A man who has no family is more strongly attracted towards his friends and neighbours; and if absent from these, he naturally falls into an acquaintance with those of his own city or country who chance to be in the same place. Two Englishmen meeting at Rome or Constantinople, soon run into familiarity. And in China or Japan, Europeans would think their being so a good reason for their uniting in particular converse. Farther, in case we suppose ourselves translated into Jupiter or Saturn, and there to meet a Chinese or other more distant
Natural reflections
native of our own planet, we should look on him as a near relation, and readily commence a friendship with him. These are natural reflections, and such as may convince us that we are linked by an imperceptible chain to every individual of the human race.
The several great bodies which compose the solar system are kept from joining together at the common centre of gravity by the rectilinear motions the author of nature has impressed on each of them; which, concurring with the attractive principle, form their respective orbits round the sun; upon the ceasing of which motions, the general law of gravitation that is now thwarted, would show itself by drawing them all into one mass. After the same manner, in the parallel case of society, private passions
Mutual gravitation
and motions of the soul do often obstruct the operation of that benevolent uniting instinct implanted in human nature; which, notwithstanding, doth still exert, and will not fail to show itself when those obstructions are taken away.
The mutual gravitation of bodies cannot be explained any other way than by resolving it into the immediate operation of God, who never ceases to dispose and actuate his creatures in a manner suitable to their respective beings. So neither can that reciprocal attraction in the minds of men be accounted for by any other cause. It is not the result of education, law, or fashion; but is a principle originally ingrafted in the very first formation of the soul by the author of our nature.
And as the attractive power in bodies
Sympathy in our nature
is the most universal principle which produceth innumerable effects, and is a key to explain the various phenomena of nature; so the corresponding social appetite in human souls is the great spring and source of moral actions. This it is that inclines each individual to an intercourse with his species, and models every one to that behaviour which best suits with the common well-being. Hence that sympathy in our nature, whereby we feel the pains and joys of our fellow creatures. Hence that prevalent love in parents towards their children, which is neither founded on the merit of the object, nor yet on self-interest. It is this that makes us inquisitive concerning the affairs of distant nations, which can have no influence on our own. It is this that extends our care to future generations,
