He is in a sure state of happiness who has a sure prospect that in all parts of his existence he shall have all things he desires. . . All men of reflection, from the age of Socrates, have sufficiently proved that the truest, most constant, and lively pleasure, the happiest enjoyment of life, consists in kind affections to our fellow creatures.
As nature has implanted in every man a desire of his own happiness, and many tender affections towards others. . . and granted to each one some understanding and active powers, with a natural impulse to exercise them for the purposes of these affections; ‘tis plain each one has a natural right to exert his power, according to his own judgement and inclination, for these purposes, in all such industry, labor, or amusements, as are not hurtful to others in their persons or goods.
