Book 1, Ch. 37 Variant: Nature has so contrived that to men, though all things are objects of desire, not all things are attainable; so that desire always exceeds the power of attainment, with the result that men are ill-content with what they possess and their present state brings them little satisfaction. Hence arise the vicissitudes of their fortune. (as translated by LJ Walker and B Crick)
