What method, art or study will lead us to the goal we are certain, namely, the Good, the first Principle, the Divinity, by a demonstration which itself can serve to raise the soul to the superior world?
He who is to be promoted to that world should know everything, or at least, as says (Plato), he should be as learned as possible. In his first generation he should have descended here below to form a philosopher, a musician, a lover. That is the kind of men whose nature makes them most suitable to be raised to the intelligible world.
But how are we going to raise them? Does a single method suffice for all? Does not each of them need a special method? Doubtless. There are two methods to follow: the one for those who rise to the intelligible world from here below, and the other for those who have already reached there. We shall start by the first of these two methods; then comes that of the men who have already achieved access to the intelligible world, and who have, so to speak, already taken root there. Even these must ceaselessly progress till they have reached the summit; for one must stop only when one has reached the supreme term.

HOW THE MUSICIAN RISES TO THE INTELLIGIBLE WORLD.
The musician allows himself to be easily moved by beauty, and admires it greatly; but he is not able by himself to achieve the intuition of the beautiful. He needs the stimulation of external impressions. ... He will have to be taught that what excites his admiration in these things is their intelligible harmony, the beauty it contains, and, in short, beauty absolute, and not particular. …
HOW THE LOVER RISES TO THE INTELLIGIBLE.
The musician can rise to the rank of the lover, and either remain there, or rise still higher. But the lover has some reminiscence of the beautiful; but as here below he is separated from it, he is incapable of clearly knowing what it is. Charmed with the beautiful objects that meet his views, he falls into an ecstasy. He must therefore be taught not to content himself with thus admiring a single body, but, by reason, to embrace all bodies that reveal beauty; showing him what is identical in all, informing him that it is something alien to the bodies, which comes from elsewhere, and which exists even in a higher degree in the objects of another nature; citing, as examples, noble occupations, and beautiful laws. He will be shown that beauty is found in the arts, the sciences, the virtues, all of which are suitable means of familiarizing the lover with the taste of incorporeal things. He will then be made to see that beauty is one, and he will be shown the element which, in every object, constitutes beauty. From virtues he will be led to progress to intelligence and essence, while from there he will have nothing else to do but to progress towards the supreme goal.
HOW THE PHILOSOPHER RISES TO THE INTELLIGIBLE WORLD.
The philosopher is naturally disposed to rise to the intelligible world. Borne on by light wings, he rushes thither without needing to learn to disengage himself from sense-objects, as do the preceding men. His only uncertainty will concern the road to be followed; all he will need will be a guide. He must therefore be shown the road; he must be helped to detach himself entirely from sense-objects, himself already possessing, as he does, the desire, being since a long while already detached therefrom by his nature. For this purpose he will be invited to apply himself to mathematics, so as to accustom him to think of incorporeal things, to believe in their existence. Being desirous of instruction, he will learn them easily; as, by his nature, he is already virtuous, he will need no more than promotion to the perfection of virtue. After mathematics, he will be taught dialectics, which will perfect him.
WHAT DIALECTICS IS.
What then is this dialectics, knowledge of which must be added to mathematics? It is a science which makes us capable of reasoning about each thing, to say what it is, in what it differs from the others, in what it resembles them, where it is, whether it be one of the beings, to determine how many veritable beings there are, and which are the objects that contain nonentity instead of veritable essence. This science treats also of good and evil; of everything that is subordinated to being, the Good, and to its contrary; of the nature of what is eternal, and transitory. It treats of each matter scientifically, and not according to mere opinion. Instead of wandering around the sense-world, it establishes itself in the intelligible world; it concentrates its whole attention on this world, and after having saved our soul from deceit, dialectics “pastures our soul in the meadow of truth,” as thought Plato. Then it makes use of the Platonic method of division to discern ideas, to define each object, to rise to the several kinds of essences as thought Plato; then, by thought concatenating all that is thence derived, dialectics continues its deductions until it has gone through the whole domain of the intelligible. Then, by reversing, dialectics returns to the very Principle from which first it had started out. Resting there, because it is only in the intelligible world that it can find rest, no longer needing to busy itself with a multitude of objects, because it has arrived at unity, …”
