In the case of the chartered accountant, or the stockbroker, or the pedlar, this special knowledge is not so damning a thing. No accountant, be he ever so limited, can be wholly contented with accountancy as an explanation or sum-total of life; nor can the broker, however absorbed in his business, admit to his friends that the manipulating of stocks and shares is the only matter which should consume the interest of mortals. It is otherwise with the politician, the priest, the man of letters, the professional philosopher, and even the lawyer and the soldier. There is nothing human which may not enter into politics, religion or philosophy, or become the subject of literature; the human complexion of the State may be transformed by the professional prejudice of the lawyer or the soldier.
Consider how, for democratic purposes, the Member of Parliament is made. There is no need to pay undue attention to the amusing exaggerations and distortions of Mr. Belloc and Mr. Cecil Chesterton. The Member of Parliament has been supported in his constituency by a group of local politicals who have a healthy enthusiasm for the party war-cry. The serious candidate is too experienced, too professional, to share those enthusiasms in precisely that form which they assume, at election time, in the minds of his supporters. I do not mean that he is less enthusiastic than they, a less whole-hearted backer of his party, but that, from the nature of his political experience, politics presents itself to him under a perspective which cannot be theirs. He leaves his constituency a specially ordained champion of political truth; he arrives at Westminster a unit in the crowd.
If we follow our member to Westminster we shall soon find that he has fallen into the Parliamentary manner; that his ideas are grouped around the ideas familiar to the House of Commons; that he has taken its tone, and that his habits are becoming gradually assimilated to the habits of those few with whom he especially associates himself. Let us attend a meeting of some propagandist committee comprising a number of expert politicians—Members of Parliament, or others. We shall find there the bond of a common knowledge, a common sympathy, a common approach towards a given subject, a common jargon. We shall be aware of the fact that we have come into a particular, highly-specialised atmosphere, where the familiar language of ordinary life, the familiar ideas, would be intrusions, meriting nothing but frowns or compassionate smiles.
And the same thing is true of most corporate journalism and most corporate religion. The atmosphere is highly specialised; it is binding; and those who live in it believe it to be co-extensive with the whole of life. Let us bind ourselves by Tolstoy; let us agree to loosen ourselves by Nietzsche; but, in any case let us agree to love our neighbour on the principle of a close corporation. The main influences which shape the modern world operate, for the most part, through intellectual groups; each group can only be appealed to in a language familiar to it; it can only act on principles (consciously accepted or presupposed) which are its very special property; you can never touch it to the quick, in its corporate and active capacity, without accepting or appearing to accept its collective prejudices. Its differentia is that which separates it from the unit of common humanity.
Thus we come to something more difficult to analyse than specialisation of work—a specialisation of sentiment, habits and morals, which makes people supremely sapient within a narrow sphere which they have appropriated, and so limited as to be blind in the broad field of ethics which lies outside their special ken. And yet it is through these groups, keen-eyed in one direction, blind in others, that the intellect, the reforming zeal, the earnestness, the idealism of the age, have to pass before ideas and vague aspiration can be transformed into action or effective influence. These groups are the main-drainage-system of modern life; they are the ordinary channels through which the business of the world has to pass, and its organised thought be directed. Take any one of these groups, and consider its differential character, its mode of apperception, its êthos, and you find it something deformed, twisted, strained in one direction, like a tree by the sea-shore. But take a few score of them, and imagine their qualities fused together, and the result would accord with the ideals of common humanity—ideals vaguely conceived, perhaps, but generous. It is just because the qualities of these groups, in politics, religion, social work, and to a lesser extent in literature, are not and cannot be fused together, but on the contrary, stand apart in water-tight compartments, so that the whole is like an elaborate system of checks to make each part inoperative, that, at a time when the whole community is strangely alive with good will, the actual social achievement is beyond measure disappointing.
The test of success or failure is the degree of satisfaction afforded to the common man. By the "common man" I do not mean the inferior man, but the man who has not specialised himself out of his common humanity. If there is any interest which an honest lawyer can share with an honest fisherman, a decent cockney with a decent Bedouin Arab, he does it in virtue of this nobler "commonness;" it may include the interests of good fellowship, of delight in song or nature, of a belief in God, and a host of indescribable interests which do not belong to the mechanism and compulsory organisation of life; it includes some "dram of folly," some capacity for "laughable blunder" in intercourse between men. Culture may break in upon this "commonness" and destroy it. But it need not be so. Shakespeare has this commonness in a high degree; so have Johnson, and Goldsmith, and Lamb; all great artists have had it when their culture has not crazed them, or when they have not lifted themselves into an almost mystical absorption in exercising some gift of austere, monumental expression; in which case, like Milton, they scarcely belong to the category of humans; their food is ambrosial, and their wine is nectar.
The task of the inspired politician has become harder in proportion as the problem of government has become more intricate and more specialised. He must work through his machinery, which includes not only the administrative machine, but all those groups, in and out of Parliament, limited by their ethical and sentimental specialities. He must be professional enough to appreciate the ground of their excellences, and "common" enough to discard their limitations. It is only when there are several such men, powerful enough to leaven politics and lead politicians, that modern democracy can have any shadow of reality—men who understand the rank and file of humanity, conversant also with the complicated machine and the contending groups of narrowly defined ideals, men fired with that constructive imagination which crystallises in common sense.
