Nationalism is not to be confused with patriotism.
Both words are normally used in so vague a way that any definition is liable to be challenged, but one must draw a distinction between them, since two different and even opposing ideas are involved. By “patriotism” I mean devotion to a particular place and a particular way of life, which one believes to be the best in the world but has no wish to force on other people. Patriotism is of its nature defensive, both militarily and culturally. Nationalism, on the other hand, is inseparable from the desire for power. The abiding purpose of every nationalist is to secure more power and more prestige, not for himself but for the nation or other unit in which he has chosen to sink his own individuality.
Nationalism, in the extended sense in which I am using the word, includes such movements and tendencies as Communism, political Catholicism, Zionism, Anti-Semitism, Trotskyism and Pacifism. It does not necessarily mean loyalty to a government or a country, still less to one’s own country, and it is not even strictly necessary that the units in which it deals should actually exist. To name a few obvious examples, Jewry, Islam, Christendom, the Proletariat and the White Race are all of them objects of passionate nationalistic feeling: but their existence can be seriously questioned, and there is no definition of any one of them that would be universally accepted.
The nationalist does not go on the principle of simply ganging up with the strongest side. On the contrary, having picked his side, he persuades himself that it is the strongest, and is able to stick to his belief even when the facts are overwhelmingly against him. Nationalism is power-hunger tempered by self-deception. Every nationalist is capable of the most flagrant dishonesty, but he is also — since he is conscious of serving something bigger than himself — unshakably certain of being in the right
OBSESSION. As nearly as possible, no nationalist ever thinks, talks, or writes about anything except the superiority of his own power unit. It is difficult if not impossible for any nationalist to conceal his allegiance. The smallest slur upon his own unit, or any implied praise of a rival organization, fills him with uneasiness, which he can relieve only by making some sharp retort. If the chosen unit is an actual country, such as Ireland or India, he will generally claim superiority for it not only in military power and political virtue, but in art, literature, sport, structure of the language, the physical beauty of the inhabitants, and perhaps even in climate, scenery and cooking. He will show great sensitiveness about such things as the correct display of flags, relative size of headlines and the order in which different countries are named. Nomenclature plays a very important part in nationalist thought. Countries which have won their independence or gone through a nationalist revolution usually change their names, and any country or other unit round which strong feelings revolve is likely to have several names, each of them carrying a different implication. The two sides of the Spanish Civil War had between them nine or ten names expressing different degrees of love and hatred. Some of these names (e.g. “Patriots” for Franco-supporters, or “Loyalists” for Government-supporters) were frankly question begging, and there was no single one of the two rival factions could have agreed to use.
