Definition 3 expresses philosophy as we are going to understand it in this class. Philosophy in this sense is (like definition 1, but unlike definition 2) an activity : it is something you do . In particular, doing philosophy is using our rationality in trying to figure out the answers to difficult questions (related to any subject matter).
Ethics is a branch of philosophy which assesses explanatory theories concerning the moral rightness or wrongness of different kinds of actions, as well as the moral goodness or badness of different kinds of emotions, intensions, volitions and states of character.
Epistemology (from Greek ἐπιστήμη - episteme-, "knowledge, science" + λόγος, "logos") or theory of knowledge is the branch of philosophy concerned with the nature and scope (limitations) of knowledge. Much of the debate in this field has focused on analyzing the nature of knowledge and how it relates to similar notions such as truth, belief, and justification. It also deals with the means of production of knowledge, as well as skepticism about different knowledge claims. The term was introduced into English by the Scottish philosopher James Frederick Ferrier (1808–1864). Wiki
It addresses the questions: • What is knowledge? • How is knowledge acquired? • What do people know? • How do we know what we know? Wiki
Metaphysics is the branch of philosophy which assesses world views. A world view is any more or less complete enumeration of the most general categories of being, coupled with a definition of each of those categories, an account of the way in which things in those categories are related to each other, as well as an account of the ultimate origins of things. Metaphysics (G. meta ta physica – “after the Physics”) ~ a science that studies all beings insofar as they are beings. Ontology (G. ontologia; onto – “being” and logia – “talking”; “talking about being”) ~ a metaphysical study of all realities/beings insofar as they exist. Real ~ extra-mental or that whose existence is independent of the human mind. Logical ~ one which is considered as intra-mental (e.g., numbers, geometrical points, mathematical objects, time); they don’t have “real existence” in the outside world. Ideal ~ one which is purely intra-mental; those whose existence lies only inside the human mind (e.g., flying-horse, golden mountain, square-circle) Approaches to Philosophy Special Metaphysics ~ studies beings specially or specifically, when it studies the world (cosmology), God (theodicy), and man (rational psychology). Cosmology ~ a metaphysical science which studies the general nature of the world or the structure and history of the universe. Theodicy or Natural Theology ~ a metaphysical science which studies the nature, operations, and attributes of God or the study about God in the context of reason, not of faith. Rational Psychology ~ a metaphysical science which treats man’s nature as a being endowed with reason and intellect which studies the rational metaphysics of the human soul

Socrates (c.469-399BCE)called philosophy downfrom the skies.’ (Cicero)Teacher of Plato
The Death of Socrates(Jacques-Louis David, 1787)• Socrates most important contribution to Western thought is his dialogical methodof enquiry, known as the Socratic method where one finds truth by eliminatingwhat one knows to be false by following a line of enquiry to a contridiction.• Socrates believed that his wisdom sprung from an awareness of his ownignorance. He knew that he knew nothing, and that all error came out ofignorance.• Socrates believed that the best way for people to live was to focus not onaccumulating possessions, but on self-development. Socrates believed that “idealsbelong in a world that only the wise man can understand” making the philosopherthe only type of person suitable to govern others.• Socrates views angered the leaders of Athens and he was accused of being anti-democratic and corrupting the youth of the country. Though neither chargedemanded the death sentence the number of jurors who voted to condemn himto death was actually larger than the number who voted to convict him in the firstplace. In other words even jurors who believed he was innocent condemned himto death. If he was not anti-democratic before, this most certainly convinced him,and others of the flaws in a democratic system.• Though Socrates left no writings of his own his exploits have been chronicled by anumber of ancient writers, formost among them Plato whose works are based onthe teachings of Socrates.
Ancient Greek PhilosophersSchool of Athens - Raphael Sanzio
“The unexamined life is not worth living. ...Wisdom begins in wonder. ... There is onlyone good, knowledge, and one evil,ignorance.”(Socrates, 469 - 399 B.C.)
“The philosopher is in love with truth, that is, notwith the changing world of sensation, which isthe object of opinion, but with the unchangingreality which is the object of knowledge.”(Plato, 429 - 347 B.C.)
“We are what we repeatedly do. Excellence, then, is notan act, but a habit. ... At his best, man is the noblestof all animals; separated from law and justice he isthe worst.”(Aristotle, 384 - 322 B.C.)

What do you think about the allegories made?
Anti-Democratic Plato• Most perfect form of government: “PhilosopherKings” (i.e. very smartest) rule over an essentiallycommunistic society• Why Philosopher Kings?– Plato believed they alone possess the intellectualcapacity to achieve the highest form of humancontemplation• Such penetrating powers of insight necessary to distinguishbetween truth (i.e. that which is eternal and unchanging andtherefore is “really real”) from that which is untrue(changeable stimuli received by our faulty instruments ofperception that serve to trick us into thinking thatsomething is in fact “real”)

Aristotle, continued• Believed in the Golden Mean– i.e. all things follow the middle course; by avoidingextremes, one will enjoy a maximum of happiness anda minimum of pain• Called the “encycolpedist” as he had a profoundlove of order• Numerous fields of scientific study he eitherinvented or contributed to:– Logic, biology, zoology, botany, psychology,chemistry, astronomy, cosmology, metaphysics,ethics, political theory, constitutional history, historyof sport
Aristotle, continued• Founder of scientific method– A valid and reliable process by which all scientificanalyses of a given phenomenon could take place• Led to explosive advances in the Greekscientists’ capacity to conduct scientificresearch• Middle Ages’ scholars felt Aristotle knewalmost as much as God, therefore called him“The Philosopher”
Elements of the Art of Rhetoric• Ethos = Ethics– Appeal based on the trustworthiness/character of the speaker– Relies on the reputation of the author• Logos = Logic– Appeal based on logic or reason– Found primarily in scholarly articles and corporate financial reports• Pathos = Pathetic, sympathy, empathy– Appeal based on emotion– Found in advertisements– The more people react without full consideration for the “why,” themore effective an argument can be– Although it can be manipulative, it is the cornerstone of movingpeople to action
Legacy of Greek Philosophers• Taught us how to think• Provided a great deal of insight into the naturalworld• Provided many of the most profound andmeaningful answers to the great philosophicalquestions that have befuddled humans since thedawn of civilization• Provided a comprehensive, valid, and reliablemethod by which we could test whether or not agiven idea is true
ARISTOTLE• Aristotle is a toweringfigure in ancientGreek philosopher,making contributionto logic, metaphysics,mathematics, biology,botany, ethics,politics, agriculture,medicine, dance andtheater.
• He was a student of Plato who in turn studiedunder Socrates. He was more empirically-minded than Plato or Socrates and is famousfor rejecting Plato’s theory of forms.
• As a prolific writerand polymath,Aristotle radicallytransformed most, ifnot all, areas ofknowledge hetouched. It is nowonder that Aquinasreferred to him simplyas “The Philosopher.”In his lifetime,Aristotle wrote asmany as 200 treatises,of which only 31survive.Saint Thomas AquinasSaint Thomas Aquinas“TheSocrates
• Aristotle was the first to classify areas of human knowledgeinto distinct disciplines such as mathematics, biology, andethics. Some of these classifications are still used today.• As the father of the field of logic, he was the first todevelop a formalized system for reasoning. Aristotleobserved that the validity of any argument can bedetermined by its structure rather than its content. Aclassic example of a valid argument is his syllogism: All menare mortal; Socrates is a man; therefore, Socrates ismortal.MathematicsBiology Ethics
ARISTOTLE’S LIFE• Aristotle was born in 384BCE at Stagirus, a nowextinct Greek colony andseaport on the coast ofThrace. His fatherNichomachus was courtphysician to King Amyntasof Macedonia, and fromthis began Aristotle’s longassociation with theMacedonian Court, whichconsiderably influenced hislife.
• While he was still a boy his father died. At age 17 his guardian,Proxenus, sent him to Athens, the intellectual center of the world,to complete his education. He joined the Academy and studiedunder Plato, attending his lectures for a period of twenty years.ARISTOTLE’S LIFE
• It is reported that Aristotle’s writings wereheld by his student Theophrastus, whohad succeeded Aristotle in leadership ofthe Peripatetic School.ARISTOTLE’S WRITINGSThe works of Aristotlefall under threeheadings:• Among his writings of a popular nature the onlyone which we possess of any consequence is theinteresting tract On the Polity of the Athenians.
ARISTOTLE’S LOGIC• Aristotle’s writings on the general subject of logic weregrouped by the later Peripatetics under the name Organon,or instrument. From their perspective, logic and reasoningwas the chief preparatory instrument of scientificinvestigation. Aristotle himself, however, uses the term“logic” as equivalent to verbal reasoning.“Organon”Peripatetics
ARISTOTLE’S METAPHYSICS• Aristotle’s editors gave the name“Metaphysics” to his works on firstphilosophy, either because theywent beyond or followed after hisphysical investigations. Aristotlebegins by sketching the history ofphilosophy. For Aristotle,philosophy arose historically afterbasic necessities were secured. Itgrew out of a feeling of curiosityand wonder, to which religiousmyth gave only provisionalsatisfaction.
• Aristotle sees the universe as a scale lying between the twoextremes: form without matter is on one end, and matterwithout form is on the other end. The passage of matter intoform must be shown in its various stages in the world ofnature. To do this is the object of Aristotle’s physics, orphilosophy of nature. It is important to keep in mind that thepassage from form to matterwithin nature is a movementtowards ends or purposes.Everything in nature has itsend and function, and nothingis without its purpose. Everywherewe find evidences of design and rational plan.ARISTOTLE’S PHILOSOPHY OF NATURE
ARISTOTLE’S THE SOUL ANDPSYCHOLOGY• Soul is defined by Aristotle asthe perfect expression orrealization of a natural body.From this definition it followsthat there is a closeconnection betweenpsychological states, andphysiological processes. Bodyand soul are unified in thesame way that wax and animpression stamped on it areunified.
ARISTOTLE’S ETHICS• Ethics, as viewed by Aristotle, is anattempt to find out our chief endor highest good: an end which hemaintains is really final. Thoughmany ends of life are only means tofurther ends, our aspirations anddesires must have some final objector pursuit. Such a chief end isuniversally called happiness. Butpeople mean such different thingsby the expression that he finds itnecessary to discuss the nature of itfor himself.
• Aristotle does not regard politicsas a separate science fromethics, but as the completion,and almost a verification of it.The moral ideal in politicaladministration is only a differentaspect of that which also appliesto individual happiness. Humansare by nature social beings, andthe possession of rationalspeech (logos) in itself leads usto social union.ARISTOTLE’S POLITICS
ARISTOTLE’S ART AND POETICS• Art is defined by Aristotle as therealization in external form of atrue idea, and is traced back tothat natural love of imitationwhich characterizes humans, andto the pleasure which we feel inrecognizing likenesses. Arthowever is not limited to merecopying. It idealizes nature andcompletes its deficiencies: itseeks to grasp the universal typein the individual phenomenon.
