Context

“it must be shown the good road it is in search of, secured from the seductive influences of individual wills, taught to see times and spaces as a series, and made to weigh the attractions of present and sensible advantages against the danger of distant and hidden evils. The individuals see the good they reject; the public wills the good it does not see. All stand equally in need of guidance. The former must be compelled to bring their wills into conformity with their reason; the latter must be taught to know what it wills. If that is done, public enlightenment leads to the union of understanding and will in the social body:” source
