Aristotle (384-322 BC)

Greek philosopher who advocated reason and moderation. He maintained that sense experience is our only source of knowledge, and that by reasoning we can discover the essences of things, that is, their distinguishing qualities. In his works on ethics and politics, he suggested that human happiness consists in living in conformity with nature. He derived his political theory from the recognition that mutual aid is natural to humankid, and refused to set up any one constitution as universally ideal. Of Aristotle's works, around 22 treatises survive, dealing with logic, metaphysics, astronomy, meteorology, biology, psychology, ehtics, politics, and literary criticism.

Aristotle was born in Stagira in Thrace and studied in Athens, where he became a distinguished member of the Academy founded by Plato. He then opened a school at Assos. At this time he regarded himself as a Platonist, but his subsequent thought led him further from the traditions that had formed his early background and he was later critical of Plato. In about 344 BC he moved to Mytilene in Lesvos, and devoted the next two years to the study of natural history. Meanwhile, during his residence at Assos, he had married Pythias, niece and adopted daughter of Hermeias, ruler of Atarneus.

In 342 BC he accepted an invitation from Philip II of Macedon to go to Pella as tutor to Philip's son Alexander the Great. In 335 BC he opened a school in the Lyceum (grove sacred to Apollo) in Athens. It became known as the 'peripatetic school' because he walked up and down as he talked, and his works are a collection of his lecture notes. When Alexander died in 323 BC, Aristotle was forced to flee to Chalcis, where he died.

Among his many contributions to political thought were the first systematic attempts to distinguish between different forms of government, ideas about the role of law in the state, and the conception of a science of politics.

In the Poetics, Aristotle defines tragic drama as an imitation (mimesis) of the actions of human beings, with character subordinated to plot. The audience is affected by pity and fear, but experiences a purgation (catharsis) of these emotions through watching the play. The second book of the Peotics, on comedy, is lost. The three books of the Rhetoric form the earliest analytical discussion of the techniques of persuasion, and the last presents a theory of the emotions to which a speaker must appeal.

His works were lost to Europe after the decline of Rome, but they were reintroduced in the Middle Ages by Arab and Jewish scholars and became the basis of medieval scholasticism.

His major writings on cosmology, or astronomy, are brought together in the four-volume Pari ouranou/On the Heavens. Aristotle rejected the notion of infinity and the notion of a vacuum. A vacuum he held to be impossible because an object moving in it would meet no resistance and would therefore attain infinite velocity. Space could not be infinite, because in Aristotle's view, the universe consisted of a series of concentric spheres which rotated around the centrally placed, stationary Earth. If the outermost sphere were an infinite distance from the Earth, it would be unable to complete it's rotation within a finite period of time, in paricular within the 24-hour period in which the stars, fixed, as Aristotle believed, to the sphere, rotated around the Earth.

Aristotle's work in astronomy also included proving that the Earth was spherical. He observed that the Earth cast a circular shadow on the Moon during an eclipse and he pointed out that as one travelled north or south, the stars changed their positions. Aristotle overestimated the Earth's diameter by only 50%.

Aristotle saw nature as always striving to perfect it self. The principle of life he termed a soul, which he regarded as the form of the living creature, not as a substance separable from it. The intellect, he believed, can discover in sense impressions the universal, and since the soul thus transcends matter, it must be immortal. Art embodies nature, but in a more perfect fashion, its end being the purifying and ennobling of the affections. The essence of beauty is order and symmetry. Aristotle also first classified organisme into species and genera.

HUJAN

Hujan lagi...Hujan lagi...Cape deh, bulan Februari memang identik banget dengan musim hujan. Musim hujan mengakibatkan banyak aktifitas manusia yang tersita. Tapi ada enaknya juga loh, gara-gara hujan di sekolah aku jadi tidak bisa upacara, karena aku paling malas kalau upacara, aku sering pingsan, makanya aku senang banget kalau hujan pas hari senin, biar tidak upacara gitu.
Karena hujan yang terus menerus, mengakibatkan banjir dimana-mana dan menelan banyak korban jiwa, apalagi waktu tahun 2007, rumah aku kebanjiran loh, BT deh... Aku mengungsi di rumah tetangga aku yang tidak terkena banjir, sudah gitu mati lampu lagi, ah...makin BT aja...
Banjir juga dapat merusak padi-padi yang ada di desa, akibatnya masyarakat kekurangan bahan pangan dan kelaparan. Para petani pun juga tak bisa apa-apa, sebab mereka pun tak punya persediaan bahan pangan dan bantuan pun sulit untuk memasuki daerah tersebut karena banjir yang terlalu besar.
Banjir yang paling besar terdapat di Jakarta karena di Jakarta penduduknya sangat padat dan sampahnya pun melimpah. Warga DKI Jakarta pun kurang kesadarannya. Mereka membuang sampah seenaknya dan tidak memperdulikan apa akibat yang mereka lakukan itu.
Pemerintah sudah berusaha sebisa mungkin untuk memperbaiki saluran-saluran yang tersumbat dan memberantas rumah-rumah liar yang terdapat di bantaran kali karena itu salah satu penyebab utama terjadinya banjir.
