The Elements are always shifting their Forms, and Transmuting into each other. Therefore don't forget the Saying of Heraclitus; That the Earth dies into Water, Water into Air, Air into Fire, and so Backward. Remember likewise the Story of the Man that Travelled on, without knowing to what place the Way would bring him: And that many People contest the Point with that Reason that Governs the World, and with which they are daily Conversant: And seem perfectly unacquainted with those things which occur daily. Farther, we must not Nod over Business, nor dream away Life, like People who fancy they are mightily employ'd, when they are fast in their Beds. Neither are we to be wholly govern'd by Tradition; For that's like Children, who believe any thing their Parents tell them.
