Security needs are met by the military class, and political leadership is provided by the philosopher-kings. A particular person's class is determined by an educational process that begins at birth and proceeds until that person has reached the maximum level of education compatible with interest and ability. Those who complete the entire educational process become philosopher-kings. They are the ones whose minds have been so developed that they are able to grasp the Forms and, therefore, to make the wisest decisions.
Indeed, Plato's ideal educational system is primarily structured so as to produce philosopher-kings. Plato associates the traditional Greek virtues with the class structure of the ideal state. Temperance is the unique virtue of the artisan class; courage is the virtue peculiar to the military class; and wisdom characterizes the rulers. Justice, the fourth virtue, characterizes society as a whole.
The just state is one in which each class performs its own function well without infringing on the activities of the other classes. Plato divides the human soul into three parts: the rational part, the will, and the appetites. The just person is the one in whom the rational element, supported by the will, controls the appetites.
An obvious analogy exists here with the threefold class structure of the state, in which the enlightened philosopher-kings, supported by the soldiers, govern the rest of society. Plato's ethical theory rests on the assumption that virtue is knowledge and can be taught, which has to be understood in terms of his theory of Forms. As indicated previously, the ultimate Form for Plato is the Form of the Good, and knowledge of this Form is the source of guidance in moral decision making.
Plato also argued that to know the good is to do the good. The corollary of this is that anyone who behaves immorally does so out of ignorance. This conclusion follows from Plato's conviction that the moral person is the truly happy person, and because individuals always desire their own happiness, they always desire to do that which is moral.
This is not a surprise, if we just consider the size and complexity of the philosophical domain. If representation consist in depicting an arrangement of elements in logical space, then logical space itself can't be depicted since it is itself not an arrangement of anything ; rather logical form is a feature of an arrangement of objects and thus it can be properly expressed that is depicted in language by an analogous arrangement of the relevant signs in sentences which contain the same possibilities of combination as prescribed by logical syntax , hence logical form can only be shown by presenting the logical relations between different sentences.

Plato had an essentially antagonistic view of art and the artist, although he approved of certain religious and moralistic kinds of art. Again, his approach is related to his theory of Forms. A picture of the flower is, therefore, two steps removed from reality. This also meant that the artist is two steps removed from knowledge, and, indeed, Plato's frequent criticism of the artists is that they lack genuine knowledge of what they are doing. Artistic creation, Plato observed, seems to be rooted in a kind of inspired madness.
Plato's influence throughout the history of philosophy has been monumental. When he died, Speusippus became head of the Academy. The school continued in existence until AD , when it was closed by the Byzantine emperor Justinian I, who objected to its pagan teachings. Plato's impact on Jewish thought is apparent in the work of the 1st-century Alexandrian philosopher Philo Judaeus. Neoplatonism, founded by the 3rd-century philosopher Plotinus, was an important later development of Platonism.
The theologians Clement of Alexandria, Origen, and St. Augustine were early Christian exponents of a Platonic perspective. Platonic ideas have had a crucial role in the development of Christian theology and also in medieval Islamic thought. During the Renaissance, the primary focus of Platonic influence was the Florentine Academy, founded in the 15th century near Florence.
In England, Platonism was revived in the 17th century by Ralph Cudworth and others who became known as the Cambridge Platonists.

Aristotle BC , Greek philosopher and scientist, who shares with Plato and Socrates the distinction of being the most famous of ancient philosophers. Aristotle was born at Stagira, in Macedonia, the son of a physician to the royal court. At the age of 17, he went to Athens to study at Plato's Academy. He remained there for about 20 years, as a student and then as a teacher.
There he counseled Hermias and married his niece and adopted daughter, Pythias. After Hermias was captured and executed by the Persians in BC, Aristotle went to Pella, the Macedonian capital, where he became the tutor of the king's young son Alexander, later known as Alexander the Great. In , when Alexander became king, Aristotle returned to Athens and established his own school, the Lyceum. Upon the death of Alexander in BC, strong anti-Macedonian feeling developed in Athens, and Aristotle retired to a family estate in Euboea.
He died there the following year. Aristotle, like Plato, made regular use of the dialogue in his earliest years at the Academy, but lacking Plato's imaginative gifts, he probably never found the form congenial. Apart from a few fragments in the works of later writers, his dialogues have been wholly lost. Aristotle also wrote some short technical notes, such as a dictionary of philosophic terms and a summary of the doctrines of Pythagoras. Of these, only a few brief excerpts have survived. Still extant, however, are Aristotle's lecture notes for carefully outlined courses treating almost every branch of knowledge and art.
The texts on which Aristotle's reputation rests are largely based on these lecture notes, which were collected and arranged by later editors. His works on natural science include Physics, which gives a vast amount of information on astronomy, meteorology, plants, and animals.
His writings on the nature, scope, and properties of being, which Aristotle called First Philosophy Prote philosophia , were given the title Metaphysics in the first published edition of his works 60? BC , because in that edition they followed Physics. To his son Nicomachus he dedicated his work on ethics, called the Nicomachean Ethics.
Other essential works include his Rhetoric, his Poetics which survives in incomplete form , and his Politics also incomplete.
Perhaps because of the influence of his father's medical profession, Aristotle's philosophy laid its principal stress on biology, in contrast to Plato's emphasis on mathematics. Aristotle regarded the world as made up of individuals substances occurring in fixed natural kinds species. Each individual has its built-in specific pattern of development and grows toward proper self-realization as a specimen of its type.
https://reminder.regexbyte.com/libraries/the/2297-edyta-grniak-nowy.php Growth, purpose, and direction are thus built into nature. Although science studies general kinds, according to Aristotle, these kinds find their existence in particular individuals. Science and philosophy must therefore balance, not simply choose between, the claims of empiricism observation and sense experience and formalism rational deduction. One of the most distinctive of Aristotle's philosophic contributions was a new notion of causality. Earlier Greek thinkers had tended to assume that only one sort of cause can be really explanatory; Aristotle proposed four. These four causes are the material cause, the matter out of which a thing is made; the efficient cause, the source of motion, generation, or change; the formal cause, which is the species, kind, or type; and the final cause, the goal, or full development, of an individual, or the intended function of a construction or invention.
Thus, a young lion is made up of tissues and organs, its material cause; the efficient cause is its parents, who generated it; the formal cause is its species, lion; and its final cause is its built-in drive toward becoming a mature specimen. In different contexts, while the causes are the same four, they apply analogically. Thus, the material cause of a statue is the marble from which it was carved; the efficient cause is the sculptor; the formal cause is the shape the sculptor realized—Hermes, perhaps, or Aphrodite; and the final cause is its function, to be a work of fine art.
In each context, Aristotle insists that something can be better understood when its causes can be stated in specific terms rather than in general terms.
Thus, it is more informative to know that a sculptor made the statue than to know that an artist made it; and even more informative to know that Polycleitus chiseled it rather than simply that a sculptor did so. Aristotle thought his causal pattern was the ideal key for organizing knowledge.
His lecture notes present impressive evidence of the power of this scheme. Some of the principal aspects of Aristotle's thought can be seen in the following summary of his doctrines, or theories. In astronomy, Aristotle proposed a finite, spherical universe, with the earth at its center. The central region is made up of four elements: earth, air, fire, and water. Thus, terrestrial motion is always linear and always comes to a halt.
