In The Absence Of Any Other Proof,

Truth Is Ever To Be Found In The Simplicity, And Not In The Multiplicity And Confusion Of Things.

Therefore To The Same Natural Effects We Must, As Far As Possible, Assign The Same Causes.

Now The Smallest Particles Of Matter May Cohere By The Strongest Attractions, And Compose Bigger Particles Of Weaker Virture.... There Are Therefore Agents In Nature Able To Make The Particles Of Bodies Stick Together By Very Strong Attraction. And It Is The Business Of Experimental Philosophy To Find Them Out.

A Man May Imagine Things That Are False, But He Can Only Understand Things That Are True, For If The Things Be False, The Apprehension Of Them Is Not Understanding.

As Attraction Is Stronger In Small Magnets Than In Great Ones In Proportion To Their Bulk, And Gravity Is Greater In The Surfaces Of Small Planets Than In Those Of Great Ones In Proportion To Their Bulk, And Small Bodies Are Agitated Much More By Electric Attraction Than Great Ones; So The Smallness Of The Rays Of Light May Contribute Very Much To The Power Of The Agent By Which They Are Refracted.
