quantity of matter than to a leffer. Is it then 
conceivable, zhat an unthinking being fhould 
be endued with an activity which it regulates 
and varies in proportion to the fituation, di- 
ftance, and magnitude of another body, 
whilft it is fappofed to be not in the leaft in- 
"fluenced or acted upon by that other body, 
or any other being whatfoever? If this fhall 
be maintained, another queftion will arife. 
By what actions, or what ftronger language 
than this, can any man convince his neighbour 
of his own reafon or underftanding? Itis pre- 
fumed, that a higher degree of evidence will 
hardly be required in phyfical matters, than 
what we have for the life and exiftence of 
one another: the voice of nature as loudly 
declares the origin of gravity, that ruling 
principle which binds the parts of the fyftem 
together. From the circumftances obler- 
vable in the apparent mutual tendency of bo- 
3 dies, we are naturally led to conclude, that 
: gravitation is the effect of the continued

ternal. A power fo conftant, fo regular,
