At the other end of the scale, we have the philosophical conservatism of such a thinker as Edmund Burke, which is keenly aware of the organic unity of society and looks constantly to the good of the whole, deriving from that consideration its leading motives and principles, and which trusts principally to the growth of the group spirit for the holding of the balance between conflicting interests and for the promotion of the public welfare.
Having seen the importance for national life of the idea of the nation, the diffusion of which through the minds of the people constitutes national self-consciousness, let us glance for a moment at the way other ideas may play leading rôles in national life. Such are ideas which became national ideals, that is to say, ideas of some end to be realised by the nation which became widely entertained and the objects of strong sentiments and of collective emotion and desire and which, therefore, determine collective action.
I shall not attempt to deal separately with various classes of such ideas, or ideals--the political, the religious, the economic; but shall only note the fact that they have played and may yet play great parts in the history of the world.
Men are not swayed exclusively by considerations of material self-interest, as the older school of economists generally assumed; nor even by spiritual self-interest, as too much of the religious teaching of the past has assumed; nor even by consideration of the welfare of the social groups of which they are members. Many of the great events of history have been determined by ideas that have had no relation to individual welfare, but have inspired a collective enthusiasm for collective action, for national effort, of a disinterested kind; and the lives of some nations have been dominated by some one or two such ideas. These ideas are first conceived and taught by some great man, or by a few men who have acquired prestige and influence; they then become generally accepted by suggestion and imitation, accepted more or less uncritically and established beyond the reach of argument and reasoning.
No matter what the character of the idea, its collective acceptance by a people enhances for the time the homogeneity of mind among them, renders the people more intimately a unity, and serves also to mark it off more sharply from other peoples among whom other ideas prevail.
