in a school of political science. The
medical lectures preserve a sobriety in discussing sundry biological
problems not always present in advanced courses of biology. Both
lecturers, in both instances, are scientific men, both are faithful to
the truths of science, but as a distinguished economist, who in his
early years had been accused of being an advanced socialist, said,
after he had won a comfortable fortune by judicious investments in
business, banking, and realty, to a friend of earlier and far-distant
years: "My principles remain exactly the same, but, I admit, my point
of view has changed." There is not one biology of the medical school,
another of the biological laboratory. Neither does the body of law
differ in a law school or in a school of political science. The
principles remain exactly the same. Of necessity, however, the point
of view has changed and treatment has changed with it. So has
responsibility.

The subject offers some difficulties. The analogy is not at all points
exact. Medicine and law have a definite body of doctrine. Schools of
biology and political science have not, but granting all this, it
still remains true that exactly as the law student and the medical
student must have what is defined, established, and unmistakable in
the world of law and of life, so the student looking to journalism
needs and must have what is defined, established, and unmistakable in
economics and political science. Here, again, no one will pretend that
the usual college course in either of these branches is taught with
the same determination to keep within the same metes and bounds of
recorded, tested, and ascertained facts as is true of courses in
physics, chemistry, and biology. The boundary marked is less distinct.
The periodic law by which the atomic values of elements are
established is more definite than the periodic law under which wealth
is distributed through society, though in the end some Mendelleeff
will record the periodic law of social elements in their composition
and action. Research is needed and must be free. Theory and
speculation are as necessary to secure an experiment and observation.
The principle is clear, however, that the student who is to make
professional use of a topic needs to have a definite and established
instruction, not required in one to whom topic is incidental. The
medical student or law student who has a new view of economic results
or a new theory of the cause and purpose
