HYL. It was.

PHIL. Is it not the very same reasoning to conclude, there is no
extension or figure in an object, because to one eye it shall seem
little, smooth, and round, when at the same time it appears to the other,
great, uneven, and regular?

HYL. The very same. But does this latter fact ever happen?

PHIL. You may at any time make the experiment, by looking with one eye
bare, and with the other through a microscope.

HYL. I know not how to maintain it; and yet I am loath to give up
EXTENSION, I see so many odd consequences following upon such a
concession.

PHIL. Odd, say you? After the concessions already made, I hope you will
stick at nothing for its oddness. But, on the other hand, should it not
seem very odd, if the general reasoning which includes all other
sensible qualities did not also include extension? If it be allowed that
no idea, nor anything like an idea, can exist in an unperceiving
substance, then surely it follows that no figure, or mode of extension,
which we can either perceive, or imagine, or have any idea of, can be
really inherent in Matter; not to mention the peculiar difficulty there
must be in conceiving a material substance, prior to and distinct from
extension to be the SUBSTRATUM of extension. Be the sensible quality
what it will--figure, or sound, or colour, it seems alike impossible it
should subsist in that which doth not perceive it.
