[70] It is this lack of even elementary knowledge of geology, biology, etc., which makes the vague ideal of anarchy so attractive to many men or the people with really bright minds, but with no scientific training, even though they repudiate the employment of violent methods. In my opinion a more wide-spread instruction in the natural sciences--together with their substitution for the classics--would do more than any repressive laws to suppress the outrages of anarchy.

[72] At the moment when I was correcting the proofs of the Italian edition of this book, the emotion had not yet subsided which grew out of the harmless attack upon Crispi, at Rome, on the 16th of June, and especially the much keener emotion produced by the death of the President of the French Republic, Sadi Carnot, on the 24th of June. I reproduce here, as documentary evidence, the declaration published by a section of the _Socialist Party of Italian Workers_ in the _Secolo_ of the 27-28 June, and distributed by thousands in Milan as a manifesto, and which was not mentioned by either the Conservative or the Progressive newspapers, who tried by their silence to perpetrate the confusion between socialism and anarchy. Here is the declaration: _The Socialist Party to the Workingmen of Italy._--Down with assassins! "Humanity now understands that life is sacred, and does not tolerate brutal violations of this great principle which is morally the soul of socialism." C. PRAMPOLINI. "He who struggles for the right to life, in exchange for his labor, condemns every assault upon human life,--whether it be the work of bourgeois exploitation in factories, or of the bombs or daggers of unintelligent revolutionists. "The Socialist Party which has this principle for a shibboleth, which expects everything from the class-conscious organization of the working class, execrates the crime committed against the person of the President of the French Republic, as a brutal deed, as the negation of every principle of revolutionary logic. "It is necessary to arouse in the proletariat the consciousness of their own rights, to furnish them the _structure_ of organization, and to induce them to _function_ as a new organism. It is necessary to conquer the public powers by the means which modern civilization gives us. "To revolt, to throw at haphazard a bomb among the spectators in a theatre, or to kill an individual, is the act of barbarians or of ignorant people. The _Socialist Party_ sees in such deeds the violent manifestation of _bourgeois_ sentiments.
