Huxley, in a discourse at the opening of Sir Josiah Mason's College at Birmingham, laying hold of this phrase, expanded it by quoting some more words of mine, which are these: The civilized world is to be regarded as now being, for intellectual purposes, one great confederation, bound to a joint action and working to a common result; and whose members have for their proper outfit a knowledge of Greek, Roman, and Eastern antiquity, and of one another. Special local and temporary advantages being put out of account, that modern nation will in the intellectual and spiritual sphere make most progress which most thoroughly carries out this program."

Now on my phrase, thus enlarged, Professor Huxley remarks that when I speak of the above-mentioned knowledge as enabling us to know ourselves and the world, I assert literature to contain the materials which suffice for thus making us know ourselves and the world. But it is not by any means clear, says he, that after having learned all which ancient and modern literatures have to tell us, we have laid a sufficiently broad and deep foundation for that criticism of life, that knowledge of ourselves and the world, which constitutes culture. On the contrary, Professor Huxley declares that he finds himself "wholly unable to admit that either nations or individuals will really advance, if their outfit draws nothing from the stores of physical science. An army without weapons of precision, and with no particular base of operations might more hopefully enter upon a campaign on the Rhine, than a man, devoid of knowledge of what physical science has done in the last century, upon a criticism of life."

This shows how needful it is for those who are to discuss any matter together, to have a common understanding as to the sense of the terms they employ,-how needful, and how difficult. What Professor Huxley says, implies just the reproach which is so often brought against the

study of belles lettres, as they are called: that the study is an elegant one, but slight and ineffectual; a smattering of Greek and Latin and other ornamental things, of little use for any one whose object is to get at truth, and to be a practical man. So, too, M. Renan talks of the " superficial humanism" of a school course which treats us as if we were all going to be poets, writers, preachers, orators, and he opposes this humanism to positive science, or the critical search after truth. And there is always a tendency in those who are remonstrating against the predominance of letters in education, to understand by letters belles lettres, and by belles lettres a superficial humanism, the opposite of science or true knowledge.

But when we talk of knowing Greek and Roman antiquity, for instance, which is the knowledge people have called the humanities, I for my part mean a knowledge which is something more than a superficial humanism, mainly decorative. "I call all teaching scientific," says Wolf, the critic of Homer, "which is systematically laid out and followed up to its original sources. For example: a knowledge of classical antiquity is scientific when the remains of classical antiquity are correctly studied in the original languages." There can be no doubt that Wolf is perfectly right; that all learning is scientific which is systematically laid out and followed up to its original sources, and that a genuine humanism is scientific.

When I speak of knowing Greek and Roman antiquity, therefore, as a help to knowing ourselves and the world, I mean more than a knowledge of so much vocabulary, so much grammar, so many portions of authors in the Greek and Latin languages; I mean knowing the Greeks and Romans, and their life and genius, and what they were and Idid in the world; what we get from them, and what is its value. That, at least, is the ideal; and when we talk of endeavoring to know Greek and Roman antiquity, as a

help to knowing ourselves and the world, we mean endeavoring so to know them as to satisfy this ideal, however much we may still fall short of it.

The same also as to knowing our own and other modern nations, with the like aim of getting to understand ourselves and the world. To know the best that has been thought and said by the modern nations, is to know, says Professor Huxley, "only what modern literatures have to tell us; it is the criticism of life contained in modern literature." And yet "the distinctive character of our times," he urges, "lies in the vast and constantly increasing part which is played by natural knowledge." And how, therefore, can a man, devoid of knowledge of what physical science has done in the last century, enter hopefully upon a criticism of modern life?

Let us, I say, be agreed about the meaning of the terms we are using. I talk of knowing the best which has been thought and uttered in the world; Professor Huxley says this means knowing Literature. Literature is a large word; it may mean everything written with letters or printed in a book. Euclid's Elements and Newton's Principia are thus literature. All knowledge that reaches us through books is literature. But by literature Professor Huxley means belles lettres. He means to make me say, that knowing the best which has been thought and said by the modern nations is knowing their belles lettres and no more. And this is no sufficient equipment, he argues, for a criticism of modern life. But as I do not mean, by knowing ancient Rome, knowing merely more or less of Latin belles lettres, and taking no account of Rome's military, and political, and legal, and administrative work in the world; and as, by knowing ancient Greece, I understand knowing her as the giver of Greek art, and the guide to a free and right use of reason and to scientific method, and the founder of our mathematics and physics and astronomy and biology,

I understand knowing her as all this, and not merely knowing certain Greek poems, and histories, and treatises, and speeches, so as to the knowledge of modern nations also. By knowing modern nations, I mean not merely knowing their belles lettres, but knowing also what has been done by such men as Copernicus, Galileo, Newton, Darwin. "Our ancestors learned," says Professor Huxley, "that the earth is the center of the visible universe, and that man is the cynosure of things terrestrial; and more especially was it inculcated that the course of nature has no fixed order, but that it could be, and constantly was, altered." But for us now, continues Professor Huxley, "the notions of the beginning and the end of the world entertained by our forefathers are no longer credible. It is very certain that the earth is not the chief body in the material universe, and that the world is not subordinated to man's use. It is even more certain that nature is the expression of a definite order, with which nothing interferes." "And yet," he cries, "the purely classical education advocated by the representatives of the humanists in our day gives no inkling of all this!"

In due place and time I will just touch upon that vexed question of classical education; but at present the question is as to what is meant by knowing the best which modern nations have thought and said. It is not knowing their belles lettres merely which is meant. To know Italian belles lettres is not to know Italy, and to know English belles lettres is not to know England. Into knowing Italy and England there comes a great deal more, Galileo and Newton amongst it. The reproach of being a superficial humanism, a tincture of belles lettres, may attach rightly enough to some other disciplines; but to the particular discipline recommended when I proposed knowing the best that has been thought and said in the world, it does not apply. In that best I certainly include what in modern times has

been thought and said by the great observers and knowers of nature.

5. PROOF AND EVIDENCE

Having determined upon the proposition and made clear the precise point or points at issue, the argumentative writer must next turn his attention to the question of proof. To prove a proposition, something must be brought forward to substantiate it, to show that there is ground for believing it true. Anything so brought forward, that is, anything used to induce belief in the truth of a proposition, is called evidence, or, in some cases, an argument. The whole body of evidence used to establish the truth of the proposition is called the proof.

The beginner should note here that mere assertion on his part does not constitute proof. No statement that he may make in support of his proposition can be regarded as evidence of its truth unless that statement is in itself a fact or truth generally accepted, or unless it is, in its turn, supported by other facts or truths about which there is no dispute. Every statement made in support of the proposition, therefore, must be backed up by unimpeachable evidence. The only way to prove a proposition, in short, is to bring forward arguments in its favor which every one admits to be sound.

As so much depends in argumentation upon the soundness of the arguments used, some knowledge of the nature and kinds of evidence will be found helpful by every disputant. Evidence, as we have already defined it, is anything used to induce belief in the
