"When every individual person labours a-part, and only for himself, his force is too small to execute any considerable work; his labour being employ’d in supplying all his different necessities, he never attains a perfection in any particular art; and as his force and success are not at all times equal, the least failure in either of these particulars must be attended with inevitable ruin and misery. Society provides a remedy for these three inconveniences. By the conjunction of forces, our power is augmented: By the partition of employments, our ability en creases: And by mutual succor we are less expos’d to fortune and accidents. ’Tis by this additional force, ability, and security, that society becomes advantageous."
