2. Simple modes of motion.
To slide, roll, tumble, walk, creep, run, dance, leap, skip, and abundance of others
that might be named, are words which are no sooner heard but every one who understands English has presently
in his mind distinct ideas, which are all but the different modifications of motion. Modes of motion answer those
of extension; swift and slow are two different ideas of motion, the measures whereof are made of the distances of
time and space put together; so they are complex ideas, comprehending time and space with motion.
