David Hume,
Treatise of Human Nature/Book 1…
(1739)
“ Add to this, that, properly speaking, solidity or impenetrability is nothing, but an impossibility of annihilation, as [1] has been already observ'd: For which reason 'tis the more necessary for us to form some distinct idea of that object, whose annihilation we suppose impossible. An impossibility of being annihilated cannot exist, and can never be conceived to exist, by itself; but necessarily requires some object or real existence, to which it may belong. ”
