 As we have seen, Green treats perfection, freedom, and the common good as regulative ideals at which we aim, which humanity better approximates over time. This is illustrated in the gradual expansion of the scope of the common good to include persons previously excluded from full moral personality, such as slaves, women, and workers (PE Book III, esp. §§205–206, 271, 285). It is also illustrated in our progressively more adequate conception of the conditions of self-realization and the demands on government to promote the perfection of its citizens. Like Hegel, Green has a progressive view of history, which he sees as the progressively more adequate realization of the demands of perfection, the common good, and true freedom (PE §§172–76; “Freedom,” Works II 330; LPPO §6).
