The primordial forms of all sciences, taken back beyond the rise of writing, lie ultimately in the magic of prehistory. Just as modern man wants to indicate what consequences his actions will have, so also a man who grows up in the magical way of life seeks to find a ground for everything and to find consequences of his action. Magic as a more or less clearly formulated system of tenets shot through with emotional elements, can become independent only when magicians, acting as specialists, proclaim the consequences of certain customs, either esoterically,. e. g. at certain rituals, or exoterically as popular education. The magicians tell what cases are to count as 'equal', and when certain measures shall be used.
