The student of psychology, however, cannot fail to see that the disposition that led so many members of Haeckel’s family into the legal profession was also developed in himself to some extent. There is perhaps no other scientist of his time with such an imperious craving for clearness, for clean lines and systematic arrangement. At least in the whole of the Darwinian period no other has made so great an effort to convert the scattered flight of phenomena in the realm of life into the even course of so many fixed “laws.” In many of his writings this tendency to formulate laws is so pronounced that the layman instinctively has an impression of dogmatism on the part of the author. This has been grossly misunderstood, and made to play an important part in the controversial work of his opponents. The truth is that this sharp outlook and pronounced tendency to formulate clear and unambiguous “laws” in the animal and plant worlds is a matter of temperament as much as of judgment. It is very possible that we have here an hereditary trait, an innate aversion for disorder and confusion—for a thoughtless rushing ahead without clear ideas and plan. The trait was the more important and helpful as a man of Haeckel’s type was sure to be one of the most active revolutionaries in his science, even apart from Darwinian ideas. It would be difficult to find another reformer in any great province of thought who, immediately after effecting a complete overthrow of the older ideas, has hastened so quickly to build up the new, to devise a nomenclature and a classification down to the smallest details, and hand on at once to his successors a splendid order once more. Zoology, which seemed to crumble into chaos after Darwin’s victory and the collapse of the old framework, came out of Haeckel’s hands, after barely two years’ work, in the shape of a new and graceful Darwinistic structure—not, indeed, perfect and finally completed, but entirely habitable for the young generation. They could add new stones as they thought fit, or pierce new windows, and so on; but at all events the chaos was terminated at a critical moment by this iron man of order. I will only add, to complete the picture, that one of the three doctorates that Haeckel holds to-day is that of law (an honorary degree), in addition to his qualifications in philosophy and medicine. He now only lacks the theological degree, but I fear that he will neither take the trouble to secure it nor have it conferred on him as an honorary distinction for his merit in that department.
