As in the previous chapter we divided the inner human drawing in speculative and practical, so it is necessary to divide the latter in its particular species, to differentiating the more easily and because, limiting it, to reach that Inner representation that is our own prospects, painting, sculpture and architecture. So the practical drawing is morally and artificially divided; And even if this division seems unantemeted or at least unusual, it is still real and much encountered at the moral philosophers the moral drawing is, to say so, the father of all virtues and good, both cit and common. The artificial drawing is the father of any artificial works, the dissemination of all and the adornment of the nature. So the practical intellect of man, which we talked about before, is not only known, but it is also the main cause of and orands two kinds of actions: those called virtuous philosophers, either inner or exterior, by the thoughts of thoughts , words and virtuous facts, and those called artificial activities, both cit and outer interiors, such as understanding the rationale of paint, carving and built, and then, out, painting with the pen, sculpting with chisel and building with Visited tools. As such, the representation formed in this intellect is the cause of any virtue and of our good, either private or general; And by representing this intellect, linked to the second category of shares, it is the cause of artificial things, so pleasant to our eyes, adorning nature and embellish the world. The own purpose of moral philosophy is to investigate all human and exterior human actions for a particular or common virtuous purpose. To achieve this goal, it is necessary first to think about those actions, the purpose for which it is oranduled and the way it is to be oranduled, thus alcouncing a practical representation of the right practice to act.
For example, as a Captain who wants to fight the enemy in the field open or bathing his Citadel, in order to be able to victor, towards the peace and political happiness of the state or should be first investigated all the necessary for this purpose and to scrutin the ways, means, gains, dangers and the like, forming a drawing; Then, according to him, he will orand his hosting, he will move it, will lead it to the fight and victory. And with the help of this moral practical representation, man not only acts virtuously, but acquires virtue, as the Captain, through m any actions on the batches, interests, not only that of the body, but also of the soul; Thus, it gets uninfront and brave, underacting from no fight how inappropriate. And what I said about the captain and the virtue of the land can be said about every man and any other moral virtue. It can therefore be seen not only that this drawing or representation is very necessary for mental or virtuous operations, but also that kind of knowledge is the limit and object; Namely, it is not the object or limit of speculative knowledge, as this is not the cause of moral virtue, because it only deals with the contemplation of things in general and not with the particular actions of virtue. And it is not the proper line and object either practical knowledge in general because of the same cause is not useful, but is the limit and the subject of particular and singular practical knowledge. For, to tell the truth, if someone wants to become virtuous, for example, to be puddled and cast, too little will use the fact that it would lie metaphysician, mathematician, philosopher or logician - than just accidentally. As little it will help themselves and know what virtue, virtuous action, powder and chastity is generally.
But if they will in particular form a concept, and then it will put into practice, then it will become virtuous, you will acquire the learning of virtue and will act accordingly. These will be defined and exemplified in Chapter XV. That is why the moral philosophers say the moral science is all the more attached to how much practice is closer to what we want and therefore in this science, as the drawing is more particular, more limited and restricted, the more it is Determined the combination of virtuous shares. Let's move on now. We translated "Scienza Ragionevole" through the science of rationale, that is, Silogistics, because the three operations mentioned seem to follow the path of Silogism, from premise to conclusion. We have kept the original term of real science, although those listed within it are the sciences called by Aristotle theoretical (speculative). To these, Zuccaro added here and the logic, which the trainee did not integrate among the science, counting it a method (hence the title of organon subsequently given his logic works).
That is, philosophical disciplines that year as a man as a man as a social being. Dealt, the division here by Zuccaro seems to be based on the distinction made by Aristotle in ethics (vi) between practical sciences (which they would correspond to the moral drawing) and those of creation (which would correspond to the artificial drawing).
