III: SCIENCE AND PSEUDO-SCIENCE

[1887]

In the opening sentences of a contribution to the last number of this

Review,[20] the Duke of Argyll has favoured me with a lecture on the

proprieties of controversy, to which I should be disposed to listen

with more docility if his Grace's precepts appeared to me to be based

upon rational principles, or if his example were more exemplary.

With respect to the latter point, the Duke has thought fit to entitle

his article "Professor Huxley on Canon Liddon," and thus forces into

prominence an element of personality, which those who read the paper

which is the object of the Duke's animadversions will observe I have

endeavoured, most carefully, to avoid. My criticisms dealt with a

report of a sermon, published in a newspaper, and thereby addressed to

all the world. Whether that sermon was preached by A or B was not a

matter of the smallest consequence; and I went out of my way to

absolve the learned divine to whom the discourse was attributed from

the responsibility for statements which, for anything I knew to the

contrary, might contain imperfect, or inaccurate, representations of

his views. The assertion that I had the wish, or was beset, by any

"temptation to attack" Canon Liddon is simply contrary to fact.

But suppose that if, instead of sedulously avoiding even the

appearance of such attack, I had thought fit to take a different

course; suppose that, after satisfying myself that the eminent

clergyman whose name is paraded by the Duke of Argyll had really

uttered the words attributed to him from the pulpit of St. Paul's,

what right would any one have to find fault with my action on grounds

either of justice, expediency, or good taste?

Establishment has its duties as well as its rights. The clergy of a

State Church enjoy many advantages over those of unprivileged and

unendowed religious persuasions; but they lie under a correlative

responsibility to the State, and to every member of the body politic.

I am not aware that any sacredness attaches to sermons. If preachers

stray beyond the doctrinal limits set by lay lawyers, the Privy

Council will see to it; and, if they think fit to use their pulpits

for the promulgation of literary, or historical, or scientific errors,

it is not only the right, but the duty, of the humblest layman, who

may happen to be better informed, to correct the evil effects of such

perversion of the opportunities which the State affords them; and such

misuse of the authority which its support lends them. Whatever else it

may claim to be, in its relations with the State, the Established

Church is a branch of the Civil Service; and, for those who repudiate

the ecclesiastical authority of the clergy, they are merely civil

servants, as much responsible to the English people for the proper

performance of their duties as any others.

The Duke of Argyll tells us that the "work and calling" of the clergy

prevent them from "pursuing disputation as others can." I wonder if

his Grace ever reads the so-called "religious" newspapers. It is not

an occupation which I should commend to any one who wishes to employ

his time profitably; but a very short devotion to this exercise will

suffice to convince him that the "pursuit of disputation," carried to

a degree of acrimony and vehemence unsurpassed in lay controversies,

seems to be found quite compatible with the "work and calling" of a

remarkably large number of the clergy.

Finally, it appears to me that nothing can be in worse taste than the

assumption that a body of English gentlemen can, by any possibility,

desire that immunity from criticism which the Duke of Argyll claims

for them. Nothing would be more personally offensive to me than the

supposition that I shirked criticism, just or unjust, of any lecture I

ever gave. I should be utterly ashamed of myself if, when I stood up

as an instructor of others, I had not taken every pains to assure

myself of the truth of that which I was about to say; and I should

feel myself bound to be even more careful with a popular assembly, who

would take me more or less on trust, than with an audience of

competent and critical experts.

I decline to assume that the standard of morality, in these matters,

is lower among the clergy than it is among scientific men. I refuse to

think that the priest who stands up before a congregation, as the

minister and interpreter of the Divinity, is less careful in his

utterances, less ready to meet adverse comment, than the layman who

comes before his audience, as the minister and interpreter of nature.

Yet what should we think of the man of science who, when his ignorance

or his carelessness was exposed, whined about the want of delicacy of

his critics, or pleaded his "work and calling" as a reason for being

let alone?

No man, nor any body of men, is good enough, or wise enough, to

dispense with the tonic of criticism. Nothing has done more harm to

the clergy than the practice, too common among laymen, of regarding

them, when in the pulpit, as a sort of chartered libertines, whose

divagations are not to be taken seriously. And I am well assured that

the distinguished divine, to whom the sermon is attributed, is the

last person who would desire to avail himself of the dishonouring

protection which has been superfluously thrown over him.

So much for the lecture on propriety. But the Duke of Argyll, to whom

the hortatory style seems to come naturally, does me the honour to

make my sayings the subjects of a series of other admonitions, some on

philosophical, some on geological, some on biological topics. I can

but rejoice that the Duke's authority in these matters is not always

employed to show that I am ignorant of them; on the contrary, I meet

with an amount of agreement, even of approbation, for which I proffer

such gratitude as may be due, even if that gratitude is sometimes

almost overshadowed by surprise.

I am unfeignedly astonished to find that the Duke of Argyll, who

professes to intervene on behalf of the preacher, does really, like

another Balaam, bless me altogether in respect of the main issue.

I denied the justice of the preacher's ascription to men of science of

the doctrine that miracles are incredible, because they are violations

of natural law; and the Duke of Argyll says that he believes my

"denial to be well-founded. The preacher was answering an objection

which has now been generally abandoned." Either the preacher knew this

or he did not know it. It seems to me, as a mere lay teacher, to be a

pity that the "great dome of St. Paul's" should have been made to

"echo" (if so be that such stentorian effects were really produced) a

statement which, admitting the first alternative, was unfair, and,

admitting the second, was ignorant.[21]

Having thus sacrified one half of the preacher's arguments, the Duke

of Argyll proceeds to make equally short work with the other half. It

appears that he fully accepts my position that the occurrence of those

events, which the preacher speaks of as catastrophes, is no evidence

of disorder, inasmuch as such catastrophes may be necessary occasional

consequences of uniform changes. Whence I conclude, his Grace agrees

with me, that the talk about royal laws "wrecking" ordinary laws may

be eloquent metaphor, but is also nonsense.

And now comes a further surprise. After having given these superfluous

stabs to the slain body of the preacher's argument, my good ally

remarks, with magnificent calmness: "So far, then, the preacher and

the professor are at one." "Let them smoke the calumet." By all means:

smoke would be the most appropriate symbol of this wonderful attempt

to cover a retreat. After all, the Duke has come to bury the preacher,

not to praise him; only he makes the funeral obsequies look as much

like a triumphal procession as possible.

So far as the questions between the preacher and myself are concerned,

then, I may feel happy. The authority of the Duke of Argyll is ranged

on my side. But the Duke has raised a number of other questions, with

respect to which I fear I shall have to dispense with his

support--nay, even be compelled to differ from him as much, or more,

than I have done about his Grace's new rendering of the "benefit of

clergy."

In discussing catastrophes, the Duke indulges in statements, partly

scientific, partly anecdotic, which appear to me to be somewhat

misleading. We are told, to begin with, that Sir Charles Lyell's

doctrine respecting the proper mode of interpreting the facts of

geology (which is commonly called uniformitarianism) "does not hold

its head quite so high as it once did." That is great news indeed.

But is it true? All I can say is that I am aware of nothing that has

happened of late that can in any way justify it; and my opinion is,

that the body of Lyell's doctrine, as laid down in that great work,

"The Principles of Geology," whatever may have happened to its head,

is a chief and permanent constituent of the foundations of geological

science.

But this question cannot he advantageously discussed, unless we take

some pains to discriminate between the essential part of the

uniformitarian doctrine and its accessories; and it does not appear

that the Duke of Argyll has carried his studies of geological

philosophy so far as this point. For he defines uniformitarianism to

be the assumption of the "extreme slowness and perfect continuity of

all geological changes."

What "perfect continuity" may mean in this definition, I am by no

means sure; but I can only imagine that it signifies the absence of

any break in the course of natural order during the millions of years,

the lapse of which is recorded by geological phenomena.

Is the Duke of Argyll prepared to say that any geologist of authority,

at the present day, believes that there is the slightest evidence of

the occurrence of supernatural intervention, during the long ages of

which the monuments are preserved to us in the crust of the earth? And

if he is not, in what sense has this part of the uniformitarian

doctrine, as he defines it, lowered its pretensions to represent

scientific truth?

As to the "extreme slowness of all geological changes," it is simply a

popular error to regard that as, in any wise, a fundamental and

necessary dogma of uniformitarianism. It is extremely astonishing to

me that any one who has carefully studied Lyell's great work can have

so completely failed to appreciate its purport, which yet is "writ

large" on the very title-page: "The Principles of Geology, being an

attempt to explain the former changes of the earth's surface by

reference to causes now in operation." The essence of Lyell's doctrine

is here written so that those who run may read; and it has nothing to

do with the quickness or slowness of the past changes of the earth's

surface; except in so far as existing analogous changes may go on

slowly, and therefore create a presumption in favour of the slowness

of past changes.

With that epigrammatic force which characterises his style, Buffon

wrote, nearly a hundred and fifty years ago, in his famous "Théorie de

la Terre": "Pour juger de ce qui est arrivé, et même de ce qui

arrivera, nous n'avons qu'à examiner ce qui arrive." The key of the

past, as of the future, is to be sought in the present; and, only when

known causes of change have been shown to be insufficient, have we any

right to have recourse to unknown causes. Geology is as much a

historical science as archæology; and I apprehend that all sound

historical investigation rests upon this axiom. It underlay all

Hutton's work and animated Lyell and Scope in their successful efforts

to revolutionise the geology of half a century ago.

There is no antagonism whatever, and there never was, between the

belief in the views which had their chief and unwearied advocate in

Lyell and the belief in the occurrence of catastrophes. The first

edition of Lyell's "Principles," published in 1830, lies before me;

and a large part of the first volume is occupied by an account of

volcanic, seismic, and diluvial catastrophes which have occurred

within the historical period. Moreover, the author, over and over

again, expressly draws the attention of his readers to the consistency

of catastrophes with his doctrine.

Notwithstanding, therefore, that we have not witnessed

within the last three thousand years the devastation by

deluge of a large continent, yet, as we may predict the

future occurrence of such catastrophes, we are authorized to

regard them as part of the present order of nature, and they

may be introduced into geological speculations respecting

the past, provided that we do not imagine them to have been

more frequent or general than we expect them to be in time

to come (vol. i. p. 89).
