It is often maintained that what divides present-day political parties is a basic opposition in their ultimate philosophical commitments that cannot be settled by rational argument. The discussion of these antagonisms must therefore necessarily prove fruitless. Each side will remain unshaken in its conviction because the latter is based on a comprehensive world view that cannot be altered by any considerations proposed by the reason. The ultimate ends toward which men strive are diverse. Hence, it is altogether out of the question that men aiming at these diverse ends could agree on a uniform procedure.
Nothing is more absurd than this belief. Aside from the few consistent ascetics, who seek to divest life of all its external trappings and who finally succeed in attaining to a state of renunciation of all desire and action and, indeed, of self-annihilation, all men, however diverse may be their views on supernatural matters, agree in preferring a social system in which labor is more productive to one in which it is less productive. Even those who believe that an ever progressing improvement in the satisfaction of human wants does no good and that it would be better if we produced fewer material goods—though it is doubtful whether the number of those who are sincerely of this opinion is very large—would not wish that the same amount of labor should result in fewer goods. At most, they would wish that there should be less labor and consequently less production, but not that the same amount of labor should produce less.
The political antagonisms of today are not controversies over ultimate questions of philosophy, but opposing answers to the question how a goal that all acknowledge as legitimate can be achieved most quickly and with the least sacrifice. This goal, at which all men aim, is the best possible satisfaction of human wants; it is prosperity and abundance. Of course, this is not all that men aspire to, but it is all that they can expect to attain by resort to external means and by way of social cooperation. The inner blessings—happiness, peace of mind, exaltation—must be sought by each man within himself alone.
Liberalism is no religion, no world view, no party of special interests. It is no religion because it demands neither faith nor devotion, because there is nothing mystical about it, and because it has no dogmas. It is no world view because it does not try to explain the cosmos and because it says nothing and does not seek to say anything about the meaning and purpose of human existence. It is no party of special interests because it does not provide or seek to provide any special advantage whatsoever to any individual or any group. It is something entirely different. It is an ideology, a doctrine of the mutual relationship among the members of society and, at the same time, the application of this doctrine to the conduct of men in actual society. It promises nothing that exceeds what can be accomplished in society and through society. It seeks to give men only one thing, the peaceful, undisturbed development of material well-being for all, in order thereby to shield them from the external causes of pain and suffering as far as it lies within the power of social institutions to do so at all. To diminish suffering, to increase happiness: that is its aim.
No sect and no political party has believed that it could afford to forgo advancing its cause by appealing to men’s senses. Rhetorical bombast, music and song resound, banners wave, flowers and colors serve as symbols, and the leaders seek to attach their followers to their own person. Liberalism has nothing to do with all this. It has no party flower and no party color, no party song and no party idols, no symbols and no slogans. It has the substance and the arguments. These must lead it to victory.
