De Plantatione

For how can it be looked upon as anything but a prodigy, for that which would dissolve another thing, to be held together by that which it would dissolve: that is to say, for water to be held together by earth; and again, for that which is the hottest of all things to be placed upon that which is the coldest without its nature being destroyed, that is to say, for fire to be placed upon air? And these are the elements of this most perfect plant; but the very great and all productive plant is this world, of which the aforesaid branches are the main shoots.

We must now therefore consider where God placed its foundations, and in fact, what foundation it has on which it is supported, as a statue is on a pedestal; certainly we cannot imagine that any body is left outside and wandering about, since God has worked up and arranged every imaginable material throughout the whole universe.
