His skill as a draftsman and colorist appears in his zoölogical works, and besides this professional work he has in his portfolios more than a thousand original sketches in oil and water colors of scenery from Norway to Malay; in fact, of every quarter of the globe except America. When he was twenty-five he was so captivated by Sicily that he almost gave up science to adopt landscape painting as a career.
The freedom of instruction which Jena has enjoyed to an exceptional degree, even for Germany, Haeckel ascribes in part to the fact that the university is located in one of the minor States, remote from the great political centers, and derives its support from several sources. "We had four masters," said Professor Haeckel to me, "and so we remained free." He closes his address of 1892 on "Monism as the Bond Between Religion and Science" with a grateful eulogy of the Grand Duke Karl Alexander, who, he says,
has during a prosperous reign of forty years constantly shown himself an illustrious patron of science and art; as Rector Magnificentissimus of our Thuringian university of Jena, he has always afforded his protection to its most sacred palladium—the right of free investigation and the teaching of truth.
We see that Haeckel has reason to be grateful for the protection accorded him when we realize that he first championed the cause of Darwin in 1862, only three years after the publication of "The Origin of Species", and that twenty years after that professors were being dismissed from American universities or were viewed with suspicion for believing in evolution. Even to-day a man of Haeckel's views on religion and his blunt way of expressing them would find it difficult to retain his chair in most American universities. In Germany a professor may be almost anything he pleases—except a Socialist—and hold his job.
A song of the Jena students contains the couplet
"Wer die Wahrheit kennet und saget sie nicht,
Der ist fürwahr ein erbärmlicher Wicht!"
But according to Haeckel the students of Berlin University have a different version:
Wer die Wahrheit kennet und saget sie frei,
Der kommt in Berlin auf die Stadtvogtei![1]
The grand duchy of Saxe-Weimar-Eisenach, of which Jena is one of the chief cities, has about the same area as Rhode Island and fewer inhabitants. It was the first of the German States to acquire a constitutional government, in 1816. The community is rather rigidly orthodox in the evangelical Lutheran faith, which it was among the first to espouse. How well the Grand Duke Karl Alexander maintained the Jena tradition of Lehrfreiheit is shown by an incident that happened when Haeckel first scandalized Germany by championing the cause of Darwinism. A prominent theologian came to the palace of the Grand Duke at Weimar and begged him to dismiss the heretic professor. Karl Alexander asked: "Do you suppose that he really believes the things he publishes?"
"Most certainly he does," was the prompt reply. "Very well," said the Grand Duke, "then the man simply does the same as you do."
