From The Rambler, No. 148 (August 17, 1751)

To have voluntarily become to any being the occasion of its existence, produces an obligation to make that existence happy. To see helpless infancy stretching out her hands, and pouring out her cries in testimony of dependence, without any powers to alarm jealousy, or any guilt to alienate affection, must surely awaken tenderness in every human mind; and tenderness once excited will be hourly increased by the natural contagion of felicity, by the repercussion of communicated pleasure, by the consciousness of the dignity of benefaction.
