A doctor kills his patient [vi-zton] scientifically; a dentist cracks the jaw in extracting a tooth; a surgeon breaks the leg which he cannot set: _Science_ is satisfied--"all was scientifically done!" A man spends his life in looking at the stars; he is a man of wonderful science. Another keeps a List of fair and rainy days during twelve moons; his scientific attainments are respected and his _observations_ recorded, as if the fate of the harvests were involved. You will hear of a man of marvellous science, before whom ordinary scientific men stand uncovered in silence; he has discovered a new kind of _tadpole_, and added another to the already interminable _terms_ of natural Science. I have heard one of these learned _professors_ [pho-phe-sti] say wisely, "He is a benefactor of the race who makes two blades of grass to grow where one grew before;" "but," he added, "he is a greater who teaches mankind how to do this." In this way, wishing to show that an _idiot_ might chance to find a way to double his growth of grass, but would be incapable of discovering the _cause_; so that, probably, the accident would die with the finder. A wise man would, at once, look for the reason, and finding _that_, be able to secure the benefit for all time. This knowledge of cause is the kind called _Science_. The explanation is familiar to us. In our Flowery Kingdom, the master teaches the rules, and the artificer puts them in practice. We call him an Artisan who has knowledge of an Art: we call him who knows how things ought to be done, and who examines into things so as to comprehend the best modes of doing, simply a teacher, or master. We do not see that his knowledge, without actual performance, makes him a great man--a man of Science (as the Barbarians have it). Indeed, if a man do a thing merely mechanically, as a horse turns a mill, no doubt he is an ignorant artisan. Still, this stupidity does not exalt, in any degree, the nature of the knowledge of a brighter man: this one is only an intelligent artisan. On the whole, then, it seemed to me that the Barbarians, for the most part very ignorant, were easily imposed upon by those who, having leisure, mastered the multiform _terms_ (or some of them) used by the teachers of Natural History in its various departments. These, too, idle and with some ambition to be known, easily fancied that the dry knowledge of words _was_ knowledge; and discovering with surprise at first, but soon with great complacency, how very little one need to know to be ranked with men of _Science_, at length prided themselves upon the very trivialities which otherwise would have been unvalued. In fact, finally imposed upon themselves as they imposed upon others, and really believed those trifles _to be_ important, because confined to those who paraded them as Scientific. These busy, idle triflers in words become _the men of Science_.
