There exists, finally, a somewhat numerous class of honest but timid souls who, too intelligent to take the Christian dogmas seriously, reject them in detail, but have neither the courage nor the strength nor the necessary resolution to summarily renounce them altogether. They abandon to your criticism all the special absurdities of religion, they turn up their noses at all the miracles, but they cling desperately to the principal absurdity; the source of all the others, to the miracle that explains and justifies all the other miracles, the existence of God. Their God is not the vigorous and powerful being, the brutally positive God of theology. It is a nebulous, diaphanous, illusory being that vanishes into nothing at the first attempt to grasp it; it is a mirage, an _ignis fatuus_ that neither warms nor illuminates. And yet they hold fast to it, and believe that, were it to disappear, all would disappear with it. They are uncertain, sickly souls, who have lost their reckoning in the present civilization, belonging to neither the present nor the future, pale phantoms eternally suspended between heaven and earth, and occupying exactly the same position between the politics of the bourgeois and the Socialism of the proletariat. They have neither the power nor the wish nor the determination to follow out their thought, and they waste their time and pains in constantly endeavoring to reconcile the irreconcilable. In public life these are known as bourgeois Socialists. With them, or against them, discussion is out of the question. They are too puny. But there are a few illustrious men of whom no one will dare to speak without respect, and whose vigorous health, strength of mind, and good intention no one will dream of calling in question. I need only cite the names of Mazzini, Michelet, Quinet, John Stuart Mill.[2] Generous and strong souls, great hearts, great minds, great writers, and the first the heroic and revolutionary regenerator of a great nation, they are all apostles of idealism and bitter despisers and adversaries of materialism, and consequently of Socialism also, in philosophy as well as in politics. Against them, then, we must discuss this question.
