Men acquire a particular quality by constantly acting a particular way… you become just by performing just actions, temperate by performing temperate actions, brave by performing brave actions. – Aristotle

Aristotle (/ˈærɪˌstɒtəl/;[1] Greek: Ἀριστοτέλης [aristotélɛːs], Aristotélēs; 384–322 BCE)[2] was a Greek philosopher born in Stagirus in 384 BCE. His father, Nicomachus, died when Aristotle was a child and he lived under a guardian’s care. At the age of eighteen, he joined Plato’s Academy in Athens and remained until the age of thirty-seven, around 347 BCE. His writings cover many subjects, including physics, metaphysics, poetry, theater, music, logic, rhetoric, linguistics, politics, government, ethics, biology, and zoology. Aristotle’s writings were the first to create a comprehensive system of Western philosophy, encompassing ethics, aesthetics, logic, science, politics, and metaphysics. Shortly after Plato died Aristotle left Athens. With the request of Philip of Macedonia he became a tutor for Alexander in 356–323 BCE. According to the Encyclopædia Britannica, “Aristotle was the first genuine scientist in history. . . . Every scientist is in his debt.”

Aristotle achieved merit through teaching Alexander the Great. This distinction allowed him many opportunities, including an abundance of supplies. He established a library in the Lyceum which aided in the production of many of his hundreds of books. The fact that Aristotle was a pupil of Plato contributed to his former views of Platonism, but following Plato’s death, Aristotle immersed himself in empirical studies and shifted from Platonism to empiricism .[3] He believed all peoples concepts and all of their knowledge was ultimately based on perception. Aristotle’s views on natural sciences, including philosophy of the mind, body, sensory experience, memory, and biology represent the groundwork underlying many of his works.

ristotle’s views on the physical sciences profoundly shaped medieval scholarship, and their influence extended well into the Renaissance, although they were ultimately replaced by Newtonian physics. In the zoological sciences, some of his observations were confirmed to be accurate only in the 19th century. His works contain the earliest known formal study of logic, which was incorporated in the late 19th century into modern formal logic.

In metaphysics, Aristotelianism had a profound influence on philosophical and theological thinking in the Islamic and Jewish traditions in the Middle Ages, and it continues to influence Christian theology, especially the scholastic tradition of the Catholic Church. Aristotle was well known among medieval Muslim intellectuals and revered as ‘المعلم الأول’ – “The First Teacher”.

His ethics, though always influential, gained renewed interest with the modern advent of virtue ethics. All aspects of Aristotle’s philosophy continue to be the object of active academic study today. Though Aristotle wrote many elegant treatises and dialogues (Cicero described his literary style as “a river of gold”),[4] it is thought that the majority of his writings are now lost and only about one-third of the original works have survived.[5]


Aristotle’s psychology, given in his treatise On the Soul (peri psyche, often known by its Latin title De Anima), posits three kinds of soul (“psyches”): the vegetative soul, the sensitive soul, and the rational soul. Humans have a rational soul. This kind of soul is capable of the same powers as the other kinds: Like the vegetative soul it can grow and nourish itself; like the sensitive soul it can experience sensations and move locally. The unique part of the human, rational soul is its ability to receive forms of other things and compare them.

For Aristotle, the soul (psyche) was a simpler concept than it is for us today. By soul he simply meant the form of a living being. Since all beings are composites of form and matter, the form of living beings is that which endows them with what is specific to living beings, e.g. the ability to initiate movement (or in the case of plants, growth and chemical transformations, which Aristotle considers types of movement).[59]

Practical philosophy


Main article: Aristotelian ethics

Aristotle considered ethics to be a practical rather than theoretical study, i.e., one aimed at becoming good and doing good rather than knowing for its own sake. He wrote several treatises on ethics, including most notably, the Nicomachean Ethics.

Aristotle taught that virtue has to do with the proper function (ergon) of a thing. An eye is only a good eye in so much as it can see, because the proper function of an eye is sight. Aristotle reasoned that humans must have a function specific to humans, and that this function must be an activity of the psuchē (normally translated as soul) in accordance with reason (logos). Aristotle identified such an optimum activity of the soul as the aim of all human deliberate action, eudaimonia, generally translated as “happiness” or sometimes “well being”. To have the potential of ever being happy in this way necessarily requires a good character (ēthikē aretē), often translated as moral (or ethical) virtue (or excellence).[60]

Aristotle taught that to achieve a virtuous and potentially happy character requires a first stage of having the fortune to be habituated not deliberately, but by teachers, and experience, leading to a later stage in which one consciously chooses to do the best things. When the best people come to live life this way their practical wisdom (phronesis) and their intellect (nous) can develop with each other towards the highest possible human virtue, the wisdom of an accomplished theoretical or speculative thinker, or in other words, a philosopher.[61]


Main article: Politics (Aristotle)

Like Aristotle, conservatives generally accept the world as it is; they distrust the politics of abstract reason – that is, reason divorced from experience.
Benjamin Wiker[62]

In addition to his works on ethics, which address the individual, Aristotle addressed the city in his work titled Politics. Aristotle considered the city to be a natural community. Moreover, he considered the city to be prior in importance to the family which in turn is prior to the individual, “for the whole must of necessity be prior to the part”.[63] He also famously stated that “man is by nature a political animal”. Aristotle conceived of politics as being like an organism rather than like a machine, and as a collection of parts none of which can exist without the others. Aristotle’s conception of the city is organic, and he is considered one of the first to conceive of the city in this manner.[64]

The common modern understanding of a political community as a modern state is quite different to Aristotle’s understanding. Although he was aware of the existence and potential of larger empires, the natural community according to Aristotle was the city (polis) which functions as a political “community” or “partnership” (koinōnia). The aim of the city is not just to avoid injustice or for economic stability, but rather to allow at least some citizens the possibility to live a good life, and to perform beautiful acts: “The political partnership must be regarded, therefore, as being for the sake of noble actions, not for the sake of living together.” This is distinguished from modern approaches, beginning with social contract theory, according to which individuals leave the state of nature because of “fear of violent death” or its “inconveniences.”[65]

Rhetoric and poetics

Aristotle considered epic poetry, tragedy, comedy, dithyrambic poetry and music to be imitative, each varying in imitation by medium, object, and manner.[66] For example, music imitates with the media of rhythm and harmony, whereas dance imitates with rhythm alone, and poetry with language. The forms also differ in their object of imitation. Comedy, for instance, is a dramatic imitation of men worse than average; whereas tragedy imitates men slightly better than average. Lastly, the forms differ in their manner of imitation – through narrative or character, through change or no change, and through drama or no drama.[67] Aristotle believed that imitation is natural to mankind and constitutes one of mankind’s advantages over animals.[68]

While it is believed that Aristotle’s Poetics comprised two books – one on comedy and one on tragedy – only the portion that focuses on tragedy has survived. Aristotle taught that tragedy is composed of six elements: plot-structure, character, style, thought, spectacle, and lyric poetry.[69] The characters in a tragedy are merely a means of driving the story; and the plot, not the characters, is the chief focus of tragedy. Tragedy is the imitation of action arousing pity and fear, and is meant to effect the catharsis of those same emotions. Aristotle concludes Poetics with a discussion on which, if either, is superior: epic or tragic mimesis. He suggests that because tragedy possesses all the attributes of an epic, possibly possesses additional attributes such as spectacle and music, is more unified, and achieves the aim of its mimesis in shorter scope, it can be considered superior to epic.[70]

Aristotle was a keen systematic collector of riddles, folklore, and proverbs; he and his school had a special interest in the riddles of the Delphic Oracle and studied the fables of Aesop.[71]
