This is especially true in the case of a scientific idea, which above all others needs to have a clean bill of health and a good family record. But, unfortunately, the idea we are here considering has a bad record, very bad in fact; for the whole family of Cosmogonies, of which this notion is the only surviving representative, were supposed to have been banished from the land of science long ago, and were all reported dead. Some of them had to be executed by popular ridicule, but most of them died natural deaths, the result of inherited taint, in the latter part of the eighteenth and early nineteenth centuries. It is perfectly astonishing how any of the family could have survived over into the twentieth century, in the face of such an antecedent record. For one of the chief traits of the family as a whole is that of mental disorder of various stages and degrees. Some of them were raving crazy; others were mild and comparatively harmless, except that their drivel had such a disturbing effect on scientific investigations that they had to be put out of the way. It seems such a pity that when this last fellow, early in life, was up before Doctors Huxley and Spencer for examination, he was not locked up or put in limbo forthwith. This is especially unfortunate, because this survivor of an otherwise extinct race has since then produced a large family, some of which it is true have already expired, while the eldest son, Darwinism, was reported in 1901 to be "at its last gasp,"[4] and was even said last year to have had its "tombstone inscription" written by von Hartmann of Germany. But the succession of life idea itself, the father of all this brood, is still certified by those in authority to be healthy and _compos mentis_. The Cosmogony Family is a very ancient one, running back to the time of Plato and Thales of Miletus. Indeed the cuneiform inscriptions of Babylonia seem to indicate that a tribe with very similar characteristics existed several millenniums before the Christian era. But discarding all these, the first men that we need to mention are perhaps Burnet and Whiston, who knew no other way of arriving at geological truth than to spin a yarn about how the world was made. Woodward seems to have had a little better sense, and is named along with Hooke and John Ray as one of the real founders of the science. Unfortunately the brood of Cosmogonists was not dead, for Moro and De Maillet were at this same period spinning their fantastic theories about the origin of things; or as Zittel puts it, "accepted the risks of error, and set about explaining the past and present =from the subjective standpoint=."[5] This tendency we will find to be a birthmark in the family, and will serve to invariably identify any of them wherever found. We must remember this, and apply the test to the modern survivors.
