Thus, if it be asked, if the invisible and intangible distance, interposed betwixt two objects, be something or nothing: It is easy to answer, that it is SOMETHING, VIZ.

a property of the objects, which affect the SENSES after such a particular manner.

If it be asked whether two objects, having such a distance betwixt them, touch or not: it may be answered, that this depends upon the definition of the word, TOUCH.

If objects be said to touch, when there is nothing SENSIBLE interposed betwixt them, these objects touch: it objects be said to touch, when their IMAGES strike contiguous parts of the eye, and when the hand FEELS both objects successively, without any interposed motion, these objects do not touch.

The appearances of objects to our senses are all consistent; and no difficulties can ever arise, but from the obscurity of the terms we make use of.
If we carry our enquiry beyond the appearances of objects to the senses, I am afraid, that most of our conclusions will be full of scepticism and uncertainty.
