I have stated, and (I hope) have shown elsewhere[2] what may be understood by "pathological" social phenomena, namely, an abnormal unhealthy condition of the popular mind in the sense of a general aberration of the intellect of the masses, as is possibly the case in what is known as Anti-Semitism. But even in this limited sense it appears quite inadmissible and incorrect to call Anarchism a pathological phenomenon. Let us be fair and straightforward, if we wish to learn; let us be just, even if we are to benefit our most dangerous enemies; for in the end we shall benefit ourselves. With Anarchism there is no question of transitory anomalies of the public mind, but of a well defined condition which is visibly increasing and which is necessarily connected with all previous and accompanying conditions; it is a question of ideas and opinions which are the logical, even if in practice inadmissible, development of views that have long been well known and recognised by the majority of civilised men. A further test of every unhealthy phenomenon, namely, its local character, is entirely lacking in Anarchism; for we meet with it to-day extending all over the world, wherever society has developed in a manner similar to our own; we meet it not merely in one class, but see members of all classes, and especially members of the upper classes, attach themselves to it. The fathers, as we may call them, of the Anarchist theory are almost entirely men of great natural gifts, who rank high both intellectually and morally, whose influence has been felt for half a century, who have been born in Russia, Germany, France, Italy, England, and America, men who are as different one from another as are the circumstances and environment of their respective countries, but who are all of one mind as regards the theory which we mentioned at the beginning of this chapter.

And that is what Anarchism undoubtedly is: a theory, an idea, with all the failings and dangers, but also with all the advantages which a theory always possesses, with just as much, and only as much, validity as a theory can demand as its due, but at any rate a theory which is as old as human civilisation, because it goes back to the most powerful civilising factor in humanity. * * * * *
