If the whiteness of the swan, produced by its Reason-Principle, is given at its birth, are we to affirm Passion of the swan on its passing into being? If, on the contrary, the swan grows white after birth, and if there is a cause of that growth and the corresponding result, are we to say that the growth is a Passion? Or must we confine Passion to purely qualitative change?
One thing confers beauty and another takes it: is that which takes beauty to be regarded as patient? If then the source of beauty — tin, suppose — should deteriorate or actually disappear, while the recipient — copper — improves, are we to think of the copper as passive and the tin active?
Take the learner: how can he be regarded as passive, seeing that the Act of the agent passes into him [and becomes his Act]? How can the Act, necessarily a simple entity, be both Act and Passion? No doubt the Act is not in itself a Passion; nonetheless, the learner coming to possess it will be a patient by the fact of his appropriation of an experience from outside: he will not, of course, be a patient in the sense of having himself performed no Act; learning — like seeing — is not analogous to being struck, since it involves the acts of apprehension and recognition.
