During those fifteen years at least two-thirds of the population,

probably seven or eight millions of people, died by violence or by

starvation. Then the English came in; put an end to the independence

and self-government which had wrought this hideous evil; restored

order, kept the peace, and gave to each individual a liberty which,

during the evil days of their own self-government, not one human being

possessed, save only the blood-stained tyrant who at the moment was

ruler. I stopped at village after village in the Sudan, and in many of

them I was struck by the fact that, while there were plenty of

children, they were all under twelve years old; and inquiry always

developed that these children were known as "Government children,"

because in the days of Mahdism it was the literal truth that in a very

large proportion of the communities every child was either killed or

died of starvation and hardship, whereas under the peace brought by

English rule families are flourishing, men and women are no longer

hunted to death, and the children are brought up under more favorable

circumstances, for soul and body, than have ever previously obtained

in the entire history of the Sudan. In administration, in education,

in police work, the Sirdar[12] and his lieutenants, great and small,

have performed to perfection a task equally important and difficult.

The Government officials, civil and military, who are responsible for

this task, and the Egyptian and Sudanese who have worked with and

under them, and as directed by them, have a claim upon all civilized

mankind which should be heartily admitted. It would be a crime not to

go on with the work, a work which the inhabitants themselves are

helpless to perform, unless under firm and wise guidance from outside.

I have met people who had some doubt as to whether the Sudan would

pay. Personally, I think it probably will. But I may add that, in my

judgment, this fact does not alter the duty of England to stay there.

It is not worth while belonging to a big nation unless the big nation

is willing when the necessity arises to undertake a big task. I feel

about you in the Sudan just as I felt about us in Panama. When we

acquired the right to build the Panama Canal, and entered on the task,

there were worthy people who came to me and said they wondered whether

it would pay. I always answered that it was one of the great world

works which had to be done; that it was our business as a nation to do

it, if we were ready to make good our claim to be treated as a great

world Power; and that as we were unwilling to abandon the claim, no

American worth his salt ought to hesitate about performing the task. I

feel just the same way about you in the Sudan.

[12] Sir Reginald Wingate, who at the time of this address was

both Sirdar of the Anglo-Egyptian Army and Governor-General of the

Sudan.--L.F.A.

Now as to Egypt. It would not be worth my while to speak to you at

all, nor would it be worth your while to listen, unless on condition

that I say what I deeply feel ought to be said. I speak as an

outsider, but in one way this is an advantage, for I speak without

national prejudice. I would not talk to you about your own internal

affairs here at home; but you are so very busy at home that I am not

sure whether you realize just how things are, in some places at least,

abroad. At any rate, it can do you no harm to hear the view of one who

has actually been on the ground, and has information at first hand; of

one, moreover, who, it is true, is a sincere well-wisher of the

British Empire, but who is not English by blood, and who is impelled

to speak mainly because of his deep concern in the welfare of mankind

and in the future of civilization. Remember also that I who address

you am not only an American, but a Radical, a real--not a

mock--democrat, and that what I have to say is spoken chiefly because

I am a democrat, a man who feels that his first thought is bound to be

the welfare of the masses of mankind, and his first duty to war

against violence and injustice and wrong-doing, wherever found; and I

advise you only in accordance with the principles on which I have

myself acted as American President in dealing with the Philippines.

In Egypt you are not only the guardians of your own interests; you are

also the guardians of the interests of civilization; and the present

condition of affairs in Egypt is a grave menace to both your Empire

and the entire civilized world. You have given Egypt the best

government it has had for at least two thousand years--probably a

better government than it has ever had before; for never in history

has the poor man in Egypt, the tiller of the soil, the ordinary

laborer, been treated with as much justice and mercy, under a rule as

free from corruption and brutality, as during the last twenty-eight

years. Yet recent events, and especially what has happened in

connection with and following on the assassination of Boutros Pasha

three months ago, have shown that, in certain vital points, you have

erred; and it is for you to make good your error. It has been an error

proceeding from the effort to do too much and not too little in the

interests of the Egyptians themselves; but unfortunately it is

necessary for all of us who have to do with uncivilized peoples, and

especially with fanatical peoples, to remember that in such a

situation as yours in Egypt weakness, timidity, and sentimentality may

cause even more far-reaching harm than violence and injustice. Of all

broken reeds, sentimentality[13] is the most broken reed on which

righteousness can lean.

[13] In the Introduction will be found Mr. Roosevelt's

differentiation of sentimentality from sentiment.--L.F.A.

In Egypt you have been treating all religions with studied fairness

and impartiality; and instead of gratefully acknowledging this, a

noisy section of the native population takes advantage of what your

good treatment has done to bring about an anti-foreign movement, a

movement in which, as events have shown, murder on a large or a small

scale is expected to play a leading part. Boutros Pasha[14] was the

best and most competent Egyptian official, a steadfast upholder of

English rule, and an earnest worker for the welfare of his countrymen;

and he was murdered simply and solely because of these facts, and

because he did his duty wisely, fearlessly, and uprightly. The

attitude of the so-called Egyptian Nationalist Party in connection

with this murder has shown that they were neither desirous nor capable

of guaranteeing even that primary justice the failure to supply which

makes self-government not merely an empty but a noxious farce. Such

are the conditions; and where the effort made by your officials to

help the Egyptians towards self-government is taken advantage of by

them, not to make things better, not to help their country, but to try

to bring murderous chaos upon the land, then it becomes the primary

duty of whoever is responsible for the government in Egypt to

establish order, and to take whatever measures are necessary to that

end.

[14] Compare the address at the University of Cairo.--L.F.A.

It was with this primary object of establishing order that you went

into Egypt twenty-eight years ago; and the chief and ample

justification for your presence in Egypt was this absolute necessity

of order being established from without, coupled with your ability and

willingness to establish it. Now, either you have the right to be in

Egypt or you have not; either it is or it is not your duty to

establish and keep order. If you feel that you have not the right to

be in Egypt, if you do not wish to establish and to keep order there,

why, then, by all means get out of Egypt. If, as I hope, you feel that

your duty to civilized mankind and your fealty to your own great

traditions alike bid you to stay, then make the fact and the name

agree and show that you are ready to meet in very deed the

responsibility which is yours. It is the thing, not the form, which is

vital; if the present forms of government in Egypt, established by you

in the hope that they would help the Egyptians upward, merely serve to

provoke and permit disorder, then it is for you to alter the forms;

for if you stay in Egypt it is your first duty to keep order, and

above all things also to punish murder and to bring to justice all who

directly or indirectly incite others to commit murder or condone the

crime when it is committed. When a people treats assassination as the

corner-stone of self-government, it forfeits all right to be treated

as worthy of self-government. You are in Egypt for several purposes,

and among them one of the greatest is the benefit of the Egyptian

people. You saved them from ruin by coming in, and at the present

moment, if they are not governed from outside, they will again sink

into a welter of chaos. Some nation must govern Egypt. I hope and

believe that you will decide that it is your duty to be that nation.

BIOLOGICAL ANALOGIES IN HISTORY[15]

[15] The text of this Lecture, which is the Romanes Lecture for

1910, is included in the present volume under the courteous

permission of the Vice-Chancellor of the University of

Oxford.--L.F.A.

Delivered at Oxford, June 7, 1910

An American who in response to such an invitation as I have received

speaks in this University of ancient renown, cannot but feel with

peculiar vividness the interest and charm of his surroundings, fraught

as they are with a thousand associations. Your great universities, and

all the memories that make them great, are living realities in the

minds of scores of thousands of men who have never seen them and who

dwell across the seas in other lands. Moreover, these associations are

no stronger in the men of English stock than in those who are not. My

people have been for eight generations in America; but in one thing I

am like the Americans of to-morrow, rather than like many of the

Americans of to-day; for I have in my veins the blood of men who came

from many different European races. The ethnic make-up of our people

is slowly changing, so that constantly the race tends to become more

and more akin to that of those Americans who like myself are of the

old stock but not mainly of English stock. Yet I think that as time

goes by, mutual respect, understanding, and sympathy among the

English-speaking peoples grow greater and not less. Any of my

ancestors, Hollander or Huguenot, Scotchman or Irishman, who had come

to Oxford in "the spacious days of great Elizabeth," would have felt

far more alien than I, their descendant, now feel. Common heirship in

the things of the spirit makes a closer bond than common heirship in

the things of the body.

More than ever before in the world's history we of to-day seek to

penetrate the causes of the mysteries that surround not only mankind

but all life, both in the present and the past. We search, we peer, we

see things dimly; here and there we get a ray of clear vision, as we

look before and after. We study the tremendous procession of the ages,

from the immemorial past when in "cramp elf and saurian forms" the

creative forces "swathed their too-much power," down to the yesterday,

a few score thousand years distant only, when the history of man

became the overwhelming fact in the history of life on this planet;

and studying, we see strange analogies in the phenomena of life and

death, of birth, growth, and change, between those physical groups of

animal life which we designate as species, forms, races, and the

highly complex and composite entities which rise before our minds when

we speak of nations and civilizations.

It is this study which has given science its present-day prominence.

In the world of intellect, doubtless, the most marked features in the

history of the past century have been the extraordinary advances in

scientific knowledge and investigation, and in the position held by

the men of science with reference to those engaged in other pursuits.

I am not now speaking of applied science; of the science, for

instance, which, having revolutionized transportation on the earth and

the water, is now on the brink of carrying it into the air; of the

science that finds its expression in such extraordinary achievements

as the telephone and the telegraph; of the sciences which have so

accelerated the velocity of movement in social and industrial

conditions--for the changes in the mechanical appliances of ordinary

life during the last three generations have been greater than in all

the preceding generations since history dawned. I speak of the science

which has no more direct bearing upon the affairs of our everyday life

than literature or music, painting or sculpture, poetry or history. A

hundred years ago the ordinary man of cultivation had to know

something of these last subjects; but the probabilities were rather

against his having any but the most superficial scientific knowledge.

At present all this has changed, thanks to the interest taken in

scientific discoveries, the large circulation of scientific books, and

the rapidity with which ideas originating among students of the most

advanced and abstruse sciences become, at least partially, domiciled

in the popular mind.

Another feature of the change, of the growth in the position of

science in the eyes of every one, and of the greatly increased respect

naturally resulting for scientific methods, has been a certain

tendency for scientific students to encroach on other fields. This is

particularly true of the field of historical study. Not only have

scientific men insisted upon the necessity of considering the history

of man, especially in its early stages, in connection with what

biology shows to be the history of life, but furthermore there has

arisen a demand that history shall itself be treated as a science.

Both positions are in their essence right; but as regards each

position the more arrogant among the invaders of the new realm of

knowledge take an attitude to which it is not necessary to assent. As

regards the latter of the two positions, that which would treat

history henceforth merely as one branch of scientific study, we must

of course cordially agree that accuracy in recording facts and

appreciation of their relative worth and inter-relationship are just

as necessary in historical study as in any other kind of study. The

fact that a book, though interesting, is untrue, of course removes it

at once from the category of history, however much it may still

deserve to retain a place in the always desirable group of volumes

which deal with entertaining fiction. But the converse also holds, at

least to the extent of permitting us to insist upon what would seem to

be the elementary fact that a book which is written to be read should

be readable. This rather obvious truth seems to have been forgotten by

some of the more zealous scientific historians, who apparently hold

that the worth of a historical book is directly in proportion to the

impossibility of reading it, save as a painful duty. Now I am willing

that history shall be treated as a branch of science, but only on

condition that it also remains a branch of literature; and,

furthermore, I believe that as the field of science encroaches on the

field of literature there should be a corresponding encroachment of

literature upon science; and I hold that one of the great needs, which

can only be met by very able men whose culture is broad enough to

include literature as well as science, is the need of books for

scientific laymen. We need a literature of science which shall be

readable. So far from doing away with the school of great historians,

the school of Polybius and Tacitus, Gibbon and Macaulay, we need

merely that the future writers of history, without losing the

qualities which have made these men great, shall also utilize the new

facts and new methods which science has put at their disposal. Dryness

is not in itself a measure of value. No "scientific" treatise about

St. Louis will displace Joinville, for the very reason that

Joinville's place is in both history and literature; no minute study

of the Napoleonic wars will teach us more than Marbot--and Marbot is

as interesting as Walter Scott. Moreover, certain at least of the

branches of science should likewise be treated by masters in the art

of presentment, so that the layman interested in science, no less than

the layman interested in history, shall have on his shelves classics

which can be read. Whether this wish be or be not capable of

realization, it assuredly remains true that the great historian of the

future must essentially represent the ideal striven after by the great

historians of the past. The industrious collector of facts occupies an

honorable, but not an exalted, position, and the scientific historian

who produces books which are not literature must rest content with the

honor, substantial, but not of the highest type, that belongs to him

who gathers material which some time some great master shall arise to

use.

Yet, while freely conceding all that can be said of the masters of

literature, we must insist upon the historian of mankind working in

the scientific spirit, and using the treasure-houses of science. He

who would fully treat of man must know at least something of biology,

of the science that treats of living, breathing things; and

especially of that science of evolution which is inseparably connected

with the great name of Darwin. Of course there is no exact parallelism

between the birth, growth, and death of species in the animal world,

and the birth, growth, and death of societies in the world of man. Yet

there is a certain parallelism. There are strange analogies; it may be

that there are homologies.

How far the resemblances between the two sets of phenomena are more

than accidental, how far biology can be used as an aid in the

interpretation of human history, we cannot at present say. The

historian should never forget, what the highest type of scientific man

is always teaching us to remember, that willingness to admit ignorance

is a prime factor in developing wisdom out of knowledge. Wisdom is

advanced by research which enables us to add to knowledge; and,

moreover, the way for wisdom is made ready when men who record facts

of vast but unknown import, if asked to explain their full

significance, are willing frankly to answer that they do not know. The

research which enables us to add to the sum of complete knowledge

stands first; but second only stands the research which, while

enabling us clearly to pose the problem, also requires us to say that

with our present knowledge we can offer no complete solution.

Let me illustrate what I mean by an instance or two taken from one of

the most fascinating branches of world-history, the history of the

higher forms of life, of mammalian life, on this globe.

Geologists and astronomers are not agreed as to the length of time

necessary for the changes that have taken place. At any rate, many

hundreds of thousands of years, some millions of years, have passed by

since in the eocene, at the beginning of the tertiary period, we find

the traces of an abundant, varied, and highly developed mammalian life

on the land masses out of which have grown the continents as we see

them to-day. The ages swept by, until, with the advent of man

substantially in the physical shape in which we now know him, we also

find a mammalian fauna not essentially different in kind, though

widely differing in distribution, from that of the present day.

Throughout this immense period form succeeds form, type succeeds type,

in obedience to laws of evolution, of progress and retrogression, of

development and death, which we as yet understand only in the most

imperfect manner. As knowledge increases our wisdom is often turned

into foolishness, and many of the phenomena of evolution which seemed

clearly explicable to the learned master of science who founded these

lectures, to us nowadays seem far less satisfactorily explained. The

scientific men of most note now differ widely in their estimates of

the relative parts played in evolution by natural selection, by

mutation, by the inheritance of acquired characteristics; and we study

their writings with a growing impression that there are forces at work

which our blinded eyes wholly fail to apprehend; and where this is the

case the part of wisdom is to say that we believe we have such and

such partial explanations, but that we are not warranted in saying

that we have the whole explanation. In tracing the history of the

development of faunal life during this period, the age of mammals,

there are some facts which are clearly established, some great and

sweeping changes for which we can with certainty ascribe reasons.

There are other facts as to which we grope in the dark, and vast

changes, vast catastrophes, of which we can give no adequate

explanation.

Before illustrating these types, let us settle one or two matters of

terminology. In the changes, the development and extinction, of species

we must remember that such expressions as "a new species," or as "a

species becoming extinct," are each commonly and indiscriminately

used to express totally different and opposite meanings. Of course

the "new" species is not new in the sense that its ancestors

appeared later on the globe's surface than those of any old

species tottering to extinction. Phylogenetically, each animal now

living must necessarily trace its ancestral descent back through

countless generations, through æons of time, to the early stages of

the appearance of life on the globe. All that we mean by a "new"

species is that from some cause, or set of causes, one of these

ancestral stems slowly or suddenly develops into a form unlike any

that has preceded it; so that while in one form of life the ancestral

type is continuously repeated and the old species continues to exist,

in another form of life there is a deviation from the ancestral type

and a new species appears.

Similarly, "extinction of species" is a term which has two entirely

different meanings. The type may become extinct by dying out and

leaving no descendants. Or it may die out because as the generations

go by there is change, slow or swift, until a new form is produced.

Thus in one case the line of life comes to an end. In the other case

it changes into something different. The huge titanothere, and the

small three-toed horse, both existed at what may roughly be called the

same period of the world's history, back in the middle of the

mammalian age. Both are extinct in the sense that each has completely

disappeared and that nothing like either is to be found in the world

to-day. But whereas all the individual titanotheres finally died out,

leaving no descendants, a number of the three-toed horses did leave

descendants, and these descendants, constantly changing as the ages

went by, finally developed into the highly specialized one-toed

horses, asses, and zebras of to-day.

The analogy between the facts thus indicated and certain facts in the

development of human societies is striking. A further analogy is

supplied by a very curious tendency often visible in cases of intense

and extreme specialization. When an animal form becomes highly

specialized, the type at first, because of its specialization,

triumphs over its allied rivals and its enemies, and attains a great

development; until in many cases the specialization becomes so

extreme that from some cause unknown to us, or at which we merely

guess, it disappears. The new species which mark a new era commonly

come from the less specialized types, the less distinctive, dominant,

and striking types, of the preceding era.

When dealing with the changes, cataclysmic or gradual, which divide

one period of palæontological history from another, we can sometimes

assign causes, and again we cannot even guess at them. In the case of

single species, or of faunas of very restricted localities, the

explanation is often self-evident. A comparatively slight change in

the amount of moisture in the climate, with the attendant change in

vegetation, might readily mean the destruction of a group of huge

herbivores with a bodily size such that they needed a vast quantity of

food, and with teeth so weak or so peculiar that but one or two kinds

of plants could furnish this food. Again, we now know that the most

deadly foes of the higher forms of life are various lower forms of

life, such as insects, or microscopic creatures conveyed into the

blood by insects. There are districts in South America where many

large animals, wild and domestic, cannot live because of the presence

either of certain ticks or of certain baleful flies. In Africa there

is a terrible genus of poison fly, each species acting as the host of

microscopic creatures which are deadly to certain of the higher

vertebrates. One of these species, though harmless to man, is fatal to

all domestic animals, and this although harmless to the

closely-related wild kinsfolk of these animals. Another is fatal to

man himself, being the cause of the "sleeping sickness" which in many

large districts has killed out the entire population. Of course the

development or the extension of the range of any such insects, and any

one of many other causes which we see actually at work around us,

would readily account for the destruction of some given species or

even for the destruction of several species in a limited area of

country.

When whole faunal groups die out over large areas, the question is

different, and may or may not be susceptible of explanation with the

knowledge we actually possess. In the old arctogæal continent, for

instance, in what is now Europe, Asia, and North America, the glacial

period made a complete, but of course explicable, change in the faunal

life of the region. At one time the continent held a rich and varied

fauna. Then a period of great cold supervened, and a different fauna

succeeded the first. The explanation of the change is obvious.

But in many other cases we cannot so much as hazard a guess at why a

given change occurred. One of the most striking instances of these

inexplicable changes is that afforded by the history of South America

towards the close of the tertiary period. For ages South America had

been an island by itself, cut off from North America at the very time

that the latter was at least occasionally in land communication with

Asia. During this time a very peculiar fauna grew up in South America,

some of the types resembling nothing now existing, while others are

recognizable as ancestral forms of the ant-eaters, sloths, and

armadillos of to-day. It was a peculiar and diversified mammalian

fauna, of, on the whole, rather small species, and without any

representatives of the animals with which man has been most familiar

during his career on this earth.
