The relation between reason and goodness in John Finnis

John Finnis joins Grisez in providing a new foundation for Thomistic natural law theory. To accomplish this, they closely associate good as perfection with good as to be pursued and have both senses grasped together by the practical intellect independently of the speculative intellect. The practical intellect then presents good to the will and motivates it to act for the first time. Since good as perfection is inherently speculative and since the intellect becomes practical only depending on the will, their notion of the practical intellect is incoherent and their new foundation is deeply flawed.
