"Have not the small Particles of Bodies certain Powers, Virtues, or Forces, by which they act at a distance, not only upon the Rays of Light for reflecting, refracting and inflecting them, but also upon one another for producing a great Part of the Phaenomena of Nature? For it's well known, that Bodies act upon one another by the Attractions of Gravity, Magnetism and Electricity; and these instances shew the Tenor and Course of Nature, and make it not improbable that there may be more attractive Powers than these... "The Attractions of Gravity, Magnetism, and Electricity, reach to very sensible distances, and so have been observed by vulgar Eyes, and there may be others which reach to so small distances as hitherto escape Observation... "Now the smallest Particles of Matter may cohere by the strongest Attractions, and compose bigger Particles of weaker Virtue; and many of these may cohere and compose bigger Particles whose Virtue is still weaker, and so on for diverse Successions, until the Progression end in the biggest Particles on which the Operations in Chemistry, and the Colours of natural Bodies depend, and which by cohering compose Bodies of a sensible Magnitude." [Isaac Newton, Opticks, Book Three, Part I, Question 31; London 1717]
