Rational Unified Process (RUP)

19. With rule B we ask if the vegetative power is accessible to the senses. We answer that it is accessible to the senses in a one way because it is joined to, or composed with the sensitive power in the subjects in which it exists. In addition, it is accessible in another way through the voice, when the affatus names the vegetative and the hearing hears this name. However, the other senses cannot sense the vegetative power at all. Here, the intellect realizes that the affatus is a sense that delivers an audible signal to the ear after having sensed an object.

20. With the first species of rule C we ask what the vegetative power is. We answer that it is a power that transmutes one species into another, as we see in animals in which it transmutes food into flesh, and in plants in which it transmutes the elementative into itself.

21. With the second species of rule C we ask what the vegetative power has in itself essentially and consubstantially. We answer that it has its constitutive correlatives with which it does its work, which are its vegetative, vegetable and vegetating. Now the vegetative vegetates all peregrine vegetable objects in its innate vegetable part, just as the sensitive faculty senses all peregrine sensible objects in its innate sensible part, and just as the heater heats all peregrine heatable objects in its innate heatable part.

22. With the third species of rule C we ask what the vegetative power is in other things. We answer that it is the foundation of the sensitive faculty, and it is founded in the elementative. With reference to the predicates, it is identified with the subject in which it exists so that it is a substantial part of the substance in which it exists, while the vegetative power’s quantity depends on the quantity of the elementative power, and the same can be said about its quality, relation etc. Here the intellect realizes that the vegetative power stands above the elementative; however, the intellect wonders whether this relation is accidental until it remembers that substantial relation uses accidental relation as an instrument and habit by means of which it is active in the subject in which it exists when substance acts through its accidents.

23. With the fourth species, we ask what the vegetative power has in other things. We answer that it has its substance in the substance of the elementative power, it has its quantity in the quantity of the elementative power, and so on with the other predicates. Here, the intellect sees how the vegetative power is disposed and located in the elementative.

24. With the first species of rule D we ask what the vegetative power originates from. We say that it arises in its own specific principles by means of which it acts.

25. With the second species, we ask what the vegetative power is made of. We say that it is made of its correlatives.

26. With the third species, we ask to whom the vegetative power belongs. We answer that it belongs to the subject in which it exists, as a part belongs to its whole and as an instrument belongs to an agent. The vegetative power is a part of an animal through which and with which it lives and acts, and likewise, plants live through the vegetative power and with the vegetative power.

27. With the first species of rule E we ask why the vegetative power exists. We answer that it exists because it is constituted of its consubstantial parts, namely its correlatives.

28. With the second species of rule E we ask why the vegetative power exists. We answer that it exists so that vegetated things can exist and so that it can live, feed, grow and transmute one species into another through generation.

29. With the first species of rule F we ask if the vegetative power has continuous quantity in a subject in which it exists. We answer that it does, so that it can be in continuous motion.

30. With the second species of rule F we ask if the vegetative power has discrete quantity. We say that it does, so that it can be in successive motion. However, the intellect wonders: how can the vegetative power have both continuous and discrete quantity in the same subject? Then, it remembers that it has continuous quantity in its essence, and discrete quantity in its correlatives.

31. With the first species of rule G we ask about the property proper to the vegetative power. We answer that its proper quality is the general quality from which all particular qualities descend; for instance, the hot qualities of pepper and garlic descend from the general quality of heat, and the coldness of lettuce and squash descends from the general quality of cold, etc. As the properties proper to the vegetative power derive from general elemental qualities, so does the quantity of the vegetative power derive from the general quantity of the elementative. We say that the general property or quality of the vegetative power is that of transmuting one substance into another substance.

32. With the second species of rule G we ask what the appropriated quality of the vegetative power is. We answer that it is the transmutation of species, which proceeds as the elementative appropriates its quantity, quality etc. to the vegetative power; and vegetation, inasmuch as it is effected by the movement of heaven, is an appropriated quality of the vegetative power.

33. With rule H we ask how the vegetative exists in time. But the intellect has difficulty in answering this, until it remembers that the vegetative receives influence from the elementative whereby it exists in time and movement as well as in quantity, quality etc. This is because the elementative essence is punctual and linear, which is not at all the case with the vegetative. This is signified by rules C, D and K to the diligent reader.

34. With rule I we ask where the vegetative vegetates vegetated things. The answer is that it does this in its own intrinsic and consubstantial vegetable part, apart from which and without which it cannot vegetate, just as the heater deprived of its intrinsic heatable part cannot heat anything. The vegetative power's locality can be known with rules C, D and K. And the vegetative power attains substance because it participates with substance through its contact with it.

35. With the first rule K we ask how the vegetative vegetates vegetated things. We say that it vegetates them by means of the mode of its correlatives. The vegetative places in its intrinsic vegetable part the form and matter that come to it from the elementative; and in this vegetable part it turns one substance into another as the vegetative strips the elementative form and matter it acquired externally and clothes a new vegetated being with new form and matter. And many other processes concur with this one, such as the process of proportioning, the processes of generation, corruption, privation, growth and so on, as the vegetative power places one part in another, the parts in the whole and conversely while the whole transmits its likeness to the things it assimilates.

36. With the second rule K we ask what the vegetative vegetates vegetated things with. We answer that it vegetates them with its own correlatives, namely its co-essential vegetative, vegetable and vegetating parts; the vegetative, in its intrinsic vegetable part, vegetates all peregrine vegetated things through the act of vegetating. In addition, it vegetates with the principles of this art, namely goodness, greatness etc. The things said here about the

vegetative are sufficient, although much more can be said about it; everything that can be said about it is implicitly contained in what we just said.
