Rorty's next paragraph begins: 'The danger to human freedom of such success is minimal, since the "in principle" clause allows for the probability that the determination of the initial conditions (the antecedent states of microstructures) will be too difficult to carry out except as an occasional pedagogical exercise' (PMN, p . 354). This is disastrous. Freedom cannot be grounded in ignorance. Or else we would have to reckon a falling man free in virtue of his ignorance of gravity or the law of fall. And the most free would be the least pour-soi, the furthest from 'the logical space of reasons, of justifying and being able to justify what one says' (PMN, p. 389).
