The all-dominant influence of the idea of the nation, I insist, is not a theory or a speculative suggestion, it is a literal and obvious fact. Let every other one of the favouring conditions of nationality, the geographical, historical, economic be realised by a population; yet, if that population has no collective self-consciousness, is not strongly actuated to collective volition by the group spirit, it will remain not a nation, but a mere aggregate of individuals, having more or less organic unity due to the differentiation and interdependence of its parts, but lacking that higher bond of unity which alone can ensure its stability and continuity, and which, especially, can alone enable it to withstand and survive the peaceful pressure or the warlike impact of true nations. I am not at present defending nationality; I shall come back to the question of its value. I am now only concerned with the psychological problem of the nature and conditions of the development of national self-consciousness. I have been using the latter phrase and the phrase ‘the idea of the nation’ as a shorthand expression; but I must remind the reader that we have to beware of the intellectualist error of regarding ideas as moving powers; ideas as merely intellectual representations or conceptions have no motive power, they are in themselves indifferent. It is only in so far as the object conceived becomes the object of some sentiment that the conception of it moves us strongly to feeling and action. I must refer, therefore, to what I have written on the sentiments and the self-regarding sentiment[89]. Here I would insist on the strictness in this point of our analogy between the individual and the national mind. I have pointed out that the individual’s idea of himself only develops beyond a rudimentary stage in virtue of and in so far as this idea becomes the nucleus of a strong self-regarding sentiment which gives him an interest in himself, directs his attention upon his own personality and its relations, and impels him to strive to know himself. So that a developed individual self-consciousness never is and never can be a purely intellectual growth, but always involves a strong sentiment, a centering of emotional conative tendencies upon this object, the self. Exactly the same is true of nations.
