Of solidity see L. b. 2. c. 4. s. 1, 5, 6. If any one ask wt solidity is, let him put a flint between his hands and he will know. Extension of body is continuity of solid, &c.; extension of space is continuity of unsolid, &c.
Why may not I say visible extension is a continuity of visible points, tangible extension is a continuity of tangible points?

Mem. That I take notice that I do not fall in wth sceptics, Fardella[207], &c., in that I make bodies to exist certainly, wch they doubt of.

I am more certain of ye existence & reality of bodies than Mr. Locke; since he pretends onely to wt he calls sensitive knowledge[208], whereas I think I have demonstrative [pg 064] knowledge of their existence—by them meaning combinations of powers in an unknown substratum[209].
M.
Our ideas we call figure & extension, not images of the figure and extension of matter; these (if such there be) being infinitely divisible, those not so.
