These laws, these institutions, these beliefs, handed down by inheritance or tradition, finally obscure or conceal their economic origin, and philosophers and jurists and often even the laity defend them as truths, subsisting by virtue of their own intrinsic merits, without seeing their real source, but the latter—the economic sub-stratum—is none the less the only scientific explanation of these laws, institutions and beliefs. And in this fact consists the greatness and strength of the perspicacious conception of the genius of Marx.[82]

As in the modern world there are now but two classes, with subordinate varieties,—on the one side the workers to whatever category they belong, and on the other the property owners who do not work,—the socialist theory of Marx leads us to this evident conclusion: since political parties are merely the echoes and the mouth-pieces of class interests—no matter what the subvarieties of these classes may be—there can be substantially only two political parties: the socialist labor party and the individualist party of the class in possession of the land and the other means of production.

The difference in the character of the economic monopoly may cause, it is true, a certain diversity of political color, and I have always contended that the great landed proprietors represent the conservative tendencies of political stagnation, while the holders of financial or industrial capital represent in many instances the progressive party, driven by its own nature to petty innovations of form, while finally those who possess only an intellectual capital, the liberal professions, etc., may go to the extreme length of political radicalism.

On the vital question—that is to say on the economic question of property—conservatives, progressives and radicals are all individualists. On this point they are all, in their essential nature of the same social class and, in spite of certain sentimental sympathies, the adversaries of the working class and of those who, although born on the other shore, have embraced the political programme of that class, a programme necessarily corresponding to the primordial economic necessity—that is to say, the socialization of the land and the means of production with all the innumerable and radical moral, juridical and political transformations, which this socialization will inevitably bring to pass in the social world.

This is why contemporary political life cannot but degenerate into the most sterile bysantinisme and the most corrupt strife for bribes and spoils, when it is confined to the superficial skirmishes between individualist parties, which differ only by a shade and in their formal names, but whose ideas are so similar that one often sees radicals and progressives less modern than many conservatives.

There will be a new birth of political life only with the development of the socialist party, because, after the disappearance from the political stage of the historical figures of the patriots (the founders of modern Italy) and of the personal reasons which split up the representatives into different political groups, the formation of one single individualist party will become necessary, as I declared in the Italian Chamber on the 20th of December, 1893.

The historical duel will then be begun, and the Class Struggle will then display on the field of politics all its beneficent influence. Beneficent, I say, because the class struggle must be understood not in the contemptible sense of a Saturnalia of fist-fights and outrages, of malevolence and personal violence, but must be worthily conceived as a great social drama. With all my heart I hope that this conflict may be settled, for the progress of civilization, without bloody convulsions, but historical destiny has decreed the conflict, and it is not given to us or to others to avert or postpone it.

It follows from all that we have just said that these ideas of political socialism, because they are scientific, dispose their partisans both to personal tolerance and to theoretical inflexibility.[83] This is also a conclusion reached by experimental psychology in the domain of philosophy. However great our personal sympathies may be for such or such a representative of the radical faction of the individualist party (as well as for every honorable and sincere representative of any scientific, religious or political opinion whatsoever), we are bound to recognize that there are on the side of socialism no partiti affini.[84] It is necessary to be on one side or the other—individualist or socialist. There is no middle ground. And I am constantly growing more and more convinced that the only serviceable tactics for the formation of a socialist party likely to live, is precisely that policy of theoretical inflexibility and of refusing to enter into any "alliance" with partiti affini, as such an alliance is for socialism only a "false placenta" for a fetus that is unlikely to live.

The conservative and the socialist are the natural products of the individual character and the social environment. One is born a conservative or an innovator just as one is born a painter or a surgeon. Therefore the socialists have no contempt for or bitterness toward the sincere representatives of any faction of the conservative party, though they combat their ideas unrelentingly. If such or such a socialist shows himself intolerant, if he abuses his opponents, this is because he is the victim of a passing emotion or of an ill-balanced temperament; it is, therefore, very excusable.

The thing that provokes a smile of pity is to see certain conservatives "young in years, but old in thought"—for conservatism in the young can be nothing but the effect of calculating selfishness or the index of psychical anemia—have an air of complacency or of pity for socialists whom they consider, at best, as "misled," without perceiving that what is normal is for the old to be conservatives, but that young conservatives can be nothing but egoists who are afraid of losing the life of idle luxury into which they were born or the advantages of the orthodox fashion of dividing (?) the fruits of labor. Their hearts at least, if not their brains, are abnormally small. The socialist, who has everything to lose and nothing to gain by boldly declaring his position and principles, possesses by contrast all the superiority of a disinterested altruism, especially when having been born in the aristocratic or the bourgeois class he has renounced the brilliant pleasure of a life of leisure to defend the cause of the weak and the oppressed.[85]
