1790s, Discourse to the Theophilanthropists (1798)
Context: As to that which is called nature, it is no other than the laws by which motion and action of every kind, with respect to unintelligible matter, is regulated. And when we speak of looking through nature up to nature's God, we speak philosophically the same rational language as when we speak of looking through human laws up to the power that ordained them.
God is the power of first cause, nature is the law, and matter is the subject acted upon.
But infidelity by ascribing every phenomenon to properties of matter, conceives a system for which it cannot account, and yet it pretends to demonstration. It reasons from what it sees on the surface of the earth, but it does not carry itself on the solar system existing by motion. It sees upon the surface a perpetual decomposition and recomposition of matter. It sees that an oak produces an acorn, an acorn an oak, a bird an egg, an egg a bird, and so on. In things of this kind it sees something which it calls a natural cause, but none of the causes it sees is the cause of that motion which preserves the solar system.

Query 28 : Are not all Hypotheses erroneous in which Light is supposed to consist of Pression or Motion propagated through a fluid medium?
Opticks (1704)
Context: To make way for the regular and lasting Motions of the Planets and Comets, it's necessary to empty the Heavens of all Matter, except perhaps some very thin Vapours, Steams or Effluvia, arising from the Atmospheres of the Earth, Planets and Comets, and from such an exceedingly rare Æthereal Medium … A dense Fluid can be of no use for explaining the Phænomena of Nature, the Motions of the Planets and Comets being better explain'd without it. It serves only to disturb and retard the Motions of those great Bodies, and make the frame of Nature languish: And in the Pores of Bodies, it serves only to stop the vibrating Motions of their Parts, wherein their Heat and Activity consists. And as it is of no use, and hinders the Operations of Nature, and makes her languish, so there is no evidence for its Existence, and therefore it ought to be rejected. And if it be rejected, the Hypotheses that Light consists in Pression or Motion propagated through such a Medium, are rejected with it.
And for rejecting such a Medium, we have the authority of those the oldest and most celebrated philosophers of ancient Greece and Phoenicia, who made a vacuum and atoms and the gravity of atoms the first principles of their philosophy, tacitly attributing Gravity to some other Cause than dense Matter. Later Philosophers banish the Consideration of such a Cause out of natural Philosophy, feigning Hypotheses for explaining all things mechanically, and referring other Causes to Metaphysicks: Whereas the main Business of natural Philosophy is to argue from Phenomena without feigning Hypotheses, and to deduce Causes from Effects, till we come to the very first Cause, which certainly is not mechanical.
