Joseph Addison wrote in The Spectator (Issue #221): "Those who are versed in the Philosophy of Pythagoras, and swear by the Tetrachtys, that is, the number Four, will know very well that the number Ten, which is signified by the letter X, (and which has so much perplexed the town) has in it many particular powers; that it is called by platonick writers the complete number; that One, Two, Three, and Four put together make up the number Ten, and that Ten is all. But these are not mysteries for ordinary readers to be let into. A man must have spent many years in hard study before he can arrive at a knowledge of them."
