WE have now concluded our examination of the general principles of sympathetic magic. The examples by which I have illustrated them have been drawn for the most part from what may be called private magic, that is from magical rites and incantations practised for the benefit or the injury of individuals. But in savage society there is commonly to be found in addition what we may call public magic, that is, sorcery practised for the benefit of the whole community. Wherever ceremonies of this sort are observed for the common good, it is obvious that the magician ceases to be merely a private practitioner and becomes to some extent a public functionary. The development of such a class of functionaries is of great importance for the political as well as the religious evolution of society. For when the welfare of the tribe is supposed to depend on the performance of these magical rites, the magician rises into a position of much influence and repute, and may readily acquire the rank and authority of a chief or king. The profession accordingly draws into its ranks some of the ablest and most ambitious men of the tribe, because it holds out to them a prospect of honour, wealth, and power such as hardly any other career could offer. The acuter minds perceive how easy it is to dupe their weaker brother and to play on his superstition for their own advantage. Not that the sorcerer is always a knave and impostor; he is often sincerely convinced that he really possesses those wonderful powers which the credulity of his fellows ascribes to him. But the more sagacious he is, the more likely he is to see through the fallacies which impose on duller wits. Thus the ablest members of the profession must tend to be more or less conscious deceivers; and it is just these men who in virtue of their superior ability will generally come to the top and win for themselves positions of the highest dignity and the most commanding authority. The pitfalls which beset the path of the professional sorcerer are many, and as a rule only the man of coolest head and sharpest wit will be able to steer his way through them safely. For it must always be remembered that every single profession and claim put forward by the magician as such is false; not one of them can be maintained without deception, conscious or unconscious. Accordingly the sorcerer who sincerely believes in his own extravagant pretensions is in far greater peril and is much more likely to be cut short in his career than the deliberate impostor. The honest wizard always expects that his charms and incantations will produce their supposed effect; and when they fail, not only really, as they always do, but conspicuously and disastrously, as they often do, he is taken aback: he is not, like his knavish colleague, ready with a plausible excuse to account for the failure, and before he can find one he may be knocked on the head by his disappointed and angry employers.
