Course Lecturing Learn To Classify





The definition of science as "knowledge classified," while leaving much

to be said, is perhaps, as satisfactory as any that could be condensed

into two words.



A trained capacity for classification is wholly indispensable in a

course lecturer. We all know the speaker who announces his subject and

then rambles off all over the universe. With this speaker, everybody

knows that, no matter what the subject or the occasion of the meeting,

it is going to be the same old talk that has done duty, how long nobody

can remember.



If, under the head of "surplus value" you talk twenty minutes about

prohibition, how will you avoid repetition when you come to speak on the

temperance question?



The surest way to acquire this qualification is to study the sciences.

The dazzling array of facts which science has accumulated, owe half

their value to the systematization they have received at the hands of

her greatest savants.



It is impossible to take a step in scientific study without coming face

to face with her grand classifications. At the very beginning science

divides the universe into two parts, the inorganic and the organic. The

inorganic is studied under the head of "physics"; the organic, under

"biology."



Physics (not the kind one throws to the dogs, of course) is then

subdivided into Astronomy, Chemistry, and Geology, while Biology has its

two great divisions, Zoology (animals) and Botany (plants), all these

having subdivisions reaching into every ramification of the material

universe, which is the real subject matter of science, being as it is

the only thing about which we possess any "knowledge."



Another way of learning to classify is to select a subject and then

"read it up." Here is a good method:



Take a ten-cent copy book, the usual size about eight by six inches and

begin on the first inside page. Write on the top of the page, left side,

a good subject, leaving that page and the one opposite to be used for

that question. Turn over and do the same again on the next page with

some other subject. This practice of selecting subjects, in itself, will

be valuable training.



In the search for subjects take any good lecture syllabus and select

those about which you have a fair general idea. You will soon learn to

frame some of your own. Good examples of standard questions are "Free

Will," "Natural Selection," "Natural Rights," "Economic Determinism,"

"Mutation," "Individualism," and a host of others, all of which have a

distinct position in thought, and about which there is a standard

literature.



Then, in your general reading, whenever you come across anything of

value in any book, on any of your listed subjects, turn to the page in

your copy book and enter it up, author, volume, chapter and page. When

you come to lecture on that question, there it will be, or, at least,

you will know just where it is.



Of course, the two pages devoted to "Natural Rights" would mention,

among other references, Prof. David G. Ritchie's book on "Natural

Rights"; and the eighth essay of Huxley's First Volume of "Collected

Essays," in which he annihilates Henry George.



All this means an immense quantity of reading, but unless you have

carefully read and weighed about all the best that has been said on any

question, your own opinions will have no value, and it is simply

presumption to waste the time of an audience doling out a conception

that, for aught you know, may have been knocked in the head half a

century ago.



What can be more tiresome than the prattle about "absolute justice,"

"eternal truth," "inalienable rights," "the identity of the ethics of

Christianity with those of Socialism," and a lot of other theories,

which lost their footing in scientific literature and transmigrated to

begin a new career among the uninformed, sixty years ago.



Of course, some of these positions look all right to you now, but when

you learn what has been revealed about them by the science and

philosophy of the last six decades, they will seem about as rational as

the doctrine of a personal devil or the theory of a flat earth.



And until your reading is wide enough to give you this view of them, you

had better not attempt course lecturing in the twentieth century.
