. That poor man did not expect to

convert the ice into adamant, or to strengthen its texture, so as to

enable it to withstand the pressure of the water; nor did he expect

that his sacrifice would cause the stream to roll back upon its source

and relieve him, by a miracle, of its presence. But beyond the

boundaries of his knowledge lay a region where rain was generated, he

knew not how. He was not so presumptuous as to expect a miracle, but

he firmly believed that in yonder cloud-land matters could be so

arranged, without trespass on the miraculous, that the stream which

threatened him and his people should be caused to shrink within its

proper bounds.

Both these priests fashioned that which they did not understand to

their respective wants and wishes. In their case imagination came

into play, uncontrolled by a knowledge of law. A similar state of

mind was long prevalent among mechanicians. Many of these, among whom

were to be reckoned men of consummate skill, were occupied a century

ago with the question of perpetual motion. They aimed at constructing

a machine which should execute work without the expenditure of power;

and some of them went mad in the pursuit of this object. The faith in

such a consummation, involving, as it did, immense personal profit to

the inventor, was extremely exciting, and every attempt to destroy

this faith was met by bitter resentment on the part of those who held

it. Gradually, however, as men became more and more acquainted with

the true functions of machinery, the dream dissolved. The hope of

getting work out of mere mechanical combinations disappeared: but

still there remained for the speculator a cloud-land denser than that

which filled the imagination of the Tyrolese priest, and out of which

he still hoped to evolve perpetual motion. There was the mystic store

of chemic force, which nobody understood; there were heat and light,

electricity and magnetism, all competent to produce mechanical motion.

[Footnote: See Helmholtz: 'Wechselwirkung der Naturkräfte.'] Here,

then, was the mine in which our gem must be sought. A modified and

more refined form of the ancient faith revived; and, for aught I know,

a remnant of sanguine designers may at the present moment be engaged

on the problem which like-minded men in former ages left unsolved.

And why should a perpetual motion, even under modern conditions, be

impossible? The answer to this question is the statement of that

great generalisation of modern science, which is known under the name

of the Conservation of Energy. This principle asserts that no power

can make its appearance in nature without an equivalent expenditure of

some other power; that natural agents are so related to each other as

to be mutually convertible, but that no new agency is created. Light

runs into heat; heat into electricity; electricity into magnetism;

magnetism into mechanical force; and mechanical force again into light

and heat. The Proteus changes, but he is ever the same; and his

changes in nature, supposing no miracle to supervene, are the

expression, not of spontaneity, but of physical necessity. A

perpetual motion, then, is deemed impossible, because it demands the

creation of energy, whereas the principle of Conservation is--no

creation, but infinite conversion.

It is an old remark that the law which moulds a tear also rounds a

planet. In the application of law in nature the terms great and small

are unknown. Thus the principle referred to teaches us that the

Italian wind, gliding over the crest of the Matterhorn, is as firmly

ruled as the earth in its orbital revolution round the sun; and that

the fall of its vapour into clouds is exactly as much a matter of

necessity as the return of the seasons. The dispersion, therefore, of

the slightest mist by the special volition of the Eternal, would be as

much a miracle as the rolling of the Rhone over the Grimsel

precipices, down the valley of Hash to Meyringen and Brientz.

It seems to me quite beyond the present power of science to

demonstrate that the Tyrolese priest, or his colleague of the Rhone

valley, asked for an 'impossibility' in praying for good weather; but

Science can demonstrate the incompleteness of the knowledge of nature

which limited their prayers to this narrow ground; and she may lessen

the number of instances in which we 'ask amiss,' by showing that we

sometimes pray for the performance of a miracle when we do not intend

it. She does assert, for example, that without a disturbance of

natural law, quite as serious as the stoppage of an eclipse, or the

rolling of the river Niagara up the Falls, no act of humiliation,

individual or national, could call one shower from heaven, or deflect

towards us a single beam of the sun.

Those, therefore, who believe that the miraculous is still active in

nature, may, with perfect consistency, join in our periodic prayers

for fair weather and for rain: while those who hold that the age of

miracles is past, will, if they be consistent, refuse to join in these

petitions. And these latter, if they wish to fall back upon such a

justification, may fairly urge that the latest conclusions of science

are in perfect accordance with the doctrine of the Master himself,

which manifestly was that the distribution of natural phenomena is not

affected by moral or religious causes. 'He maketh His sun to rise on

the evil and on the good, and sendeth rain on the just and on the

unjust.' Granting 'the power of Free Will in man,' so strongly claimed

by Professor Mansel in his admirable defence of the belief in

miracles, and assuming the efficacy of free prayer to produce changes

in external nature, it necessarily follows that natural laws are more

or less at the mercy of man's volition, and no conclusion founded on

the assumed permanence of those laws would be worthy of confidence.

It is a wholesome sign for England that she numbers among her clergy

men wise enough to understand all this, and courageous enough to act

up to their knowledge. Such men do service to public character, by

encouraging a manly and intelligent conflict with the real causes of

disease and scarcity, instead of a delusive reliance on supernatural

aid. But they have also a value beyond this local and temporary one.

They prepare the public mind for changes, which though inevitable,

could hardly, without such preparation, be wrought without violence.

Iron is strong; still, water in crystallising will shiver an iron

envelope, and the more unyielding the metal is, the worse for its

safety. There are in the world men who would encompass philosophic

speculation by a rigid envelope, hoping thereby to restrain it, but in

reality giving it explosive force. In England, thanks to men of the

stamp to which I have alluded, scope is gradually given to thought for

changes of aggregation, and the envelope slowly alters its form, in

accordance with the necessities of the time.

*****

The proximate origin of the foregoing slight article, and probably the

remoter origin of the next following one, was this. Some years ago, a

day of prayer and humiliation, on account of a bad harvest, was

appointed by the proper religious authorities; but certain clergymen

of the Church of England, doubting the wisdom of the demonstration,

declined to join in the services of the day. For this act of

nonconformity they were severely censured by some of their brethren.

Rightly or wrongly, my sympathies were on the side of these men; and,

to lend them a helping hand in their struggle against odds, I inserted

the foregoing chapter in a little book entitled 'Mountaineering in

1861.' Some time subsequently I received from a gentleman of great

weight and distinction in the scientific world, and, I believe, of

perfect orthodoxy in the religious one, a note directing my attention

to an exceedingly thoughtful article on Prayer and Cholera in the

'Pall Mall Gazette.' My eminent correspondent deemed the article a

fair answer to the remarks made by me in 1861. I, also, was struck by

the temper and ability of the article, but I could not deem its

arguments satisfactory, and in a short note to the editor of the 'Pall

Mall Gazette' I ventured to state so much. This letter elicited some

very able replies, and a second leading article was also devoted to

the subject. In answer to all, I risked the publication of a second

letter, and soon afterwards, by an extremely courteous note from the

editor, the discussion was closed.

Though thus stopped locally, the discussion flowed in other

directions. Sermons were preached, essays were published, articles

were written, while a copious correspondence occupied the pages of

some of the religious newspapers. It gave me sincere pleasure to

notice that the discussion, save in a few cases where natural

coarseness had the upper hand, was conducted with a minimum of

vituperation. The severity shown was hardly more than sufficient to

demonstrate earnestness, while gentlemanly feeling was too predominant

to permit that earnestness to contract itself to bigotry or to clothe

itself in abuse. It was probably the memory of this discussion which

caused another excellent friend of mine to recommend to my perusal the

exceedingly able work which in the next article I have endeavoured to

review.

Mr. Mozley's book belongs to that class of writing of which Butler may

be taken as the type. It is strong, genuine argument about difficult

matters, fairly tracing what is difficult, fairly trying to grapple,

not with what appears the gist and strong point of a question, but

with what really at bottom is the knot of it. It is a book the

reasoning of which may not satisfy everyone... But we think it is a

book for people who wish to see a great subject handled on a scale

which befits it, and with a perception of its real elements. It is a

book which will have attractions for those who like to see a powerful

mind applying itself, without shrinking or holding back, without trick

or reserve or show of any kind, as a wrestler closes body to body with

his antagonist, to the strength of an adverse and powerful

argument.--Times, Tuesday, June 5, 1866.

We should add, that the faults of the work are wholly on the surface

and in the arrangement; that the matter is as solid and as logical as

that of any book within recent memory, and that it abounds in striking

passages, of which we have scarcely been able even to give a sample.

No future arguer against miracles can afford to pass it

over.--SATURDAY REVIEW, September 15, 1866.

II MIRACLES AND SPECIAL PROVIDENCES.

[Footnote: Fortnightly Review, New Series, vol. i. p. 645.]

1867.

IT is my privilege to enjoy the friendship of a select number of

religious men, with whom I converse frankly upon theological subjects,

expressing without disguise the notions and opinions I entertain

regarding their tenets, and hearing in return these notions and

opinions subjected to criticism. I have thus far found them liberal

and loving men, patient in hearing, tolerant in reply, who know how to

reconcile the duties of courtesy with the earnestness of debate. From

one of these, nearly a year ago, I received a note, recommending

strongly to my attention the volume of 'Bampton Lectures' for 1865, in

which the question of miracles is treated by Mr. Mozley. Previous to

receiving this note, I had in part made the acquaintance of the work

through an able and elaborate review of it in the 'Times.' The

combined effect of the letter and the review was to make the book the

companion of my summer tour in the Alps. There, during the wet and

snowy days which were only too prevalent in 1866, and during the days

of rest interpolated between days of toil, I made myself more

thoroughly conversant with Mr. Mozley's volume. I found it clear and

strong--an intellectual tonic, as bracing and pleasant to my mind as

the keen air of the mountains was to my body. From time to time I

jotted down thoughts regarding it, intending afterwards to work them

up into a coherent whole. Other duties, however, interfered with the

complete carrying out of this intention, and what I wrote last summer

I now publish, not hoping to be able, within any reasonable time, to

render my defence of scientific method more complete.

Mr. Mozley refers at the outset of his task to the movement against

miracles which of late years has taken place, and which determined his

choice of a subject. He acquits modern science of having had any

great share in the production of this movement. The objection against

miracles, he says, does not arise from any minute knowledge of the

laws of nature, but simply because they are opposed to that plain and

obvious order of nature which everybody sees. The present movement

is, he thinks, to be ascribed to the greater earnestness and

penetration of the present age. Formerly miracles were accepted

without question, because without reflection; but the exercise of the

'historic imagination' is a characteristic of our own time. Men are

now accustomed to place before themselves vivid images of historic

facts; and when a miracle rises to view, they halt before the

astounding occurrence, and, realising it with the same clearness as if

it were now passing before their eyes, they ask themselves, 'Can this

have taken place?' In some instances the effort to answer this

question has led to a disbelief in miracles, in others to a

strengthening of belief. The aim of Mr. Mozley's lectures is to show

that the strengthening of belief is the logical result which ought to

follow from the examination of the facts.

Attempts have been made by religious men to bring the Scripture

miracles within the scope of the order of nature, but all such

attempts are rejected by Mr. Mozley as utterly futile and wide of the

mark. Regarding miracles as a necessary accompaniment of a revelation,

their evidential value in his eyes depends entirely upon their

deviation from the order of nature. Thus deviating, they suggest and

illustrate a power higher than nature, a 'personal will;' and they

commend the person in whom this power is vested as a messenger from on

high. Without these credentials such a messenger would have no right

to demand belief, even were his assertions regarding his Divine

mission backed by a holy life. Nor is it by miracles alone that the

order of nature is, or may be, disturbed. The material universe is

also the arena of 'special providences.' Under these two heads Mr.

Mozley distributes the total preternatural. One form of the

preternatural may shade into the other, as one colour passes into

another in the rainbow; but, while the line which divides the

specially providential from the miraculous cannot be sharply drawn,

their distinction broadly expressed is this: that, while a special

providence can only excite surmise more or less probable, it is 'the

nature of a miracle to give proof, as distinguished from surmise, of

Divine design.'

Mr. Mozley adduces various illustrations of what he regards to be

special providences, as distinguished from miracles. 'The death of

Arius,' he says, 'was not miraculous, because the coincidence of the

death of a heresiarch taking place when it was peculiarly advantageous

to the orthodox faith ... was not such as to compel the inference

of extraordinary Divine agency; but it was a special providence,

because it carried a reasonable appearance of it. The miracle of the

Thundering Legion was a special providence, but not a miracle, for

the same reason, because the coincidence of an instantaneous fall of

rain, in answer to prayer, carried some appearance, but not proof, of

preternatural agency.'

The eminent lecturer's remarks on this head brought to my recollection

certain narratives published in Methodist magazines, which I used to

read with avidity when a boy. The general title of these exciting

stories, if I remember right, was 'The Providence of God asserted,'

and in them the most extraordinary escapes from peril were recounted

and ascribed to prayer, while equally wonderful instances of calamity

were adduced as illustrations of Divine retribution. In such

magazines, or elsewhere, I found recorded the case of the celebrated

Samuel Hick, which, as it illustrates a whole class of special

providences approaching in conclusiveness to miracles, is worthy of

mention here. It is related of this holy man that, on one occasion,

flour was lacking to make the sacramental bread. Grain was present,

and a windmill was present, but there was no wind to grind the corn.

With faith undoubting, Samuel Hick prayed to the Lord of the winds:

the sails turned, the corn was ground, after which the wind ceased.

According to the canon of the Bampton Lecturer, this, though carrying

a strong appearance of an immediate exertion of Divine energy, lacks

by a hair's-breadth the quality of a miracle. For the wind _might_ have

arisen, and _might_ have ceased, in the ordinary course of nature. Hence

the occurrence did not 'compel the inference of extraordinary Divine

agency.' In like manner Mr. Mozley considers that 'the appearance of

the cross to Constantine was a miracle, or a special providence,

according to what account of it we adopt. As only a meteoric

appearance in the shape of a cross it gave some token of preternatural

agency, but not full evidence.'

In the Catholic canton of Switzerland where I now write, and still

more among the pious Tyrolese, the mountains are dotted with shrines,

containing offerings of all kinds, in acknowledgment of special

mercies--legs, feet, arms, and hands--of gold, silver, brass, and

wood, according as worldly possessions enabled the grateful heart to

express its indebtedness. Most of these offerings are made to the

Virgin Mary. They are recognitions of 'special providences,' wrought

through the instrumentality of the Mother of God. Mr. Mozley's

belief, that of the Methodist chronicler, and that of the Tyrolese

peasant, are substantially the same. Each of them assumes that

nature, instead of flowing ever onward in the uninterrupted rhythm of

cause and effect, is mediately ruled by the free human will. As

regards _direct_ action upon natural phenomena, man's wish and will, as

expressed in prayer, are confessedly powerless; but prayer is the

trigger which liberates the Divine power, and to this extent, if the

will be free, man, of course, commands nature.

Did the existence of this belief depend solely upon the material

benefits derived from it, it could not, in my opinion, last a decade.

As a purely objective fact, we should soon see that the distribution

of natural phenomena is unaffected by the merits or the demerits of

men; that the law of gravitation crushes the simple worshippers of

Ottery St. Mary, while singing their hymns, just as surely as if they

were engaged in a midnight brawl. The hold of this belief upon the

human mind is not due to outward verification, but to the inner

warmth, force, and elevation with which it is commonly associated. It

is plain, however, that these feelings may exist under the most

various forms. They are not limited to Church of England

Protestantism--they are not even limited to Christianity. Though less

refined, they are certainly not less strong in the heart of the

Methodist and the Tyrolese peasant than in the heart of Mr. Mozley.

Indeed, those feelings belong to the primal powers of man's nature. A

'sceptic' may have them. They find vent in the battle-cry of the

Moslem. They take hue and form in the hunting-grounds of the Red

Indian; and raise all of them, as they raise the Christian, upon a

wave of victory, above the terrors of the grave.
