The old notion probably was that a magician could sympathetically injure any person who ate out of a pot by means of the impression which the pot had left on the ashes; or, to be more explicit, contagious magic was supposed to work through the impression of the pot to the pot itself, through the pot to the meat contained in it, and finally through the meat to the eater. §4. _The Magician’s Progress_ [Sidenote: Public and private magic. The public magician who practises his art for the good of the whole community, enjoys great influence and may rise to be a chief or king.] 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 {p215} 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.
