This folly is equalled, if not out-done, by those who refuse to recognize authority in science and thought. When a man claims to have a new and fundamental discovery in astronomy, and at the same time speaks slightingly of the researches of physicists such as Newton, Kant, and Laplace, it is fairly safe to conclude that you are listening to a fool who has nothing to say worthy of a second thought. Not until one has trodden every rung of the ladder which has been previously trodden, is he able to mount a step higher. And it is the performance of this task, wholly, or at least in the first part, that constitutes the one so doing an “authority.”

How often does one hear an addle-brained, know-nothing say: “I recognize no authority; I think for myself.” How shall one think without ideas? And how is it possible to obtain ideas apart from the acquisition of knowledge? And where can knowledge be obtained except from those who have it?

All “authority” in science and thought is founded on knowledge of the subject in question. Socialists quote Karl Marx as an authority on political economy, because his writings prove that he knew more about the production and distribution of wealth than any man of his century. Lavoisier is an authority in chemistry, because he know more about the composition of substances than any three of his contemporaries.

But much confusion has been wrought, by men of undisputed authority in their own field, pronouncing positive verdicts in departments where their opinions had no value. What a great composer has to say about the value of a certain note must be respectfully considered as being of importance, but, unless he has studied geology, his opinions on the probable origin or age of the Rocky Mountains will have no more value, and may have less than those of the policeman on the nearest corner.

An excellent example of the confusion which may arise in this way, was given to the world in 1877, at the Congress of Naturalists held at Munich in September of that year. At that time the naturalists of Europe were divided into two opposing camps, one accepting and the other rejecting the Darwinian theory of “natural selection.” The leaders of both divisions were Germans, though a preponderance of the Germans favored Darwin, whilst the French, still under the influence of, or agreeing with, Flourens, although he had been dead a decade, were almost unanimously opposed.

The honors of leading the fight for Darwinism, at the Munich Congress, fell to Haeckel, and on the 18th of September he threw down the gage in a brilliant address in which he defended the ideas of the great Englishman. Haeckel also advocated the teaching of evolution in the schools. The battle raged back and forth between the two armies, until Virchow, the great pathologist, dropped a bombshell in the Congress by boldly asserting: “Darwinism leads directly to Socialism.”

Here biological arguments ceased. The only thing in order was to clear the skirts of Darwinism of the terrible charge of being socialistic. Of course this task fell to Haeckel, and he was loyally assisted by Oscar Schmidt.

Writing in “Ausland” two months later Schmidt said: “If the Socialists were prudent they would do their utmost to kill by silent neglect, the theory of descent, for that theory most emphatically proclaims that the Socialist ideas are impracticable.”

Haeckel replied to Virchow at some length, and as that reply is rather difficult to obtain I will give it here in full as quoted by Ferri, and translated by Robert Rives La Monte:

“As a matter of fact, there is no scientific doctrine which proclaims more openly than the theory of descent, that the equality of individuals, toward which Socialism tends, is an impossibility, that this chimerical equality is in absolute contradiction with the necessary and, in fact, universal inequality of individuals.
