… from Thomas Sowell’s Best 1987 volume, page 12; Conflict of vision:

They are taken as natural facts of life, the basic constraint in his vision. The basic moral and social challenge was to make the most of the possibilities within that limit rather than waste energies in trying to change human nature—an attempt Smith found futile and futile.
